We’re not done with winter weather yet.
The National Weather Service forecasted a low pressure system in Massachusetts, bringing with it snow and a wintry mix that will impact the region Friday night into Saturday.
So far, the meteorologists are predicting the more significant weather impacts will be seen north of I-90, where some areas could see between 8 and 12 inches of accumulation, while southern and coastal areas of the state are likely to see just a coating, if that.
The service has issued a Winter Storm Warning for northern parts of Massachusetts, which is in effect from 7 p.m. Friday through 7 p.m. Saturday.
“The challenge remains temperatures, and their impact on precipitation type,” the service said Friday morning. “Snowfall is most likely tonight, with increasingly less favorable conditions during the day Saturday.”
The forecasters said they are expecting snow to kick off the precipitation on Friday night, with it transitioning to a mix of snow and sleet after midnight south of the Mass. Pike.
“Warmer air continues to stream north, leading to a wintry mix even across the higher terrain Saturday, with rain expected towards the coasts,” the service said. “The best chance for all snow will be across far northern MA, along and north of the Route 2 corridor.”
Below, what local forecasters are saying so far about the timing and impacts of the wintry mix:
Little to no accumulations from this point forward for most areas south of I-90. Several more inches of snow are expected north of I-90, especially along and north of route 2. pic.twitter.com/nqyMgWmejY

Winter storm watch upgraded to winter storm warning generally north of I-90 with the exception of northeastern MA east of I-95 where an advisory is in effect. Advisory also in effect for areas south of I90 and west of I495 away from the coast. Heaviest snowfall will be overnight. pic.twitter.com/JNgtfrQFZ6

The worst travel tomorrow morning will be where snow/sleet lingers the longest. (Pre-dawn, roads will be slick too near the coast) pic.twitter.com/vyrVZaRSVu

East winds gust tomorrow morning 40-50mph at the coast. Strongest Southeast Mass, few gusts to 55mph there. pic.twitter.com/uMsdz92ZMS

Heaviest snow/sleet amounts will be across northern Mass. Even across Boston/MetroWest, those lower amounts are loaded with water content thanks to sleet and some drops mixed in. A lot of weight to push around. pic.twitter.com/EhinQgwW5U

Winter's mess to drop plenty of snow, ice and rain. Coastal wind an issue too. pic.twitter.com/uCCh32M10v

I doubt much of Southern New England except the deep interior will see much accumulation after about 9am thanks to sun strength equivalent to October, but the burst until then accumulates & from north-Central MA northward continues to add up a bit longer, esp. Northern NewEng. pic.twitter.com/N88A7cVZ25

Precipitation will slowly but surely get lighter as Saturday wears on, and after mid-morning it's hard to add much accumulation where temps are above melting which is most of Southern half of NewEng. Therefore, widespread outages not anticipated but isolated due to wind speed. pic.twitter.com/zlcVb24FzR

While a First Alert for impact of wintry mix is up for a lot of New England from our @necn and @nbc10boston #FirstAlert Team, by far the highest impact will be coastal Maine, where Portland will likely see near-blizzard conditions Sat AM and Midcoast may actually attain them. pic.twitter.com/N9gumpEFAm

WHEN DOES SNOW ARRIVE…
— Cindy Fitzgibbon (@Met_CindyFitz) March 3, 2023
9pm to midnight from west to east across our area. Early evening plans should be ok #WCVB pic.twitter.com/LwHZS7Z8l1
MESSY MIX…
— Cindy Fitzgibbon (@Met_CindyFitz) March 3, 2023
Snow moves in tonight but will change to rain in SE MA by sunrise Saturday as the wind comes in off the ocean. Warmer air aloft will change snow to sleet near the pike and possibly the North Shore keeping snow totals down. Heavy, wet snow to the N&W #WCVB pic.twitter.com/30jjZ5C7D1
WIND ADVISORY…
— Cindy Fitzgibbon (@Met_CindyFitz) March 3, 2023
Along the coast Saturday morning thru early afternoon for ENE wind gusts of 50-55mph. Winds will turn more northerly in the afternoon #WCVB pic.twitter.com/ztfg1m716P
FORECAST CHALLENGES…
— Cindy Fitzgibbon (@Met_CindyFitz) March 3, 2023
Marginal temps mean a tough snow forecast.
-How far north will warm air aloft come to bring sleet
-East winds bring in warmer ocean air at low levels
-After 8am Saturday snow will battle stronger March sun angle and be tougher to accumulate#WCVB pic.twitter.com/lYkSlyamKo
SNOW FORECAST

Heaviest snow the farther N&W you go where 4-8" of heavy, wet snow could accumulate.
2-4" near the pike and 128 where sleet will mix in (water logged and tough to move)
Sloppy coating to 2" immediate coast, Boston and areas south where it changes to rain #WCVB pic.twitter.com/eLVs5EiQFz
