A burst of winter returned to the region tonight. Thursday expects to be mostly sunny with temperatures in the mid- to upper-30s across the Genesee Valley. But "copious amounts of moisture" are expected to cause significant precipitation this weekend, according to the National Weather Service, with up to 2 inches of rain Friday and Saturday. By Sunday, it could be cold enough for that precipitation to return to a wintry mix.
Blustery conditions around 5 p.m. tonight in Le Roy as temperatures were on their way into the teens. Warmer temperatures are expected for Thursday, with showers possible Thursday night.
Friday brings another change, however, as a sharp frontal zone is expected to stall near the Lower Great Lakes Friday through Saturday night, according to the National Weather Service.
Several waves of low pressure will move along this front and combine with copious amounts of moisture to produce heavy precipitation across Western and North Central New
York. This will result in periods of soaking rain, with rainfall
amounts possibly exceeding 1.5 to 2.0 inches. This may result in an increased potential for flooding, the Weather Service said.
There is a small chance that temperatures may get cold enough late Saturday night and early Sunday to change precipitation to a wintry mix, but at this time the majority of the precipitation is expected to fall as rain.
