FXUS63 KPAH 030712 AFDPAH Area Forecast Discussion National Weather Service Paducah KY 212 AM CDT Thu Jul 3 2025 .KEY MESSAGES... - Dry and mostly sunny conditions will continue today through the first half of the holiday weekend. - Increasing heat and humidity can be expected for the 4th of July and through the weekend. - Chances of showers and thunderstorms will return Sunday afternoon, with an unsettled weather pattern persisting into the middle of next week. && .DISCUSSION... Issued at 212 AM CDT Thu Jul 3 2025 A weak upper level disturbance is moving across the Ohio Valley this morning with a few clouds on satellite imagery. Temperatures have fallen into the upper 60's to lower 70's at discussion time with nearly calm wind. Some patchy fog remains possible through the morning. Upper level ridging begins to build across the plains today before shifting east into the Ohio Valley by the weekend. Dry conditions are expected across the region through the holiday period and the first half of the weekend. Temperatures slowly increase the rest of the week and into the weekend with highs returning to the low to mid 90's. By Sunday upper level ridging begins to break down as lower heights approach from the north and west. A surface high will move east allowing for a return of southerly flow and moisture back into the area. A front will approach from the west before nearly stalling out across the region next week. This front and further support from troughing aloft will bring an unsettled weather pattern to the region. Severe weather chances look low given the lack of shear. PW's rise to around 2-2.1" next week supporting the potential for some heavy rainfall but don't see any signals for a more heightened risk of flash flooding at this time. && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 1144 PM CDT Wed Jul 2 2025 KMVN already has an MVFR visibility in fog and that will continue through the night. They are not likely to fall through the cross-over temperature, so any lower conditions should be shallow. Used MIFG to handle anything less than MVFR. Cannot rule out similar conditions developing at KCGI and KPAH, but KEVV and KOWB should remain VFR. KMVN may drop to MVFR levels again by the end of the period, as well, but will not insert it in the forecast at this time. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
