AND FOR TRAVERSE/BIG STONE COUNTIES OF MN
NATIONAL WEATHER SERVICE ABERDEEN SD
950 AM CDT SUN JUN 1 1997

WARM ADVECTION WILL OCCUR TODAY ESPECIALLY IN CENTRAL SOUTH DAKOTA.
THIS MAY RAISE TEMPERATURES A TAD HIGHER THAN FORECAST. ALTHOUGH
TEMPERATURES HAVE GONE UP SLOWLY THIS MORNING...AS MORE SUNSHINE GETS
THROUGH A THIN OVERCAST AT PIR TEMPERATURES SHOULD REBOUND NICELY.
TEMPERATURES MAY REACH THE UPPER 80S TODAY THERE SO TWEAKED THE MINOR
ADJUSTMENT WITH A NOWCAST. ALSO COVERED THE NORTHEAST AS WELL BECAUSE
TEMPERATURES ARE GOING UP QUICKLY THIS MORNING. OTHERWISE...THE FORECAST
LOOKS GOOD WITH PARTLY CLOUDY HOLDING TRUE OVER THE CWA BECAUSE HIGH
OVERCAST CEILING WILL BE MOSTLY THIN. ALSO...CHANCE OF STORMS FOR THIS
AFTERNOON CONTINUES FOR CENTRAL AND NORTHCENTRAL. THUNDERSTORMS SHOULD
HOLD OFF IN THE NORTHEAST UNTIL THIS EVENING...HOWEVER WILL WATCH
CAREFULLY BECAUSE CONVECTION COULD DEVELOP NEAR THE MISSOURI RIVER THIS
AFTERNOON AND HEAD EAST.
