&& .NEAR TERM /THROUGH TONIGHT/... As of 300 AM Monday... Satellite and radar images, and sfc obs suggested that the cold front was located along southeast OH at 3 AM, moving slowly east. The showers and storms activity along the cold front have decreased considerably overnight. Kept previous PoPs as they denoted a decreasing trend and have lingering showers over the east. The latest is supported by the high resolution model solutions. High pressure builds behind the cold front to bring clear skies and dry air mass to the area. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... As of 230 AM Monday... Not too many changes in the overall forecast. Weak low pressure will pass to our south and east on Tuesday with the best forcing remaining well to our east. I did bring in a chance for showers with highest PoP in the mountains, but guidance is in good agreement with keep any heavy rain in Central Virginia. Deep upper trough digs over the region on Wednesday. Strong surface low tracks up the Ohio Valley and into the Great Lakes, dragging a cold front through the region Wednesday night. This will spread widespread showers and possibly thunderstorms into our area, but with relatively low PWAT values we are not expecting any issues with flooding. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 240 AM Monday... Start the period with deep upper trough overhead and then sliding east of the area Thursday night. There will be a chance for a few showers on Thursday, but brief ridging start to build in later in the day. The pattern turns zonal thereafter and several waves move through the flow that will keep conditions unsettled through the weekend. && .AVIATION /10Z MONDAY THROUGH FRIDAY/...
