AREAS AFFECTED...NORTHEAST OH AND WESTERN PA  
 
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE  
 
VALID 052151Z - 052345Z  
 
PROBABILITY OF WATCH ISSUANCE...60 PERCENT  
 
SUMMARY...AN ISOLATED DAMAGING GUST RISK WILL LIKELY DEVELOP AS A  
SQUALL LINE MOVES INTO NORTHEAST OH FROM THE WEST.  
 
DISCUSSION...RADAR MOSAIC SHOWS A SQUALL LINE OVER NORTH-CENTRAL OH  
MOVING EAST AROUND 55 KT. ASOS MEASURED GUSTS FROM THIS  
THUNDERSTORM BAND HAVE RECORDED GUSTS RANGING FROM 36 KT AT  
WAPAKONETA, 39 KT AT FINDLAY, AND 43 KT AT LIMA. WIDESPREAD WINDS  
OF 45-55 MPH HAVE LIKELY OCCURRED DURING THE PAST HOUR BASED ON  
THESE OBSERVATIONS AND IT SEEMS PROBABLE THIS WILL CONTINUE TO  
LOCALIZED HIGHER GUSTS OF 55-65 MPH. THE AIRMASS AHEAD OF THE LINE  
IS MOIST WITH DEWPOINTS IN THE LOWER 60S DEGREES F AND MARGINALLY  
UNSTABLE. GIVEN THE DEVELOPMENT OF AN ATTENDANT MCV AND  
ORGANIZED/MATURE REAR INFLOW JET TO THE SQUALL LINE, IT WILL MOVE  
INTO NORTHEAST OH AND EVENTUALLY WESTERN PORTIONS OF PA IN A FEW  
HOURS. A RISK FOR ISOLATED DAMAGING WINDS WILL LIKELY ACCOMPANY THE  
SQUALL LINE.
