After one shot of cool fall air already delivered morning lows in the 30s for most of New England this morning, another, reinforcing cool airmass is moving in today.  The leading edge of the new cool air is called a cold front and will carry a band of clouds and showers from north to south today from morning to evening, respectively, with most of Central and Southern New England seeing scattered late day to early evening showers. Behind those showers, a gusty southwest wind shifts to blow from the northwest with gusts to 45 mph at times – not as strong as a couple of nights ago, though a couple isolated reports of tree damage are a possibility.  The new, northwest wind will deliver enough chilly air to hold high temperatures in the 40s Thursday with wind chill values starting in the 20s in the morning and never recovering beyond the 30s by afternoon. Of course, this sets us up for a frost and freeze deep into Southern New England Thursday night, away from the coastline, so we’ll want to bring in any plants we’re hoping to save.  Temperatures rebound Friday and even more Saturday, though the incoming warmth will produce some clouds with a chance of showers Friday night into Saturday morning, then perhaps a lingering scattered shower during the day Saturday with more numerous showers in Vermont.  A renewed shot of cool and dry air arrives Sunday with mountain snow showers and cool air holds all the way through next week in the exclusive Early Warning Weather 10-day forecast.
