AREAS AFFECTED...PARTS OF EASTERN SD INTO WEST-CENTRAL/SOUTHWEST MN
CONCERNING...TORNADO WATCH 271...
VALID 040137Z - 040300Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 271 CONTINUES.
SUMMARY...SOME THREAT FOR HAIL, DAMAGING WIND, AND POSSIBLY A
TORNADO MAY CONTINUE THROUGH THE EVENING.
DISCUSSION...A SMALL STORM CLUSTER WITH A HISTORY OF PRODUCING
SEVERE GUSTS ACROSS FAR NORTHEAST SD IS APPROACHING THE SD/ND/MN
BORDER INTERSECTION AS OF 0130 UTC. LOW-LEVEL MOISTURE AND BUOYANCY
WEAKEN WITH EASTWARD EXTENT, WHICH WILL TEND TO LIMIT THE LONGEVITY
OF THE SEVERE THREAT WITH THIS CLUSTER INTO WEST-CENTRAL MN.
HOWEVER, GIVEN THE CURRENT ORGANIZATION OF THIS CLUSTER, SOME THREAT
FOR DAMAGING WIND AND ISOLATED HAIL COULD SPREAD EAST OF WW 271
BEFORE A DEFINITIVE WEAKENING TREND OCCURS. GIVEN THE EXPECTED
WEAKENING TREND WITH TIME, THE NEED FOR DOWNSTREAM WATCH ISSUANCE IS
UNCERTAIN.
FARTHER SOUTH, RELATIVELY DISORGANIZED CONVECTION IS ONGOING ACROSS
EAST-CENTRAL SD. THE ENVIRONMENT ACROSS THIS AREA REMAINS SOMEWHAT
FAVORABLE, WITH MODERATE BUOYANCY AND SUFFICIENT DEEP-LAYER SHEAR
FOR ORGANIZED CONVECTION. THE ONGOING CONVECTION COULD PRODUCE
SPORADIC HAIL AND ISOLATED STRONG/DAMAGING GUSTS. IT REMAINS
POSSIBLE THAT A SUPERCELL OR TWO COULD EVOLVE ACROSS THIS AREA
THROUGH DUSK, WHICH WOULD RESULT IN AN INCREASING HAIL THREAT, ALONG
WITH SOME TORNADO POTENTIAL.
