Yesterday was a nice respite from the worst of the deep freeze as temperatures made above zero for most, and even got to double digit readings for some parts of the coast. Today, a storm developing well to our southeast will bring a reinforcing shot of bitter cold, and we’ll be headed back to the brutally low temperatures of a few days ago. Highs will range from -10 in the north and mountains to +5 along the coast. Most of the area will remain sunny and free of precipitation today, however upsloping NW winds will keep clouds and a few flurries in the mix for the mountains.
This map from the Swiss Super HD model shows wind chills bordering on dangerous this afternoon. Ignore the large swath of null values downwind of Mt. Washington where the model thinks that winds are calm or nearly calm due to the influence of the mountain. Wind chills in the Sebago region will be just as brutal as anywhere else, dropping below -20 for much of the day today.
Bundle up if your NYE plans take you outside tonight, even for a short period of time!
