Cannonsburg Ski Area Snow Report

430 FXUS61 KILN 070531 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 131 AM EDT Fri Aug 7 2026 .WHAT HAS CHANGED... No significant changes. && .KEY MESSAGES... 1) Showers and thunderstorms will be possible at times into the weekend and early next week. && .DISCUSSION... KEY MESSAGE 1) Overnight showers and a few thunderstorms continue early this morning as a warm and moist air mass lingers over the Ohio Valley. Additional thunderstorms will form this afternoon as temperatures rise and instability increases. While a few strong wind gusts cannot be ruled out with the tallest storms, weak wind shear and slow storm motions will more likely favor the potential for locally heavy rainfall over any damaging wind threat. As outflow boundaries form from collapsing updrafts, light southerly flow may continue to feed instability northward, enhancing the locally heavy rainfall threat. Both the SPC HREF and REFS give the highest potential for this to occur across southern Ohio, southeast Indiana and northern Kentucky. The threat is not widespread enough to warrant a watch, but areas that receive multiple thunderstorms could see enough rain to cause flooding. There will likely be a lull in thunderstorm activity during the overnight hours, but a trough approaching from the northwest results in additional thunderstorm chances starting Saturday mid-morning and into the afternoon. Activity will shift southeastward throughout the afternoon and into the evening. The big picture jet stream pattern begins to evolve on Sunday, with a stalled boundary lifting northward. Some thunderstorms will be possible, but the overall forcing will be limited by the trough shifting to the east. The best chances for thunderstorms are late in the afternoon and into the evening as peak heating is achieved. Better moisture begins to move back into the Ohio Valley Sunday into Monday. A longwave trough over Hudson Bay in Canada provides a fairly steady period of persistent northwesterly upper level flow over the Midwest and Great Lakes regions. In the lower atmosphere, southwesterly flow will feed moisture northward supporting higher values of instability across the corn belt. As mentioned in SPC`s 4-7 day severe weather outlook, this type of synoptic regime will support the potential for more organized thunderstorm complexes somewhere across the region. Until confidence increases for either day, the finer details on the potential for damaging winds Monday through Wednesday will have to wait. By mid to late week, confidence is increasing that drier air from the trough to the north will shift southward into the Ohio Valley, bringing cooler and drier conditions for the late part of the work week. && .AVIATION /06Z FRIDAY THROUGH TUESDAY/... No major changes from the 00Z TAFs with scattered showers continuing to work through the area. Eventually, additional downpours and some thunderstorms will develop, but there remains some uncertainty as to the ultimate coverage. TEMPO groups remain in place for the higher confidence time periods. Radar trends will be closely monitored for updates to local TAF site timing. While patchy fog cannot be ruled out in between clouds and precipitation overnight, in general expect VFR conditions outside of precipitation through the TAF period. Winds will generally be around 10 knots or less. OUTLOOK...Thunderstorms are possible at times through Tuesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
