The upper level low continues to spin across northern New England into the Canadian Maritimes today. Gusty winds prevail across the area, with temperatures running several degrees below normal. Early cloudiness should give way to a generally partly cloudy sky. All this adds up to a cold and blustery day with the wind chills in the upper teens to around 20 degrees. These conditions do not change much overnight, although clouds should slowly clear out by morning.
Friday will be a quiet day as the winds finally begin to ease up and we enjoy a fair amount of sunshine as a ridge of high pressure settles over the area. Temperatures will rebound to near seasonal levels, climbing into the upper 30s for most areas. Late in the day the first signs of the weekend storm may begin to show on the southwest horizon as clouds start to filter into the area overnight.
For the third consecutive weekend we are talking about a winter storm. Not just another storm but the potential for another significant storm that brings many impacts to the region. As usual there will be several potential weather impacts such as heavy snow, gusty and possibly damaging winds, coastal flooding and rain on the coast. The coastal low will develop in the waters south of New England and move to a position near Cape Cod early Sunday. The storm track is always critical in these situations as to exactly where the rain/snow line sets up and who gets the heaviest bands of snow on the northwest side of the storm track.
Storm Details: As of this morning it appears precipitation overspreads the area by late Saturday as all snow inland and a wintry mix on the coast. Overnight, a wintry mix on the coast may change to all snow by morning as the intensity of the storm picks up and it snows hard inland. Snow continues into at least midday on Sunday, tapering off during the afternoon hours. A heavy wet snow is expected locally, unlike what we have had the previous storms when it was a fluffy snow. A combination of heavy wet snow and the likelihood of gusty winds may be enough to cause damage to trees and power lines, leading to the possibility of power outages. The Sunday morning high tide will need to be watched for the potential for coastal flooding as well.
A preliminary look at snowfall accumulations are 6 to 12 inches west of Route 128, tapering to 3 to 6 inches along the coast. Now, if it rains on the coast or stays a wintry mix for a longer period of time this will lessen the totals. Also, if the rain snow line moves further inland it would lower the totals between Routes128 and 495. There will probably be a sharp cutoff from heavy snow to much less snow. This will be refined as the weekend approaches.
