Area Forecast Discussion National Weather Service Springfield MO 1209 PM CDT Fri Aug 12 2022 ...18Z AVIATION UPDATE... Key Messages: 1. A warming trend is expected through the weekend with little to no rain chances. 2. Chances for showers and thunderstorms will increase by Monday and continue through Tuesday night. 3. Cooler temperatures are expected for middle and latter part of next week. .SHORT TERM...(Today through Sunday) It was a fantastic night over extreme southeast Kansas and the Missouri Ozarks. Temperatures cooled into the 60s within an airmass containing low humidity. A fairly strong surface high pressure center was located over the Great Lakes region, helping to force easterly breezes through the Ozarks at the surface. This pressure pattern kept the more humid Gulf airmass south of Interstate 40. For today, another peach of a day is expected with highs in the upper 80s and lower 90s. A few locations near Joplin and Columbus could reach the mid 90s, however, dew points in the 50s and low 60s will persist, allowing for more comfortable weather than what we've observed the past few weeks. For tonight, surface winds will return from the south to southeast allowing for more of a mixed airmass. This will keep temperatures a bit warmer into the lower 70s for most areas. The warming trend will continue into Saturday and Sunday as well, with highs ranging from the low to and upper 90s both afternoons. Joplin may hit the lower 100s on Sunday. .LONG TERM...(Monday through Thursday) The summertime high center will gradually settle over the High Plains of west Texas by early next week. Meanwhile, shortwave energy helps force a back door surface front into the ozarks early Monday. This feature will become a focus for showers and thunderstorms starting either Monday or Monday night. This activity will continue into Tuesday night, bringing solid chances for much needed rain across the Ozarks. 27 out of 30 of the GEFS ensemble members all show measurable precipitation by Tuesday PM. Models have been consistent with completely breaking down the summertime high, bringing an extended period of cooler temperatures into the region that could last through all of next week. As of now, we could see highs ranging from the upper 70s to upper 80s on a daily basis Tuesday through Thursday. Some locations may experience overnight lows in the upper 50s. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1209 PM CDT Fri Aug 12 2022 VFR conditions are expected through the TAF period. Could see a few ceilings around 5000 ft approach the TAF sites into this evening. Surface winds will remain generally under 10 knots out of the southeast going variable at times. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
