As of 645 PM Sunday... Minor adjustments to the grids this evening. Still looking at a quiet Monday morning with clearing having already occurred or still occurring with below freezing temperatures to start the morning. As of 120 PM Sunday... Upper level disturbance is starting to enhance precipitation this afternoon. This disturbance will provide deeper moisture as Lake Michigan plume shifts into northern WV. Expect a period of decent upslope snowfall over the northern mountains this afternoon and evening. Will continue with the winter weather advisory for the higher elevations. A high pressure system then builds over the region providing clearing overnight, remaining in place on Monday.

&& .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 140 PM Sunday... Clear skies and slightly below normal temperatures will remain across the forecast area Monday night. This is in part thanks to an area of surface high pressure. The high will slide east making way for warm southwesterly winds to push Tuesday highs into the 50s to near 60 south. However, this brief warmup will be short-lived. The next cold front will bring another round of cold temperatures to the Region. This front is expected to traverse the Ohio Valley and Mid Atlantic overnight Tuesday into Wednesday morning. While there is limited moisture associated with this system, there could be some brief showers or snow showers into the overnight hours Tuesday into Wednesday morning. The best chance for such conditions is the northern sections West Virginia into the higher elevations of the WV Mountains. Conditions should improve quickly Wednesday as surface high pressure takes control and scours out any lingering low level moisture. As previous forecast stated, clouds should remain in place thanks to the upper shortwave through this time. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 140 PM Sunday... Fairly quiet weather to start this time period. High pressure hangs on with warming temperatures. It is not until the weekend when conditions once again deteriorate. At the present time, models are leaning toward another strong cold front moving across the area. While this front does not have a lot of moisture with it, the chance for gusty winds and some showers do exist. Will have to keep an eye on this system as the week progresses as it is a major travel week. No significant tweaks were made as models are in good agreement at this time. && .AVIATION /00Z MONDAY THROUGH FRIDAY/...
