Area forecast discussion, May 31, 3:20 PM CDT, 7 hours 18 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 320 PM CDT WED MAY 31 2000 ...FORECAST PROBLEMS HINGE ON PLACEMENT OF WARM FRONT NEXT 24 HOURS. POTENTIAL FOR HEAVY RAINFALL TONIGHT AND THURSDAY MORNING AND THE POSSIBILITY OF SEVERE WEATHER... 18Z SURFACE ANALYSIS SHOWS WARM FRONT EXTENDING FROM SOUTHEAST NEBRASKA...THROUGH CENTRAL IOWA AND ON INTO NORTHERN ILLINOIS. ANOTHER BOUNDARY NOTED ACROSS EXTREME NORTHERN IOWA. CONVECTION REDEVELOPING ALONG AND TO THE NORTH OF THE WARM FRONT. 12Z MODELS IN GOOD AGREEMENT THROUGH 36 HOURS WITH THE AVN THEN BECOMING FASTER WITH REGARDS TO THE MIDWEST WAVE. PREFER THE FASTER AVN SOLUTION FOR THE OUTER PERIODS. BACK BUILDING CONVECTION SHOULD CONTINUE TO THE NORTH OF THE FRONT THROUGH THE EVENING HOURS. FAVORABLE LAPSE RATES AND SHEAR PROFILES SHOULD HELP CONVECTION TO REMAIN ORGANIZED THROUGH THE EVENING WITH THE MAIN THREAT BEING FROM LARGE HAIL. LOW LEVEL JET DEVELOPS TONIGHT ACROSS THE PLAINS AND SHIFTS EASTWARD INTO IOWA/SOUTHERN MINNESOTA BY MORNING. MODELS PROG WARM FRONT TO LIFT SLOWLY NORTHWARD OVERNIGHT. NOSE OF LOW LEVEL JET INTO SOUTHEAST MINNESOTA SHOULD ENHANCE UPWARD MOTION. PRECIPITABLE WATER VALUES QUITE HIGH (APPROACHING 2 INCHES NEAR BOUNDARY) WILL RESULT IN LOCALLY HEAVY RAINS. WITH PREVIOUS HEAVY RAINS OVER NORTHEAST IOWA WILL ISSUE FLASH FLOOD WATCH FOR THIS AREA. SINCE SOUTHEAST MINNESOTA HAS AVOIDED MUCH OF THE HEAVIER RAIN...WILL HOLD OFF ON ANY WATCH AT THIS TIME AND ISSUE FLOOD POTENTIAL OUTLOOK. ON THURSDAY...WARM FRONT CONTINUES TO SHIFT NORTHWARD. SOME UNCERTAINTY AS TO POSITION...THUS WILL CONTINUE WITH RATHER HIGH POPS ACROSS THE AREA. IT LOOKS AS THOUGH MUCH OF THE SOUTHERN ZONES WILL BE IN THE WARM SECTOR. CONVECTIVE PARAMETERS INDICATE ANOTHER ROUND OF SEVERE WEATHER POSSIBLE BY AFTERNOON. AS LOW PULLS NORTHEASTWARD ALONG FRONT SHOULD FINALLY SEE BOUNDARY EXIT THE AREA THURSDAY NIGHT AND FRIDAY WITH DRY WEATHER SETTLING IN FOR THE WEEKEND. COORDINATION WITH KMKX...KMPX...KDMX...KDVN.
