668 FXUS63 KPAH 251128 AFDPAH Area Forecast Discussion National Weather Service Paducah KY 628 AM CDT Tue Jun 25 2024 .KEY MESSAGES... - Hot and humid today with a Heat Advisory in affect for portions of the area that will see heat indices at or above 105. - Chances for showers and storms mid week bring a brief respite from the heat. Storms will be pulsey in nature but some could be strong to severe, with mainly a wind threat. - Hot and humid again on Saturday with heat indices of 105-110. && .DISCUSSION... Issued at 246 AM CDT Tue Jun 25 2024 A hot and humid day is in store for today with highs in the mid to upper 90s and heat indices of 100 to 115 (SEMO). A Heat Advisory is in effect for portions of the area with heat indices above 105 from Noon to 8 PM today. There is a weak chance for some afternoon convection to develop along an outflow boundary left over from a large MCS that moved through the western Great Lakes. Instability is sufficient to strong but shear is weak, and so storms will likely be pulsey in nature with damaging winds possible with the collapse of stronger storms. Mainly zonal flow aloft yields to a shortwave trof moving through on Wednesday. This will push a cold front through the area and bring with it a little bit of short lived respite from the heat. The best chance for rain is also on Wednesday with more pulse storms possible throughout the day. Confidence in timing and location are low. Some may be strong to severe though with damaging winds the main concern with the collapse of stronger storms. Thursday will be nice, relatively speaking, with less humidity and highs in the mid to upper 80s. This will be short lived however as temperatures climb back into the low to mid 90s on Friday. Saturday will be another hot and humid day with highs in the mid to upper 90s and heat indices of 105-110. The potential for some convection on Saturday could work to dampen the heat threat some. Another front looks to move through Sunday morning with convection chances Saturday and Sunday. Slightly cooler conditions on Sunday and Monday with highs in the upper 80s to lower 90s then hot again Tuesday. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
