AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 350 PM CDT FRI JUL 11 2008 .SHORT TERM...TONIGHT AND SATURDAY...MAIN FCST CONCERNS ARE PCPN TRENDS AND POTENTIAL FOR SVR TSTMS TONIGHT...THEN TEMPS AND ARRIVAL OF MUCH DRIER AIR ON SATURDAY. MAIN WARM FRONT WAS STILL SITUATED SW OF GRB CWA THIS AFTERNOON... BUT APPEARED TO BE REORGANIZING OVER N IL. THIS BOUNDARY SHOULD SHIFT STEADILY NORTH INTO GRB CWA THIS EVG...AS SOUTHERLY FLOW INCREASES IN ADVANCE OF THE APPROACHING NORTHERN PLAINS COLD FRONT. CAPPING INVERSION IS VERY STG OVER EASTERN MN...WHERE TAMDAR SOUNDINGS SHOW 700 MB TEMPS AROUND +12 TO +13 C...BUT IS WEAKER OVER GRB CWA...WHERE 19Z TAMDARS SHOW +9 TO +10 C. WITH THE LLJ INCREASING THIS EVG...THE WARM FRONT LIFTING THROUGH...AND OUR AREA SITUATED ON THE EASTERN PERIPHERY OF THE CAP...THINK THAT SCT TSTMS WILL REDEVELOP THIS EVG. ISOLD SVR STORMS ARE PSBL...WITH DAMAGING WINDS THE PRIMARY THREAT. LATER TONIGHT...MODELS SHOW CONVECTION ASSOC WITH THE APPROACHING COLD FRONT REACHING OUR NW COUNTIES TOWARD MIDNIGHT...THEN SHIFTING EAST AND GRADUALLY WEAKENING OVERNIGHT. THIS SEEMS REASONABLE...GIVEN THE UNFAVORABLE TIMING OF THE FROPA...AND THE MAIN UPPER LEVEL FORCING STAYING TO OUR NW. WILL MAINTAIN LIKELY POPS FOR THE ENTIRE CWA...WITH HIGHEST POPS IN OUR NW COUNTIES. SVR THREAT SHOULD BE CONFINED TO NC/C WI DURING THE VERY LATE EVG AND EARLY MORNING HOURS. ON SATURDAY...CONTINUED THE PREVIOUS FCST OF LINGERING POPS IN OUR SE COUNTIES DURING THE MORNING...THEN DRY FOR THE AFTERNOON. MUCH DRIER AIR WILL ADVECT INTO THE CWA ON GUSTY WEST WINDS. AVG MIXING RATIOS IN THE BOUNDARY SUPPORT DEW POINTS FAILLING INTO THE MID 40S ACROSS NC WI DURING THE AFTERNOON. DEEP MIXING THROUGH 800-750 MB YIELDS MAX TEMPS IN THE UPPER 70S TO MIDDLE 80S. .LONG TERM...SAT NGT THRU NXT FRI. MAIN STORM TRACK TO CONT RUNNING ALONG THE NRN TIER OF STATES NXT WEEK AS A SPRAWLING SUBTROPICAL UPR RDG SETS UP SHOP OVR THE SRN CONUS. AN UPR TROF IS EXPECTED TO DROP SWD TOWARD BRITISH COLUMBIA WHICH MAY LIFT THE MAIN STORM TRACK FARTHER NORTH BY LATE WEEK. AFTER A QUIET START TO THE WORK WEEK...PCPN CHCS WL BECOME A CONCERN OVR NE WI AS A FNTL BNDRY HANGS AROUND THE RGN. WEDGE OF DRY AIR/SUBSIDENCE WL PREVENT ANY PCPN FROM AFFECTING NE WI SAT NGT. THERE WL BE SOME INCREASE IN CLDS OVR NRN WI LTR SAT NGT AS WRAP-AROUND MSTR FROM THE ONTARIO UPR LOW ROTATES THRU THAT PART OF THE STATE. AS A RESULT...HAVE RAISED MIN TEMPS A COUPLE OF DEGS OVR NRN AND PARTS OF CNTRL WI. WRAP-AROUND MSTR PEELS AWAY FROM NRN WI SUNDAY MORNING LEAVING THE RGN BETWEEN THE DEPARTED SFC LOW WELL TO OUR NE (JAMES BAY) AND WEAK HI PRES OVR THE CNTRL CONUS. THERE WAS A CONCERN THAT THE WRN GREAT LKS COULD DESTABILIZE ENUF TO ALLOW A WEAK SHRTWV TO KICK OFF A SHWR OR TWO. AT THIS POINT...THAT SHRTWV IS PROGGED BY THE MDLS TO REMAIN VERY WEAK AND WITH NO OTHER FOCUSING MECHANISMS PRESENT OR MUCH MSTR AVBL (DEW PTS IN THE 40S/50S)...PREFER TO GO DRY FOR THE ENTIRE FCST AREA ON SUNDAY. EXPECT BREEZY CONDITIONS WITH SUSTAINED WNDS OF 15 TO 20 MPH ACCOMPANIED BY HIGHER GUSTS. THAT WEAK SFC HI IS EXPECTED TO RDG INTO THE WRN GREAT LKS SUNDAY NGT AND PROVIDE FOR CLEARING SKIES AND DIMINISHING WNDS. THIS SHOULD BRING GOOD RADIATIONAL COOLING CONDITIONS TO NE WI AND PREFER THE COOLER MAV GUID FOR MIN TEMPS. THE SFC HI OVR THE WRN GREAT LKS AT THE START OF THE WORK WEEK WL GRADUALLY SLIDE TOWARD THE ERN GREAT LKS BY MON NGT AND INTO THE MID-ATLANTIC STATES BY TUE AFTERNOON. A PLEASANT...COMFORTABLE DAY FOR MON WITH NORMAL TEMPS AND RELATIVELY LOW R.H.S. AS WE GET ON THE BACKSIDE OF THE DEPARTED HI PRES ON TUE...A WARMER/MORE MOIST AIRMASS TO RETURN TO NE WI. HAVE KEPT BOTH MON AND TUE DRY. ATTN TURNS TO THE NRN PLAINS/UPR MIDWEST WHERE A CDFNT IS PROGGED TO SLOWLY BE MOVG SEWD. THERE ARE TIMING DIFFERENCES AMONG THE MDLS WITH THE GFS RACING THE FNT THRU TUE NGT...THE ECMWF/UKMET HOLDING THE FNT OFF TIL WED AND THE GEM EVEN SLOWER. THE ENSEMBLE MEAN FAVORS THE ECMWF/UKMET SOLN SO PREFER TO BRING A SLGT CHC OF SHWRS/TSTMS TO NE WI TUE NGT WITH CHC POPS THEN FOR WED AS THE FNT APPROACHES. BIG QSTNS REMAIN FOR THE LTR PART OF NXT WEEK WITH REGARDS TO THE POSITIONING OF THE FNTL BNDRY. THE FNT IS EXPECTED TO SLOW DOWN OR EVEN GRIND TO A HALT AS IT ENCOUNTERS THE SUBTROPICAL RDG. IT APRS THAT THE FNT IS STILL IN OUR VCNTY THRU THU...THUS WL NEED TO CARRY CHC POPS AT LEAST THRU THE END OF THU. AS AN UPR TROF DIGS SWD TOWARD THE PAC NW BY NXT FRI AND A WEAK UPR RDG BUILDS OVR THE ROCKIES...THE MEAN FLOW MAY TURN ENUF TO THE W-NW TO KICK THE FNT FARTHER SOUTH. THAT BEING SAID...TIMNIG IS VERY SUSPECT THIS FAR OUT. PREFER TO LINGER A SML POP THRU FRI UNTIL THIS TIMING ISSUE CLRS UP. TEMPS FOR LATE IN THE WEEK SHOULD BE CLOSE TO NORMAL. && .AVIATION...WARM FRONT WILL LIFT NORTH ACROSS THE AREA THIS EVG. PATCHY MVFR CIGS MAY DEVELOP NORTH OF THIS BOUNDARY...ALONG WITH SCT TSTMS. THUNDERSTORMS WILL INCREASE IN C/NC WI TOWARD MIDNIGHT AS THE COLD FRONT APPROACHES FROM THE WEST. THESE STORMS ARE EXPECTED TO WEAKEN SOMEWHAT AS THEY SHIFT EAST OVERNIGHT. THE COLD FRONT WILL MOVE OUT THE FCST AREA SATURDAY MORNING...TAKING ANY PCPN WITH IT. MUCH DRIER AIR WILL MOVE INTO THE RGN ON SATURDAY...LEADING TO VFR CONDITIONS. GUSTY WEST WINDS ARE EXPECTED SATURDAY AFTERNOON. && .MARINE...HAVE ISSUED A SMALL CRAFT ADVISORY FOR TONIGHT INTO SATURDAY MORNING. 925 MB WINDS INCREASE TO 40-45 KTS OVER LK MICH TONIGHT...SO DESPITE THE STABLE MARINE LYR...S-SW WINDS SHOULD INCREASE TO AT LEAST 15-25 KTS AFTER THE WARM FRONT MOVES THRU. INCREASING GULF MOISTURE WILL LIKELY ALSO LEAD TO MARINE FOG DEVELOPMENT TONIGHT. LOCALLY DENSE FOG IS PSBL. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && KIECKBUSCH/KALLAS
