The weather is shaping up to be quiet and very cold Christmas Eve and Day in Southern New England. A mild weather system will bring some rain Sunday and Monday. Highs will be in the 50s to low 60s Sunday, and 50s on Monday. Last-minute shoppers on Monday may have to deal with steady rain and temperatures in the 40s during the afternoon. It’s possible the rain ends as snow showers early Tuesday, but high pressure will build in Tuesday afternoon, leading to clearing skies.
The cold area of high pressure will move from Eastern Canada to over New England by Christmas Day. It will be breezy to windy and turning colder on Christmas Eve. Wind chills will be in the singled digits to teens by late in the evening. The temperature will tumble into the teens with single digit wind chills early on Christmas morning. There should be plenty of sunshine on Christmas, but it will be cold, with highs only in the 20s. The wind will relax during the afternoon, so the wind chill will no longer be an issue. The weather will stay fair through Wednesday evening.
