VALID 220325Z - 220400Z

SEVERE THREAT EXPECTED TO EXIT MUCH OF WW 532 BY 04Z.  THE SERN PART
OF THIS WW FROM CRAWFORD/MARION COUNTIES TO ASHLAND TO KNOW COUNTIES
MAY REQUIRE A LOCAL WFO EXTENTION GIVEN THAT THE THREAT FOR SEVERE

ONGOING THUNDERSTORMS HAVE CONSOLIDATED INTO A COUPLE OF LINES OF
STRONG TO SEVERE STORMS ACROSS NRN OH...WITH ACTIVITY MOVING TO THE
ESE AT 30-40 KT.  THESE LINES OF STORMS ARE TRACKING ESEWD ALONG AN
INSTABILITY GRADIENT AND CONTINUE TO BE MAINTAINED FROM THE
SOUTHWEST PER A 35 KT SWLY LLJ AND A VERY UNSTABLE AIR MASS
EXTENDING FROM SRN IL/IND INTO SWRN-SRN OH.  GREATEST THREAT IS
EXPECTED TO BE FROM DAMAGING WINDS AS WAS EVIDENT AT FDY AROUND 03Z
WITH A RECORDED SEVERE WIND GUST OF 53 KT.

ISOLATED SEVERE STORMS WILL REMAIN POSSIBLE FOR THE NEXT 1-2 HOURS
ACROSS SERN LOWER MI AND FAR NORTH CENTRAL OH IN THE WAKE OF THE WRN
MOST LINE OF STORMS...GIVEN EFFECTIVE BULK SHEAR VALUES AND
INSTABILITY REMAINING SUFFICIENT FOR STORM ORGANIZATION.
