AREAS AFFECTED...SOUTHWEST MINNESOTA...SOUTHEAST SOUTH DAKOTA...FAR
NORTHWEST IOWA...AND NORTHEAST NEBRASKA
CONCERNING...SEVERE THUNDERSTORM WATCH 243...
VALID 250148Z - 250315Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 243
CONTINUES.
SUMMARY...LARGE-HAIL POTENTIAL IS EXPECTED TO BECOME MORE ISOLATED
THROUGH 04Z.
DISCUSSION...RECENT RADAR AND SATELLITE TRENDS INDICATE WARMING
CLOUD TOPS AND LOWERING REFLECTIVITY CORES, WHICH COINCIDES WITH THE
GRADUAL COOLING AND STABILIZATION OF THE BOUNDARY LAYER. HOWEVER,
PLAN-VIEW VWP DATA AND SHORT-TERM MODEL FORECASTS INDICATE THE
STRENGTHENING OF A NOCTURNAL LOW-LEVEL JET FROM SOUTH-CENTRAL NE
INTO SOUTHEAST SD. ENHANCED CONVERGENCE AND MOIST FLUX WITHIN THE
TERMINUS OF THAT FEATURE MAY SUPPORT THE CONTINUATION OF ISOLATED,
STRONG TO SEVERE STORMS IN FAR SOUTHEAST SD AND NORTHWEST IA FOR THE
NEXT HOUR OR TWO. ELSEWHERE, EXPECT A GRADUAL DECREASE IN STORM
COVERAGE AND INTENSITY THROUGH 04Z AS CONVECTIVE INHIBITION
CONTINUES TO INCREASE.
