Forecast discussion: High pressure slowly worked its way south of New York this afternoon, keeping a low pressure system out in the ocean. Due to the low staying well south of us, the precipitation shield remained over the Cape and Islands. Nantucket did receive 4 inches of snow by this morning, with barely a flurry falling over Boston.
We felt the beginnings of an arctic cold front today, keeping our high temperatures well below freezing. However, as the winds shift to the southwest, warmer air will once again filter back over the state. For Saturday, we will see our temperatures climb into the middle 40’s. However, the winds will be strong, with some near gale force gusts at times. However, winds will diminish by Saturday evening. We will still feel the warm air on Sunday, before another arctic cold front moves through the Northeast U.S. by Sunday evening.
Winds will increase once again, due to a tighter pressure gradient between the high pressure system and a low pressure system moving through Canada. Temperatures will begin to fall during the Patriots game, and wind chills will make it feel colder. So, please dress warmly if you are heading to Foxboro on Sunday.
Unlike this weekend, the cold air will remain over us for most of the week. Temperatures during the day will slowly climb to the middle 20’s by Thursday. Also, I am still watching a possible ocean storm that will be developing Monday night into Tuesday. It appears the low will remain well south and east of Southern New England. So, we may still see some passing snow showers, with little snowfall. However, this could change, so I will continue to monitor the computer models. Also, there is the chance of another developing ocean storm on Friday. However, the computer models disagree on the intensity and location of the low’s center. For now, I will keep possible snow showers in the forecast for Friday, but my confidence at this time is very low.
