&& .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... Sunday night will remain dry as the ridge continues to slide east. Rain will be possible sunday afternoon and into the evening as the next cold front quickly crosses the region. Scattered snow showers will be possible behind the front however, any significant accumulation is unlikely. Cold air advection behind this front will be relatively weak, but a secondary front and upper level disturbance will bring a shot of colder air to the area on Wednesday. This continental airmass is dry and no precipitation is forecast to accompany the front, only stronger northerly winds, a drop in temperatures, and continued dry conditions. Overnight lows Wednesday night / Thursday morning will be quite cold if surface winds decouple as limited cloud coverage would allow for a strong radiational cooling night. && .LONG TERM /THURSDAY THROUGH SATURDAY/... Thursday flow begins to turn more southerly and temperatures will begin to trend up. Precipitation chances return for Thursday night and Friday as warmer air and moisture build ahead of the next trough. A frontal passage on Saturday will bring more rain chances. && .AVIATION /16Z SUNDAY THROUGH THURSDAY/... IFR to low MVFR conditions are expected to continue this morning with an exiting upper low. Lingering low level moisture behind the low should maintain these conditions through much of the morning. Improvement to MVFR for all ports is expected by late morning/early afternoon as high pressure begins to build in. A clearing trend is expected tonight as the high moves over the area. Outlook... Restrictions are likely with the approach and passage of a Mon/Mon night cold front. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$ is the U.S. government's official web portal to all federal, state and local government web resources and services.
