NH1 Chief Meteorologist
National Weather Service Text Product Display The Country Lives On! On Wednesday...the surface cold front will be situated along the coastal plain and should retreat offshore along with the bulk of any scattered light shower activity during the afternoon. Breaks of sun will be possible across the interior during the afternoon. Highs will range from the 40s in the Connecticut valley northward through the mountains...with lower and middle 50s elsewhere. Seas will still be running 4-6 feet for our coastal waters thanks to an ocean storm hundreds of miles off the coastline.

For Wednesday night...skies will become mostly clear as a ridge of high pressure noses into the region. Lows will range from the mid 20s to lower 30s by dawn on Thursday. Some weak ridging will build in with partly to mostly skies and highs low-mid 40s in the north, to Lwr 50s on the coast, which is just a touch above normal. Light west winds. Temperatures will remain seasonal to end the week. A fairly deep trough moves quickly through Friday and Friday night with another cold front. Partly sunny skies and a gusty NW wind in the afternoon Friday. Gusty NW winds will result in a brief blast of below normal temps for one chilly day on Saturday as another trough digs in a provides a significant blast of cold air in this early cold season. The Colder air spill in from NW behind the Fri night and Saturday with the settling of cold air across the region continuing into Saturday afternoon, and this will keep upslope clouds in the mountains, with partly sunny skies near the coast.
Wind should diminish enough to make for a cold Saturday night with lows in the 20s across most of the region. The jetstream flowflattens out a bit Sun and and Mon, followed by a gradually moderating airmass into the start of next week. Look for temps to run slightly on the warm side through the middle of next week.
Moral of the story is any cold shot will be brief and temporary. Canada has a real lack of deep cold air in place. The heart of the cold is currently on the other side of the globe...but it will do a U-Turn eventually and return to the North American pattern just in time for winter. This December into January could be quite received quite a prolonged cold blast of air and be the main batch of cold for the winter, when ever that cold arrives.
