Big weather changes are arriving to New England in the coming days as a well-advertised shift to a cool, autmun weather pattern takes hold. The first of the changes today is actually a final gasping push of warmth, clashing with the cool air that was in place already in New England, bringing many clouds and some showers and sprinkles from time to time Tuesday morning through early afternoon. By late Tuesday afternoon, breaks of sun will emerge and nudge late day temperatures to their highest values of the day, reaching the 70s for Southern New England, while Northern New England stays mostly cloudy and cooler. New showers will develop in Northern New England Tuesday evening and night with patchy fog developing region-wide as more humid air arrives to Central and Southern areas, making for a humid and warm start Wednesday. Though temperatures will likely rise into the 70s for most of us Wednesday, a strong cold front will already be marching south through Northern New England early Wednesday and likely drive temperatures down by the end of Wednesday as scattered showers crop up, marking the change in air. From Wednesday evening onward, it’s all fall: highs in the 50s Thursday, Friday and Saturday…and likely nothing much above 70 on even the warmest days in the exclusive First Alert 10-day forecast. Rain chances start to rise, as well, with one shot of rain Thursday evening into early Friday morning, then again late Sunday into early Monday.
