Area forecast discussion, Aug 28, 2:00 AM CST, 4 hours 50 minutes before
AREA FORECAST DISCUSSION FOR CENTRAL/N-EAST SD AND W-CENTRAL MN NATIONAL WEATHER SERVICE ABERDEEN SD 300 AM CDT WED AUG 28 2002 MAIN FORECAST CHALLENGE WILL BE THE CHANCE FOR PRECIPITATION THROUGHOUT THE SHORT TERM PERIOD. NO MAJOR DIFFERENCES NOTED OVER THIS REGION BETWEEN THE ETA AND AVN...SO WILL FOLLOW A BLEND. THE GENERAL PATTERN ACROSS THE COUNTRY WILL CHANGE VERY LITTLE DURING THIS FORECAST PERIOD...WITH A LARGE UPPER TROUGH OVER THE WESTERN PART OF THE COUNTRY AND A HIGH EXTENDING FROM THE SOUTHERN PLAINS TOWARD THE GREAT LAKES. AT THE SURFACE...A STATIONARY FRONT EXTENDS FROM WESTERN SOUTH DAKOTA INTO NORTHERN MINNESOTA...AND WILL REMAIN THERE INTO THURSDAY NIGHT. SOUTHERLY WINDS AHEAD OF THIS FRONT WILL KEEP PLENTY OF MOISTURE IN THE CWA. THIS WILL ALSO RESULT IN DECENT INSTABILITIES...WITH LIS OVER -2 EACH DAY AND CAPES NEAR 2000 J/KG. A WEAK SHORTWAVE WILL SLIDE ACROSS THE AREA TODAY INTO TONIGHT...WHICH SHOULD SUPPLY ENOUGH ENERGY FOR SCATTERED THUNDERSTORMS THIS AFTERNOON INTO THIS EVENING. DO NOT EXPECT A WIDESPREAD OUTBREAK...AS MID TO UPPER LEVEL WINDS REMAIN FAIRLY WEAK. WILL KEEP A CHANCE GOING ON THURSDAY WITH THE FRONT SO CLOSE...WITH A SLIGHTLY BETTER CHANCE DURING THE DAY FRIDAY AS A MORE SIGNIFICANT WAVE TRAVERSES THE STATE AND A SURFACE TROUGH INTENSIFIES OVER THE WESTERN HIGH PLAINS. BY FRIDAY NIGHT...THE WAVE WILL BE NORTHEAST OF THE CWA AND A SURFACE LOW WILL BE INTENSIFYING OVER LAKE WINNIPEG...SO EXPECT PRECIP TO STAY NORTH OF THE CWA. MODEL TIME SECTIONS INDICATE ENOUGH MOISTURE AROUND THROUGH A FAIRLY DEEP LAYER OF THE ATMOSPHERE BEGINNING LATER TODAY TO KEEP THE MENTION OF MOSTLY CLOUDY SKIES. NO BIG CHALLENGE WITH TEMPERATURES...THOUGH CLOUD COVER MAY HINDER THEM SOME EACH DAY. STILL STUCK FAIRLY CLOSE TO THE SLIGHTLY WARMER MET GUIDANCE. .ABR...NONE. PARKIN
