What's Up, Winter

So far March has been a bit up and down when it comes to temperatures.  Last year the temperature spiked to 77 in Boston on this date while in 2005 the max temp stalled at 24.  In 2007 the low temperature was 5.  Today will be near normal temperature-wise but gusty westerly winds will make it feel colder than it actually is.  The NWS has issued a *Wind Advisory* until 4 PM for sustained winds 20-30 MPH with gusts 40-50 MPH.
NWS AM Headlines
You may be drawn to the *Winter Storm Warning* on the Cape/Islands or the *Winter Weather Advisory* in CT, S Worcester, and Norfolk counties There is a *Winter Storm Watch* in SE MA and RI..  Skies will be mostly sunny today with wind chills in the upper 20's/low 30's.  When the wind is calm it will feel nice because the March sun angle gets higher and higher every day.
WPC Surface Fronts/Precipitation Thursday 7 PM
A front will pass through New England today which will help enhance the wind threat.  This boundary will stall across the Mid-Atlantic, south of Long Island.  Low pressure will ride along the boundary developing a little bit as it reaches the Atlantic.  Snow will break out along the South Coast after 2 AM.  It will reach Southern Worcester County and most regions south of the Pike around 530-6 AM.

It snows steadily until early afternoon.  Snow is gone from the Worcester area around 2 PM, Boston 3 PM, and the Cape and Islands by 5 PM.    Total snow looks like 1-3" from Springfield to Worcester to Boston down to the South MA/RI/CT border.  3-6" in CT, RI and SE MA down to about Middleboro and Taunton and 6-10" across S coastal RI and the Cape and Islands.
NWS Total Snowfall Forecast Through Saturday 7 AM (image Weatherbell)
This whole system has been trending north and higher snow totals so I will issue a PM update tonight.  Temperatures tomorrow are in the low 30's with winds shifting from the Northeast to Northwest at 5-10 MPH.  An Arctic cold front will cross the region tomorrow night.  Another round of snow squalls will be possible.
WPC Surface Fronts/Precipitation Friday 7 PM 
This incoming air mass will deliver mid-winter cold, much like last weekend.  We may again be in record-breaking territory.  Here is the origin of that air mass. 
Another snow threat is developing for Tuesday of next week, but we have plenty of time to watch that one.
