...THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF NORTHERN/EASTERN
OK AND SOUTHEAST KS INTO MO...

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE CENTRAL/SOUTHERN
PLAINS TO THE MIDWEST/UPPER MS VALLEY...

...SOUTH-CENTRAL PLAINS TO MIDWEST/UPPER MS VALLEY...
A SCATTERED SUPERCELL OR TWO REMAINING CAPABLE OF A STRONG TORNADO
WILL REMAIN A DISTINCT CONCERN ESPECIALLY OVER THE NEXT FEW HOURS
/MID INTO LATE EVENING/ ACROSS EAST-CENTRAL/NORTHEAST OK...WITH
ADDITIONAL DEVELOPMENT INCLUDING SUPERCELLS ALONG A CONSOLIDATING
NORTHEAST-SOUTHWEST ORIENTED FRONTAL ZONE ACROSS KS INTO NORTHERN
OK.

MEANWHILE...TO THE NORTHEAST...MULTIPLE AMALGAMATING/UPSCALE GROWING
CLUSTERS WILL LIKELY CONTINUE TO EVOLVE ACROSS THE OZARKS/LOWER MO
VALLEY INTO THE MIDDLE/UPPER MS VALLEY. THE MOST SUBSTANTIAL UPSCALE
DEVELOPMENT/SUSTAINED LINEAR ORGANIZATION WILL LIKELY IMPACT THE
LOWER MO VALLEY/MIDDLE MS VALLEY TONIGHT...ESPECIALLY GIVEN
NOCTURNAL STRENGTHENING OF AN ALREADY MODERATELY STRONG SOUTHERLY
LOW LEVEL JET. POTENTIALLY WIDESPREAD DAMAGING WINDS WILL BE A
CONCERN ESPECIALLY ACROSS MO INTO EASTERN IA/FAR WESTERN IL...WITH A
FEW TORNADOES /POSSIBLY EVEN A STRONG ONE/ POSSIBLE IN ASSOCIATION
WITH EMBEDDED MESOVORTICES.
