DAYS 1-5 (MARCH 9-13)
A push of warm air brings the feel of spring and obliterates most of the remaining snow cover today and Tuesday as high pressure sits to our south and low pressure moves well to our north. As this low head into far eastern Canada, high pressure building in east central Canada will send its front southward and the cold water of the Gulf of Maine will help accelerate this process so it comes through as a back-door cold front Tuesday night and early Wednesday, returning chilly and raw air to our region, along with lots of clouds. At the same time, additional clouds would be coming in from the west anyway as low pressure enters the Great Lakes. This will drag that boundary back through as a warm front Wednesday night, combined with low level moisture from the ocean it will result in drizzle and rain showers, putting us briefly back into a wedge of warmer air early Thursday before a cold front moves through from west to east. This front will be accompanied by widespread rain showers that may mix with or turn to wet snow especially in higher elevations as the front goes by and returns colder air to the region from west to east. This leads to a chilly Friday, and any clearing is reversed as another system heads our way from the west, bringing the chance of snow/mix/rain by Friday evening. Details on that system are to-be-determined.
