Area forecast discussion, Jul 10, 3:09 PM CDT, 22 minutes before
Area Forecast Discussion National Weather Service Springfield MO 309 PM CDT Sat Jul 10 2021 .SHORT TERM...(This evening through Sunday) Issued at 245 PM CDT Sat Jul 10 2021 Sfc low near the IA/IL/MO border with a trailing cold front extending back to the west through west central MO into east central KS will begin to shift to the southeast over the next few hours. MCV that brought an earlier round of convection to our area has stabilized some of the area (central MO) but daytime heating is recharging the atmosphere farther to the west with mlcapes values of 2500-3000+ j/kg over eastern KS/western MO. With sfc heating/high dew points, any convective inhibition is expected to gradually erode this afternoon. Should see convection re-fire along the boundary/sfc front toward 20-22z. 0-6km bulk shear of around 40 kts will support supercells and large hail and a brief tornado risk over southeast KS with initial development. As cold pools organize, storms are expected to develop into bowing segments/lines as they drop sse through our area. Best chances for severe storms will be over the southwest half of the cwfa which will have stronger instability, but can't rule it out later farther east as temperatures recover. Strongest storms should move south of the area this evening although some scattered storms will remain possible with an upper level low moving through the area. Sunday will be a cool/cloudy/showery day but with little instability the chances for severe storms looks low/nil. .LONG TERM...(Monday through Saturday) Issued at 245 PM CDT Sat Jul 10 2021 Monday: The upper low/trough axis will remain over the area Monday with cool weather. Can't rule out some afternoon showers over the eastern cwfa. Tuesday: Will see a warming trend as the upper trough finally shifts east. Wednesday-Thursday: Another shortwave moving through the northern Plains and Midwest will support a sfc cold front that will sag southeast into the area and stall over IL/MO/KS as a west-east boundary by late Thu/Thu night. Will see increased chances for storms during this time. Friday-Saturday: Weak zonal flow aloft in the wake of the shortwave and left over frontal boundary will support pulse type convection, typical July weather. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1243 PM CDT Sat Jul 10 2021 KSGF/KJLN/KBBG tafs: Area of showers/storms is moving off to the east of the taf sites with some vfr ceilings in it's wake. Additional storm development with MVFR/IFR conditions in heavier rain is expected near/ahead of a cold front that will move sse through the region 22z-02z. Will see some post frontal lower ceilings with an upper low moving in behind the front with continued occasional showers/tstms at times. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.

Weather hazards expected... Limited tornado risk. Limited hail risk. Elevated thunderstorm wind damage risk. Limited flooding risk. Significant lightning risk. Limited excessive heat risk. DISCUSSION... Scattered thunderstorms will continue this morning across central Missouri, or locations along and north of Highway 54. Severe weather is not expected with this activity however lightning, gusty winds and brief heavy rainfall are possible. More intense thunderstorms may develop as early as mid afternoon across southeast Kansas into western Missouri.

Frequent cloud to ground lightning is likely. Locations south of a Pittsburg Kansas to Springfield to Gainesville line have the highest potential for severe weather. Locally heavy rainfall and flash flooding will be possible this evening, especially in the more flood prone areas of the Ozarks. Widespread flooding is not expected at this time. Afternoon heat index values in the middle 90s are possible across far southern Missouri this afternoon. .DAYS TWO THROUGH SEVEN...Sunday through Friday.
