Possible Nor’easter Could Hit Region Later This Week

Dry air associated with a high-pressure system means fair weather for New England Tuesday and Wednesday. Keep in mind that high pressure means high barometric pressure, associated with sinking air – the opposite of what’s needed for significant cloud and storm growth.

The result is another two bright days in a string of favorable weather. However, one could argue whether Tuesday qualifies as a spring or winter beauty, as chilly air holds temperatures in the lower 40s.

A light breeze caps wind chill values in the 30s at the warmest time of the day Tuesday. An afternoon disturbance aloft may deliver some building clouds and even a few flurries, particularly to western New England. Our dry air will limit the growth of these clouds and clearing will take hold Tuesday night with lows below freezing.

A shifting wind will blow from the south Wednesday, helping to boost temperatures close to normal for the date as we near 50, in advance of our next storm.

The next weather-maker comes Thursday as a possible nor'easter– the product of intense energy diving southeast from Canada and interacting with available moisture from the Gulf of Mexico.

The initial result should be Thursday rain showers developing and ramping up later in the day with the possibility of snow in the mountains. It’s now looking more likely Thursday night will deliver a shot of steady and heavy rain and mountain snow into early Friday morning.

Meanwhile, high tides due to lingering effects from Tuesday night’s full moon raise the possibility of coastal flooding at both the Thursday and Friday midday high tides. A blast of cool air follows the storm Friday with some snow showers possible and Saturday for a blustery day.
