Need to take the mind of Corona for a bit.
A vigorous piece of shortwave energy diving southeast through Canada Thursday swings a cold front through the region late morning/early afternoon. The synoptic setup presents an intriguing spring-like look. The main sfc low projected to pass through central New England prevents the warm front from lifting through the region, meanwhile a weak area of high pressure northeast of ME helps keep colder air locked in place across northern New England with colder air being reinforced by the passage of the (strong) cold front. As the shortwave amplifies upon digging through southeast Canada rather impressive dynamics develop aloft with a 500mb jet streak exceeding 120-130 knots overnight Thursday. The result from this system...a significant spring snowstorm across ME with rain and an embedded line of t'storms moving through southern New England on Thursday.
While the warm front never gets into southern New England, an airmass characterized by dewpoints climbing into the mid-to-upper 40's, temperatures into the 50's, and fairly steep mid-level lapse rates (~7 C/KM) will result in modest elevated instability. This combined with the strong dynamics aloft and forcing from the cold front will result in the development of a low topped squall line which may be capable of producing localized damaging wind gusts and perhaps some small hail.
Meanwhile, in northern ME a several-plus hour thump of heavy, wet snow is likely given favorable thermal profile and strong lift through the DGZ. Combination of strong winds and heavy, wet snow may result in isolated-to-scattered power outages. Given the vigorous lift with this system and influx of warmer and more moist air into the CCB, there will likely be a band of extremely heavy snow (rates 1.5''-2''/hr) which may yield a narrow band of 12-20'' of snow.
Fun day in store!
