668 FXUS61 KRNK 231646 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 1246 PM EDT Sun Aug 23 2026 .WHAT HAS CHANGED... Aviation Forecast Updated. && .KEY MESSAGES... 1) Drier cooler weather remains through the middle of the week, with next rain chances returning Thursday. && .DISCUSSION... KEY MESSAGE 1: Drier cooler weather remains through the middle of the week, with next rain chances returning Thursday. High pressure and upper level troughing will remain over the eastern Conus through the middle of this upcoming work week. This will keep temperatures slightly cooler than average through the Tuesday of this week. By Wednesday, the upper level trough looks to finally get ejected to the northeast, which will raise 500mb heights across the region briefly. As this happens, the surface high pressure that looks to remain quasi- stationary across the region through Tuesday will slowly push east and allow the Bermuda surface high to take over. This will pump more moisture back into the region from the western Atlantic, and return the summer like humid airmass areawide by Wednesday. Again on late Wednesday, an upper level shortwave vorticity maxima looks to eject southeastward through the northern Great Lakes region. This shortwave looks to have a cold front associated with it at the surface that will bring rain chances back into the region by Thursday afternoon and evening. It`s too soon at this time to know whether these storms will bring the chance for severe weather or flash flooding, as this will greatly depend on the timing associated with the passage of the aforementioned cold front. && .AVIATION /18Z SUNDAY THROUGH THURSDAY/... VFR conditions are expected for a majority of the TAF period at all terminals, with possible brief periods of MVFR to IFR CIGs and VSBYs developing at LWB and BLF during the early morning hours Monday. These restrictions should quickly dissipate after sunrise given the dry airmass in place. Outside of those brief possible early morning fog and low clouds, there are no other restrictions expected. Winds will continue to remain out of the west/northwest through the TAF period, with sustained winds of 5-10 knots and gusts up to 20 knots expected through the afternoon and evening today before becoming calm overnight. Again on Monday winds look to pick up to 5-10 knots sustained, with gusts of only 10-15 knots forecast. OUTLOOK... Drier airmass will sink into the area today and remain into the middle of next week. Should be mainly VFR aside from any late night fog, mainly KLWB. Next system appears to bring some chances for storms Thursday with possibility for sub-VFR cigs/vsbys. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
