SUMMARY...A WIND DAMAGE THREAT MAY CONTINUE TO MOVE ACROSS PARTS OF
SRN ND AND NRN SD EARLY THIS EVENING. THE THREAT WILL REMAIN
ISOLATED AND WW ISSUANCE IS NOT ANTICIPATED.

DISCUSSION...THE LATEST WATER VAPOR IMAGERY SHOWS A SHORTWAVE TROUGH
NEAR THE MT-ND STATE-LINE. THIS FEATURE WILL MOVE EWD INTO THE WRN
DAKOTAS OVER THE NEXT FEW HOURS PROVIDING LARGE-SCALE ASCENT TO AID
THUNDERSTORM DEVELOPMENT. AT THE SFC...A COLD FRONT EXTENDS SWWD
FROM NEAR GRAND FORKS ND SWWD TO NEAR PIERRE SD. SFC DEWPOINTS ALONG
THE TROUGH RANGE FROM THE LOWER 30S F TO THE UPPER 40S F IN ERN ND.
IN ADDITION TO THE DRY BOUNDARY LAYER...SFC TEMPS ARE IN THE MID TO
UPPER 70S F. TEMP-DEWPOINT SPREADS AROUND 40 F ALONG WITH INVERTED-V
THERMODYNAMIC PROFILES EVIDENT ON FORECAST SOUNDINGS SHOULD HELP
ACCELERATE DOWNDRAFT SPEEDS. AS A RESULT...CONDITIONS APPEAR
FAVORABLE FOR STRONG OUTFLOW GUSTS WITH THE DEVELOPING SHOWERS AND
ISOLATED THUNDERSTORMS. A WIND GUST OF 67 KT OCCURRED AT HETTINGER
AT 2030Z AND A FEW MORE WIND GUSTS ABOVE 60 KT CAN NOT BE RULED OUT
AS SHOWERS AND THUNDERSTORMS INCREASE IN COVERAGE OVER THE NEXT FEW
HOURS.
