CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 082100Z - 082330Z

AREAS NEAR THE SRN PORTION OF LAKE MICHIGAN ARE BEING MONITORED FOR
CONVECTIVE INITIATION. ISOLATED DAMAGING WIND AND HAIL WILL BE THE
MAIN THREATS. AREA WILL CONTINUE TO BE MONITORED FOR A POSSIBLE WW.

THIS EVENING A QUASISTATIONARY BOUNDARY EXTENDS ALONG THE IND-MI
BORDER WWD THROUGH NRN IL. THE ATMOSPHERE S OF THIS BOUNDARY HAS
BECOME MODERATELY UNSTABLE WITH MLCAPE AROUND 1500 J/KG AND WITH
A RELATIVELY WEAK CAP. LATEST VISIBLE IMAGERY SHOWS CUMULUS
CONTINUES TO INCREASE AND CONVERGENCE COULD BE LOCALLY ENHANCED
ALONG PARTS OF THE BOUNDARY BY LAKE BREEZE EFFECTS. DEEP LAYER SHEAR
PROFILES ARE SUFFICIENT FOR ORGANIZED STORMS. ONCE STORMS DEVELOP
THEY WILL SPREAD ESEWD ALONG AND N OF THE BOUNDARY ACROSS SWRN MI
INTO EXTREME NRN IND WITH ISOLATED DAMAGING WIND AND HAIL THE MAIN
THREATS.
