Detailed Discussion

Some late winter weather lingered over the region this weekend, with some light accumulations, especially over the higher terrain to start, then a quiet day tomorrow. But the early sun yesterday gave way to clouds, a signal of an approaching storm that has several Advisories out this morning, some continuing into Tuesday. Deep low pressure in the Great Lakes, sweeping a blizzard through parts of the Midwest, will churn the atmosphere as it heads northeast, forcing a warm front north through here today, then pivoting a cold front across the region late tonight, quickly returning some late winter conditions to the area. The warm front extends from the storm over lower Michigan, curving northeast into Ontario, then southeast through NY and east across Long Island. The cold front rides gusty winds quickly behind it, also arcing northeast, then south through Cleveland, the mountains of Virginia and the Carolinas, through Atlanta to the Florida panhandle. Marginally cold air here this morning has made for a few spotty areas of freezing rain in northern NH, with Winter Weather Advisories there through noon, but generally changing to rain showers. The warm front lifts north this morning, drawing one band of showers through this morning, then scattered east of the Green Mountains, isolated west this afternoon, before additional rain and showers spread east tonight. The showers and warmer temperatures will send excess water into the rivers and streams in NH, where a Flood Advisory has been posted by the National Weather Service this afternoon through Tuesday afternoon. The strength of the storm will increase winds, creating gusts to 40 to 60 mph later this morning into Tuesday morning, resulting in Wind Advisories for all areas except northern NH, and High Wind Warnings for the Adirondacks. Along with increasing rain showers late this afternoon, and periods of rain this evening, the cold front changes the rain to snow showers, starting in the St. Lawrence Valley after midnight, racing to NH by daybreak. At the same time, the moisture will ride the strong winds north, so that accumulations will be limited, mainly over the higher terrain north, up to an inch, and up to 3 inches in the Adirondacks. Rather cold air for mid-March plunges in behind the front, leading to steady or falling temperatures tomorrow, dropping to the single digits and teens by Wednesday morning. The rest of the week looks quieter, with only a minor system slipping through northern areas later Thursday into Friday, with perhaps some limited snow showers, while temperatures ease up, though still below average as we approach the Spring Equinox on Friday. It appears more surges of cold weather could follow next week, holding any progress in spring weather at bay.
