Area Forecast Discussion
National Weather Service Springfield MO
613 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 00Z TAFS through 00Z Sunday evening)
Issued at 609 PM CDT Sat Jul 10 2021

Area of most intense convection was located southwest of the
forecast area and is expected to remain southwest of the area.
Additional convection will affect the JLN/SGF/BBG terminals
between 00z and 04z this evening. Will likely see MVFR/IFR within
the convection. Some lower ceilings possible overnight in the
MVFR and possibly IFR. Scattered showers and storms possible on
Sunday with the upper low. Winds will swing around to the
northwest behind the front tonight.
