Nice AFD from BUF! Satellite estimates of a warm patch in Lake Erie at 38* still? That’s a curveball! Although cold air advection will weaken some, delta T`s reach 13 degrees by Friday morning with 850mb temperatures dropping to -14C. Satellite estimates a "warm" patch of water on Lake Erie of near 38 deg F near Long Point. Low pressure will track from Lake Superior to Georgian Bay overnight and a cold front will move across Lake Erie. This shift in the wind will produce a lake response with lake effect snow showers beginning across western NY. This front will likely produce a light snow across the region while a lake band forms on a 250-260 wind along the Lake Erie shoreline into southern Erie and into Wyoming and Genesee counties overnight and be south of the City of Buffalo by the Friday morning rush hour, with the northern edge of the band producing at least light snow over parts of the Buffalo Metro. Snow will become heavy at times with snow rates 1 in/hr with localized amounts of up to 2 in/hr. This band will slowly move southward into the Southtowns and extreme northern Chautauqua and Cattaraugus counties through the morning. The band will likely lose some intensity as mid-level moisture diminishes however snow will continue. .
