AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 238 PM CDT TUE JUL 9 2013 FORECAST DISCUSSION FOR ROUTINE AFTERNOON FORECAST ISSUANCE .SYNOPSIS... ISSUED AT 227 PM CDT TUE JUL 9 2013 SOME THUNDERSTORMS TONIGHT...LESS HUMID FOR THE REST OF THE WORK WEEK...THEN WARMER BY THE WEEKEND. STG ANTICYCLONE CURRENTLY CENTERED OVER THE DESERT SW/SRN PLAINS WL REMAIN THE DOMINANT WX FEATURE ACRS THE CONUS DURING THE PERIOD. SHRTWVS RIDING ARND THE PERIPHERY OF THE HIGH WL BRIEFLY AMPLIFY/ENERGIZE THE UPR TROF OVER THE ERN CONUS THE NEXT COUPLE DAYS. BUT THAT WON/T LAST LONG...AS THE BULK OF ENERGY IN THE TROF WL QUICKLY SHIFT E...ALLOWING THE WRN ANTIYCLONE TO EXPAND EVEN FARTHER E. LOOKS LIKE IT WL END UP STRETCHED OUT ACRS MOST OF THE CONUS BY LATE IN THE PERIOD. MEANWHILE TO THE N...BROAD VORTEX WL CONSOLIDATE OVER THE CANADIAN ARCHIPELAGO...WITH BROAD AND SEASONABLY STG BAND OF WESTERLIES FLOWING ARND THE VORTEX ACRS SRN CANADA AND THE FAR NRN CONUS. THE HUMID AIR PRESENTLY ACRS THE AREA WL BE REPLACED BY MUCH DRIER AIR OF CANADIAN ORIGIN AS THE UPR FLOW TURNS NW INTO AMPLIFYING ERN CONUS UPR TROF. BUT WITH UPR HEIGHTS BUILDING...THE REINFORCING FLOW OF CANADIAN AIR INTO THE AREA WL QUICKLY BE CUT- OFF...ALLOWING THE AIR ACRS THE AREA TO MODERATE. SO TEMPS SHOULD START TO WARM BACK TO ABV NORMAL LEVELS BY LATE IN THE WEEK AND FOR THE UPCOMING WEEKEND. HUMIDITIES WL INITIALLY REMAIN LOW...BUT ARE LIKELY TO EVENTUALLY CREEP BACK UPWARD AS WELL. THE MOST SIG RAIN EVENT WL BE WITH THE COLD FRONT CROSSING THE AREA NOW...THEN SEVERAL DRY DAYS ARE ANTICIPATED BEFORE THE CHC FOR PCPN RETURNS DURING THE LATTER PART OF THE PERIOD. && .SHORT TERM...TONIGHT AND WEDNESDAY ISSUED AT 227 PM CDT TUE JUL 9 2013 MAIN FCST FOCUS TO BE ON TNGT AS A CDFNT SWEEPS THRU THE REGION. STILL CANNOT COMPLETELY RULE OUT SOME SHWRS/TSTMS TO REDEVELOP AS THE AIR MASS AHEAD OF THE FNT MAY BE ABLE TO DESTABILIZE DESPITE THE PASSAGE OF THE CONVECTIVE COMPLEX. THE 19Z MSAS SFC ANALYSIS SHOWED A WEAK AREA OF LOW PRES SITUATED OVER NW WI. A WRMFNT STRETCHED SE FROM THE LOW TO SE WI. THE CDFNT EXTENDED FROM THE LOW SW THRU NW IA TO CNTRL KS. AN AREA OF HI PRES WAS LOCATED OVER THE NRN HI PLAINS. LATEST RADAR MOSAIC SHOWED THE INITIAL COMPLEX OF STORMS FROM NRN TO SE WI AND SHOULD BE CLEAR OF NE WI BY LATE AFTERNOON. STILL SOME SPOTTY CONVECTION POPPING UP OVER PARTS OF NW AND CNTRL WI. INITIAL MCS HAS ESSENTIALLY STABILIZED THE ATMOSPHERE OVER NE WI THIS AFTERNOON AND EVEN WITH SOME SUNSHINE HEADED INTO THE EARLY EVENING...HARD TO SEE ENUF DESTABILIZATION AHEAD OF THE ADVANCING CDFNT TO ALLOW STORMS TO BECOME SEVERE. STILL EXPECT TO SEE SOME REDEVELOPMENT OF SHWRS AND/OR TSTMS THIS EVENING AS THE SHORTWAVE TROF/CDFNT MOVE THRU...THUS WL NEED TO CARRY A POP THRU THE EVENING BEFORE PCPN TRENDS DIMINISH FROM WEST TO EAST OVRNGT. DRIER AIR WL BEGIN TO OVERSPREAD THE REGION BEHIND THE FNT AND THIS SHOULD PREVENT ANY MORE FOG FROM DEVELOPING (INCLUDING THE LAKESHORE). HAVE LOWERED MIN TEMPS A COUPLE OF DEGS WHICH WL ALLOW FOR PARTS OF N-CNTRL WI TO DIP INTO THE MID TO UPR 50S...WHILE E-CNTRL WI HOLDS IN THE MID 60S. STILL A BIT OF CYCLONIC FLOW HANGS ON TO NE WI TUE MORNING AS THE SHORTWAVE TROF BEGINS TO PULL AWAY FROM THE REGION. HOWEVER...AS AN AREA OF HI PRES BUILDS INTO THE WRN GREAT LAKES DURING THE COURSE OF THE DAY...A GENERAL DECREASE IN CLOUDS WL BE OBSERVED WITH MORE SUNSHINE FOR THE AFTERNOON. A CONTINUATION OF DRIER AIR ADVECTING INTO THE AREA WL SEND DEW POINTS INTO THE 50S (IF NOT A FEW UPR 40S LATE OVER THE NORTH) WITH SLIGHTLY COOLER AIR ARRIVING. LOOK FOR MAX TEMPS TO REACH MAINLY THE 75 TO 80 DEG RANGE. .LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY ISSUED AT 227 PM CDT TUE JUL 9 2013 QUIET WX EXPECTED FOR AT LEAST A COUPLE DAYS AS CANDIAN HIGH PRESSURE SETTLES INTO THE RGN. BLEND OF BIAS-CORRECTED GUIDANCE PRODUCTS NORMALLY PERFORMS WELL FOR MAX/MIN TEMPS WELL UNDER SUCH CIRCUMSTANCES...SO RELIED ON THAT FOR THE FCST. MAIN QUESTIONS IN LATER PERIODS ARE HOW QUICKLY THINGS WARM BACK UP AND WHEN PCPN CHCS RETURN. STILL BELIEVE GUIDANCE IS TOO SLOW TO REACT TO WARMING TEMPS ALOFT...AND THAT HIGHS WELL INTO THE 80S ARE LIKELY BY THE UPCOMING WEEKEND. THE OTHER ISSUE IS WHETHER OR NOT THE UPPER HIGH WL BE CLOSE ENOUGH TO PROTECT THE FCST AREA FM GETTING CLIPPED BY CONVECTION ASSOC WITH SHRTWVS RIDING THROUGH THE MAIN BAND OF WESTERLIES TO THE N. AT THIS POINT...SEEMS AT LEAST CHC POPS ARE WARRANTED. MUCH OF THE MED RANGE GUIDANCE...AND ESP THE NEW ECMWF...ARE TRENDING TOWARD NEAR HEAT WAVE CONDITIONS FOR MUCH OF NEXT WEEK. && .AVIATION...FOR 18Z TAF ISSUANCE ISSUED AT 107 PM CDT TUE JUL 9 2013 DYING LINE OF CONVECTION OVER NRN/ERN WI WL CONT TO PUSH EAST WITH CLEARING TO MOVE BACK INTO THE REGION LATER THIS AFTERNOON. CIGS/VSBYS TO LWR INTO THE MVFR CATEGORY FOR A BRIEF TIME BEFORE RECOVERING TO VFR. THE CDFNT ITSELF WL NOT PASS THRU THE AREA UNTIL MID TO LATE EVENING...THUS CANNOT RULE OUT SHWR/ TSTM REDEVELOPMENT. IF THESE STORMS CAN FIRE...POTENTIAL STILL EXISTS FOR GUSTY WINDS...TORRENTIAL DOWNPOURS AND MVFR CIGS/ VSBYS. OTHERWISE...GRADUAL IMPROVING CONDITIONS EXPECTED FOR WED AS HI PRES BEGINS TO BUILD INTO WI. && .MARINE... ISSUED AT 227 PM CDT TUE JUL 9 2013 HAVE EXTENDED THE MARINE DENSE FOG ADVY THROUGH 09Z/WED DUE TO THE VERY HIGH DEW POINTS ADVECTING OVER THE COOLER WATERS OF LAKE MI. WEB CAMS/OBSERVATIONS CONTINUE TO SHOW AREAS OF DENSE FOG FROM DEATHS DOOR TO STURGEON BAY TO SHEBOYGAN. ONCE THE CDFNT CLEARS THE REGION AFTER MIDNGT AND WINDD SWITCH TO THE W-NW...THE FOG SHOULD FINALLY CLEAR. && .GRB WATCHES/WARNINGS/ADVISORIES...
