AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 402 AM CDT TUE AUG 14 2007 .SHORT TERM...TODAY THROUGH WEDNESDAY...FORECAST CONCERNS CONTINUE TO FOCUS ON PCPN...OR LACK OF PCPN AROUND MUCH OF THE CWA. CONVECTIVE COMPLEX SHIFTING SOUTH THROUGH THE AREA EARLY... AMOUNTS AT AIRPORT SITES NOT IMPRESSIVE TO DATE. TENTH OF INCH SOUTH OF A AUW TO ATW LINE...WITH ONLY TRACE AMOUNT IN GRB. COLD FRONT NOW JUST ENTERING FAR NW WI. EXPECTED TO PASS THROUGH CWA THIS MORNING. WILL LINGER CHANCE FOR PCPN UNTIL FRONT PASSES. ALSO STRONGER GRADIENT AHEAD OF FRONT WILL LEAD TO PERIOD OF SMALL CRAFT CONDITIONS THIS MORNING. HIGH PRESSURE WILL BUILD IN TONIGHT. SIMILAR SITUATION AS LAST NIGHTS DEVELOPING FOR LATER WED INTO WED NIGHT. ADDED SMALL POPS WED AFTN AS S/W SHIFTS EAST OVER RIDGE INTO STATE. AT THIS TIME BULK OF PCPN AGAIN APPEARS TO STAY SOUTH WITH DRIER AIR LINGERING OVER NORTHERN WI. MADE LITTLE CHANGE TO TEMP GRIDS .LONG TERM...WED NGT THRU NXT MON. MAIN FCST CHALLENGES INCLUDE PCPN CHCS ASSOCIATED WITH CDFNTL PASSAGE WED NGT...AMT OF DRY AIR TO SPREAD ACROSS THE RGN THU AND FRI...AND THEN PCPN CHCS ONCE AGAIN EARLY NXT WEEK. CDFNT TO SWEEP ACROSS NE WI WED NGT AND SHOULD BE SE OF THE AREA SHORTLY AFTER MIDNGT. IN ADVANCE OF THE FNT...A MODERATELY UNSTABLE ATM TO BE IN PLACE WITH CAPES AROUND 1500 J/KG...LIS AROUND -3 AND MID-LVL LAPSE RATES UP TO 6.5 C/KM (SRN SECTIONS OF THE FCST AREA). HOWEVER...BEST FORCING IS LOCATED TO OUR SOUTH AND LIFT IS NOT OVERLY IMPRESSIVE OVR NE WI. THEREFORE...HAVE KEPT CHC POPS GOING FOR WED NGT WITH HIGHEST POPS ACROSS CNTRL/E-CNTRL WI. INFLUX OF DRIER AIR AND STG SUBSIDENCE TO BRING COOLER...LESS HUMID AND BREEZY CONDITIONS TO THE RGN ON THU. WE WL HAVE TO KEEP AN EYE ON HOW MUCH DRY AIR ARRIVES FOR FIRE WEATHER PURPOSES ESP WITH THE WNDS GUSTING DURING THE DAY. OTHERWISE...CAA BEHIND THE FNT WL LIMIT THE AMT OF DIURNAL WARMING AND MAY HAVE TO TRIM MAX TEMPS DOWN A COUPLE OF DEGS FROM THE PREV FCST (BUT NOT AS LOW AS THE MEX GUID). HI PRES IS EXPECTED TO BEGIN BUILDING EWD TOWARD THE WRN GREAT LKS RGN THU NGT. 8H TEMPS DOWN AROUND +5C AND MOSTLY CLR SKIES WL LEAD TO A COOL NGT OVR NE WI...HOWEVER READINGS TO BE HELD UP A BIT BY 25 KT BNDRY LYR WNDS. ONLY MADE A FEW TWEAKS TO THU NGT MIN TEMPS. THE HI PRES WL GENERALLY BE OVRHD ON FRI PROVIDING FOR MOSTLY CLR SKIES AND LIGHTER WNDS. AIRMASS STILL LOOKS VERY DRY WITH DEW PTS DROPPING INTO THE 40S OVR MUCH OF THE FCST AREA. DESPITE THE COOL AIR ALOFT...THE AMT OF DRY AIR WL ALLOW TEMPS TO QUICKLY WARM WITH READINGS REACHING THE UPR 60S TO LWR-MID 70S. AS THE HI PRES SLIDES TO OUR EAST FRI NGT...WNDS WL BEGIN TO VEER MORE S-SW AT 8H ACROSS THE UPR MIDWEST. A FNTL BNDRY (MOST LIKELY QUASI-STNRY) IS PROGGED TO BE DRAPED ACROSS PARTS OF IA AND IL WITH WAA LOW-LVL JET INDUCED CONVECTION DEVELOPING. THIS CONVECTION SHOULD FOLLOW THE THICKNESS LINES SEWD AND MAINLY AFFECT AREAS TO OUR SOUTH ON SAT. PREV FCST HAD THIS WELL-HANDLED SO MADE LITTLE CHG TO SATS FCST. THE FCST FOR THE END OF THE UPCOMING WEEKEND IS TRICKY DEPENDING ON THE LOCATION FOR THE FNTL BNDRY. IF CONVECTION FROM SAT PUSHES THE SWD JUST A LITTLE BIT...THEN HI PRES TO OUR NORTH MAY BE ABLE TO BRING ENUF DRY AIR TO KEEP SUNDAY DRY. SINCE IT IS QUITE DIFFICULT TO DETERMINE THE BNDRYS LOCATION AT THIS TIME...PREFER TO KEEP A MINIMAL POP OVR SRN SECTIONS OF THE FCST AREA. THE PBLM FOR SUNDAY CONTS INTO MON AS THE BNDRY REMAINS LOCKED TO OUR SOUTH. IT IS CONCEIVABLE THAT BOTH SUNDAY AND MONDAY MAY BE COMPLETELY DRY BUT PREFER AT THIS TIME TO WAIT ON MAKING ANY CHGS TO DAYS 6 AND 7 TO TRY AND DETERMINE WHERE THAT BNDRY WL RESIDE. && .AVIATION...CONVECTIVE COMPLEX TO SHIFT SOUTH OF TAF SITES EARLY MAINLY VFR CONDITIONS EXPECTED. CHANCE OF MORE SHOWERS OR THUNDERSTORMS CONTINUE UNTIL FRONTAL PASSAGE/MID DAY. THOUGH CHANCES TOO LOW TO PUT IN TAFS AT THIS TIME. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && TE/KALLAS
