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.

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.

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.

Storm_Radar3_650x366

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.

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.

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.

-Pete Mangione

 


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.

upaCNTR_300

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.

nasa_smoke

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!

Forecast Change for the Better Today

July 24th, 2014 at 9:07 am by under General Talk

All week we’ve been talking about a cold front slowing down as it moved off the southern New England coast today… well, there’s some good news!  Instead of the front pestering us with lingering clouds and showers… it looks like it will move just far enough away for the dry air to win out.  That means a pretty nice Thursday.  It won’t be as hot or as humid with partly sunny skies.  There’s just a small chance of a brief shower, but most of us should stay dry through the day.  I hope you can get out and enjoy the day. temp 1


Tropical Depression #2 Has Formed

July 21st, 2014 at 4:56 pm by under General Talk, Tony's Pinpoint Weather Blog

It’s not too much of a surprise…Tropical Depression #2 has formed in the Deep Tropics.

TD2

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

The system has become better organized with thunderstorms organizing around the center of circulation.  TD #2 is expected to continue to move west-northwestward with minimal development.  The National Hurricane Center said that it will be moving over an area of unfavorable water temperatures in the next 2 days.  Also, drier air near the Caribbean Sea will also hinder its development.  Still, it’s a system to watch closely in the coming days.

Bertha in the Making?

July 21st, 2014 at 2:27 pm by under General Talk, Tony's Pinpoint Weather Blog

In the central Atlantic Ocean, there is an area of low pressure which could soon become the next tropical storm.  If sustained winds strengthen to at least 39mph, it would be named Bertha.  The National Hurricane Center in Miami said there is a 70% chance that this area becomes a tropical depression. Conditions are favorable for strengthening in the next couple of days.

Embedly Powered

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

 

It’s about 1250miles east of the Caribbean.  It’s days away from affecting any land, but it is certainly something to watch as it continues to move westward.

The visible satellite image shows a well defined circulation, and in my opinion, it is probably already a tropical depression and close to a tropical storm.  There are no plans for Hurricane Hunter aircraft to investigate this area (it’s still pretty far away).   Nonetheless, the National Hurricane Center is advising people in the eastern Caribbean to monitor the situation closely.

Flash Flood Warning in Effect Until 10:30am.

July 16th, 2014 at 7:59 am by under General Talk, Tony's Pinpoint Weather Blog

Flash Flood warning has been issued for parts of RI and SE MA for much of RI and into parts of Bristol County in MA.  A Flash flood warning means that flash flooding is occuring or imminent.  This line of strong thunderstorms has brought torrential rainfall with rates of 2-3″/hr.  Street and poor drainage flooding is likely along with some smaller stream flooding.  temp 1


Today’s the Day

July 16th, 2014 at 7:10 am by under General Talk, Tony's Pinpoint Weather Blog

Today’s the day that RI and southeastern MA will have the highest risk of showers and thunderstorms due to a slow-moving cold front.  It’s a front that’s been sparking nasty storms across New England since Sunday evening and today it will FINALLY move through southeastern New England and then eventually off-shore.  We’ve been able to dodge most of the storms over the last few days, but today I think our luck runs out.  Since the front is approaching RI and southeastern MA (and eventually moving over us), we have a high chance of seeing rounds of showers and thunderstorms through the day.  In fact, we’ve already been dealing with downpours for the morning commute.

The main concern today continues to be the potential for FLASH FLOODING.  The Flash Flood watch is in effect until 2pm.  Tropical downpours will be off and on through the day with rainfall rates of up to 1-2″ per hour possible.  That sort of deluge can cause typically prone spots to quickly flood, making travel difficult.  The threat of severe storms is a bit lower than the last few days, but we could certainly see some embedded stronger thunderstorms with frequent lightning and isolated damaging wind gusts.

 


Highest Risk For Severe Storms “Western” New England

July 15th, 2014 at 2:44 pm by under General Talk, Tony's Pinpoint Weather Blog

Good Afternoon From Chief Meteorologist Tony Petrarca..

As of 2:30pm, most of our area as been void of any strong to severe thunderstorms.  The highest risk still looks like central and western Massachusetts and Connecticut.  However a strong thunderstorm(s) cant be ruled out for rest of our area this evening  thru Wednesday, so stay tuned to future forecasts, tweets and blogs. Flash Flood Watch remains in effect in anticipation of heavier downpours tonight into Wednesday .

The Beat Goes On…

July 15th, 2014 at 8:59 am by under General Talk, Tony's Pinpoint Weather Blog

The same steamy air mass and slow moving cold front that brought some showers and thunderstorms to New England on Monday is still affecting our weather today.  And the risk for severe storms continues.  The storm prediction center is continuing to highlight western New England as the area most at risk of seeing storms with damaging winds and heavy rain develop.  The high-resolution RPM model is showing that area to be one to watch by early-mid afternoon.

temp1

RPM Model for 2pm Tuesday

There is even a slight chance of an isolated tornado spinning up in one of these thunderstorms today.  In southeastern New England, the risk of severe weather will be lower, but that doesn’t mean we can’t see some nasty storms later today.  Any storms that develop in western New England will need to be carefully monitored as they move east towards the RI border during the afternoon and evening.

Our area will see more widespread showers and embedded thunderstorms late tonight and Wednesday as the cold front finally moves through southeastern New England.  We’re at risk of torrential downpours and gusty winds during Wednesday morning’s commute with localized street and poor drainage flooding potentially leading to a slow commute.   temp 2

The rain will taper off from west to east through the late afternoon and evening, with drier weather finally returning by Thursday.

Severe Storms Possible Today

July 14th, 2014 at 5:27 am by under General Talk, Tony's Pinpoint Weather Blog

Our area has been placed under a “slight” risk for severe storms today by the Storm Prediction Center out of Norman, OK.

Severe T'Storm Outlook

Severe T’Storm Outlook

temp3

Wind Damage Potential

As the Pinpoint Weather Team has been stating over the last few days… our atmosphere will be primed for strong to severe storms to pop-up over the next few days.   As for today… humidity will build and some peeks of hazy sun should allow for the atmosphere to become unstable… as a piece of energy in the upper-levels lifts through southern New England it will act as the focus for storms to begin developing through the afternoon.  Torrential downpours and damaging winds are the biggest concerns with these storms.

temp2

Tornado Risk

The Storm Prediction Center has also placed areas just to our southwest under a slight (2%) risk of a tornado.

Locally, the National Weather Service office in Taunton has issued a “FLASH FLOOD WATCH” for Connecticut and Western MA. These areas are most at risk of seeing rounds of thunderstorms that could contain very heavy rainfall leading to localized flash flooding.  Some storms could dump up to 3″+ of rain over the next few days.

temp 1

The risk of flash flooding will likely spread east into RI/SE MA, especially later Tuesday into early Wednesday.

Good Evening from chief meteorologist  Tony Petrarca

While it is still several days down the road, our computer guidance data continues to indicate the “potential”  for severe thunderstorms from Update New York into New England next Tuesday afternoon and evening. However, many “atmosheric parameters” need to come together for this to happen…bottom line, stay tuned.  This is still 3-4 days out which means it is to early to talk specifics….but our weather team just wanted to give you an early head up on this “potential”  Meanwhile this weekend looks beautiful so enjoy. Pete Mangione will have updates this weekend and I will be back on air Sunday Night with more information.

The National Weather Service storm survey team says it was a powerful microburst that caused the wind damage in the Boston suburb of Bedford around 5:45pm yesterday.  A severe thunderstorm hit the area during the evening rush hour, carving a path of damage across the center of Bedford that was 2.5 miles long, and a half mile wide, uprooting trees and power lines.  The storm survey team estimates winds were 90-100mph in the microburst, which leads to straight line wind damage.

The storm blew down and uprooted approximately 50-70 trees–most of them were healthy pine trees towering some 100ft high! Some of the trees landed on houses and caused significant damage.  Here are some pictures from storm spotters in Massachusetts yesterday.

Despite many images of what appeared to be a funnel cloud in the Medford and Malden areas around 6pm, there were no eyewitness reports of any tornadoes.

While the heat and humidity build this afternoon, an isolated strong to severe thunderstorm can’t be ruled out… though we don’t expect the activitiy to be as widespread as yesterday around Boston.  Here’s where the NOAA Storm Prediction Center is indicating the highest risk of severe storms will be–with damaging winds being the biggest threat.
