NWS STORM PREDICTION CENTER NORMAN OK
0200 AM CDT FRI APR 24 2026
AREAS AFFECTED...SOUTHERN MISSOURI...NORTHWEST ARKANSAS AND
NORTHEAST OKLAHOMA
CONCERNING...SEVERE THUNDERSTORM WATCH 140...
VALID 240700Z - 240830Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 140
CONTINUES.
SUMMARY...A LINE OF STRONG-ISOLATED SEVERE STORMS WILL PERSIST FOR
THE NEXT COUPLE OF HOURS WHILE SPREADING EASTWARD ACROSS SOUTHERN
MISSOURI AND SOUTHEASTWARD ACROSS NORTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS.
DISCUSSION...CONVECTION HAS EVOLVED INTO AN EXTENSIVE LINE ACROSS
NORTH CENTRAL AND NORTHEAST OK INTO SOUTHWEST MO AND EXTREME
NORTHWEST AR. THE MORE NORTH-SOUTH PART OF THE LINE IN SOUTHWEST MO
IS ORIENTED MORE ORTHOGONAL TO THE DEEP-LAYER SHEAR VECTORS,
SUGGESTING UPRIGHT CONVECTION MAY REMAIN CLOSELY TIED TO THE LEADING
EDGE OF THE COLD POOL. SEVERE POTENTIAL WILL PERSIST IN THE
CORRIDOR WHERE THE NORTH-SOUTH SEGMENT INTERSECTS THE MORE EAST-WEST
OUTFLOW, THOUGH DECREASING BUOYANCY WITH EASTWARD EXTENT CASTS SOME
DOUBT ON THE DURATION AND MAGNITUDE OF THE SEVERE THREAT. FARTHER
WEST, AN EXTENSIVE COLD POOL HAS SAGGED SOUTH OF THE PRIMARY
CONVECTION IN OK, WHERE A 50+ KT LOW-LEVEL JET IS SUPPORTING RENEWED
STORM DEVELOPMENT ATOP THE COLD POOL. OVERALL, THE MAGNITUDE OF THE
WIND/HAIL THREAT SHOULD SLOWLY DECREASE OVER TIME.
