554 FXUS61 KRLX 011625 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 1225 PM EDT Mon Jun 1 2026 .WHAT HAS CHANGED... 18Z TAF discussion... No significant changes from previous forecast. && .KEY MESSAGES... 1) An extended period of quiet weather is forecast this week. The next widespread chance of rain will not be until later this weekend or early next week. && .DISCUSSION... KEY MESSAGE 1... 500-mb energy will transfer from the Great Lakes to the Carolina coast Tuesday with the development of a coastal low. This energy transfer may trigger light shower activity across the West Virginia mountains, only yielding 0.10 to 0.20 inch of precipitation. Otherwise, most of the week looks dry with omega high pressure in control over the middle Ohio Valley and Appalachians. With high pressure in place, each night will be mostly clear, cool, and calm with patchy fog developing in the river valleys. Fog will become less frequent by Thursday and Friday as the ground and atmospheric boundary layer progressively dry out each day. The next area-wide chance of rain will be late Saturday into Sunday, but even that is highly uncertain. Some models, like the GFS, show an upper-level low developing over the Great Lakes and Northeast during this timeframe, reintroducing rain chances. In contrast, other models, like the ECMWF, keep a ridge of high pressure in full control over the eastern states through the entire weekend. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... Mainly VFR conditions with light winds are expected throughout the period. Some patchy IFR fog can be expected at KCRW and KEKN between 09Z and 13Z Tuesday. Any fog that does develop should dissipate quickly after sunrise with VFR returning. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: Extent and duration of fog may vary from the forecast.
