The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Green Bay, WI wrote its last area forecast discussion before the first event at Jun 27, 2:12 PM CST, 3 hours 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 312 PM CDT MON JUN 27 2011 .SHORT TERM...TONIGHT AND TUESDAY. THUNDERSTORMS ARE THE MAIN CONCERN DURING THIS PART OF THE FORECAST...MAINLY EARLY IN THE FIRST PERIOD. SHOWERS AND ISOLATED THUNDERSTORMS FROM EARLY THIS MORNING FADED AWAY...NEVER PRODUCING PRECIPITATION IN THE FORECAST AREA. ENOUGH THIN SPOTS AND BREAKS IN THE CLOUDS TODAY ALLOWED FOR DESTABILIZATION ACROSS WISCONSIN AHEAD OF THE COLD FRONT MOVING INTO THE AREA FROM MINNESOTA. AT MIDDAY/EARLY AFTERNOON STORMS DEVELOPED IN A COUPLE OF AREAS OF LOW LEVEL MOISTURE CONVERGENCE. ONE WAS IN THE SOUTHEAST PART OF THE STATE AND THE OTHER WAS OVER WESTERN WISCONSIN. DEVELOPMENT IN THE SOUTHEAST APPEARED TO BE DYING OFF AS OF 1930Z WHILE A MORE CONTIGUOUS LINE OF CONVECTION CONTINUED TO DEVELOP IN WESTERN WISCONSIN WHERE THERE WAS LITTLE TO NO CIN AND SB CAPE VALUES EXCEEDED 1000 J/KG. STILL NO EXPLOSIVE DEVELOPMENT...NO WARNINGS IN THE WESTERN PART OF WISCONSIN AND NO SPC MESOSCALE DISCUSSION FOR THAT AREA. 0-6 KM SHEAR IN THE AREA WITH THE CONVECTION WAS IN THE 30 TO 40 KT RANGE WHILE THE MAX VALUES LAGGED BEHIND IN MINNESOTA. THE LATEST WATER VAPOR IMAGERY INDICATED THE UPPER LEVEL TROUGH AXIS WELL BEHIND THE FRONT TOO. NOT LOOKING LIKE AN IDEAL SETUP FOR SIGNIFICANT SEVERE TO DEVELOP...BUT WILL KEEP THE HIGH POPS IN THE GRIDS THROUGH 00Z TUESDAY AND TAPER POPS TO LESS THAN SLIGHT CHANCE CATEGORY BY 06Z TUESDAY. KEPT MUCH OF THE FORECAST SIMILAR TO WHAT WAS ISSUED ON THE MIDNIGHT SHIFT. JUST SOME ADJUSTMENTS TO TEMPERATURES USING COMBINATIONS OF THE PREVIOUS FORECAST AND VARIOUS GUIDANCE VALUES. .LONG TERM...TUESDAY NIGHT THROUGH THE 4TH OF JULY...SMALL PCPN CHCS AND TEMPERATURES WILL BE THE MAIN FCST CONCERNS. HIGH PRESSURE WILL BRING DRY WEATHER THROUGH ABOUT WEDNESDAY NIGHT. A GRADUAL WARMING TREND IS ANTICIPATED...WITH TEMPS WARMING TO AROUND NORMAL BY WEDNESDAY. THE FCST GETS A BIT MORE DIFFICULT LATE IN THE WORK WEEK...AS RETURN FLOW BRINGS A MUCH WARMER...MOISTER AND UNSTABLE AIR MASS INTO THE FA...ALONG WITH A STRONG MID-LEVEL CAP. HAVE ADDED A SMALL POP ON THURSDAY...ALONG THE LEADING EDGE OF THE ELEVATED MIXED LAYER AND MID-LEVEL CAP. HOWEVER...BY THURSDAY EVG...H7 TEMPS ARE EXPECTED TO BE +12 TO +15 C...SO A CAP SHOULD BE FIRMLY IN PLACE. IT'S NOT EVEN A GIVEN THAT THE COLD FRONTAL PASSAGE ON FRIDAY AND FRIDAY NIGHT WILL BE ABLE TO GENERATE CONVECTION...AS THE WARM MID-LEVEL TEMPS ONLY COOL SLIGHTLY. GIVEN THE STRONG INSTABILITY...WILL KEEP A SLIGHT CHC OF TSTMS IN THE FCST... DESPITE THE CAP. FCST H8 TEMPS SUPPORT HIGHS IN THE UPPER 80S TO MID 90S ON FRIDAY. WEAK HIGH PRESSURE BUILDING INTO THE REGION IN THE WAKE OF THE COLD FRONT WILL BRING MORE COMFORTABLE TEMPERATURES IN THE LOWER TO MIDDLE 80S ON SAT/SUN...ALONG WITH DRY CONDITIONS. ANOTHER WEAK COLD FRONT MAY BRING A CHC OF TSTMS ON THE 4TH OF JULY...BUT CONFIDENCE IN THE DETAILS THAT FAR OUT IS LOW. && .AVIATION...EXPECT MAINLY PLENTY OF MVFR CIGS AND SCATTERED VFR CIGS AROUND THROUGH THE LATE AFTERNOON. BUT THE BIGGER CONCERN WILL BE THE LINE OF CONVECTION PUSHING INTO CENTRAL WISCONSIN MID TO LATE THIS AFTERNOON AND CONTINUING ACROSS EASTERN WISCONSIN. SHOULD BE MVFR AND ISOLATED IFR CIGS AND VSBYS WITH THE STORMS IN ADDITION TO STRONG WIND GUSTS. CONDITIONS SHOULD IMPROVE INTO THE VFR CATEGORY BY 06Z...EXCEPT NEAR THE UPPER MICHIGAN BORDER WHERE SOME MVFR CIGS MAY LINGER TOWARD DAWN. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && MG/KIECKBUSCH
