694 FXUS63 KPAH 151836 AFDPAH Area Forecast Discussion National Weather Service Paducah KY 136 PM CDT Sat Jun 15 2024 .KEY MESSAGES... - Triple digit or close to it heat index Sunday-Monday, and again heading into next weekend. - Daily storm chances Monday thru Wednesday. && .DISCUSSION... Issued at 135 PM CDT Sat Jun 15 2024 The 1 PM dew point is 51F in Wayne City, IL, but 72F in Poplar Bluff, MO. Visible satellite shows a diurnal cu field mostly in conjunction with the higher dew points over WKY/SEMO. These will disperse with sunset/loss of fuel. The mean upper ridge moves east with time. Higher temps/dew points will be realized beginning tmrw and lasting into the new work week. The ridge is strongest Sunday-Monday with 590+ DM heights at H5. Dew points close to 70F and high temps well into the 90s both days means Heat Indices near or into the triple digits, but looks just shy of headline 105s at this writing. The only relief will be from the daily heat of day storm chances in the high instability, low shear environ. The high pushes further east by mid week, as a low pressure storm system approaches from the west. Good return flow here/in between means more pops/clouds Tuesday-Wednesday, which gives a temporary reprieve with highs in the 80s and a continued daily chance of showers/storms. The high retrogrades its ridge anchor thereafter, resulting in a drier and warmer back half of the week. We`re looking at highs again in the mid to potentially upper 90s and heat indices possibly around the century mark again. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 135 PM CDT Sat Jun 15 2024 4-6K FT AGL bases may be SCT-BKN at times, esp over the southern half of the FA, as drier air has more fully worked down the column in the north. Loss of diurnal fuel will see their disperson with the setting sun, as winds go light. Return flow southerlies initiate tmrw, and time/height cross sections support diurnal cu again in the 4-5K FT AGL range. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...Air Quality Alert from midnight CDT /1 AM EDT/ tonight to midnight CDT /1 AM EDT/ Sunday night for INZ081-082- 085>088. KY...None. && $$
