AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 330 PM CDT WED MAY 17 2006 .DISCUSSION...FCST FOCUS IS ON SEVERE HAIL PRODUCING THUNDERSTORMS ENDING EARLY THIS EVENING. VERY LOW WET BULB ZERO VALUES AROUND 6 THOUSAND FT. STEEP LAPSE RATES WITH COLD MID LEVEL TEMPERATURES...GENERATING CAPES OF 500-1000 J/KG. THIS ENOUGH FOR HAIL UP TO GOLF BALL. HOWEVER MUCH OF THE HAIL IS AROUND 1/2 INCH. SOME WIND GUST POTENTIAL WITH JET MAX PUSHING ACROSS MAINLY IOWA TO THE SW PORTIONS OF THE FORECAST AREA. GOOD UPPER DIFLUENCE ACROSS ESPECIALLY EASTERN PORTION OF FORECAST AREA. BULK RICHARDSON NUMBERS IN THE LOWER 20S. HOWEVER EHIS ARE RATHER LOW. WATER VAPOR SHOWS STG VORT CENTER MOVING ACROSS THE FORECAST AREA. AS VORT MOVES OFF...AND LOSS OF SURFACE HEATING...EXPECT THUNDERSTORMS TO DIMINISH DURING THE EARLY EVENING. QUESTION FOR THU IS TO WHETHER TO PULL THE SMALL CHANCES OF SHOWERS OUT. BUFKIT FORECAST NAM SOUNDINGS SMALL CAPE AROUND 100 J/KG. STEEP LOW LEVEL LAPSE RATES AND CYCLONIC CIRCULATION AROUND DEEPENING UPPER LOW OVER THE EASTERN GREAT LAKES. GUID POPS ONLY AROUND 10 PERCENT.

SMALL CHANCE OF SHOWERS SATURDAY...BUT LOW LEVEL FLOW WEAK...AND VORTS PRODUCING IT MAY BE CONVECTIVE FEEDBACK. 12Z GFS IS TRENDING TOWARD THE EC MODEL RUNS WITH LESS OF A NORTHWEST FLOW IN THE LATER PERIODS. TRENDED THAT WAY...BUT WILL NOT WARM THINGS UP TOO MUCH AS LOW LEVEL EAST FLOW MAY SET UP. && .MKX WATCHES/WARNINGS/ADVISORIES... NONE. && HENTZ
