Several Inches of Snow Today

A quick moving storm will drop several inches of snow across Southern New England today.  Most of the precip will fall early this afternoon and this will impact the PM commute in Eastern MA.  The National Weather Service in Taunton has issued a Winter Storm Warning for parts of the region (in pink) and a Winter Weather Advisory (in blue) for others.  The Cape, Islands, and SE MA are not included in the headlines as they will see mostly rain.
Overview A storm in the Great Lakes will move towards New England today and will strengthen south of New England.  Here is the surface chart The regional radar shows some precipitation already streaming into Western New England.  A lot of this is not reaching the ground.  Expect snow to begin accumulating around 7 am in W CT/MA and by 9 in Boston. It is cold in New England this AM.  SW CT and the Outer Cape are the only ones in the 20's.  This means snow will stick immediately and travel will become difficult. As the low track towards New Engla…

Another Winter Storm Saturday Night

My neighbor accused me of enjoying all these snowstorms.  I enjoyed all the fluff bombs in January but I HATED the cement I shoveled for the last 36 hours.  Whether I like it, whether you hate, whether you are indifferent is irrelevant to mother nature.  Another snowstorm is on the way tomorrow night. Now if you live outside of 495 it may track far enough offshore so that only 1-3" of snow falls.  The Cape and Southeast MA will not be so lucky.   The details...

General Overview
Here is the 4 PM surface chart.  The low is located along the IL/IN/KY border
The upper level support is impressive.  Note yesterdays storm departing through Atlantic Canada The Great Lakes Regional radar is impressive this afternoon The water vapor satellite imagery is also impressive  This storm is going to explode when it reaches the coast.
Timing, Impacts, Accumulation Light rain/snow will move across Southern New England between 1-4 PM tomorrow.  By 7 PM the storm will be located south of Cape Cod and w…

Another Batch of Precipitation Tonight

The first phase of this winter storm is over.  Nearly a foot of snow fell in Central and Western MA, Southern New Hampshire, and Eastern Connecticut.  The second phase is the lull in precipitation region wide.  The third and final phase will occur from 10-7 am.  This will occur as the storm center moves over SE MA and moves into the Gulf of Maine.  
Discussion Here are the preliminary snow totals Winds gusted 40-55 MPH in SE MA.   Winds will continue to gust close to 40 MPH especially in heavier precipitation.  Here is the regional radar as of 828 PM Here is the water vapor image with surface fronts from 815 PM This is a textbook satellite image.  This is driven by a strong upper level low And also by a strong jet stream By 1 AM the low should be near the SE MA coast or over it High res guidance and radar trends suggest another 0.5 inch of precipitation for most of New England and perhaps some big time snowfall accumulations in the Berkshires.  This is likely rain in Eastern MA.  In Wo…

Pre Storm Observations

Good Morning.  Light snow is arriving in Southern New England as of 530 am.  Heavy snow, rain, sleet, ice, and wind will impact the region through early Friday morning.  Winter Storm Warnings have been extended into Essex and Suffolk Counties.
Wind Advisories exist for the east coast of MA from the Cape up to Gloucester.  
Overview First things first the current temps are in the 20's in SE MA, RI, and CT.  Temps are in the teens for the rest of MA and single digits in Central/Northern New England High pressure has scooted east into the Atlantic but as you can see there is impressive cold that remains.  Our storm is deepening already off the Carolina coast.  Here is the surface chart Here is an awesome satellite shot of the East Coast.  This is the Water Vapor satellite  Here is the radar this morning.  DC has 6" of snow already and it is still snowing there.  They will eventually change over to rain It will not take long for the snow to become steady and it will accumulate rap…

Forecast Update

A strong winter storm will impact many in the Eastern US over the next 2-3 days.  The storm is expected to track over the Cape which means many South of the pike and inside of 495 will change to rain for a period on Thursday.  Heavy wet snow will fall before any changeover and this storm will pack strong winds.  
General Overview The National Weather Service in Taunton has issued a Winter Storm Watch for inland areas in blue Temperatures remain cold across the Eastern 2/3 of the country Here is the surface chart.  High pressure in the Great Lakes is allowing cold air to pour into the South.  This sets the stage for a major Snow/Ice event in the South tonight/tomorrow.  This situation is no joke for our friends down there.  Ice can be paralyzing for any community, no matter how use to winter.
Here is the Southern Mississippi Valley radar  There is plenty of juice in this system.  
Short Term Forecast Not to be overlooked is another bitterly cold night ahead.  Its already down to the tee…

Another Winter Storm Thursday

Are you sick of winter yet?  It has been a remarkable winter so far for the Eastern 2/3 of the United States.   Another winter storm will impact Southern New England on Thursday.

A Polar Front has reached the Gulf Coast as a large dome of high pressure built up in the middle of the country.  Here is the 1 PM Surface Analysis
Here is the US temperature map as of 4 PM The Jet Stream splits into a Northern and Southern stream in the west.  One stream is in Southern California through Arizona and New Mexico while the other enters the US in Washington. Embedded within both streams are pieces of upper level energy.  These show up nicely on the 500 mb chart (I've circled the two pieces to watch) Both pieces also show up on the water vapor satellite  The Southern piece of energy will slide east through Arizona, New Mexico, and Texas towards the Gulf Coast while the Northern piece slides southeast through Montana, South Dakota, Nebraska, and Missouri.  The Southern piece will deli…
