Little to no change in the overall forecast. && .KEY MESSAGES... 1) Dry and trending milder through Friday followed by a return to isolated to scattered showers through the weekend and into early next week. && .DISCUSSION... KEY MESSAGE 1: Dry and trending milder through Friday followed by a return to isolated to scattered showers through the weekend and into early next week. The closed low which has been situated off the NY/NJ coast the past few days will begin making better headway northeast today as an open wave. By late tonight, this feature is expected to be centered just south of the Canadian Maritimes. In response, upper level ridging is expected to take place over the Appalachians. What was has been generally a northerly flow pattern across our region will transition to southwest tonight. The result will be a loss of the low- to mid- level cloud shield which has been blanketing much of the eastern half of our region. Increasing heights and the onset of warm air advection will yield progressively milder temperatures across the region through Thursday and Friday. As we reach Friday, the center of the upper ridge is expected to be shunted southeast of the region with the approach of a cold front. This front may bring isolated showers to the far western sections of the region as early as late friday afternoon. However, chances will increase Friday night into Saturday as the front moves into, and perhaps stalls over our region. Timing and impact are still low on the confidence meter, but moisture from what now is Hurricane Polo over southern Baja California, may have progressed across southern CONUS by early next weekend to interact with this front. As such, rainfall amounts, coverage and duration across our region may be impacted. To add to the timing/impact/interaction question mark, a northern stream shortwave trough may bring a reinforcing cold front to our area by late in the weekend. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... Area of low end VFR stratocu clouds continue over much of the region with pockets of MVFR across the mountains. Cloud cover is expected to gradually decrease heading into and through Tuesday morning. Where cloud cover is the least, we still could see some pockets of sub-VFR fog/mist by daybreak, buy any should last long after sunrise. Surface winds will remain generally light and variable. Off the surface, a northerly wind will trend southerly, especially by tonight. EXTENDED AVIATION OUTLOOK... Primarily VFR conditions expected through Friday. Better chances of sub-VFR conditions through the weekend into early next week as precipitation become more probable. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ DISCUSSION...DS AVIATION...DS
