AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
233 PM CDT TUE JUL 5 2011

.SYNOPSIS...TYPICAL SUMMER WX EXPECTED FOR THE NEXT WEEK...WITH
TEMPS AOA NORMAL AND A FEW ROUNDS OF THUNDERSTORMS.

SEASONABLY STG BAND OF WESTERLIES WL PERSIST ACRS THE NRN TIER OF
STATES AND SRN CANADA...N OF SUBTROPICAL RIDGE STRETCHED OUT ACRS
THE SRN CONUS. MEAN TROF POSNS WL BE NR THE WEST COAST AND OVER
THE NERN CONUS. THE ERN TROF SHOULD AMPLIFY A BIT THE NEXT COUPLE
DAYS AS SHRTWV NOW CROSSING THE RGN REACHES THE ERN CONUS...THEN
WEAKEN THIS WEEKEND.

THERE WL BE A FEW CHCS OF RAIN AS WX SYSTEMS PROGRESS THROUGH THE
WESTERLIES. MAX TEMPS SHOULD REMAIN AOA NORMAL.
&&

.SHORT TERM...TNGT AND WED. MAIN FCST CONCERNS CONT TO BE EXTENT
OF TSTMS AND SVR POTENTIAL INTO THE EVENING HOURS.

THE 19Z MSAS SFC ANALYSIS SHOWED A TROF OF LOW PRESSURE OVER ERN
WI...THE PRIMARY CDFNT OVER NW WI AND HI PRES BUILDING INTO THE
NRN PLAINS. LATEST RADAR MOSAIC INDICATED A CLUSTER OF TSTMS OVER
E-CNTRL WI ASSOCIATED WITH THE SFC TROF (AND A SHRTWV TROF ALOFT)
INTERACTING WITH MODERATE INSTABILITY. SO FAR THESE STORMS HAVE
BEHAVED THEMSELVES...BUT POTENTIAL OF ISOLATED SVR IS STILL THERE.
OTHER TSTMS HAVE DEVELOPED OVER NW WI AHD OF THE CDFNT SO THESE WL
NEED TO BE DEALT WITH THIS EVENING.

THE INITIAL SHWRS/TSTMS ACROSS E-CNTRL WI LATE THIS AFTERNOON/EARLY
EVENING WL EXIT INTO LK MI...HOWEVER THE CDFNT TO STILL MOVE THRU
THE FCST AREA DURING THE LATE EVENING OR EARLY MORNING HOURS. WL
NEED TO CARRY POPS THRU THE ENTIRE AREA THIS EVENING AND TAPER
DOWN TO ISOLATED OVER E-CNTRL WI DURING THE LATE NGT HOURS. MIN
TEMPS TO RANGE FROM THE MID 50S N-CNTRL...TO THE LWR-MID 60S
E-CNTRL.

THE HI PRES IS FCST TO MOVE INTO THE WRN GREAT LKS ON WED AND
BRING MORE SUNSHINE...SLIGHTLY COOLER TEMPS AND LESS HUMIDITY TO
NE WI. THIS HI PRES IS FAIRLY WEAK AND WL CONT TO WATCH FOR ANY
PCPN ACTIVITY ALONG THE LKBRZ BNDRY WED AFTERNOON. LOOK FOR MAX
TEMPS TO BE NEAR SEASONAL NORMS FOR EARLY JULY WHICH IS TYPICALLY
IN THE LWR 80S.

.LONG TERM...WED NGT THROUGH NEXT TUE. GENERALLY QUIET WX EXPECTED
EARLY IN THE PERIOD. AT VARIOUS TIMES...MODELS HINTING AT SOME
PCPN OVER NRN WI AS WK FRONTAL BOUNDARY SAGS INTO THE AREA. COULD
MAKE A CASE FOR POPS ACRS THE N THU AND AGAIN FRI. OPTED TO LEAVE
THU DRY RATHER THAN PUT IN SLGT CHC POPS NOW. LATER SHIFTS CAN ADD
IF IT STILL LOOKS LIKE THERE IS SOME PCPN POTENTIAL. PROBABLY A
BETTER CASE CAN BE MADE FOR PCPN ON FRI...AS WK SLY FLOW ON BACK
SIDE OF RETREATING  HIGH WL HAVE A LITTLE MORE TIME TO BRING
MOISTURE NWD INTO THE AREA. SO ADDED CHC POPS TO THE N/NE FRI.
STAYED PRETTY CLOSE TO PREV FCST FOR TEMPS.

WEEKEND SYSTEM LOOKING TO HAVE A LITTLE MORE RAIN-PRODUCING
POTENTIAL THAN YDA. THE WEST COAST TROF WL BE A LITTLE MORE
AMPLIFIED BY LATE THIS WK...RESULING IN MORE OF A WSWLY UPR FLOW
TOWARD THE AREA. IT NOW APPEARS A ROUND OR TWO OF STORMS
DEVELOPING IN ISENT LIFT ZONE AHEAD OF THE UPR SHRTWV COULD AFFECT
THE AREA...WITH MAIN FRONT LIKELY TO COME THROUGH DURING THE
LATTER PART OF THE WEEKEND. SOME INDICATIONS THE FRONT COULD STALL
CLOSE ENOUGH TO CAUSE CHC OF PCPN TO LINGER ACRS THE S INTO EARLY
NEXT WK...BUT AT THIS POINT TRENDED FCST TOWARD THE MORE AMPLIFIED
LOOK OF THE EMCWF WITH THE ERN TROF. THAT SHOULD DRIVE THE FRONT
FAR ENOUGH S TO KEEP RN CHCS S OF THE AREA...AND BRING A COUPLE
DRY DAYS WITH A LITTLE COOLER TEMPS AND LOWER HUMIDITIES.
&&

.AVIATION...SCT TSTMS MAY OCCUR THROUGHOUT NE WI LATE THIS
AFTERNOON THRU THE EVENING HOURS AS A SFC TROF AND CDFNT PUSH THRU
THE STATE. FOR THE MOST PART...VFR CONDITIONS ARE ANTICIPATED.
HOWEVER...BRIEF MVFR CIGS/VSBYS WL OCCUR IN AND AROUND ANY TSTMS.
&&

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
