   SOUTH DAKOTA...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR WESTERN SOUTH DAKOTA AND
NORTHEASTERN WYOMING.

.DAY ONE...TODAY AND TONIGHT

A STRONG COLD FRONT AND UPPER LEVEL DISTURBANCE WILL COMBINE TO
PRODUCE SCATTERED THUNDERSTORMS OVER THE AREA THIS AFTERNOON AND

SEVERE OVER WESTERN AND SOUTH CENTRAL SOUTH DAKOTA...PARTICULARLY
ALONG AND EAST OF A LINE FROM LEMMON TO RAPID CITY TO HOT SPRINGS.

IS ALSO THE CHANCE THAT A TORNADO MAY DEVELOP FROM SOME OF THESE
STORMS...PARTICULARLY OVER SOUTH CENTRAL SOUTH DAKOTA ALONG AND EAST
OF A LINE FROM KADOKA TO MARTIN.

IN ADDITION...ABUNDANT MOISTURE WILL COMBINE WITH POTENTIALLY SLOW
MOVING THUNDERSTORMS TO PRODUCE LOCALLY HEAVY RAINFALL. THIS WILL
RESULT IN THE POTENTIAL FOR FLASH FLOODING THIS AFTERNOON AND
EVENING ACROSS WESTERN AND SOUTH CENTRAL SOUTH DAKOTA.
