... Scattered rain showers are possible Thursday, with both rain and snow showers possible north and in the ridges on Friday as low pressure crosses.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Favorable jet circulation and frontogenesis has accompanied the propagation of the stalled cold front to the east, ending precipitation chance. With lack of upper level support and shortwave ridging, the area should remain dry overnight with seasonable temperature.
SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... Vorticity advection associated with the aforementioned low pressure will arrive aloft in the region Thursday morning aiding eventual scattered shower development. This precipitation chance will last through Friday, tapering gradually.
Most notably, a reinforcing surface cold front associated with mature low pressure on Thursday afternoon will usher in much colder, drier air and gusty winds due to isallobaric acceleration. Areas north of I80 could see a sudden transition from rain to snow showers. With the ambient temperature being near or above 45 degrees, shear orthogonal snow showers are possible and may result in drops in visibility but shouldn't cause too much issue with road temperature being warm. There is virtually no flash freeze potential as low temperature on Thursday night only drops to the mid 30s.
Thermal profiles suggest portions of the I80 corridor and higher terrain could see snow mixed in amid continued cold advection Friday morning, but accumulation will be light and limited to the ridges of WV. Dry conditions and a clearing sky is generally expected Friday night with increasing subsidence and height rises as the upper low shifts toward the Atlantic.
LONG TERM /SATURDAY THROUGH WEDNESDAY/... Periodic rain chance with near to slightly below seasonal average temperature is likely into early next week as a progressive flow allows for a series of shortwaves to impact the region.
