Metro Boston, north shore and western suburbs: Showers and widespread dense fog preceded the strong arctic front that moved through here during the early afternoon. Much colder air follows behind the front as the area slides into the deep freeze beginning tonight and lasting for a couple of days.
It was nice to get a break from the cold, no matter how short it lasted, but now winter quickly sets back in. The remainder of the week features below normal cold through Thursday morning with some moderation towards late week. Morning temperatures climbed into the low and mid 50s Monday before the arrival of the front. The mercury slid through the 40s during the afternoon once the colder air began to overspread the area.
Tonight, the arctic air continues to work in and temperatures are going to plummet. There will be a quick refreeze of puddles and untreated roads and walkways. We are not going to see the serious and dangerous cold that is attacking the Plains and Midwest but it gets uncomfortably cold here. By morning temperatures will have collapsed to near 10 degrees. Just as important will be the gusty winds behind the cold front, increasing to 30 to 35 mph in gusts, lowering wind chills to 10 below zero by morning, a far cry from what we experienced this morning. There is a slight chance of a passing flurry or snow shower tonight as a disturbance up above moves through.
Tuesday will be a bitterly cold day with gusty winds and temperatures that do not climb much, if any, through the day. That leaves us with highs in the low to mid teens and wind chills near zero. Very cold Tuesday night, lows close to zero for some and wind chills could approach 15 below zero. Partly cloudy skies become mostly clear overnight.
High pressure begins to nudge in here later on Wednesday into Thursday. Wednesday begins with a very cold morning but temperatures rebound into the 20s during the afternoon. We should see a good amount of sunshine.
By Thursday temperatures moderate well into the 20s along with partly cloudy skies.
Friday may bring a few snow showers and temperatures into the 30s. Unsettled weather could be with us into the weekend, although it appears at this time any precipitation we get will be light and most likely in the form of rain showers. Temperatures could jump well into the 40s.
