Late Tuesday though as the shortwave and associated sfc low race
across the region, there is loose agreement that a quick change back
to snow could be in the offing from west to east. System is high
tailing it to the east by that time thanks for very strong upper jet
running out ahead of the longwave trough, but could be just enough
overlap of the cooling and lingering qpf to generate minor snow
accums as the cold air sweeps across the region. Does not look like
even moderate snow accums at this time though given the progressive
nature of the system. And finally, even with decent cold air moving
in behind the system for the rest of Wednesday (well H85 temps of
-15c on the GFS are at least decent compared to what we have seen
recently), any lake response looks to be muted due to significant
dry air advection as high pressure builds in quickly. Those details
could certainly change especially if the system comes in stronger
in future model runs, but that is how it is looking at this time.
