Behind a cold front which brought significant winds and severe storms to the area on Tuesday (familiar to the front that came through a few weekends ago), cooler air will make its presence felt in the Northeast US beginning on Wednesday.
West-northwest winds will help usher in drier air, which will be the biggest difference you’ll feel upon venturing outside during the mid-week. The humid air and gulf moisture which advected into the area on Tuesday ahead of the cold front has been swept out of the area, and the upper level trough approaching the region will bring the cooldown. Temperatures on Wednesday Night into Thursday morning are forecast to drop into the mid to upper 40’s inland, and lower 50’s in the city and urban areas. Across parts of New England, forecast models are hinting at the potential for temperatures to drop into the 30’s under clear skies and light winds!
The cooler air will moderate with time, as we will observe a warming trend in mid-day temperatures by the end of the week. However, it looks like more upper level troughs will progress towards the region (minus the big warm ups and storms ahead of them), likely keeping the weather on the cooler side of normal through the near future.
Wednesday: Cooler, but bright sun returns. Noticeable drop in humidity and much less wind. Still a bit of a breeze out of the northwest. Highs in the mid 70’s.
Thursday: Highs barely scrape into the lower 70’s with cool northwest winds prevailing. A cool start in the morning, too, with temperatures in the upper 40’s to lower 50’s.
Friday: Warmer than the past few days as the airmass begins to modify a bit. Highs in the middle 70’s, warmer in some spots. Light winds.
