AREAS AFFECTED...ERN KS...NWRN MO...SRN IA

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 182043Z - 182245Z

ISOLATED SEVERE HAIL AND/OR WIND WILL REMAIN POSSIBLE OVER THE NEXT
SEVERAL HOURS BUT A WW IS NOT ANTICIPATED.

STORMS HAVE INTENSIFIED ACROSS ERN KS/NWRN MO WITHIN DEEP MOIST
PLUME AND LIKELY AIDED BY SUBTLE LEAD WAVE ALOFT. HIGH PRECIPITABLE
WATER VALUES HAVE BEEN MEASURED WITH GPS SENSORS INDICATING IN
EXCESS OF 1.80 INCHES. ALTHOUGH SHEAR VECTORS ARE NEARLY PARALLEL TO
CURRENT STORM ORIENTATION...ENTIRE SYSTEM WILL CONTINUE TO TRANSLATE
EWD INTO A RELATIVELY WARM AND DRY AIR MASS. GIVEN HIGH PRECIPITABLE
WATER CONTENT WITH THESE STORMS ALONG WITH DEEPLY MIXED BOUNDARY
LAYERS DOWNSTREAM...A FEW DAMAGING WIND GUSTS WILL REMAIN POSSIBLE.
HAIL THREAT MAY DECREASE WITH TIME AS MOST UNSTABLE AIR GETS
OVERTURNED AND STORMS BECOME UNDERCUT BY OUTFLOW.
