Detailed Discussion
Yesterday’s lack of sunshine not only made for a gray, dampish start to May, but it held temperatures in the 50s from I-89 east and north, about 10 degrees colder than the long-term averages. Locations west and south did manage some breaks of sun yesterday afternoon, helping readings to ease up into the 60s, closer to average for the start of May. For northern regions this morning, it’s still gray and cool, but showers and thunderstorms moved in after midnight for a soggy start to the day. This is part of a compact storm near Montreal, tracking to the east of I-89, running through NH this afternoon, and close to Boston by the end of the day. The first pulse of showers is now exiting eastern VT and splashing from central and northern NH into Maine. This leaves a relative lull in the showers, with a passing localized shower through midday. The storm’s passage southeast this afternoon, and limited atmospheric heating will stir up additional scattered showers, mostly from I-89 east and north, holding temperatures in the upper 50s to low 60s. West of the storm’s influence, especially areas west and south of I-89 should remain mostly dry, perhaps with a few elements of sun, giving thermometers a boost, reaching the 60s to a few low 70s, warmest in southwest VT and into the Hudson Valley. Meanwhile, camped out over the Canadian Arctic, high pressure will expand south through eastern Quebec behind the storm tonight, which offers some partial clearing later tonight, and a mix of clouds and sun to finish up the week tomorrow. More sun means temperatures climbing to the 60s and low 70s tomorrow afternoon. These warmer, more seasonable temperatures should linger into the start of the weekend Saturday, as interval of sunshine continue, with highs ranging from the lower 60s east to the upper 60s west, and should be favorable for Green-Up Day in Vermont. However, with a cold front approaching from the west Saturday, showers should develop in the St. Lawrence Valley, edging east through NY later in the day, progressing east and south Saturday night into Sunday. This should cool temperatures several degrees, mainly in the 50s Sunday. As long as this system keeps moving, partly sunny and seasonable weather return for early next week.
