UPDATE
ISSUED AT 1057 AM CDT SUN MAR 30 2025
COLD FRONT IS PROGRESSING ACROSS THE REGION THIS MORNING, WITH A
PRETTY CLEAR INDICATION ON VISIBLE SATELLITE BETWEEN FAYETTEVILLE
AND ROGERS/BENTONVILLE STRETCHING SOUTHWEST TO JUST SOUTH OF
MCALESTER. ENVIRONMENT AHEAD OF THE FRONT IS ALREADY PRETTY
UNSTABLE, WITH LOW TO MID 60S DEWPOINTS COMMON. WITH SOME DAYTIME
HEATING, EXPECT MODERATE TO STRONG INSTABILITY THIS AFTERNOON.
DEEP-LAYER SHEAR IS MORE THAN SUFFICIENT TO SUPPORT SUPERCELLS,
ESPECIALLY GIVEN THAT CELLS ARE MORE LIKELY TO BE DISCRETE TODAY
COMPARED TO LAST NIGHT. LOW LEVEL SPEED SHEAR IS STRONG, BUT
DIRECTIONAL SHEAR IS LACKING. IT WILL TAKE A HARD RIGHT TURN BY A
SUPERCELL /FARTHER OFF THE HODOGRAPH/ TO REALIZE TORNADO
POTENTIAL. THE LATEST HRRR RUNS DEVELOP STORMS NEAR THE FRONT BY
EARLY AFTERNOON FROM SE OK UP INTO NW AR WITH STORMS
STRENGTHENING/MATURING TO THE EAST OF THE FORECAST AREA. ANY STORM
THAT DEVELOPS AND MATURES INTO A SUPERCELL WOULD BE CAPABLE OF
PRODUCING VERY LARGE HAIL /2 INCHES IN DIAMETER OR LARGER/ AND
LOCALLY DAMAGING WIND. AS MENTIONED BEFORE, TORNADO POTENTIAL IS
MORE CONDITIONAL AND DEPENDENT ON STORM MOTION. THE SEVERE THREAT
ENDS BY THIS EVENING WITH THE FRONT CLEARING THE FORECAST AREA.
