Looking like a chilly day for the western part of the CWA tomorrow behind the trough while CNY warms out ahead of it...
A sharp mid-level trough axis extending from a closed low across
James Bay will very slowly move from west to east across the area
Friday and Friday night. Overall good model agreement on this
feature with widespread showers along the leading edge of the mid-
level trough axis and with a weak surface low reflection. Expect
rainfall amounts to average between a quarter and half an inch as
this moves through. Friday will be a cool and rainy day across
Western New York, with steadier showers then focusing east of Lake
Ontario Friday night. Expect highs only in the 40s west of Rochester
on Friday, with lows in the 30s Friday night. 850mb temperatures
drop to -3c Friday night, where even a few wet snowflakes cannot be
completely ruled out across higher terrain.
