AREAS AFFECTED...ERN AND SRN IA THROUGH NRN MO

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 061934Z - 062130Z

THUNDERSTORMS ARE EXPECTED TO CONTINUE DEVELOPING OVER ERN IA AND
EXPAND SWWD WITH TIME INTO SRN IA AND PARTS OF NRN MO. THE STRONGER
STORMS WILL BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WIND
GUSTS. AREA WILL CONTINUE TO BE MONITORED FOR A POSSIBLE WW.

STORMS HAVE INTENSIFIED OVER ERN IA ALONG PRE-FRONTAL CONVERGENCE
BOUNDARY. OTHER STORMS HAVE INTENSIFIED OVER SERN IA ALONG OUTFLOW
BOUNDARY THAT EXTENDS FROM CNTRL IL NWWD INTO SERN IA. THE
ATMOSPHERE CONTINUES TO DESTABILIZE IN A NARROW AXIS NEAR AND S OF
THESE BOUNDARIES AS TEMPERATURES CLIMB INTO THE MID 80S WITH
DEWPOINTS IN THE UPPER 60S. LATEST VISIBLE IMAGERY SHOWS A LINE OF
CUMULUS EXTENDING ALONG A COLD FRONT FROM ERN IA SWWD INTO SWRN IA
AND NWRN MO. THE CAP HAS WEAKENED SUFFICIENTLY TO SUGGEST ADDITIONAL
STORMS WILL DEVELOP FARTHER SWWD ALONG THE FRONT. WSWLY LOW LEVEL
FLOW VEERING TO NWLY AT 35 TO 40 KT AT 6 KM WILL RESULT IN
SUFFICIENT VERTICAL SHEAR FOR SOME UPDRAFTS TO DEVELOP MID LEVEL
ROTATION. THIS ALONG WITH MODERATE INSTABILITY MAY ENHANCE THE
THREAT FOR HAIL WITH THE STRONGER STORMS. ISOLATED WET MICROBURSTS
WILL ALSO BE POSSIBLE WITH THE STRONGER CORES THROUGH EARLY EVENING.
