AREAS AFFECTED...ERN NEB...MUCH OF IA AND NRN MO

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 252334Z - 260130Z

THUNDERSTORMS MAY INTENSIFY NEXT COUPLE HOURS OR SO FROM PARTS OF
ERN IA AND SPREAD INTO NRN IL. ISOLATED DAMAGING WIND AND HAIL WILL
BE THE MAIN THREATS. WW MAY BE NEEDED FOR THIS AREA SHORTLY.

AN AREA OF WIDESPREAD ELEVATED CONVECTION CONTINUES FROM ERN NEB
THROUGH IA MOVING ESEWD. ACTIVITY APPEARS TO BE ASSOCIATED WITH A
ZONE OF MID LEVEL ASCENT ASSOCIATED WITH AN EWD ADVANCING SHORTWAVE
TROUGH. STORMS HAVE INTENSIFIED ALONG THE ERN PERIPHERY OF THE MID
LEVEL CONVECTION ACROSS ERN IA. ATMOSPHERE DOWNSTREAM IS MODERATELY
UNSTABLE WHERE SURFACE HEATING HAS BOOSTED THE TEMPERATURES INTO THE
UPPER 80S TO AROUND 90. VERTICAL SHEAR PROFILES ARE WEAK AND LARGELY
UNIDIRECTIONAL WSWLY SUPPORTIVE OF MULTICELL STORMS. HOWEVER...THE
THERMODYNAMIC ENVIRONMENT APPEARS SUPPORTIVE OF DAMAGING WIND GUSTS
AS STORMS EVOLVE INTO LINES OR CLUSTERS. SOME HAIL MAY ALSO
ACCOMPANY THE STRONGER CORES.
