UPDATE

Issued at 740 PM EDT WED MAY 6 2026

23Z sfc analysis shows a cold front settling southeast through eastern Kentucky this evening. Showers and patches of drizzle follow this boundary with a gradual drying trend ensuing from northwest to southeast. Currently, under plenty of low clouds, temperatures are running in the low to mid 50s through the area. Meanwhile, amid northwest winds of around 5 mph, drier air is inbound from the northwest where dewpoints are generally in the low to mid 40s while low and mid 50s are noted to the southeast. Have updated the forecast mainly to add in the latest obs and trends for the T/Td/Sky grids while tweaking the PoPs per the current radar and CAMs guidance. Did also take out the thunder chances for the rest of the night. These adjustments have been sent to the NDFD and web servers along with a freshening of the HWO, SAFs, and zones.

LONG TERM

(Friday through Wednesday) Issued at 431 PM EDT WED MAY 6 2026

An upper level low over Hudson Bay and its associated cyclonic flow will allow for mean troughiness for most locations east of the Rockies through the weekend. The low will then generally migrate eastward into early next week, with northwest flow aloft being reinforced across the northern half of the CONUS, although model details remain more uncertain. This will result in periodic rain chances across eastern Kentucky, with temperatures moderating back to above normal this weekend, and then cooling off to below normal into early next week.

High pressure will start off positioned across the southern Appalachians early Friday. This feature will quickly move east, allowing for return flow across eastern Kentucky. Temperatures will rebound into the upper 60s to lower 70s. A short wave trough and surface cold front will take aim at the Ohio Valley Friday night, with our eastern valleys dropping off into the upper 40s early on, before thicker clouds invade after midnight. Other locations will remain in the 50s. Rain chances will increase from the northwest after midnight, mainly north of the Mountain Parkway. Better upper level support will remain to our north, generally exiting by Saturday. The cold front will move through eastern Kentucky on Saturday, supporting small chance PoPs.

Another brief period of drier weather moves in for Saturday night, before better chance PoPs return Sunday into early Monday, although the GFS and ECMWF remain at odds with the details. Depending on the solution, rainfall totals could range from around a tenth of an inch to as much as a half inch. High pressure and dry weather take hold from Monday night through Tuesday afternoon, before yet another system approaches our area from the northwest, bringing the next chance of rain, mainly Tuesday night into early Wednesday.

Highs will warm through the 70s by Sunday, before retreating to the 60s on Monday. Temperatures will then warm back to near normal readings by Wednesday, with highs in the mid to upper 70s. Lows will be in the 40s and 50s, with Tuesday morning likely the coolest day, with a few locations dipping to below the 40 degree mark perhaps.

With this pcpn, MVFR to IFR ceilings and visibilities are prevalent and will likely stay that way through the rest of the night. Conditions will then improve rapidly after 14Z, at most locations, into the VFR category. Winds are generally under 5 knots from the northwest - becoming light and variable tonight and staying that way on Thursday. There could also be periods of patchy fog overnight - generally after 06Z.
