SEVERE THUNDERSTORM WATCH NUMBER 507
NWS STORM PREDICTION CENTER NORMAN OK
220 PM CDT FRI JUL 11 2025
THE NWS STORM PREDICTION CENTER HAS ISSUED A
* SEVERE THUNDERSTORM WATCH FOR PORTIONS OF
FAR WEST-CENTRAL ILLINOIS
EXTREME NORTHEAST KANSAS
NORTHERN MISSOURI
* EFFECTIVE THIS FRIDAY AFTERNOON AND EVENING FROM 220 PM UNTIL
1000 PM CDT.
* PRIMARY THREATS INCLUDE...
SCATTERED DAMAGING WIND GUSTS TO 70 MPH LIKELY
SCATTERED LARGE HAIL EVENTS TO 1.5 INCHES IN DIAMETER POSSIBLE
SUMMARY...THUNDERSTORM COVERAGE AND INTENSITY IS FORECAST TO
INCREASE FROM NORTHEAST KS ACROSS NORTHERN MO AND INTO WEST-CENTRAL
IL THIS AFTERNOON. STRONG TO EXTREME BUOYANCY IS IN PLACE ACROSS THE
REGION, SUPPORTING THE POTENTIAL FOR ROBUST UPDRAFTS. VERTICAL SHEAR
IS WEAK, WHICH COULD LIMIT STORM ORGANIZATION, BUT THE INTENSE
UPDRAFTS AND RELATED WATER LOADING COULD RESULT IN NUMEROUS STRONG
DOWNBURSTS. A FEW INSTANCES OF HAIL COULD OCCUR AS WELL, BUT WARM
TEMPERATURES SHOULD PRECLUDE A GREATER HAIL THREAT.
THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 45
STATUTE MILES NORTH AND SOUTH OF A LINE FROM LEAVENWORTH KS TO 35
MILES EAST SOUTHEAST OF QUINCY IL. FOR A COMPLETE DEPICTION OF THE
WATCH SEE THE ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU7).
