AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
230 PM CDT SUN JUN 26 2005

.DISCUSSION...FORECAST FOCUS IS ON HEAT AND HUMIDITY AND THUNDERSTORM
POTENTIAL NEAR AND SHORT TERM...WITH TIMING OF COOLER AND DRIER
CONDITIONS IN LONG TERM.

.NEAR TERM (TONIGHT)...
EXPECT EVENING SHOWERS AND ISOLATED THUNDERSTORMS ASSOCIATED WITH
WEAK SHORT WAVE AND LEFTOVER OUTFLOW FROM MORNING CONVECTION...BUT
LITTLE OR NO PRECIPITATION OVERNIGHT DUE TO LACK OF FORCING
AVAILABLE.

.SHORT TERM (MONDAY THROUGH WEDNESDAY)...

HEAT AND HUMIDITY FOR MONDAY AND TUESDAY WITH STORMS FOR WEDNESDAY
AND WEDNESDAY NIGHT.

MOISTURE AND INSTABILITY TO REMAIN IN PLACE FOR THE SHORT TERM.
TIMING OF LIFT IS PROBLEMATIC AT BEST. BEST LOW LEVEL CONVERGENCE
IS TIED TO WARM FRONT AND SHORT WAVES THAT ENHANCE THE LOW LEVEL
CONVERGENCE AND REMOVE ANY CAPPING. AT THIS POINT...NO SIMPLE WAY TO
DETERMINE WHEN THESE FACTORS WILL BE PHASING TOGETHER GIVEN THE
SOUTHWEST FLOW REGIME AND OUTFLOW BOUNDARIES THAT PROVIDE FOCUS
FOR CONVECTION TO DEVELOP.

SO WILL GO WITH NOMINAL POPS FOR MONDAY THROUGH TUESDAY. WILL
INCREASE POPS FOR WEDNESDAY AND WEDNESDAY NIGHT AS DYNAMICS
ARE MORE READILY APPARENT WITH COLD FRONT...STRONG SHORT WAVE AND
UPPER/LOW LEVEL JET INTERACTIONS MORE LIKELY.

.LONG TERM (THURSDAY THROUGH SUNDAY)...

COOLER AND DRIER CONDITIONS FOR THURSDAY NIGHT AND FRIDAY. WARM
AND HUMID CONDITIONS RETURN FOR SATURDAY WITH PRECIPITATION CHANCES
INCREASING FOR SUNDAY.

WILL KEEP LOW POPS IN FOR THURSDAY AS SHORT WAVE MOVES THROUGH DURING
THE DAY. THEN DRY THEREAFTER.

RELATIVELY FAST MOVING ZONAL FLOW FOR THIS TIME OF YEAR IS
KEEPING SYSTEMS ON THE MOVE ACROSS THE NORTHERN PLAINS AND
GREAT LAKES FOR THE LONG TERM PERIOD. THE GFS AND ECMWF ARE IN
GENERAL AGREEMENT AND ARE USED FOR THIS DISCUSSION.

TIMING OF COLD FRONT WITH COOLER/DRIER CONDITIONS IS MAIN CHALLENGE
AT THIS POINT. COLD FRONT THROUGH CWA THURSDAY MORNING WITH
END TO PRECIPITATION THURSDAY WITH DRIER AND COOLER CONDITIONS
FOR THURSDAY NIGHT AND FRIDAY. RETURN FLOW BECOMES REESTABLISHED
SATURDAY WITH INCREASE IN HEAT AND HUMIDITY FOR SUNDAY ON THE
BACKSIDE OF SURFACE HIGH. WITH INSTABILITY AND MOISTURE IN
PLACE WITH FAST MOVING SHORT WAVES...LOW PROBABILITIES ARE WISE
FOR SUNDAY ACROSS SOUTH CENTRAL AND SOUTHEAST WISCONSIN.

.MKX WATCHES/WARNINGS/ADVISORIES...NONE.
