Cold advection will change the precip over to all snow late Friday
afternoon or early Friday evening. An area of deep wrap around
moisture, northerly upslope flow, and some lake response (H85 temps
-10c or so) may produce at least some snow accumulations later
Friday through Saturday morning. Early for sure, but if ECMWF
pattern and QPF verifies (been showing this for a few days now),
then somewhere across the Niagara Frontier would probably have at
least a few inches of snow by Saturday morning. This system pulls
well offshore into the Atlantic on Saturday, with limited snow
showers south of the lakes ending by Saturday afternoon. High
pressure will then bring dry weather Saturday night and Sunday, with
a warming trend still on track for early next week
