NWS STORM PREDICTION CENTER NORMAN OK
300 PM CDT TUE JUN 2 2026
THE NWS STORM PREDICTION CENTER HAS ISSUED A
* SEVERE THUNDERSTORM WATCH FOR PORTIONS OF
NORTH DAKOTA
* EFFECTIVE THIS TUESDAY AFTERNOON AND EVENING FROM 300 PM UNTIL
1000 PM CDT.
* PRIMARY THREATS INCLUDE...
SCATTERED LARGE HAIL AND ISOLATED VERY LARGE HAIL EVENTS TO 2
INCHES IN DIAMETER POSSIBLE
SCATTERED DAMAGING WIND GUSTS TO 70 MPH POSSIBLE
A TORNADO OR TWO POSSIBLE
SUMMARY...THUNDERSTORMS ARE EXPECTED TO CONTINUE THROUGH THIS
AFTERNOON AND EVENING ALONG AND AHEAD OF A COLD FRONT MOVING INTO
CENTRAL NORTH DAKOTA. MODERATE TO STRONG BUOYANCY AND MODERATE
VERTICAL SHEAR WILL SUPPORT THE POTENTIAL FOR SUPERCELLS, WITH LARGE
TO ISOLATED VERY LARGE HAIL AS THE PRIMARY HAZARDS. THERE IS A
LOW-PROBABILITY TORNADO RISK, MITIGATED BY THE EXPECTATION THAT
CELLS WILL TREND TOWARDS A MORE CLUSTERED MODE RATHER QUICKLY.
DAMAGING GUSTS ARE ALSO POSSIBLE LATER IN THE CONVECTIVE CYCLE AS
BOWING LINE SEGMENTS BECOME MORE COMMON.
THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 90
STATUTE MILES EAST AND WEST OF A LINE FROM 70 MILES NORTH NORTHWEST
OF DEVILS LAKE ND TO 55 MILES SOUTH OF BISMARCK ND. FOR A COMPLETE
DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE UPDATE
