AREA FORECAST DISCUSSION FOR CENTRAL/NORTH CENTRAL/NORTHEAST SD 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. .ABR...NONE BROYLES
