The cold has eased considerably across New England on Wednesday, but while the thermometer will measure high temperatures near 40 degrees south and 30 degrees north Wednesday afternoon, the increasing southwest wind carrying this milder air into New England has the ironic effect of creating a wind chill to slightly offset with wind chill values never breaking above the 20s south and teens north.
Gusts from the southwest have already surpassed 40 mph in the Champlain Valley of Vermont and likely will at the minimum go beyond 30 mph for many communities by day’s end.
Clouds will keep variable as milder air moves in aloft and collides with our departing cold, and this is likely to be the case overnight Wednesday night into Thursday in addition, though precipitation will keep limited to some flurries at the border with Canada on Wednesday afternoon and some distributed snow showers in northern New England on Thursday.
With much less wind expected Thursday, high temperatures around 40 south and in the 30s north will truly feel much better in the absence of wind chill. All the while, the jet stream pattern across the country – the fast river of air, high in the sky, that steers disturbances and storm systems – will be aligning in a pattern that favors storminess in the eastern half of the nation.
Where will it snow on Friday?
The first developing strong storm will find its footing Friday over the Gulf Stream off the Eastern Seaboard and move north. With a razor-sharp western edge to its precipitation protect, this storm is doubtful to deliver much more than clouds to most of New England, but we’re watching the track carefully for communities within about 30 miles of the coastline in eastern New England and especially Cape Cod and eastern Maine closest to the storm’s track and most likely of anyone to see some rain to snow or simply snow that may build up Friday.
Although the most likely forecast is a coating to an inch or two near the coast and onto the Cape, the increase in precipitation is meaningful with this storm as you get closer to its center, so a slight deviation west would average a bigger deal while a nudge east would put nearly all of us in the clear.
The Friday storm moves east Friday night, but does an effective job at carrying cold, arctic air back into New England on Friday night by the weekend, with Saturday high temperatures likely only in the teens south and single digits north with a sharp breeze, then only about 10 degrees less cold Sunday.
Meanwhile, the busy jet stream pattern will already be brewing the next storm – energy dropping southeast from Canada will paint a stripe of accumulating snow from the Upper Midwest by the Tennessee River Valley, then combine with a southern disturbance chock complete of Gulf of Mexico moisture to drop snow over Georgia, the Carolinas and march a strengthening, moisture-loaded storm up the East Coast on Sunday night into Monday.
How much snow will we get on Monday?
Our team has issued a First Alert for Monday owing to the exceptional amount of moisture and the preceding cold air that seems likely to crank out at the minimum some accumulating snow, already if a rain/snow line were to end up over southern New England Monday, which is nevertheless to be determined hinging on storm track.
in spite of, whomever is northwest of the storm track is likely to pick up plenty of snow. Winter air remains by the end of the 10-day forecast.
