Winter Storm Warning Northern RI

March 18th, 2013 at 6:27 am by under General Talk, Tony's Pinpoint Weather Blog

Good Monday morning,

New data continues to flow into the Pinpoint Weather Center this morning, giving us growing confidence in a period of wintry weather from late this evening through tomorrow morning before changing to plain rain.

In fact, the National Weather Service this morning upgraded the Winter Storm Watch to a Winter Storm Warning for Northern RI, where our highest snowfall accumulations are expected—as much as 4-6″ of snow and sleet.  In addition, the Providence Metro area through Kent and South Counties, along with northern Bristol County, MA are now under a Winter Weather Advisory.  The Alerts are for 9pm this evening through 11am Tuesday.

We are most concerned about messy travel conditions for tomorrow morning’s commute.

TIMING:  Snow arrives between 8pm and 12am.

          Changing to Rain from south to north between 6am and 11am Tuesday

         Periods of Rain in the Afternoon will taper off most areas by 8pm

ACCUMULATIONS:  NW RI–4-6″

                                Central  RI to Northern Bristol Cty MA–2-4″

                                Coastal RI/MA–Coating to 2″

RAINFALL:  Additional 0.5″ to 1″ of  rain after the changeover

WINDS:  East winds 10-20mph with gusts to 35mph

COASTAL FLOODING:  Not an issue because tides will not be astronomically high.  We catch a break in this regard

RIVER FLOODING:  We’ll watch local rivers and streams, however, right now rainfall amounts are not expected to be heavy enough to cause flooding of our major rivers–Pawtuxet, Blackstone, Pawcatuck.
