... Scattered snow showers are expected Wednesday with the approach and passage of a cold front. Dry and cold weather is then expected through late week under high pressure.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Stratocu should continue to persist through the night, though some reduction in coverage is expected as ridging briefly builds in. Additional clouds are expected to move in later tonight ahead of an approaching cold front. Snow shower chances should also return toward morning N of I 80 with the approach of the front. Lows are expected to average around 5 degrees below seasonal levels.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/... The ern-CONUS trough will deepen in response to an amplifying wrn-CONUS ridge that will shift slightly ewd tonight and Wed. Cyclogenesis nw of the Great Lakes region will produce a sfc low that will deepen rapidly and shift ewd across sern Canada by Wed afternoon.
Cold air will funnel into the region as this system passes to the north, with trajectories favoring lake enhancement Wed into Wed night, especially along and north of I-80. Minor snow accumulations will also be possible along the ridges and higher elevations. Little to no snow is expected across the srn zones.
Dry, cold arctic air arrives Wed night as high pressure begins to build in from the west. Temperatures Thu morning will be the coldest yet this season, with much of the area dropping into the teens.
Cold air advection will keep Thanksgiving afternoon temperature mainly in the 20s, even with diurnal heating under a mostly- clear sky. Maxima will struggle to reach 30F for all but the far-swrn portion of the area, and locations n/e of Pittsburgh will struggle to exceed the low-mid 20s.
LONG TERM /FRIDAY THROUGH TUESDAY/... Sfc high pressure and an upper ridge begin to shift ewd on Fri. Upper ridging will support closer-to-seasonal temperature in the 40s Fri afternoon amid increasing warm advection, especially for the swrn half of the forecast area.
Precipitation will develop late Fri night as warm advection strengthens. Given the cold air preceding its onset, there is a chance for a brief wintry mix of snow, sleet or freezing rain before the warm air dominates, bumps the temperature up to the upper 40s and changes all precipitation to liquid rain by mid- day Sat.
