Light to Moderate Snow Event Tomorrow
(I am going to take this one storm at a time. It appears a major get the bread and milk winter storm is on its way Tuesday-Wednesday next week. I'll post on that event tomorrow. At 120 hours out there is still plenty of time to monitor.) - Zack Green
A wave of low pressure riding along a frontal boundary south of New England will develop a snow shield as it passes the region Friday AM. Snow will begin before dawn and will taper off in the early afternoon. Generally speaking, a coating to an inch is possible along and north the MA Pike while 1-3" south of the Pike in Hampden, Worcester, and Norfolk counties. 4-8" will fall in RI and SE MA with perhaps locally higher amounts on the Cape. Potentially historic cold arrives this weekend.
The NWS has issued a *Winter Storm Warning* in pink and a *Winter Weather Advisory* in light purple.

As an aside the strength of the high pressure dropping into the States is impressive. Snow will begin to stick to grassy surfaces around 5-6 AM. Here is the future radar for 5 AM tomorrow.

The snow gradient is tight tomorrow but radar trends in the morning will tell us whether or not the snow shield is further north (south) than anticipated.
