NWS Milwaukee, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at May 24, 1:30 PM CDT, 5 hours 43 minutes earlier.
Area forecast discussion, May 24, 1:30 PM CDT, 5 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 130 PM CDT WED MAY 24 2006 .DISCUSSION...FORECAST FOCUS ON POTENTIAL FOR SEVERE THUNDERSTORMS LATE THIS AFTERNOON AND EARLY EVENING. CONVECTION IN THE EAST EARLY THIS AFTERNOON IS ELEVATED AND ASSOCIATED WITH THE EARLIER CONVECTION THAT WAS OVR ERN IA THIS MORNING. H5 S/W WITH THIS AS WELL AS SOME H8 TEMP ADVECTION AND LLV MOISTURE FLUX CONVERGENCE. IMPRESSIVE SINCE LLVS VRY DRY AND RATHER COOL IN THE EAST...BUT THEY ARE STRUGGLING TO REACH ANY SIGGY DEPTH. ONCE CELL WENT OVR THE RDA AND PRODUCED BRIEF VERY TROPICAL- LIKE RAINFALL. LATEST OBSERVATIONS CONFIRM NAM/S INABILITY TO RESOLVE THE SFC DWPNTS. NAM SHOWING DWPNTS EARLY THIS AFTN REACHING INTO THE LOWER 70S ACRS THE WRN CWA AND THIS IS ABOUT 8 DEG TOO HIGH. THIS HAS A HUGE IMPACT ON MODEL DERIVED INSTABILITY AND QPF...ERGO TOO MUCH OF BOTH. PLUME OF HIGHEST DWPNTS...MID/UPR 60S...HAS ITS AXIS RUNNING FM SCNTRL/SE IA NORTH ACRS SE TIP OF MN INTO NW WI. FOCUS IS ON SFC TROF ARCHING FM LOW PRES CENTER OVR WCNTRL MN. THE TROF STRETCHES FM LOW INTO SE MN BACK INTO SCNTRL IA. TEMPS RIGHT AHEAD OF IT ARE WARMING...BUT MAYBE NOT AS MUCH AS EXPECTED DUE TO DVLPMNT OF SC IN WARM SECTOR. NAM WITH ADJUSTED SFC DWPNTS SHOWS MLCAPES OVR MSN BY 00Z GETTING TO NEAR 1500J/KG...BUT THERE IS A CAP WITH CIN VALUES OF -100J/KG. WEAKER CAP TO THE WEST SHOULDN/T INHIBIT CONVECTION MUCH AND ONCE GOING...THE CAP FOR SOME DISTANCE EAST WILL EASILY BE OVERCOME. IT MAY JUST INDICATE THE STRUGGLE THE CONVECTION SHOULD HAVE AS IT REACHES DRIER AND SLIGHTER COOLER CONDITIONS IN THE FAR EAST. BEST BULK SHEAR VALUES OVR SCNTRL WI AT 00Z REACHING 35KTS...BETTER THAN PREVIOUS RUN. BUT...ONE BIG PROBLEM MAY BE THE FACT THAT THE WINDS ARE VEERING TO SW ALONG THE FNT WITH THE BEST SHEAR AND HELICITY REMAINING WELL OUT AHEAD OF IT. WB ZERO HEIGHTS 9-10KFT SUPPORTING POTENTIAL FOR LARGE HAIL. SOUNDING TOOLKIT SHOWS THETA-E DIFFERENTIAL OF OVR 27K BETWEEN THE MID LEVELS AND THE SFC SUPPORTING STRONG POTENTIAL FOR DOWNBURST WINDS. SPC EARLIER THIS MORNING UPGRADED MOST OF SCNTRL TO MDT ACRS THE WRN CWA WITH SLIGHT RISK OVR ALL BUT THE FAR EAST. STILL EXPECT SOME CONVECTION TO FIRE THIS AFTERNOON...BUT IT SHOULD DIMINISH AS IT REACHES EASTERN WISCONSIN AND MEETS WITH THE DIRURNAL COOLING OF THE EVENING. NEARLY STACKED SYSTEM ROLLS OVERHEAD FOR THURSDAY WITH LIKELY SHOWERS AND ISOLATED THUNDERSTORMS. CORE OF THIS LOW NOT THAT COOL SO TEMPS STILL EXPECTED TO REACH NEAR 70. DRIER ON FRIDAY WITH THE UPPER RIDGE BUILDING FOR THE WEEKEND. THE DOOR OPENS FOR THE HEAT BY SUNDAY AS THE MAIN WAA AND UPR JET SHIFT NORTH SATURDAY NIGHT. BUMPED TEMPS INTO THE UPPER 80S FOR SUNDAY AND MONDAY AND WOULDN/T BE SURPRISED TO SEE SOME 90S SHOWING UP LATE IN THE MEMORIAL DAY WEEKEND. UNSEASONABLY WARM WEATHER TO CONTINUE INTO THE MIDDLE OF NEXT WEEK. && .MKX WATCHES/WARNINGS/ADVISORIES... NONE. && DAVIS
