764 FXUS61 KRNK 272308 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 708 PM EDT Fri Jun 27 2025 .SYNOPSIS... A cold front approaches the region on Saturday, with another round of scattered storms. The cold front looks to stall just north of the area, which will keep much of the region under the influence of the warm and humid airmass across the southeast. This will keep the chances for daily showers and thunderstorms in the forecast through the early to middle of next week until a much stronger cold front looks to push through the area. && .NEAR TERM /THROUGH SATURDAY/... As of 700 PM EDT Friday... Key Messages: 1) Slow moving widely scattered storms may bring localized flooding and damaging winds this evening mainly north of U.S. 460 and the Roanoke River east I-81. 2) The area will continue to remain hot and humid across the area Saturday, with another round of scattered storms. Starting to see a ramp up in convection from the Alleghanys southeast to the Roanoke Valley and into southside VA just southwest of a convergent boundary per mesoanalysis. Storm motion remains slow and will have to watch for localized flash flooding. The current watch will remain as is for now. Previous discussion... The surface high pressure that is leading to a backdoor front that is currently draped across the Virginia Piedmont should lift north tonight as a warm front as the surface high pressure progresses east into the Atlantic and losses influence over the region. As this happens a shortwave trough and associated surface low pressure system is expected to push across southeastern Canada during the day on Saturday. The associated cold front is forecast to be draped across western New York and into the Ohio Valley by Saturday evening. While this will predominantly keep most of the precipitation well to the north and west of the region, there will be a chance for showers and thunderstorms along the eastern edge of the Blue Ridge and points east into the Piedmont on Saturday. With the repeated rounds of showers and thunderstorms across the area, these storms will continue to lead to a localized flash flood threat. This will be especially true given storm motions will continue to be on the slow side of around 5-15 knots. High temperatures will climb into the low 90s across the Piedmont, and low to mid 80s west of the Blue Ridge. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... As of 1210 PM EDT Friday... Key Message: - Hot and humid through the weekend, with daily chances of afternoon showers and thunderstorms. A cold front is expected to stall along the Mason-Dixon line on Sunday, then return northward as a warm front on Monday. With the area remaining in the warm sector, hot and humid conditions will continue along with afternoon and evening showers and thunderstorms. Scattered storms each afternoon will be disorganized, but a few may become strong to severe with the primary threats being damaging wind gusts and localize flooding. High temperatures each afternoon will peak in the 80s across the mountains to the low to mid 90s in the foothills and Piedmont. Dew points will continue to run high, ranging from the mid 60s to lower 70s. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 1210 PM EDT Friday... Key Messages: 1. Thunderstorms Tuesday into Wednesday. 2. Slightly cooler and drier Wednesday and Thursday. A cold front will move from the Ohio Valley Tuesday morning to the VA/NC coast Wednesday morning. This front will bring an organized line of convection across the area Tuesday afternoon and evening. Dry and cooler high pressure will follow the frontal passage Wednesday and Thursday. Another front will slide across the region Friday, but with limited moisture, showers and thunderstorms will be sub-severe. High temperatures will ranging in the 80s Tuesday, then cool down a couple of degrees on Wednesday. Temperatures will gradually warm each day, ending the workweek in the mid 80s to mid 90s. && .AVIATION /23Z FRIDAY THROUGH WEDNESDAY/... As of 700 PM EDT Thursday... Scattered storms may impact ROA/LYH/DAN/BCB this evening but most of the period into midday tomorrow will be dry. Outside of storms expect VFR. Stratus/fog will be possible again tonight where it rained and across the river valleys. LIFR at LWB appears likely and could see MVFR to IFR at the other terminals, both vsby and cigs. Any fog and low clouds will erode by 12-15z Saturday slowest at LWB. Storms will again fire up by 17-18z, mainly in the mountains so have VCTS in the afternoon at BLF/LWB/BCB. EXTENDED AVIATION OUTLOOK... High pressure should maintain VFR conditions into early next week outside of any storms and late night/early morning fog. A front tracking in by Tuesday will bring a better coverage of storms and better chance of sub-VFR. This front should lead to VFR conditions through the end of next week outside of any river valley fog that may develop near BCB and LWB. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...Flood Watch until 11 PM EDT this evening for VAZ011-013-014- 018>020-022>024-033>035-045-046. NC...None.
