Monday, June 1 and Tuesday, June 2, 2020 Cold Pool Fun

Recommended Posts

Computer forecast models have been in strong agreement in a vigorous shortwave trough amplifying through New England yielding quite an anomalous pool of cold air aloft characterized by 500mb temperatures as low as -25C. While llvl moisture will be sufficiently lacking (dew points mainly in the 30's to 40's), the combination of very steep lapse rates (~7.5 C/KM) and daytime heating will contribute weak destabilization with MLCAPE values around 250-500 J/KG. This should be enough to spark off scattered showers and t'storms each afternoon with the attendant risks of gusty winds and hail. On Tuesday when the brunt of the air mass moves overhead, there could even be some flakes in the mountainous areas of northern New England! Lack of moisture will likely inhibit potential for severe hail.

This is going to be a bit hard to do with dewpoints only in the 30's though...so perhaps isolated is the better way to go over scattered. ughhhh only if dewpoints were like in the 50's. We would probably see golf ball hail potential
