952 FXUS61 KRNK 282338 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 738 PM EDT Sun Jun 28 2026 .WHAT HAS CHANGED... Aviation updated. && .KEY MESSAGES... 1) Probability of showers and storms will decrease by Tuesday. Still a few heavy rains, potential strong storms this afternoon mainly in southside VA into the NC piedmont. 2) Hot and humid conditions will occur Wed-Sat. && .DISCUSSION... KEY MESSAGE 1...Shower and storm coverage lessens into early week. Still a few strong storms/heavy downpours this afternoon mainly in NC into southside VA. Debris clouds from upstream overnight convection has put a lid on instability in the mountains and north of the VA/NC border. Some sun is allowing for SBCAPEs to reach 1000-1500 J/kg in the south. This would be the area to watch for any strong storm development. So far radar trends are mainly showing lower topped heavy rainers with limited if any lightning. Better severe convective potential will be south of I-40 in NC toward the SC border. Will have to watch for localized flooding as PWATS running from 1.7 to 2 inches west to east, especially in training cells. Showers start to fade as front works south tonight but atmosphere remains highly moist, so cannot rule out isolated showers, or even drizzle along the Blue Ridge. Monday looks like less coverage but another upstream shortwave on the east side of the ridge could lead to widely scattered storms in the afternoon. KEY MESSAGE 2...Hot and humid conditions will occur during the latter half of this week. A broad upper level ridge should build northeastward towards the Ohio River Valley between Monday and Wednesday. This ridge could become centered overhead by Thursday and Friday. While chances of showers and thunderstorms should lessen due to capping aloft, the bigger impact will be the increasing heat and humidity. Temperatures should jump notably after Tuesday with highs in the 90s for most locations and even a few lower 100s east of the Blue Ridge for the remainder of this week. Heat indices could reach up to 105 degrees across the Piedmont. There may be upper level troughing across southeastern Canada that could start to gradually weaken the ridge towards the end of this week, but Independence Day looks to stay hot and humid. Make sure to have plenty of water and sunscreen, and check your air conditioners to ensure that they are working properly. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... Shower activity should wane as we progress through the evening and early overnight hours. However, for much of the region overnight and into early Monday morning, we are expecting sub- VFR cigs and vsbys with stratus and mist/fog. Conditions improve to VFR for the entire area by the late morning. Winds will be light and variable or calm through the night, and stay that way, or trend light east, through the day Monday. Isolated showers and storms will be possible generally along a KHSP to KMWK line tomorrow afternoon/evening. Some of the stronger ones could yield some brief and localized sub-VFR conditions. EXTENDED AVIATION OUTLOOK... Cannot rule out some isolated showers/storms the rest of the week, but the upcoming week will feature high pressure and mainly VFR conditions, outside any late night fog. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ DISCUSSION...PW/WP AVIATION...DS/WP
