... Dry weather is expected Tuesday under high pressure. Rain chances return Wednesday mainly along and north of I 80 with a weak cold front.
NEAR TERM /UNTIL 6 PM THIS EVENING/... Dry weather is expected today as high pressure continues building into the area behind the exiting cold front. Current satellite shows cirrus spread across the region with areas of stratocu within the NW flow. While the cloud cover continues to gradually decrease from west to east, its effect has been to keep temperatures warmer than forecast. Much of the area remains in the lower 40s at this time. These warmer temperatures will preclude any development of frost and should significantly limit below-freezing temperatures this morning.
SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... Low clouds will increase late tonight and remain over the region through much of Wednesday as another cold front swings through the area. At this time, it appears greatest rain chances will remain along and north of I-80 beginning Wednesday morning. Given lack of available moisture in the snow growth zone and above freezing soil and surface temperatures, snow accumulation Wednesday night seems unlikely. However, given temperature profiles, have included a Chc/SChc mix of rain and snow across portions of Mercer, Venango, Forest, Clarion, and Jefferson counties late Wednesday night with the possibility for a few flakes to mix in.
Tuesday and Wednesday temperatures will run below seasonal averages with continued cold air advection. Despite clearing skies, Thursday's temperatures will remain on the cool side as the sfc high and upper ridging build into the region.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Warmer... though still below-normal... temperatures return Friday as upper shortwave ridging passes over the area. However, the ridge will be short lived as a persistent Rex block in the wrn CONUS supports cold air diving into the ern CONUS and an eventual broad trough for the weekend.
Rain chances will increase Friday afternoon through Saturday as warm air advection ahead of an approaching shortwave trough offers yet another gloomy day of clouds and cold rain. Rain chances will decrease on Sunday, but lake-driven stratocu will persist as cold air advection ensues.
