Area Forecast Discussion National Weather Service Charleston WV 851 AM EDT Tue Jun 19 2018 .SYNOPSIS... A front will drift south into the region today, providing showers and thunderstorms. && .NEAR TERM /THROUGH TONIGHT/... As of 850 AM Tuesday...Decent 30 to 35 knot NW upslope flow at 850mb has most of the mountain counties under a overcast cloud cover this morning. That flow weakens in the next couple hours so some modest clearing should occur before the front drops down from the north this afternoon. Updated sky cover to reflect this change over the next few hours. As of 625 AM Tuesday... A few showers developing across our far northern counties this morning. These should wane in the next few hours. Based on the new model runs, I've nudged the highest pop axis a hair north, closer to the route 33 corridor as the front takes on a northwest to southeast orientation. As of 245 AM Tuesday... Cold front will sag into the central parts of the CWA today, before retreating off to north later this evening and becoming diffuse. I have pops ramping up into likely across the central and northern parts of the CWA by early afternoon, with the best chances looking to be along and just north of the I64 corridor...to around the route 33 corridor. While the potential certainly exists for some localized microbursts given the decent sfc-h7 theta e spread and DCAPE values, torrential downpours with the potential for training cells may be the bigger hazard. PWATs around 2 inches further exacerbates this threat. 1 and 3 hour FFG in the corridor where the highest confidence of storms hovers around 2 inches. I contemplated a somewhat narrow flash flood watch, but given the lack of shear for organized storm development, I think the threat will localized as it stands now. It should be worth mentioning that FFG is much lower across the northern WV lowlands, and if the axis of greatest storm coverage ends up being north than currently thinking, then the flash flood threat would be greater. I will probably revisit this decision with the early morning update. Highs today will be around 5 degrees lower than yesterday and despited the uptick in dewpoints, I think a heat advisory is not warranted. This is especially true given timing of convection onset. Activity will gradually diminish late this evening as the front retreats off to the north. If cloud cover is less than expected, then dense fog will likely be prevalent across much of the river valleys tonight. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... As of 300 AM Tuesday... A frontal boundary will slowly sag southward across the area Wednesday and Wednesday night, providing showers and thunderstorms. Concerned with a flood threat since the front will provide a focusing mechanism and models showing 1.9 inches of precipitable water. Meso Nam is showing some locations receiving over 4 inches of rain between now and Wednesday evening. Will need to monitor this situation closely. The front is expected to stall near or just south of the area for Wednesday night or Thursday. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 300 AM Tuesday... The front will push back northward on Friday as a warm front. This will put the area back into warm sector for the weekend, with chances of showers and thunderstorms, more numerous in the afternoon and evening hours. Another weak cold front is expected to push through the region late Sunday or Monday. && .AVIATION /13Z TUESDAY THROUGH SATURDAY/... As of 625 AM Tuesday... A period of MVFR stratus is possible at CKB/EKN 12-15Z ahead of an approaching cold front. Thereafter VFR conditions take hold amid a developing healthy cu field. This will lead to convection as the front sags into the area, with chances ramping up quite a bit by 21Z. Brief IFR conditions can be expected in convection, which will carry though early evening. This was handled with VCTS as confidence as has lowered on axis of greatest probability. The front should retreat to the north later this evening, with convection diminishing. Depending on extent of cloud cover, dense river valley fog is possible at any terminal that receives rain. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z WEDNESDAY...
