The steady rain that soaked the Finger Lakes through Wednesday afternoon and evening will gradually taper off from west to east overnight, clearing out by early Thursday morning. A shortwave trough pushing through the Great Lakes is driving the system, with a surface low tracking toward the Saint Lawrence Valley late tonight — that’s what finally pulls the rain away.
Overnight lows will drop into the upper 40s to low 50s across the region, with northern spots like Canandaigua and Penn Yan dipping coldest. No frost tonight, but that changes soon: the NWS is watching Thursday night through Sunday morning for potential frost or freeze conditions as cool, dry air settles in behind the departing system.
Thursday looks mostly dry with temperatures recovering into the mid-to-upper 50s, but don’t put the jacket away — an unsettled pattern returns late in the week and holds through early next week.
