Two Rounds of Snow On The Way To SNE

A quick hitting storm will bring plowable snow to Southern New England on Saturday.  A second storm will bring even more significant snow  overnight Sunday into Monday morning.  Let's get into it.

Headlines
A *Winter Weather Advisory* is in effect from 1 AM Saturday until 7 PM Saturday.  The heaviest snow will fall in the morning, with a break mid to late afternoon.  A second batch of light to moderate snow will move through Saturday evening. 

NWS Early PM Headlines 

Saturday Storm
There will be no issues this evening.  Temperatures will be in the mid to upper 20's.  Temps in Northern RI, Central, and Northeast MA (including the city of Boston) will be in the mid to upper 20's  tomorrow morning.  From Providence to Plymouth south and east, temperatures will be in the low 30's.  This means that the snow will be a bit fluffier the further north and inland you go, and wetter and heavier the further south and east you get.

WPC Surface Fronts/Precipitation Friday 7 PM, Saturday 1 AM, 7 AM 

Snow will reach Southern Worcester County after 4 AM.   The snowfall intensity will pick up between 7 AM 12 PM.  Snow showers will linger Saturday afternoon in Central MA, while steady snow will continue in SE MA and RI until the mid to late afternoon.

Snow accumulation will be highest south and east of Hartford, Worcester, and Lowell.  The jackpot will likely be somewhere from Providence to Plymouth.  In the Blackstone Valley, expect 3-5" of snow.

Sunday
Sunday will actually be pretty nice, although there will be snow on all the sidewalks and lots of puddles from some of that snow melting.  The March sun angle is quite strong so even with temps "only" in the upper 30's, it will still feel comfortable.  It is all a tease, as the morning sun will give way to increasing high clouds as the next storm approaches. 

Sunday Night-Monday Storm
This storm will start as snow for everyone.  Snow will begin after 7 PM, with snowfall rates increasing after midnight.

The EURO model drops 4-8" of snow before changing to rain inside 495 and south of the Mass Pike, including the Blackstone Valley.  Other models have more snow.  There is still plenty of time to evaluate the precipitation type for this one.  It will definitely begin as all snow and even if it does turn to rain, the morning commute is going to be a mess.  The good news is, this system will be gone by lunchtime.  

Opening bids for snowfall accumulation is 5-10" in the Blackstone Valley, with highest totals outside 495 and north of the Pike.  

More to come this weekend.
