What happened
The episode as NWS MKX wrote it up.
Widely scattered airmass thunderstorms popped up during the afternoon hours across south-central and southeast Wisconsin. One relatively long-lived storm pulsed to severe limits a couple times as it moved from Columbia County to extreme southeastern Jefferson County. Large hail was generated by this severe storm, however, no damage was noted. Synoptically, an upper-level trough moved southeast through Wisconsin during the afternoon, with a pool of colder air aloft. Maximum air temperatures at the surface rose into the upper 60s to upper 70s range across southern Wisconsin.

Area forecast discussion, Sep 30, 1:58 PM CST, 1 hour 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 258 PM CDT SAT SEP 30 2006 .DISCUSSION...FORECAST FOCUS ON FOG AND PATCHY FROST FORMATION TONIGHT AND WARM AIR ADVECTION PRECIPITATION SUNDAY NIGHT INTO EARLY NEXT WEEK. IN THE SHORT TERM...WITH QUICK EXIT OF 500 MILLIBAR SHORT WAVE THIS EVENING...RUC/GFS/NAM/NGM PROGS QUICKLY CLEAR SKIES AND CALM OUT WINDS AS SURFACE HIGH SETTLES OVER AREA. AFTER MIDNIGHT...GFS GUIDANCE VERY QUICKLY LOWERS BOTH TEMPERATURE AND DEW POINTS...MAINLY OVER WESTERN CWA. FEEL THAT THIS VERY RAPID FALL OF TEMPERATURES/DEW POINTS...INDICATING EXCELLENT RADIATIONAL COOLING...WILL ALSO LEAD TO FOG FORMATION...ESPECIALLY IN RIVER VALLEYS. SOME TEMPERATURES COULD COOL ENOUGH TO PRODUCE PATCHY FROST IN LOW LYING AREAS WITH HELP OF LONGER NIGHTTIME HOURS. IN THE LONG TERM...HIGH PRESSURE SLIPS RAPIDLY TO THE EAST AND ALLOWS DECENT WARM AIR ADVECTION PATTERN TO SET UP OVER CWA BY SUNDAY AFTERNOON. GFS IS THE ONLY PROG CONSISTENT IN THE LAST 2 DAYS WITH DEVELOPMENT OF CONVECTION SUNDAY NIGHT. MAJOR DIFFERENCES BETWEEN GFS AND NAM/NGM SHOW UP IN MOISTURE FIELDS AND AS A RESULT THERE IS A MAJOR DIFFERENCE IN INSTABILITY FIELDS AS WELL...WITH GFS BEING MORE MOIST AND UNSTABLE. DECIDING FACTOR TO PUT LOW CHANCE CONVECTION IN FORECAST WAS COMBINATION OF LOW LEVEL AND MID LEVEL LIFT BY GFS/NAM PROGS AND PRESENCE OF DEVELOPING 850 MILLIBAR THERMAL RIDGE ACROSS CWA. IN THE LONG LONG TERM...SYNOPTIC SETUP REMAINS FAVORABLE FOR A WET AND UNSETTLED PERIOD OF WEATHER THROUGH MID WEEK AS SLOWER GFS SOLUTION FAVORED WITH REGARDS TO APPROACHING LOW PRESSURE FROM PLAINS AND FRONTAL BOUNDARY AROUND REGION. THUS HAVE ALSO LEANED TOWARD WARMER TEMPERATURE GUIDANCE AS WELL. && .MKX WATCHES/WARNINGS/ADVISORIES... NONE. && ZAJDEL
