A rush of cold, Canadian air will invade western Mass today, on a gusty westerly breeze. Temperatures will stay mainly in the 30s but wind chills will be stuck in the teens and 20s. We may catch a quick flurry this morning under a blend of sunshine and clouds.
The cold weather doesn't stick around long. After a chilly day tomorrow the mild air returns for all of next week! Tomorrow will be the pick of the weekend, with mostly sunny skies, lighter winds and temperatures a couple of degrees better than today.
The jet stream will lift into Canada as another ridge builds across the east. This will bring another surge of unseasonably mild air for Christmas week including the holiday. In fact, as Santa arrives temperatures may climb to near 60 degrees! We are watching a few chances for showers here and there during this coming week but nothing to organized. The best chance for some rain looks to be Wednesday into Thursday.
Unfortunately with the big warm-up, needless to say there will NOT be a white Christmas this time around. In fact, it will be a green Christmas. Since the ground has not yet frozen many lawns still are in good shape. The unusually mild pattern may stick around through the end of the year.
