Cool and dry air was reinforced early Thursday morning with the passage of a few predawn flurries caused by a disturbance aloft that left another day of sunshine in its wake.
With little wind, the wind chill factor again hovers just shy of 30 but is nothing incredible for late December.
To our west, a sprawling storm center is delivering Northern Plains snow, Midwest rain and wind, and southern severe thunderstorms and tornadoes, and that storm is moving east toward New England.
Expect clouds to thicken Thursday night and by 3 a.m. to 6 a.m., west to east, respectively, a mix of snow, sleet and freezing rain will fall.
A quick change to rain is expected from Hartford to Boston, but the change to plain liquid will take longer farther to the north. In fact, plowable snow is expected across nearly all of Northern New England before a change to mix and rain, while roads may need brief morning treatment even in Boston’s Metrowest to Northern Connecticut before milder air to the tune of 50 degrees moves in on a gusty south wind.
Cape Cod will see the strongest of the wind gusts, exceeding 50 mph by day’s end.
Rain breaks into showers Friday evening and departs by Saturday, leaving a windy day of falling temperatures from an early high near 50 in spots, yielding to northern mountain snow showers as colder air arrives, heralding a sharply colder by dry Sunday.
New England’s next storm approaches from the southwest on New Year's Eve, and while it may commence as a wintry mix, it seems quite likely to be another rain event for Southern New England with the best chance of holding onto snow in Northern New England.
That storm should be quick-moving, leaving drying conditions on New Year’s Day and cool air for the midweek with another disturbance possible Thursday.
