979 FXUS63 KEAX 311912 AFDEAX Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 212 PM CDT Thu Jul 31 2025 .KEY MESSAGES... - Wildfire smoke may move into northern MO this evening/tonight. - Below normal temperatures with lower humidity continue through the weekend. - Temperatures trend near to above normal by the middle of next week with increased humidity building as well. && .DISCUSSION... Issued at 212 PM CDT Thu Jul 31 2025 Upstream observations show smoke/haze with minor visibility restrictions across IA and now into NE MO. This may continue to concentrated enough as it advects southeastward to be noticeable for folks across northern MO. Available guidance indicates this smoke becomes less concentrated the further southeast it advects. Have added mention of this to the grids, which keep it across northern MO. It`s possible this moves further southeast and affects eastern KS and west central MO as well. Guidance also shows another area of smoke moving into the area from the north to northwest tomorrow. This will be higher- level smoke and some mention of this may be needed with future updates. A cooler and much drier airmass will continue to filter into the region as high pressure builds into the Upper Midwest and the Great Lakes area. This will keep our low-level winds from roughly the northeast. The surface high will persist in that region through the weekend, keeping the cooler and drier airmass present through the weekend. This will result in temperatures roughly 10 degrees below normal for this time of year. Dewpoints will also drop into the 50s and lower 60s. Towards the end of the weekend and into next week, as the Great Lakes high pressure shifts further east, low-level flow will become more southeasterly, helping to start some warm and moist advection. This will lead to a start of a warming trend Monday. This modest warm and moist advection, combined with the upper ridge strengthening over the Rockies, increased northwesterly flow, and increasing potential for a few shortwaves to move over the ridge, will bring low chances for precipitation into eastern KS and western MO. Tuesday - Thursday: The upper ridge will continue to build and also expand eastward into the middle of the country for the later half of next week. This will result in temperatures trending upward through the end of the forecast. Current forecast has highs climbing to near to just above seasonal normals. Thursday into Friday, low probabilities of temperatures 95+ spread into eastern KS and western MO. The building of the ridge further east into the middle of the country should also limit precipitation chances. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1210 PM CDT Thu Jul 31 2025 MVFR ceilings currently, with cloud bases around 2-3K feet AGL will increase into the VFR range. Conditions will likely stay VFR through the forecast from there. However, upstream visibility through IA and IL is being reduced to MVFR conditions due to smoke. This may advect into eastern KS and western MO. So we`ll need to monitor the progress of that and add to or amend the forecast. Otherwise, light northeast winds are expected through the forecast. && .EAX WATCHES/WARNINGS/ADVISORIES... MO...None.
