982 FXUS61 KRLX 282203 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 603 PM EDT Tue Jul 28 2026 .WHAT HAS CHANGED... The severe weather threat for today has waned and relatively benign weather is expected to set in for tonight. Areas of dense fog will, however, be possible late night into early Wednesday morning. && .KEY MESSAGES... 1) Additional chances showers and some storms will continue into Wednesday for the mountain areas, with drier weather elsewhere through Friday followed by a return of storm chances this weekend. && .DISCUSSION... KEY MESSAGE 1... The shortwave trough, accompanied by a closed low embedded within, will continue to progress slowly eastward over Upstate NY and New England through the end of the work week. Northwesterly flow on the backside of the trough will support a renewed potential for showers in the mountains Wednesday afternoon. Updrafts may struggle to reach heights high enough to produce lightning due to the depletion of CAPE and increasing subsidence aloft; however, lightning cannot be ruled out entirely across the mountains. Otherwise, a refreshing, northwesterly breeze is forecast area-wide Wednesday, with stratocu developing by late Wednesday morning. Dry and warm weather is forecast through Friday, with storm chances forecast to return this weekend due to a shortwave trough digging into the Upper Midwest as the subtropical ridge retrogrades over the Desert Southwest. && .AVIATION /21Z TUESDAY THROUGH SUNDAY/... Precipitation coverage will continue to diminish, becoming confined to a few showers along the mountains this evening into tonight. A mix of MVFR to VFR ceilings are expected amid scattered to broken cloud cover this evening, then conditions should deteriorate to IFR/LIFR as low stratus and valley fog develop overnight. Areas of dense fog are most likely to occur in locations that received rain earlier in the day. Restrictions will gradually improve to VFR Wednesday morning, though some MVFR ceilings could linger into the afternoon along the mountains. Northwest winds will be light overnight, then increase to around 5- 12 kts during the day Wednesday. Gusts to around 15-25kts may also be possible at times, particularly during the afternoon and evening.
