DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1251 AM CDT THU APR 09 2026
VALID 101200Z - 111200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF
THE CENTRAL AND SOUTHERN PLAINS INTO THE OZARKS...
..SUMMARY
THUNDERSTORMS WITH ISOLATED LARGE HAIL AND SEVERE GUSTS WILL BE
POSSIBLE ON FRIDAY OVER PARTS OF THE SOUTHERN AND CENTRAL PLAINS
EASTWARD INTO THE OZARKS.
..SOUTHERN AND CENTRAL PLAINS/OZARKS
AN UPPER-LEVEL RIDGE WILL MOVE THROUGH THE ROCKIES ON FRIDAY, AS
MID-LEVEL FLOW REMAINS WESTERLY ACROSS MUCH OF THE GREAT PLAINS AND
MISSISSIPPI VALLEY. AT THE SURFACE, A COLD FRONT WILL ADVANCE SLOWLY
SOUTHWARD TO NEAR THE KANSAS AND OKLAHOMA STATE-LINE BY MIDDAY.
WARMING SURFACE TEMPERATURES AND INCREASING LOW-LEVEL CONVERGENCE
NEAR THE FRONT WILL RESULT IN ISOLATED TO SCATTERED THUNDERSTORM
DEVELOPMENT IN THE AFTERNOON AND EVENING. SURFACE DEWPOINTS IN THE
LOWER 60S F WILL CONTRIBUTE TO A POCKET OF INSTABILITY NEAR THE
FRONT IN THE AFTERNOON, WITH MLCAPE FORECAST TO PEAK AROUND 1500
J/KG. IN ADDITION, DEEP-LAYER SHEAR IS FORECAST TO BE AROUND 30
KNOTS NEAR THE FRONT WITH LOW TO MID-LEVEL LAPSE RATES IN THE 7 TO 8
C/KM RANGE. THIS ENVIRONMENT SHOULD BE SUFFICIENT FOR AN ISOLATED
SEVERE THREAT. SEVERE WIND GUSTS AND HAIL WILL BE THE PRIMARY
THREATS.
