Area forecast discussion, Sep 2, 3:12 PM CDT, 8 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DULUTH MN 312 PM CDT SAT SEP 2 2000 MAIN FCST PROBLEMS ARE ANY SVR/HEAVY RAIN CHANCES TNGT...AND CLOUD TRENDS AND THEIR EFFECTS ON TEMPS NEXT COUPLE OF DAYS. FOLLOWED ETA FOR THE MOST PART. NGM MUCH FARTHER SOUTH WITH LOW LVL JET AND MAX 850MB INSTABILITY BY 06Z AS COMPARED TO ALL OTHER MODELS. AVN TAKES MAX PRECIP TOO FAR NORTH FROM WARM FRONT AND AWAY FROM BEST MOISTURE/INSTABILITY. ETA SEEMS TO BE DOING BEST JOB WITH MAIN FOCUS JUST NORTH OF WARM FRONT...BUT ALSO ACKNOWLEDGES UPPER LVL LIFT ACROSS NORTHERN TIER FROM RIGHT REAR QUAD. SHOWERS AND THUNDERSTORMS SPREADING INTO NORTHWEST CORNER OF CWA AS WEAKER SHORTWAVE RIDES UP RIDGE AND WITH INCREASING UPPER LVL DIVERGENCE. THIS GRADUALLY MOVES EAST THIS EVENING WITH UPPER LVL SUPPORT. LOW LVL JET CRANKS UP THIS EVENING...AS 850MB LI'S DROP AS LOW AS -5 IN SOUTHERN TIER OF CWA. THIS SHOULD INCREASE THUNDERSTORM COVERAGE ACROSS SOUTHERN CWA DURING THE EVENING AS NEXT SHORTWAVE MOVES MORE EASTERLY TOWARD THIS AREA. KEPT POPS HIGH ACROSS SOUTHERN SECTIONS...BUT LIMITED HEAVY RAIN WORDING FROM HINCKLEY TO PRENTICE...CLOSER TO BETTER INSTABILITY AND ON NOSE OF LOW LVL JET. A FEW ELEVATED SVR STORMS ARE POSSIBLE IN SOUTHERN TIER COUNTIES UNTIL ABOUT MIDNIGHT...BUT BETTER CHANCE JUST TO THE SOUTH. OTHERWISE NVA MOVES IN QUICKLY OVERNIGHT...BRINGING AN END TO MOST OF THE NE MN PRECIP BY MIDNIGHT...AND EVENTUALLY NW WI. WITH STRONG MOIST NORTHEAST FLOW...KEPT DENSE FOG AND DRIZZLE IN OVERNIGHT NEAR THE LAKE...AS WELL AS THROUGH SUNDAY MORNING. CLOUDS TRICKY ON SUNDAY AND MONDAY WITH BAROCLINIC ZONE OVER AREA...AS WELL AS CHC FOR MORE PRECIP. FOR NOW KEPT SUNDAY PESSIMISTIC WITH SOME IMPROVEMENT IN AFTERNOON WHEN HOPEFULLY THE SUN CAN BURN THROUGH SOME OF THE LOWER CLOUD DECKS. DID NOT CHANGE MUCH FOR LABOR DAY DUE TO LOW CONFIDENCE OF THE MODELS. AS FOR TEMPS...KEPT ON THE COOLzER SIDE OF GUIDANCE TEMPS DUE TO CLOUDS. .DLH...NONE. TAP
