375 FXUS61 KRNK 180130 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 930 PM EDT Mon Aug 17 2026 .WHAT HAS CHANGED... Severe Thunderstorm Watch #590 has been cancelled for our North Carolina Counties. && .KEY MESSAGES... 1) Convection will remain possible overnight ahead of an eastward-moving cold front. 2) Dry weather returns Tuesday, with the next rain chances forecast Thursday through Saturday. && .DISCUSSION... KEY MESSAGE 1... Convection will remain possible overnight ahead of an eastward- moving cold front. Most of the showers and thunderstorms associated with this afternoon`s convective complex have weakened and/or moved south and east of our area. Because of this, I`ve gone ahead and cancelled Severe Thunderstorm Watch #590 for our counties in North Carolina. We still could see some isolated showers or thunderstorms through the rest of the night, though, as a cold front moves east across the Mountain State and into our area. Even though I can`t rule out some "rogue" showers or storms ahead of the front (reference radar image at 9:30 p.m.), the overall convective coverage should be limited to areas in vicinity of the front. This is due to better forcing and slightly better moisture convergence along the boundary. Timing of the front brings it toward the Blue Ridge around 2 a.m. and pushes it south and east of our our forecast area around 8 a.m. Tuesday. Give-or-take. KEY MESSAGE 2... Dry weather returns Tuesday, with the next rain chances forecast Thursday through Saturday. Behind the passage of a cold front on Monday, drier air is expected to advect into the region. This will lead to significantly reduced shower and thunderstorm chances, with near zero chances forecast Tuesday and Wednesday for the area. An upper level trough and additional cold front pushes into the area late Thursday, which looks to bring shower and thunderstorm chances back into the region. Temperatures also look to return to seasonal values as this upper level trough effectively returns the upper level ridge back west into the western Conus by the end of next week. The aforementioned frontal boundary does look to get hung up across the region through Saturday, leading to scattered rain and thunderstorm chances daily starting Thursday once again. && .AVIATION /01Z TUESDAY THROUGH SATURDAY/... Lowered CIGs/VSBYs will remain possible overnight IVOF ISOLD- SCTD SHRA/TSRA ahead of an E-moving cold front. The greatest coverage of convection will largely be in NC this evening (associated with this afternoon`s convective complex). Additional SHRA may be seen along the front overnight, primarily across SE WV terminals, with some BR/low St. IFR-MVFR level restrictions will be likely primarily W of the Blue Ridge. Restrictions should lift by mid-morning Tuesday, with VFR flight categories expected for much of the day. W winds should veer to a more NW direction, with most speeds around 10 kts. with occasional morning gusts. OUTLOOK TUESDAY NIGHT THROUGH SATURDAY... Tuesday night- Wednesday night: Possible late night CIG/VSBY restrictions due to BR/low St. Otherwise, VFR expected. Thursday-Saturday: Possibility of seeing SHRA/TSRA returns. Restrictions possible IVOF convection, as well as overnight with BR/low St. && .HYDROLOGY... Showers and thunderstorms were pretty anemic across the (former) Flood Watch area this afternoon. Based on this, and the anticipated return to drier conditions over the next few days, I`ve cancelled the Flood Watch. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ DISCUSSION...DB/SH AVIATION...DB HYDROLOGY...DB
