261 FXUS63 KPAH 201705 AFDPAH Area Forecast Discussion National Weather Service Paducah KY 1205 PM CDT Thu Jun 20 2024 .KEY MESSAGES... - Sunday will bring the most heat, humidity, and best storm chances heading into the weekend. - Wednesday will then offer the next best chance of the same for next week. && .DISCUSSION... Issued at 215 AM CDT Thu Jun 20 2024 High pressure at both the surface and aloft builds in bascially overtop our Forecast Area into the weekend. The result will be daytime high temperatures in the lower to middle 90s, with heat indices 95-100 degrees. While the chance of a daytime shower/storm is not zero, it`s 10% or less, and effectively silent in the forecast, through Saturday. A cold front approaches late Saturday night, and makes its passage Sunday. With its parent low north of the Great Lakes, the system`s energy translates mostly into/across the Middle and Upper Ohio Valley. Nevertheless, the boundary`s presence will see us with a 20-30% pop until it clears the area. Drier dew points work in on the post frontal northerly component (NW-N) winds. Despite the one day reprieve (Monday) from higher dew points, we`ll still heat up again into the low-mid 90s. Another, similar frontal passage is modeled to occur again by mid week. It brings our next best chance of storms Wednesday. Similar to the early week fropa, high temperatures average in the 90s both before and after this 2nd front`s passage too. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
