Detailed Discussion
Chilly weather cooled us down over the weekend, with brisk winds Saturday, and a frosty morning yesterday. But that changed quickly as cool high pressure exited to the east, opening the door for a warm front approaching from the west. Clouds spilled eastward in advance of the front, followed by showers late afternoon in NY, spreading east through central and northern VT toward evening, then edging south last night. The warm front is still to our west this morning, extending south through Quebec into eastern NY and PA to the New Jersey coast. Ahead of it, the showers have diminished, while south winds have ramped up, gusting to 40 mph from the western slopes of the Green Mountains west through NY. They’ll quickly lift the warm front east and north, with a break in the showers, perhaps some intervals of sun, especially south, before another round of showers develops later this morning in NY, spreading east this afternoon. Ahead of the showers, the winds will increase, with some gusts to 50 mph through parts of northern NY into the St. Lawrence Valley, prompting Wind Advisories through 2 o’clock this afternoon for the northern Adirondacks into the St. Lawrence Valley. The gusty south winds will encourage temperatures to climb to the upper 50s and low 60s north, and into the 60s south, the beginnings of warm, spring-like week. The warm front extends southeast from low pressure north of the Great Lakes this morning, expected to slide through Quebec to our north this afternoon. A cold front trails the storm, producing additional showers, starting late morning in northern NY and the St. Lawrence Valley, spreading east this afternoon, more numerous through northern areas. The front appears to stall to our north across southern Quebec, occasionally drifting north and south. Along with warm temperatures, chances of some showers will be an almost daily occurrence, favored in northern areas closer to the frontal systems. It also adds more uncertainty to the forecast, as the timing of the showers depends on minor fluctuations not well forecast in advance. The current situation finds the weak cold front easing south tonight, the agent of the showers this afternoon and evening. Tomorrow, the front drifts back to the north, leading to periods of showers north, and temperatures in the 60s, while sunny intervals south send readings into the 70s. The showers in the north spread east and south Tuesday night, then taper off with a similar day on Wednesday, again with 60s north and 70s south. More breaks of sun are expected south, while more clouds linger through northern areas, though fewer showers are currently anticipated. No significant changes Thursday into Friday, as warm, springtime conditions continue, perhaps into next weekend.
