.DISCUSSION...
(This evening through next Thursday)
Issued at 213 PM CDT Fri Jun 13 2025

Active weather will remain in place across the Midsouth for much of 
the next 7 days, along with near to above normal temperatures and 
very humid air. 

Afternoon satellite and radar data clearly show the slow moving mid-
level cyclone over SW Missouri. This feature will gradually advance 
east toward the Ohio Valley over the next 12-24 hours. As it does 
so, bands of isolated to scattered showers and thunderstorms will 
progress through the region, slowly moving toward the E/NE. The 
accompanying airmass surrounding the low is characterized by 
abundant moisture with PW values in excess of 2 inches in areas 
along with aoa 35 kts of deep layer shear. The greatest coverage in 
activity will coincide with peak diurnal heating and there could be 
sufficient instability in place for a few storms to become strong to 
possibly severe at times. Main concerns given the parameters in 
place would be damaging wind gusts and locally heavy downpours. 

In the coming days, mid-level weakness will remain in place from 
portions of the Southern Plains into the Lower MS River Valley 
between ridges across the SW and SE US. This will allow occasional 
shortwaves to work their way into the area from NW to SE and with 
each one will come the potential for additional showers and 
thunderstorms. There could be some MCS potential as well, but for 
the time being that threat looks a little greater to the west of the 
forecast area. 

By late week, while it doesn't look completely dry, it appears that 
H500 ridging will gradually fill across the area and begin to expand 
northward. This would likely limit rain chances further and allow 
temperatures to climb. Given Td values in the 70s F, heat indices 
are likely to go above 100 at times. This will correspond to 
frequent Heat Risk levels of moderate to major across the area.

(00Z TAFS)
Issued at 614 PM CDT Fri Jun 13 2025

Scattered thunderstorms will continue to move east across the 
region this evening. Additional thunderstorms are expected for 
later this evening. One final round of thunderstorms will move 
across the Mid-South overnight through Saturday. Current VFR 
ceilings will lower to MVFR levels overnight. Once the 
thunderstorms exit the region on Saturday, VFR conditions will 
return. Winds should be mainly from the south around 5 knots 
through Saturday morning with a shift to the southwest in the 
afternoon.
