Temperatures Drop Ahead of Wintry Sunday, Wet and Windy Marathon Monday

The big story this weekend is the plunging temperatures and the return to wintry weather by Sunday.

Saturday, we started off with filtered sunshine and temperatures near 50. Over the course of the day today, expect those temperatures to continue to slide lower.

We have a cold airmass to the north of us that will be progressing southward. A few sprinkles are possible over the course of the day today, but these will be few and far between.

By Saturday evening, temperatures will be nearing the freezing mark north, 40s south. Snow showers kick off as early as 5 p.m. Saturday for those closest to the Canadian border, otherwise mostly cloudy south by dinner time.

Showers start to fill in for most of New England overnight Saturday into early Sunday with interior Massachusetts, southern Vermont, southern New Hampshire, and northern Connecticut plunging into the 30s with sleet and freezing drizzle likely, making for tricky travel through Sunday afternoon, especially along the higher terrain in interior Massachusetts..

Sunday’s high temperature will struggle to make it out of the 30s for most of New England.

With sleet and freezing rain in the forecast over a several hour period Sunday, a Winter Weather Advisory has been issued for all of Vermont, western and central Massachusetts, including Worcester County and NE Massachusetts, and NW Connecticut.

For the runners and the spectators on Marathon Monday, be prepared for rain and wind. We start off in the 40s Monday with an onshore wind, meaning the runners will likely be battling with the wind for most of the race.

By Monday evening, temperatures will reach near 50 for southern New England as a warm front advances northward.

With that shift, we could see a few heavy downpours at times and a rumble of thunder cannot be ruled out in far southern New England Monday evening. Cold front follows suit overnight Monday into early Tuesday, making for mountain snow showers in the higher terrain of northern New England, drier and slightly cooler conditions in southern New England for Tuesday with highs into the upper 40s.

Wednesday looks to be the calm day out of the next work week, with Thursday and Friday into the 50s with a few showers.
