A cold front moved across the Pioneer Valley today and will sag to the south of New England tonight. Low pressure moves along the frontal boundary and passes well to the south of us later tonight and early Monday. High pressure takes over by Tuesday and settles in for Wednesday and Thursday as well. An ocean storm may impact the area Friday night into the start of next weekend.
I know the calendar says March but Mother Nature could care less. Although this next storm system will essentially be a miss to our south we are not going to avoid the continued cold temperatures all this week. For that matter we can expect some very cold air during the mid week period.
Considerable cloudiness with a chance of snow showers are most likely the only effects from the storm system passing well to our south tonight and early Monday morning. As the storm pulls away skies clear as another chunk of very cold air settles in overhead Monday night. The cold remains with us through the week with a slight moderation Friday before the coastal low approaches.
Temperatures are going to run 15 to near 20 degrees below normal Monday through Thursday. Overnight temperatures are expected to approach zero Monday night and again Wednesday night.
An upper level disturbance keeps a lot of clouds around Tuesday night through Wednesday night with just a chance of an isolated flurry or snow shower as the arctic air remains entrenched throughout the region.
By Friday clouds will be on the increase as the coastal storm begins to take shape in the Gulf of Mexico and off the US Southeast coast. Precipitation may break out Friday night, most likely as snow.
