AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
310 AM CDT MON MAY 29 2006

.DISCUSSION...FCST FOCUS IS ON PCPN CHCS THRU WEDNESDAY...ESP TUE
INTO ERLY WED.

MAIN UPPER AND LOW LEVEL JET WILL REMAIN TO OUR WEST TODAY AS
GENERALLY WEAK UPR SW FLOW CONTINUES INTO THE CWA. CI STREAMING
NEWD TOWARDS CWA. MODELS CONTINUE TO INDICATE A WEAK RIPPLE IN THE
FLOW COMING ACRS TODAY. BUFKIT SOUNDINGS FROM BOTH THE NAM AND GFS
HAVE CAPES OF 1-2K WITH VRY LITTLE IN THE WAY OF CIN. THE COMBO OF
INSTAB...WEAK RIPPLE UPSTAIRS AND PSBL SUBTLE LAKE BNDRY LEND
CREDENCE TO KEEPING THE GOING VRY SML POP FOR TODAY.

H8 TEMPS DROP ONLY SLIGHTLY TODAY. NOT EXPECTING THE FULL SUN AS
YESTERDAY SO GOING A SMIDGE COOLER THAN YESTERDAY SEEMS PLAUSIBLE.

MODELS THEN BRING PCPN ASSOC WITH SFC TROF INTO CWA LATER TNGT
INTO TUE. H8 CONVERGENCE INCREASES ON TUESDAY AND WITH UPPER FLOW
RUNNING PARALLEL TO LOWER LEVEL FEATURES...THE SLOW MOVEMENT OF
FRONT LOOKS REASONABLE. GFS GENERATING LARGE QPF AMOUNTS DURING
THE PERIOD BUT THERE ARE ALSO SOME VORTS THAT LOOK SUSPICIOUS AS
WELL...SMALL BULLSYES OF HIGH AMOUNTS BEAR THIS OUT. THE H8
CONVERGENT ZONE LOOKS TO BE A PLAYER INTO AT LEAST ERLY WED. THE RRQ
OF H2 UPR JET ENHANCES UPR DVRG ESP TUE AFTN INTO TUE NGT. IN FACT
THE SLOWER GFS WOULD KEEP FAVORABLE DVRG ACRS THE CWA THRU MUCH OF
WED. WOULDNT BE SURPRISED TO SEE SOME DECENT RAINFALL TOTALS WHEN
THIS IS ALL SAID AND DONE.
