AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
308 AM CDT THU JUL 26 2007

.SHORT TERM...TODAY/TONIGHT/FRIDAY. MAIN EVENT DURING THIS PERIOD
WILL BE ASSOCIATED HEAVY PCPN/SVR POTENTIAL WITH CDFNT PASSAGE TONIGHT.

BUT FIRST...AN ISOLD BAND OF SHRA/TSRAS CONTINUES THIS AM ALONG A
SURFACE CONVERGENT REGION EXTENDING FROM FLORENCE TO OSH EARLY
THIS AM. THE INDIVIDUAL CELLS ARE MOVING MAINLY DUE SOUTH HOWEVER
THE LINE IS DRIFTING GRADUALLY EASTWARD. THE GFS MODEL APPEARS TO
BE LATCHING ON THIS TREND THE BEST SO WILL LEAN TWD THAT MODEL
THROUGH 18Z TODAY.  PCPN ALSO BEING AIDED WITH GENERAL HEIGHT
FALLS DUE TO UPPER LOW TO THE EAST AND NRN PLAINS SHORT WAVE WITH
FRONTAL SYSTEM...ALONG WITH A MOIST UNSTABLE AIRMASS AND VERTICAL
WIND SHEAR. SLOW MOVEMENT OF THE INDIVIDUAL CELL AIDING WITH
LOCALLY HEAVY RAINFALL...BUT MOVING ENOUGH AT THIS TIME TO PRODUCE
ANY LOCAL FLOODING PROBLEMS.  GROUND TRUTH REPORT FROM AROUND THE
CLI AREA REPORTED HEAVY RAIN SO WILL ADD HEAVY RAIN WORDING EVEN
THOUGH THE MENTION WILL BE ISOLD TO SCT IN THE GOING FCST. WILL
CONTINUE SCT MENTION INTO THE AFTN HOURS OVER ERN DUE TO LOCATION
OF LAKE BREEZE BOUNDARY AND UPPER HEIGHT FALLS AND CHC TO LOCATIONS
WEST.

EXPECT THE PCPN ALONG AND NEAR THE CDFNT TONIGHT TO BE EXCESSIVE
DUE TO THE HIGH PW/S AND UPPER HEIGHT FALLS FROM THE PHASED
SYSTEMS. WILL UP POP MENTION A TAD ABOVE LIKELY. SPC HAS PUT MUCH
OF THE GRB CWA IN DAY 1 SLIGHT RISK. WITH HIGH WET BULB...MAIN SVR
POTENTIAL WILL BE DAMAGING WINDS AND HEAVY RAIN.  NEAR SEVERE HAIL
POSSIBLE WITH STRONGER STORMS LATER TONIGHT. WILL GO INTO MORE
DETAIL IN THE MORNING HWO.

LATEST MODEL RUNS SUPPORT THE CURRENT CHC WORDING FOR FRIDAY
MORNING AND OVER MAINLY THE SOUTHEAST HALF OF THE CWA. DUE
NOTE THAT MODEL SURFACE DEWPOINTS DO NOT FALL THAT MUCH FOR
FRIDAY SO SOME POTENTIAL OF PCPN TO LINGER LONGER.

AS FRONT DRIVES SOUTH...PCPN WILL EVENTUALLY END LATER FRIDAY AS
HIGH PRESSURE SYSTEM BUILDS IN.

.LONG TERM...FRI NGT THRU NXT WED. MAIN FCST CHALLENGE WL BE TEMPS
THRU THE PERIOD AS RATHER TRANQUIL WEATHER PATN SETS UP OVR NE WI.

HI PRES OVR THE UPR MIDWEST WL BUILD SEWD INTO THE WRN GREAT LKS
RGN FRI NGT BRINGING MOSTLY CLR SKIES AND RELATIVELY LGT WNDS TO
NE WI. MAY NEED TO LWR MIN TEMPS A COUPLE OF DEGS AS DRIER AIRMASS
SENDS DEW PTS DOWN INTO THE 50S (EVEN A FEW UPR 40S PSBL OVR NRN
WI). THIS AREA OF HI PRES TO BE ESSENTIALLY OVRHD ON SAT WHICH
SHOULD PROVIDE FOR A MOSTLY SUNNY DAY WITH SEASONAL TEMPS. AREAS
NEAR LK MI TO BE COOLER AS NE WNDS TO PREVAIL.

LITTLE IF ANY CHG EXPECTED INTO SAT NGT WITH THE HI PRES PARKED
OVR WI. ANTICIPATE ANOTHER MOSTLY CLR NGT WITH TEMPS SIMILAR TO
THOSE WITNESSED FRI NGT. SLIGHTLY WARMER CONDITIONS ARE EXPECTED
FOR SUNDAY AS THE ROCKIES UPR RDG EDGES EWD A BIT TOWARD THE
PLAINS. HI PRES AT THE SFC STILL IN OUR VCNTY...THUS ANOTHER
MOSTLY SUNNY DAY ANTICIPATED.

MDLS HINT AT A WEAK SYSTEM TO SLIDE DOWN THE EDGE OF THE UPR RDG
ACROSS ONTARIO SUNDAY NGT INTO MON. ANY PCPN SHOULD REMAIN TO OUR
NORTH AND EAST...HOWEVER NE WI COULD GET SOME OF THE CLDS FROM
THIS SYSTEM ESP FAR NE SECTIONS OF THE STATE. PARTLY CLDY SKIES AT
WORST WHICH WL NOT IMPACT TEMPS (IF AT ALL). THE UPR RDG CONTS TO
EDGE CLOSER BY MON AND REACHES THE UPR MIDWEST WITH 8H TEMPS
REACHING THE UPR TEENS CELSIUS. THE GFS MAY BE TOO AGGRESSIVE WITH
THE WARM-UP AND HAVE KEPT TEMPS IN LINE WITH PREV FCST.

THE ERN PERIPHERY OF THE UPR RDG TO REACH WRN WI BY TUE BRINGING
VERY WARM TEMPS BACK TO THE RGN. WL HAVE TO WATCH FOR ANY
POTENTIAL SHRTWVS ROTATING AROUND THE RDG WHICH COULD MOV INTO WI
AND SET OFF SOME PCPN. NOTHING EVIDENT AT THIS TIME FOR
TUE...THEREFORE WL CONT WITH THE DRY FCST. BY THE MIDDLE OF NXT
WEEK...MDLS HINT AT A DECENT SHRTWV TROF TO BE TRAVERSING ACROSS
THE CANADIAN PRARIE. WHILE THE CORE OF THIS SYSTEM TO REMAIN WELL
TO OUR NORTH (VCNTY WRN ONTARIO BY 00Z THU)...IT WL SERVE TO
WEAKEN THE UPR RDG A BIT OVR THE UPR MIDWEST/WRN GREAT LKS. HAVE
LEFT FCST DRY...BUT THE BRUNT OF THE TRULY HOT WEATHER APRS TO
REMAIN TO OUR WEST.
&&

.AVIATION...SCT TSTMS WILL CONTINUE OVER EASTERN WI NEAR AND ALONG
PERSISTENT LAKE BREEZE BOUNDARY. TSRA/S WILL BE ON THE INCREASE
THIS AFTERNOON OVER THE REST OF THE STATE AS A CDFNT APPROACHES
NORTHWEST WISCONSIN. THE CDFNT IS EXPECTED TO REACH SE WISCONSIN
