THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 502
CONTINUES.

SUMMARY...ISOLATED DAMAGING WIND RISK MAY YET DEVELOP WITH A QLCS
MOVING E ACROSS PARTS OF IL. OVERALL RISK SHOULD WANE AFTER SUNSET
WITH AN ADDITIONAL WW ISSUANCE UNLIKELY BEYOND 01Z EXPIRATION.

DISCUSSION...RISK OF ISOLATED DAMAGING WINDS FOR A COUPLE MORE HOURS
SHOULD PRIMARILY EXIST WITH THE BAND OF STORMS LOCATED NEAR THE
SURFACE COLD FRONT THAT EXTENDED FROM NEAR DNV TO STL AS OF 23Z. THE
NRN PORTION OF THIS LINE IS AMIDST STRONGER MID-LEVEL FLOW PER ILX
VWP DATA WITH 50 KT W/SWLYS TO 4 KM AGL. STILL...WITH FLOW NEARLY
PARALLEL TO THE ORIENTATION OF THE LINE...CONVECTION MAY STRUGGLE TO
INTENSIFY BEYOND STRONG WIND GUSTS PRODUCING ISOLATED DAMAGING
WINDS. FARTHER SOUTH...CLUSTERS HAVE STRUGGLED TO ORGANIZED AMIDST
WEAKER/VEERED FLOW. OTHERWISE...SEVERE THREAT HAS ENDED BEHIND THE
LINE FROM VERMILLION COUNTY IL TO FRANKLIN COUNTY MO.
