FXUS61 KRNK 211052 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 652 AM EDT Mon Sep 21 2026 .WHAT HAS CHANGED... No major changes to the forecast, just removing thunder from Wed-Thu for most of the area with a strong wedge and changing from showers to rain. Aviation updated. && .KEY MESSAGES... 1) Unsettled weather expected through midweek as a front meanders around the area. Turning cooler midweek. && .DISCUSSION... KEY MESSAGE 1: Unsettled weather expected through midweek as a front meanders around the area. Turning noticeably cooler by Wednesday. Looking at frontal boundary across our area today, with several vorts moving along it aloft and should see a decent shot of showers/storms by late this afternoon and especially tonight into Tuesday. The front drops south Tuesday into Wednesday while we get wedged in. Today will be the last warm day, and depending on how much sunshine we get, could see some stronger storms develop, but again looks isolated. As far as heavy rain/localized flooding, there will be a potential for that, with the 00z HREF probabilities for more than 3" rain in 12 hrs highlighting the Piedmont of NC tonight. Still models/ensembles are blotchy with this coverage and not seeing a need for any flood watches. As we head into Tuesday, will have to watch where the heavy rain occurs today-tonight, and whether we may need flood watches. The bigger story will be the significant cool down with potential to remain stuck in the 50s and 60s Wednesday and Thursday. Cold air advection is expected to persist for multiple days so it may take until the weekend to return to readings near normal. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... Look for mainly VFR starting this morning except some LIFR to IFR conditions at LWB. A few showers may sneak into LWB through 14z. Better coverage of showers/storms arrives this afternoon but again still looking at scattered so VCTS in tafs with mainly VFR. This evening coverage of rain increases with frontal boundary draped across the area. Expect the 00z-06z time frame to be the rainiest especially along east of the BCB/ROA line. Should have IFR or lower conditions during the night so not a good night to fly and this will be the case into 12z Tuesday. Forecast confidence is moderate, but lower on thunderstorm timing Monday. EXTENDED AVIATION OUTLOOK... Rain chances are high for Tuesday as well, with numerous to widespread coverage. During this time expect periods of sub-VFR conditions and potential heavy rain. Fog at night can also be expected, especially in the mountain valleys. For the latter half of the week, gusty north winds are expected per forecast of strong cyclone developing off the New England Coast. Depending on location of this system will determine if we clear out by Friday but looks like we will, with poor flying weather Wed-Thu. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ DISCUSSION...PM/WP AVIATION...AS/PM/WP
