Severe Thunderstorm Warning 10, NWS Milwaukee, WI

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
230 PM CDT FRI MAY 30 2003

FORECAST FOCUS IS TWOFOLD WITH SYS COMING DOWN IN NW FLOW TNGT.
FIRST IS EXTENT OF TSTMS AND SECOND IS WIND ON BACKSIDE OF LOW LTR
TNGT/ERLY SAT.

STG SFC LOW IS NOW INTO NW WI WITH CDFNT TRAILING SWD TO MO. TSTMS
ARE TRYING TO DVLP ALG AND AHD OF FNT. LOTS OF FAVORABLE FACTORS
OVR CWA THIS EVE TO SUSTAIN OR INCR STORM INTENSITY. CDFNT PRBLY NOT
COMING THRU ERN CWA TIL AFT 00Z. STG VORT CNTR...GENERATING IMPRV
COMMA CLD ON STLT LOOPS...TRACKS DOWN THRU WRN WI INTO NRN IL.
NARROW BAND OF MSTR AND INSTAB JUST AHD OF FNT...DWPTS INTO THE
60S AND LI/S ARND -2 OR -3. H7 OMEGA INCREASES MARKEDLY IN THE EAST
AS WELL. WL HANG ON TO TSTM THREAT THIS EVE TIL FNT PASSES AND
MENTION PSBLTY OF SVR IN ACCORDANCE WITH SWODY1 AND RECENT SWOMCD.

ATTN THEN TURNS TO INCRG WNDS IN TIGHTENING GRAD BHND DEPARTING SFC
LOW. TROFINESS ARND THE LOW ITSELF DOES NOT REALLY CLR THE AREA UNTIL
AFT MIDNITE. SO WL WAIT TIL THEN TO APPRECIABLY CRANK UP THE SPEEDS.
DUE TO THE LATENESS OF THE HR WL HOLD OFF ON HEADLINES FOR NOW.
ANOTHER REASON FOR THAT IS THAT WE MAY GET EVEN HIGHER WNDS WITH SOME
OF THE TSTMS COMING THRU THIS EVE. STG WNDS SHUD THEN CONTINUE WELL
INTO SAT ESPCLY IN ERN CWA AS DEEPER MIXING ALLOWS FOR BETTER
MOMENTUM TRANSFER OF WNDS ALOFT.

QUIETER WX THEN RTNS WITH COOLISH TEMPS EXPECTED SAT NGT DUE
TO CLR SKIES AND DCRG WINDS UNDER SFC HI PRES.

.MKX...NONE.
