Area Forecast Discussion National Weather Service Springfield MO 1236 PM CDT Sat Aug 20 2022 Key Messages: 1. Scattered showers and thunderstorms through this evening, with a low chance for a few isolated strong to severe thunderstorms. 2. Seasonable temperatures and mostly dry through much of next week. .SHORT TERM...(Today and tonight) Issued at 230 AM CDT Sat Aug 20 2022 A cluster of showers and a few thunderstorms will continue to slide through the area this morning along a weak cold front. Much of this activity is focused north of Interstate 44 early this morning. Expect this activity to sink south along the frontal boundary through the late morning into the afternoon. For this afternoon, expect afternoon highs in the middle to upper 80s. Modest instability and shear are forecast in the wake of diurnal heating in a moist low-level airmass. This may support the potential for a few isolated strong to severe thunderstorms. The strongest of the thunderstorms will support damaging wind gusts up to 60 mph and hail up to the size of quarters. Lightning and brief heavy downpours can be expected within any thunderstorms. Overall, the environment remains modest at best with storm coverage remaining limited. Some locations may remain completely dry through tonight. For tonight, precipitation chances subside overnight into early Sunday morning. Clouds clear the region through the afternoon on Sunday, leaving behind a pleasant Sunday with afternoon highs in the middle 80s. .LONG TERM...(Monday through Friday) Issued at 230 AM CDT Sat Aug 20 2022 Looking ahead to next week, seasonable temperatures and mostly dry weather will headline the forecast. Seasonable daily highs in the the middle to upper 80s, with a few locations in the low 90s across southeast Kansas and southwest Missouri. Overnight lows in the 60s are likely. This will be accompanied by minimal rain chances through the week. WPC Cluster Analysis suggest low end chances possible by the late week, though considerable ensemble differences exist during this time period. Precipitation chances will continue to be monitored. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1229 PM CDT Sat Aug 20 2022 For the 18z TAFS, a frontal boundary will be the focus for some scattered convection this afternoon and evening over the area. Coverage not expected to be all that great, so will go with VCTS wording. Used some prob30 wording at JLN after 03z. Outside of convection, we are expecting VFR conditions, but may have some MVFR within convection and potentially some brief IFR. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
