Bertha Forecast Track Takes Storm Well South and East Of New England


Bertha Strengthens

August 3rd, 2014 at 11:23 pm by under General Talk, Tony's Pinpoint Weather Blog

Air Force aircraft investigating Tropical Storm Bertha have found stronger winds around the center of circulation….a jump from 45mph at 5pm to 65mph at 11pm! Strong thunderstorms to the east of the center have grown and become better organized.  Bertha is just to the north of the Bahamas.

Monday’s Outlook

August 3rd, 2014 at 10:29 pm by under General Talk, Tony's Pinpoint Weather Blog

After a mostly cloudy, damp, cool and showery weekend, we need a little sunshine.  I think we will see a much better day on Monday! Better beach weather. Better boating weather. Better anything weather.  There’s still the chance for showers on Monday, but at least we’ll have the sun.

Here’s how Monday will play out….

There’s an area of upper-level energy spinning over Pennsylvania. You can sorta make out a spin over the Keystone State on the satellite/radar loop.


Tropical Storm Bertha

August 3rd, 2014 at 6:59 pm by under General Talk, Tony's Pinpoint Weather Blog

The convection (shower/thunderstorm activity) around Bertha has become a little better organized today.  While looking pretty ragged on Saturday, it looks a little healthier today.  The system has sustained winds are 45mph.

Arthur_IR_650x366

At 5pm on Sunday, Bertha was near the Turks and Caicos Islands in the southeast Bahamas Islands.  The storm will begin to turn northward and then eventually northeastward away from the United States this week.

Interesting to note, the National Hurricane Center’s official forecast calls for Bertha to intensify into a Category 1 Hurricane with winds of 75mph on Wednesday as it passes well to our south and east.  We feel pretty confident that Bertha will stay out to sea.  We could, however, see some waves from Bertha, especially if the system strengthens to a strong tropical storm or  hurricane.  Below is a forecast of ocean waves for Wednesday….some of the large waves associated with Bertha could propagate our way mid to late week.  Surfers unite!

Sunday Showers, but not as Heavy

August 3rd, 2014 at 9:08 am by under Tony's Pinpoint Weather Blog

Some more showers to get through today, but overall, not as much rain as what we had on Saturday.  This morning, everyone has a good chance of getting showers.  They will be off/on and light for the most part (although anytime you have tropical moisture involved, you can’t completely rule out a quick downpour).

The best chance of showers arrives later morning into the early afternoon, and then the chance drops into the late afternoon.  Note the graph below:

Blog_One

As shown above, the chance of showers drops in the afternoon, but locations to the south and east of I-95 may hang onto the showers a bit longer.  Note the map below:

Sunday_Aft_Bloggggggggggg

 

If you are headed out today, bring the rain jacket or umbrella.  While it won’t be raining the entire time, some showers will still be passing through.  There may be a few slivers of sun late today, especially for western Rhode Island.  Have a good day! -Pete Mangione

 

 


Tropical Storm Bertha Latest

August 2nd, 2014 at 11:50 pm by under General Talk, Tony's Pinpoint Weather Blog

As of 11pm, Tropical Storm Bertha was moving through the Dominican Republic.  The poorly organized system was bringing some squally weather to the island.   Data from Hurricane Hunter aircraft and surface observations  continued to show no well-defined low-level circulation.  Despite some strong thunderstorms just to the north of the Domincan Republic, the system shows no real organization.  The National Hurricane Center mentioned that any advisories associated with Bertha could be dropped Sunday.

Embedly Powered

via Noaa

Bertha is expected to continue moving northwest toward the Bahamas during the next 2 days.  The same system moving through the Northeast on Sunday will help guide Bertha out to sea and away from the United States.

Also of note in the tropics, we are monitoring an area of disturbed weather over the Bahamas.   This is associated with a weak area of low pressure.   There is only a slight chance that this area could become a tropical depression in the next 24hours.   On Monday, conditions will become unfavorable for tropical cyclone development as upper-level winds will become too strong.

Sunday’s Outlook

August 2nd, 2014 at 10:59 pm by under General Talk, Tony's Pinpoint Weather Blog

Sunday will not be perfect, but it does not look like a washout either.

We are monitoring an area of showers off the North Carolina and Virginia coastlines.  This area of rain is being produced by energy in the upper-levels of the atmosphere interacting with a stalled front.   As this disturbance moves northward, the showers will arrive in our area Sunday morning.  I don’t think the showers will be as widespread as Saturday.

Less Frequent Showers This Evening

August 2nd, 2014 at 4:44 pm by under General Talk, Tony's Pinpoint Weather Blog

Rain fell pretty heavily for awhile today, especially near the south coast.  Here are some of the rainfall totals as of 4:30pm:

  • Block Island  1.15″
  • TF Green Airport  .18″
  • Smithfield  .15″
  • Newport .90″
  • Westerly .56″
  • Tiverton .79″
  • Taunton .41″
  • New Bedford .94″
  • Hyannis .71″

Detailed 7 Day Discussion » Current Conditions » Radar » Severe Weather » Closings » Signup for Alerts & Closings »

Hurricane Tracker » Storm Ready Resource Guide » Severe Weather » Ocean »

Looking ahead, we have big slug of rain to get through before things settle down a bit.  At 4:30pm, Live Pinpoint Doppler 12 Radar was picking up on more rain moving along the south coasts of RI and MA and headed northeastward.  This should clear RI by 5:30pm and MA by 6:30pm.

Storm_Radar_650x366

High resolution computer models indicate that a few more rain showers are possible after this batch of rain, but nothing that should last more than a few minutes.  If you are headed to one of the many outdoor activities this evening  (Charlestown Seafood Festival, New Bedford Portuguese Fest), bring the poncho.   There will be many dry periods this evening, but a few quick showers are possible.

Looking ahead to Sunday, there’s still the chance of showers, but not nearly as widespread or heavy in RI and and nearby MA and CT.  The best chance for showers will be to the south and east of Providence.  Notice what our RPM computer model is showing at noon for Sunday….showers closer to the south coast and over Southeastern, MA.

rpm_650x366

I’ll detail Sunday’s outlook even more in another blog post this evening.

Our Weekend Outlook…Saturday Update

August 2nd, 2014 at 8:32 am by under Tony's Pinpoint Weather Blog

Not a very good day for outdoor activities with showers moving through.  The showers look like they will be at the steadiest from late morning into the mid afternoon.  A few showers could be heavy with the threat of isolated downpours and thunderstorms.

RADAR_BloG

By the late  afternoon and night, there are signs that the steadiest of showers will shift to the south and east out towards Cape Cod.  This would leave the vast majority of our viewing area getting light and less frequent rain showers.

 SUNDAY: The majority of our computer models are keeping the core of moisture offshore for Sunday, giving us just some occasional showers.  However, we need to watch this forecast carefully.  Tropical moisture can be very tricky to forecast, and any little change in the track of the moisture could translate to big changes to the Sunday forecast.  IF the track of the storm were to shift west slightly,  areas south and east of I-95 have the best chance of seeing more frequent showers.

SundayCatets

 

BERTHA: As of Saturday morning, Bertha is still a tropical storm with winds of 50 mph.  The track from the National Hurricane Center still keeps it offshore form the mainland US into early next week.  Have a good day! -Pete Mangione

Weekend Update

August 1st, 2014 at 8:03 am by under Tony's Pinpoint Weather Blog

Updated Friday at 12:30PM

The chance for showers will increase as we head into the weekend.  The threat of showers (and even a few downpours) will be with us the entire weekend.  It is unlikely that it rains for the entire weekend, so if you are planning outdoor activities, be aware of the potential for interruptions.   Best chance of some heavy downpours? That may actually hold off until very early Sunday morning.

Rain_Tweet_f

 

However, the timing could still change so stay tuned as we look at more data through out the weekend.  I am optimistically putting in some sun for Sunday afternoon, but there is a risk that showers and downpours will still be there.

Tropical Storm Bertha

As of early afternoon, Bertha is a tropical storm with winds of 50 mph.  She will move to the northwest over the next several days, and then likely sit somewhere offshore from the mainland US by early next week.

150722W5_NL_sm

By next week, the forecast becomes very uncertain, so we will need to watch this system carefully.  As of now, it is not a threat to the mainland US.  -Pete Mangione

Quiet Now, But Weekend Trouble?

July 30th, 2014 at 11:54 am by under General Talk, Tony's Pinpoint Weather Blog

We had a taste of autumn across the Northeast this morning.  Low temperatures were in the 30s, 40s and 50s….yes 30s! Look at Saranac Lake, NY! Martha’s Vineyard (not on map) had a low of 49°!  Very dry air, little wind and clear skies allowed the temperatures to plummet through the night.  The average low for the date is 65° in Providence.

LOWS_TODAY_650x366

Our weather will be mostly dry through Thursday, but we’ll begin to see some changes as we head toward the weekend.

As I wrote about yesterday, it’ll start to feel stickier in Southern New England on Thursday as southwest winds will begin to bring more humid air into the region.  We’re not talking about oppressive humidity, but you’ll  likely notice the change through the day tomorrow.

 

Sitting offshore is a plume of tropical moisture.  You can see it on this NASA satellite image from Tuesday.

Good Evening from chief  meteorologist Tony Petrarca…

National Hurricane Center and the Pinpoint Weather Team watching a clusters of thunderstorms in the eastern Atlantic for possible tropical storm development….

Satellite images indicate that showers and thunderstorms associated
with an area of low pressure located about 1450 miles east of the
southern Windward Islands are currently limited.  This system
remains well organized, however, and it could develop into a
tropical depression later today or tomorrow while it moves westward
or west-northwestward near 15 mph.
     * Formation chance through 48 hours…high…70 percent.
     * Formation chance through 5 days…high…80 percent.

Nice Stretch of Weather

July 29th, 2014 at 1:10 pm by under General Talk, Tony's Pinpoint Weather Blog

After a humid and showery stretch, we will have a nice stretch of weather the rest of the week.

A cold front ushered in much less humid air into Southern New England this morning. The dew points dropped from 71 Monday afternoon to 58 this afternoon.  The dew point is a measurement of the amount of moisture in the atmosphere.  The higher the dew point, the stickier it feels.

Fcst_Map3_650x366

That cold front will stall offshore and hang out there for the balance of the week (and may play a role in our weekend).  An area of low pressure will ride along the front Wednesday and may bring extra clouds to Southeast Massachusetts.  We’ll enjoy more nice weather for Wednesday with sunshine and continued comfortable dew points.

Severe Thunderstorm Watch Until 8PM For “Parts” Of New England

July 28th, 2014 at 3:57 pm by under General Talk, Tony's Pinpoint Weather Blog

Good Afternoon from chief Meteorologist Tony Petrarca…

Strong to severe thunderstorms are developing over western Massachusetts and Connecticut. A few of these may impact areas from Providence points north and west thru 8pm. Storms looked to be localized so not all areas will see one. Some have potential to produce damaging winds and hail. Stay tuned for updates starting live at 5pm on channel 12 Eyewitness News.  We will have a live report from Revere, Massachusetts where a tornado touched down this morning with widespread damage.

Sunshine is a Double-Edged Sword

July 28th, 2014 at 1:07 pm by under General Talk, Tony's Pinpoint Weather Blog

It’s nice to have the sun this afternoon, but it really is a double-edged sword.  The sunshine will go to work and help de-stabilize the atmosphere in Southern New England.  This will help any storms that do develop to intensify and maintain their strength.  The satellite photo below shows many breaks in the cloud cover over our area.

vis_mon

Detailed 7 Day Discussion » Current Conditions » Radar » Severe Weather » Closings » Signup for Alerts & Closings »

Hurricane Tracker » Storm Ready Resource Guide » Severe Weather » Ocean »

The high-resolution computer models we use are showing a line of showers and thunderstorms moving out of western New England and into our area during the early evening.  This is the HRRR computer model for 6pm this evening.

hrrr_1

Until then, individual storm cells could continue to pop up through the afternoon in our area.  Any storms, whether they are moving through this afternoon or evening, could be strong to severe.  The atmosphere is ripe for these storms to produce very heavy rain, frequent lightning, large hail and damaging wind gusts.  The threat of an isolated tornado remains with us into the evening.  We’ve already had two confirmed tornadoes in Southern New England during the past two days, and the environment remains favorable for a quick twister to spin up.

We encourage you to remain weather aware through the day.  The good news is…the rest of the week looks delightful.

Confirmed Tornado in Revere

July 28th, 2014 at 12:06 pm by under General Talk, Tony's Pinpoint Weather Blog

Between 8 and 10am this morning a strong thunderstorm moved out of Northern Rhode Island and to the North Shore of Boston.  Revere was hit hard by what is now a confirmed tornado.  Live Pinpoint Doppler 12 Radar was tracking the storm as it moved from near Woonsocket to Revere this morning.  The storm was not severe as it moved through Rhode Island, but was developing a mesocycolone (a rotation within the storm cloud).

From the report:

“A TORNADO HAS BEEN CONFIRMED TO HAVE OCCURRED IN REVERE MASSACHUSETTS THIS MORNING. THE DAMAGE ASSESSMENT IS STILL ONGOING TO DETERMINE ADDITIONAL DETAILS SUCH AS THE MAXIMUM TORNADO INTENSITY…ALONG WITH THE LENGTH AND WIDTH OF THE DAMAGE PATH.”

Amazingly, there were no deaths reported to the Revere or Massachusetts State Police, but a baby was hurt by glass after a tree fell on a car.

Watching Things Closely This Afternoon

July 28th, 2014 at 11:49 am by under General Talk, Tony's Pinpoint Weather Blog

As of 11am, Live Pinpoint Doppler Radar was detecting showers and developing thunderstorms to our south, headed toward the coasts of RI and MA.

Radar_Loop_WEB_009

These storms are moving into an area favorable for development…decent instability, favorable wind shear and sunny skies.  In addition, low-level wind shear is favorable for the development of waterspouts and tornadoes.  While the possibility is low for a twister to develop, it’s there.  We encourage you to stay tuned through the afternoon….these storms can develop quickly.

Some Dry Time, but Strong T-Storms Still Possible

July 28th, 2014 at 5:06 am by under Tony's Pinpoint Weather Blog

Updated at 9:30 AM:

We are currently in a lull as the downpours from this morning have moved up to our north.  However, if we can sneak in a little sun today…a few more showers and thunderstorms could fire up.  So while there is plenty of dry time, we can’t completely rule out a severe threat.

REST OF MORNING: Plenty of dry time with a little hazy sun possible.  There will be a chance of an isolated shower or strong thunderstorm.

FLASH FLOODING THREAT: Low

WIND DAMAGE THREAT: Low

 

AFTERNOON: Some breaks of sun are possible, but this could actually fire up a few additional showers and thunderstorms.

FLASH FLOODING THREAT: Low

WIND DAMAGE THREAT: Low to Moderate

 

Summary: Even though it won’t be raining the entire day, we need to be on alert for the potential of showers and thunderstorms for the entire day.  There is a SLIGHT risk of an isolated tornado.

Stay tuned and we will keep you updated! -Pete Mangione

Multiple computer models indicate this area of showers and thunderstorms will move into New England and expand in areal coverage as it does so.

Storm has Weakened Significantly.

July 27th, 2014 at 8:55 pm by under General Talk, Tony's Pinpoint Weather Blog

As of 8:45pm, that big storm in Connecticut has weakened significantly.  Just a few showers remain in along the CT/RI border.

This storm was once a towering supercell.  What it looks like now is a sharp contrast between what it looked like at around 5pm.  Here’s a 3 Dimensional look at the storm while it was over Western Massachusetts.  It was a well developed thunderstorm standing up more than 30,000 feet high in the atmosphere.

Tracking What Was Once a Severe Storm

July 27th, 2014 at 8:27 pm by under General Talk, Tony's Pinpoint Weather Blog

Live Pinpoint Doppler Radar was tracking a nasty thunderstorm that moved through northern Connecticut.  It had mesocyclone (rotation) in it and was producing large hail alond with damaging wind gusts.  Trees and power lines were knocked down by this storm.

This storm has weakened significantly, but some gusty winds and downpours are still possible in western RI during the next 30minutes.

Funnel Cloud & Possible Tornado Reported

July 27th, 2014 at 4:38 pm by under General Talk, Tony's Pinpoint Weather Blog

4:46pm Update: The National Weather Service in NY has confirmed that a weak EF0 touched down in Wolcott, CT. 

———————————–

As I mentioned in last  night’s blog post, there was the chance for isolated tornado  today.  The biggest threat was in western New England.  Indeed, we saw funnel clouds and a possible tornado today.  Here’s the National Weather Service report regarding a funnel cloud spotted over Springfield, MA which moved to Ludlow, MA.

In Wolcott, CT a storm chaser caught up with a funnel cloud and captured video of the cloud making contact with the ground as a weak tornado.  He reported a ‘tell-tale roar once the funnel reached the ground.  Here’s a picture of this reported twister and some of the damage near Wolcott High School.  These are from Twitter user @stormtrooperjay

Severe Threat Diminishing

July 27th, 2014 at 3:21 pm by under General Talk, Tony's Pinpoint Weather Blog

As of 3pm, we have only a few downpours in RI and nearby MA….mainly over southeast RI.  They are moving eastward into Southeast Massachusetts.

Storm_Radar_650x366

Looking upstream over Connecticut and New York State we are seeing significant clearing in response to dry air settling over that area.  While the sunshine could spark an isolated shower or thunderstorm into the early evening, the severe threat is diminishing.

A Few Strong Storms Possible Today, Better Chance Monday

July 27th, 2014 at 8:14 am by under General Talk, Tony's Pinpoint Weather Blog

Updated at 2:00 PM

If we get a little sun late this afternoon and early evening, that would be our best shot to get some strong thunderstorms.  I would say the chance of those storms turning severe is low, but it is still a possibility.    After that, the next decent chance of severe weather would be overnight into Monday morning.   Please read below for more information.

 

DGraphiBlgggggg

Here is a breakdown of the severe storm threat:

Now to 8PM: While there will be plenty of dry time during this period, there is a slight chance of severe storms (especially if we can sneak in some sun to heat up the atmosphere).   Inland areas have the best chance (even though it’s a small chance) of getting flash flooding and wind damage, the coast has as a much smaller chance.

8PM to 12AM: The storm threat will still be there, but there will likely be plenty of lulls in the action.

12AM Monday to Monday Noon: The chance of some strong thunderstorms increases, with flash flooding being the biggest threat.

Please stay tuned through out the afternoon, we will continue to update this blog.

Keep a Close Eye on the Weather Sun/Mon

July 26th, 2014 at 11:01 pm by under General Talk, Tony's Pinpoint Weather Blog

During the next two days we will have several chances for showers and thunderstorms.  Some of the storms could be strong, too.

The Storm Prediction Center has put Southern New England under an area where there is a slight risk of severe weather on Sunday.

day2otlk_1730

The exact timing of these storms is difficult to pinpoint, but there are three main time periods for us:

  • Sunday morning/early afternoon
  • Sunday late afternoon/early evening
  • Monday morning

Round 1: Our first bout of storms comes Sunday morning/early afternoon.  The jet stream will dip down into a favorable position for air to rise over Southern New England.   The jet stream position, along with unstable air in place will allow storms to develop on Sunday morning over New York state and western New England.  These storms will move into RI and nearby MA after 9am and leave by early early afternoon.   The main impacts will be torrential rain, frequent lightning and possibly damaging wind gusts.

Smoky Skies in Southern New England

July 25th, 2014 at 7:54 pm by under General Talk, Tony's Pinpoint Weather Blog

Typically with a wind flow like we had today, we should have very blue skies.  Instead, the skies were pretty hazy.   That haze was from forest fires in northwest Canada!

SKYCAM2_650x366

Above is a picture from our Hurricane Barrier Cam in Providence.   You can see the haze in the sky, but you can also tell it was sunny this evening.

Satellite photos from space clearly show the path of the smoke from Canada into Southern New England.   Notice the dull gray blob over all of New England.  You can trace that smoke back up into central Canada.

Smoke_650x366

The flow of the jet stream (a river of fast moving winds high above in the atmosphere) is from the Arctic Circle directly into Southern New England.

Now check out this picture from NASA.  This is a high resolution satellite picture of Canada and the northern United States.   You can clearly see the flow of the smoke from the fires in northwest Canada into the Northeast United States.

The smoke does not bring any hazards to Southern New England.  I could smell the smoke while outside, but the concentration of smoke particles is not high enough at this time.  There have been instances when smoke plumes from distant fires did cause health concerns for us.  This does not appear to be one of those times; nonetheless, we are monitoring this closely.   If you have a respiratory illness where smoke could bother you, leave your windows shut and turn on the air conditioning.

Also, the added smoke in the sky will cause the sunsets to be more colorful.  The skies usually take on a more reddish color with smoke in them.  So, get your cameras ready!
