Forecast discussion: The cold front passed through during the late morning Sunday, stopping the precipitation over Boston. Eastern Massachusetts received light to moderate snow until about midnight, before the precipitation changed over to freezing rain and rain. By 6:30 a.m., colder air returned to the northern part of the state. The rain changed back to snow, before ending around 10 a.m. By this afternoon, sunshine broke out, and temperatures went above freezing. Speaking of temperatures, here’s a quick, fun fact. In Boston, this is the second coldest February on record. The average for the month has been 18.2 degrees. The coldest February on record was 17.5 degrees, way back in 1934.
High pressure coming into North Dakota will keep skies clear tonight. But, with temperatures going above freezing, plus the rainfall, helped to melt some snow packs, and create puddles and even small rivers within the secondary streets. So, if you have to commute Monday morning, please be extremely cautious.
With winds increasing in the early morning, a Wind Chill Advisory is in effect up to Norwood, starting 6 p.m. Monday until 8 a.m. Tuesday. High temperatures will only reach 20 degrees Monday, as a new cold front will pass through during the early afternoon. Light winds and clear skies Monday night will make for bone chilling low temperatures, as some areas may see 5 to 10 below. We will only warm up to 20 degrees on Tuesday, before increasing cloud cover helps to keep overnight lows Tuesday night in the upper teens.
We will lose the influence of the strong high early Wednesday morning, as an Alberta Clipper system pushes through eastern Canada. The cold front will help trigger light snow showers through most of Wednesday. However, it appears a possible coastal storm will no longer threaten Southern New England. But, an inch or two of snow is possible before the flurries end early Wednesday evening.
The rest of the week looks dry, but cold. Once again, a new cold front will push through the region, helping to keep an upper level trough over the eastern U.S. High temperatures will struggle to reach the lower 20’s Thursday and Friday, and overnight lows will fall into the single digits. Temperatures will warm slightly on Saturday, with extra cloud cover Saturday night. This will help push low temperatures into the middle teens. By next Sunday, a storm system may bring enough warm air back into New England to keep possible precipitation as freezing rain or rain. But, temperatures during the evening may change the precipitation back to light snow into next Monday.
