167 FXUS63 KLMK 081750 AFDLMK Area Forecast Discussion National Weather Service Louisville KY 150 PM EDT Tue Jul 8 2025 ...Updated Aviation Discussion... .KEY MESSAGES... * Scattered thunderstorms could produce locally gusty winds and brief torrential rainfall this afternoon and evening. * Warm and humid all week, with scattered showers and thunderstorms expected each day. Organized severe weather is not expected. && .SHORT TERM /THROUGH TONIGHT/... Issued at 350 AM EDT Tue Jul 8 2025 Radar image continues to show a few isolated showers across central KY here in the early morning hours. Very patchy fog is possible as a few isolated observation sites have seen visibility drop to near 1 mile. Current satellite imagery shows high clouds over central KY which will help keep the threat of fog low. Quasi-stationary boundary will remain north of the Ohio River today into tonight. This will continue to keep us in the warm sector which will mean another warm and muggy day. Temperatures are expected to climb into the mid/upper 80s with dew points in the upper 60s/low 70s. Another day of pop-up showers and storms, mainly in the afternoon. Coverage is once again expected to be scattered with the highest chance of precipitation along and south of the parkways. Torrential rain, thanks to PWAT values around 1.50" will be possible, along with lightning and possible strong gusty winds. Showers and storms will start to taper off as we lose daytime heating after sunset. While a few showers/storms could linger it will be mostly dry with increasing high clouds. Given the cloud cover I think the fog threat looks very low. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... Issued at 350 AM EDT Tue Jul 8 2025 The pattern will continue to feature a general ridging to the west and troughiness across the eastern third of the CONUS. The quasi- stationary boundary will meander mainly north of the Ohio River with daily chances of scattered showers and thunderstorms. Given the placement of the boundary to our north, this will keep us in the very warm and muggy airmass featuring highs in the upper 80s to low 90s and dewpoints in the upper 60s/low 70s. Coverage of any convection each afternoon looks to be scattered in nature with activity diminishing after sunset. The severe threat from any of these storms remains relatively low given the lack of shear preventing much organization. With PWATs remaining high the main threat from these showers and storms will be localized heavy rainfall, lightning and possible strong wind gusts. By the weekend, we`ll be located between two upper level features, an amplifying ridge over the southeastern US, and a strong upper low over the Dakotas. Additional shower and storms chances are expected as we will remain in a warm and humid airmass. Precip chances will peak each afternoon, and diminish for the nighttime hours each day. && .AVIATION /18Z TAFS THROUGH 00Z THURSDAY/... Issued at 149 PM EDT Tue Jul 8 2025 VFR conditions are ongoing across the region this afternoon, with a scattered cu field overhead. A cluster of storms is moving across southwestern KY, which may impact BWG later this afternoon. Otherwise, a few isolated pop-up showers are possible near LEX and RGA, but not confident enough to include a PROB30 group at those terminals. Mid-level clouds will persist overnight, though VFR flight cats are expected tonight and into tomorrow. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...None.
