A winter weather advisory is in place for all the areas shaded in purple, effective 11 PM tonight until 10 AM tomorrow morning. This storm won’t be a blockbuster by any means – there’s just not enough energy or moisture to work with. Precipitation should generally be light and accumulations, low. The issue at hand is that the storm will coincide with Monday morning rush hour. Let’s break down the details…
Timing: Snow develops from south to north around midnight tonight, changing to rain quickly along the south coast and Cape, the snow will transition to a period of sleet and freezing rain from the MA turnpike to the MA/NH border from mid morning to midday respectively as relatively “milder” air works into the region. Pockets of wintry mix will linger longest from the Rt 2 corridor into southwest NH. Otherwise, it’s plain rain showers for everybody during the afternoon, tapering in coverage by evening.
Accumulation: With a wind off the ocean, the coastline will see little if any snow, which will then be washed away by the rain anyways. The “highest” amounts will be focused across the interior, especially along & outside of 495. Any ice accumulations should be limited to a trace to 0.1”. Untreated surfaces will be slippery tomorrow AM.
So putting this all together, this round of wintry weather ranks as a 1, or low impact, on our iScale. The bottom line here is that the timing is unfortunate. Because of that, there may be some delays for schools tomorrow along with hazardous driving conditions. Be sure to take it slow on the roads, leave extra time for your commute and tune in to WBZ for the very latest forecast from Todd Gutner in the AM.
I’m filling in for Barry tonight, so if there are any significant changes to the forecast, I’ll update you here too.
Have a great day & go Pats!
