Issued at 243 PM CDT Sat Sep 20 2025 A few storms will continue to move southeast along and southwest of a Neosho to Cassville, Missouri line this afternoon. Lightning and brief locally heavy rainfall will be the main risk with the storms. Elsewhere remains dry across the area this afternoon behind the shower and storms that moved through the area earlier this morning. An isolated shower or storm may be possible across the rest of the area this afternoon but much of the area should remain dry as a cap has developed and the better lift moves off to the east. An upper level trough will move east across the central plains this evening into tonight and across the area on Sunday. Uncapped MUCAPE will develop and spread east across the area this evening and tonight as a low level jet also develops and move east across the area ahead of the trough. Uncapped MUCAPE of around 1000 to 1800 J/kg will develop this evening as the deep layer shear around 20kts. Lift within the low level jet and ahead the trough combined with the uncapped MUCAPE will result in scattered storms developing as early as 5pm this evening and could linger into the overnight hours. With the the low level jet and advection convection may redevelop over areas that where affected by early storms which could lead to a localized flooding risk. A few of the stronger storms could be capable of small hail and wind gusts of 30 to 40 mph. Overall the storms will be scattered in nature but there could be an area will multiple storms develop close to each other and develop into a small storm complex this evening and moves off to the southeast overnight with a localized flooding risk the main risk. Storms may be ongoing across parts of the area Sunday morning, but should start to dissipate by mid to late morning. Additional storms are then expected to develop mid Sunday afternoon into the evening hours. Locally heavy rainfall will be the main risk with the storms on Sunday but a few of the stronger storms could have wind gusts up to 40 mph and small hail.

Issued at 243 PM CDT Sat Sep 20 2025 An active weather pattern will remain over the region next week as a sires of upper level troughs move through the region bringing shower and thunderstorm chances to the area at times with the passage of each trough. The first wave will move through the region later Monday into Tuesday, some scattered storms will be possible during the day Monday but a complex of storms could develop across the plains and track southeast into portions of the area late Monday into early Tuesday. Some gusty winds could be possible if any line segments can develop within this activity and can track into the area. The troughs will also bring seasonable temperatures to the area next week as highs the ensemble model members are in fairly good agreement of highs the middle 70s to the lower 80s. There will be breaks in the rain and some days the rain may be more scattered in nature. the models are in fairly good agreement with the trough early next week but start to differ some on the timing and track of the troughs mid to late next week. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 619 PM CDT Sat Sep 20 2025 For the 00z TAFS, expecting convection to refire over the area as the low level jet starts to increase into the region early this evening. JLN/SGF/BBG will all have the potential for some thunderstorms which may limit flight categories to the MVFR and possibly some IFR within the convection. Additional convection will then be possible on Sunday afternoon. && .SGF WATCHES/WARNINGS/ADVISORIES... KS...None. MO...None. && SHORT TERM...Wise LONG TERM...Wise AVIATION...Lindenberg
