As of 1020 PM Wednesday... Previous forecast remains on track. No changes needed at this time. As of 607 PM Wednesday... After coordination with SPC, decided to cancel Severe Thunderstorm Watch at 411 PM. However, radar is showing additional convection moving into our area from KY and OH. Expect this convection to diminish in coverage and intensity this evening. Localized heavy downpours still possible through this evening. As of 230 PM Wednesday... Key Points: * Severe Thunderstorm Watch for portions of southwest Virginia and the foothills and mountains of West Virginia until 10 PM. * Flash flooding concerns arise through this evening as repetitive showers and storms pass over already compromised soils. Active weather is ongoing this afternoon as the forecast area remains planted within an unstable atmosphere due to passing frontal boundaries. At the time of writing, a few strong to severe storms were being closely monitored in addition to flash flood warnings within the southern coalfields and the Ohio River Valley. Due to the strong nature of storms already observed today, a Severe Thunderstorm Watch will be in effect for the eastern extent of our forecast area until this evening as enough destabilization has transpired to help maintain storms as they press into this part of the area. Storms will be capable of producing damaging wind gusts and hail, along with possible rotation as we see an increase in shear today in comparison to the past few days. Heavy downpours accompanying today`s convection has already led to around an inch to inch and a half in rain across the board, with local amounts as high as two and a half inches. Given how compromised the ground has become over the past few days due to daily showers and storms, the opportunity for localized flash flooding will be on the rise. Showers and storms will grow slimmer in coverage and intensity as the evening wears on due to the loss of daytime heating and the leading edge of storms traveling into the Mid-Atlantic region. Afterwards, excess moisture will once again be conducive for river valley fog late tonight into Thursday morning. After a quiet few hours in the wake of morning fog erosion, renewed precipitation will transpire for the afternoon and evening. Current projections keep the bulk of severe weather east of the Appalachians and the best chance for excessive rainfall along the spine of the mountains and eastward.

&& .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... As of 230 PM Wednesday... Daily opportunities for showers and storms continue through the forecast period as a series of frontal boundaries peruse the area. As convective temperatures are reached each day, coupled with dew points rising into the upper 60s/70s, scattered activity will flourish through the course of the afternoon and evening hours. As soil conditions continue to be compromised by daily heavy downpours, the potential for high water issues will grow more widespread. Storms then settle down across the Central Appalachians late at night, but lingering excessive moisture will yield river valley fog during the predawn hours. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 230 PM Wednesday... Active weather looms for the end of the weekend into the start of next week as surface frontal boundaries sail across the area. The trend will remain of showers and storms sparking during peak heating hours and diminishing in coverage after sunset with the loss of instability and activity pushing east of the mountains. Daytime temperatures and dew points remain consistent through the extended period, yielding hot and muggy conditions for the middle of July. Amendments may be warranted today in the event a storm passes close by to a TAF site. && .AVIATION /02Z THURSDAY THROUGH MONDAY/...

As of 731 PM Wednesday... Showers and thunderstorms will diminish in coverage and intensity this evening. Strong convection will continue to affect the area and some of our terminals through this evening. Expect brief periods of IFR/LIFR visibility under these showers or storms. Post rainfall IFR/MVFR ceilings will probably develop early tonight into Thursday morning. Dense fog will be possible as well over areas that received recent precipitation. Any fog that does form will gradually erode after daybreak and give way to another day conducive for afternoon showers and storms. Light and variable winds will become calm overnight tonight, and then light and variable on Thursday. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z FRIDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing of improving conditions this evening may vary from forecast. Timing and extent of IFR ceilings under low stratus may vary from forecast. Fog could be more widespread and dense overnight tonight.
