Area forecast discussion, Jul 13, 3:27 PM CDT, 1 hour 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 327 PM CDT TUE JUL 13 2004 .DISCUSSION...FORECAST FOCUS ON POTENTIAL FOR SEVERE STORMS LATE THIS AFTERNOON AND EVENING. HAVE BEEN WATCHING SEVERE WEATHER INDICES ALL DAY AND PARAMETERS HAVE PEGGED FAIRLY HIGH FROM MID MORNING ON BUT LACK OF FORCING HAS PRODUCED LITTLE CONECTION. HOWEVER IT NOW APPEARS THAT THE FORCING FROM UPPER LOW TO OUR NORTH WITH SPIRAL BAND WITH VORT COMING THROUGH CWA WILL BE OUR BEST BET FOR SEVERE. WITH SINKING MOVEMENT TO THE SOUTHEAST THE EASTERN PORTION OF CWA IS THE MOST FAVORABLE AREA FOR SEVERE WEATHER. WATCH WILL BE CANCELED EARLIER THAN 04Z ONCE OUR WEATHER MOVES OUT OF CWA THIS EVE. AS DRIER AND MORE STABLE AIR MOVES IN FROM THE WEST TONIGHT WILL END CHANCE OF PRECIPITATION IN FORECAST WITH NORTHWEST FLOW PROVIDING MORE PLEASANT WEATHER FOR NEXT 2 DAYS. && .MKX...WATCHES/WARNINGS/ADVISORIES...NONE
