NWS ALY Discussion
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
Friday through Sunday, the GFS and GFS-FV3 latch onto the Pacific system and attempt to phase this feature with the digging polar vortex with a strengthening storm across the Ohio Valley and Great Lakes into the first weekend of March. The ECMWF is a bit more progressive with a reduce impact of QPF across the region.
Due to low confidence forecast, we will keep PoPs in the 30-50% categories with the highest values set for Saturday with some form of a frontal passage. Regardless of QPF, seems likely unseasonably chilly temperatures are expected this weekend as H850 temperatures and ensemble means point toward values close to -20C. Some lake effect snow will be probable into portions of the Dacks and western Mohawk Valley.
