&& .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/... Finally, a break in the snow showers is expected late today and tonight as the cold pool aloft drifts toward the northeast and a drier air mass fills in behind. But the respite will be brief. Another cold front will swing through early Thursday morning with a reinforcing shot of cold air. This will invigorate snow showers for a majority of the lower elevations, but could lead to appreciable accumulations in the highest elevations of Tucker and Garrett Counties. Will need to monitor this heading later into the week for potential headlines. Snow shower coverage will wane Friday morning and become confined to the ridges and I-80 corridor. Clouds will also decrease from southwest to northeast, with most locations seeing sunshine by late afternoon. Temperatures will continue to be well below average. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... The next system approaching the area Saturday will slide south of the broad trough and south of the area. Will carry low PoPs south of the Mason-Dixon to account for potential phasing of the two. The forecast will then dry out a brief period before the next disturbance arrives early next week. Temperatures will remain on the cool side of average through Saturday before a brief warm-up is expected. && .AVIATION /08Z WEDNESDAY THROUGH SUNDAY/... An upper low across the region should maintain isolated snow showers overnight. Brief restrictions are possible in the snow showers. Ceilings will lower to MVFR late tonight as a mid level trough axis crosses, and some local IFR is possible for FKL/DUJ where lake enhancement to the snow is expected. Scattered snow showers and MVFR/local IFR restrictions are expected today. Improvement to VFR is expected by late aftn under building sfc ridging and dry advection. OUTLOOK... Periodic restrictions are likely through Friday with persistent upper troughing and cold NW flow. && .PBZ WATCHES/WARNINGS/ADVISORIES...
