BOSTON (CBS) – This December is shaping up to be one of the coldest, snowiest and stormiest in recent years! We started with a bang this past weekend and the next event is already on its heels, coming in late Monday night. This one will be much different for many reasons but most importantly, the track will be much farther west, introducing milder air and more rain than wintry precipitation.
There will still be some snow and ice Tuesday morning and therefore some hazardous travel in spots.
TIMING AND PRECIPITATION:
Areas of snow, sleet and freezing rain will develop (mainly north and west of 495) during the pre-dawn hours Tuesday.
Slippery travel is likely in northern Worcester county, most of western Massachusetts and a good portion of Southern New Hampshire (away from the Coastline) during Tuesday morning’s commute.
Temperatures will slowly rise above freezing in these locations through the morning and by midday nearly all of southern New England will be just plain rain.
Areas of rain (a few heavy) will persist in the afternoon on Tuesday, there may even be a rumble of thunder in southeastern MA. The rain will taper off between 3-6pm.
Nada- Eastern MA
Coating to an inch- areas north and west of 495 in Middlesex and Worcester counties and also in extreme Southern New Hampshire from Nashua to Manchester.
1-2”- Extreme northern Worcester country (elevation) and into southwest New Hampshire.
2-5”- Berkshires and lower lying areas in Vermont, New Hampshire and Maine
5-10”+ Green and White Mountains, most ski areas of northern New England!
WIND AND COASTLINE:
No coastal impacts are expected.
The wind may gust to 40 mph Tuesday afternoon out of the south-southeast, strong enough to result in a few isolated pockets of damage.
BLAST OF COLD:
Behind this disturbance, harsh cold moves in Wednesday and lasts through the end of the week.
High temperatures will only be in the 20s with overnight lows dropping into the teens Wednesday night and Thursday night.
On top of that, the wind will gust 40-50 mph out of the west, creating wind chill values in the single digits and teens, easily our coldest shot of air yet!
Keeping our eyes on Friday/Saturday timeframe as another quick moving disturbance will be zipping out of Canada and off to our south. We may be just fringed by some snow, but a closer track to our Coastline could mean another significant snow accumulation…stay tuned!
