AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 310 AM CDT WED JUL 2 2008 .SYNOPSIS...UPR FLOW ACRS NOAM WL REMAIN FAIRLY AMPLIFIED EARLY IN THE FCST PERIOD AS SHRTWV DIGS SE ACRS THE GREAT LAKES RGN. THE TREND AFTER THAT WL BE FOR THE FLOW TO DEAMPLIFY...THOUGH THE MEAN TROF AND RIDGE POSNS WL LIKELY REMAIN IN PLACE INTO NEXT WK. STARTING TO GET SOME SIGNALS FM THE MED RANGE MODELS THAT UPR RIDGE WL EXPAND/SHIFT NEWD INTO THE CENTRAL OR POSSIBLY EVEN ERN PART OF THE COUNTRY LATER NEXT WK AND BEYOND. IF THAT OCCURS IT WOULD RESULT IN VERY SUMMER-LIKE WX WITH HOT AND HUMID CONDITIONS SPREADING ACRS THE AREA. BUT GIVEN RELATIVE STABILITY OF CURRENT PATTERN...NEED TO SEE A LITTLE STRONGER/CLEARER SIGNAL TO HAVE MUCH CONFIDENCE IN GETTING A PATTERN CHANGE. TEMPS WL DROP TO BLO NORMAL EARLY IN THE FCST PERIOD AS ANOTHER SHOT OF CANADIAN AIR IS DELIVERED INTO THE AREA IN THE WAKE OF SHRTWV DIGGING ACRS THE RGN. READINGS SHOULD REBOUND FOR THE WEEKEND AND NEXT WK. LOOKS LIKE THERE WL BE TWO MAIN CHCS OF PCPN DURING THE PERIOD. FIRST WL BE TDA AS SHRTWV DIGS IN AND DRIVES A COLD FRONT ACRS THE RGN. SECOND WL BE LATE IN THE WEEKEND OR EARLY NEXT WK. EXPECT THAT MOST AREAS WL END UP BLO NORMAL ON PCPN FOR THE NEXT 7 DAYS. && .SHORT TERM...TDA/TNGT/THU. COLD FRONT NOW INTO NW WI. LOCAL MESO PLOTS INDICATED AREA OF MUCAPE SHIFTG SEWD INTO THE FCST AREA AHEAD OF THE FRONT. 925 MB WINDS ALSO APPEAR TO BE INCRG AND SUPPORTING PRETTY STG CONVERGENCE NR THE FRONT. EXPECT TSRA TO CONTINUE TO DEVELOP NR THE FRONT AS IT PUSHES ACRS THE AREA TDA. WOULD EXPECT UPTICK IN STRENGTH/COVERAGE LATE THIS MORNING/THIS AFTN AS ATM IN THE WARM SECTOR STARTS TO DESTABILIZE. GREATEST RISK OF SVR WL BE OVER THE SRN/SERN 1/2 OF THE FCST AREA...WHERE FRONT WL BE THIS AFTN. WL MAKE ISSUANCE TIME DECISION ON WHETHER OR NOT TO INCLUDE EXPLICIT SVR IN GRIDS/ZONES. NAM AND TO SOME EXTENT THE OTHER MODELS INDICATED THE POSSIBILITY OF SFC WV DEVELOPING ON THE FRONT OVER E-C WI THIS AFTN. THAT WOULD SLOW THE FRONT AND INCREASE THE POSSIBILITY OF SOME CONVECTION DEVELOPING BACK OVER THE FRONTAL SFC. FOR THAT REASON WL HOLD POPS INTO THE EARLY EVENING OVER THE SERN PART OF THE FCST AREA...THEN HAVE CLEARING SKIES AS CANADIAN AIR MASS RUSHES INTO THE RGN. WENT BLO GUID FOR MINS ACRS THE N. CU RULE OFF THE MODELS SUGGESTED BKN CU ON THU...BUT THAT DOES NOT SEEM TO FIT WITH BEING UNDER COOLER AND DRIER CANADIAN AIR MASS WITH UPR JET AXIS OFF TO THE NE. MODELS MAY BE HOLDING ONTO TOO MUCH LOW-LEVEL MOISTURE AGAIN...SO WENT WITH LOWER SKYCON IN THE GRIDS. .LONG TERM...FRIDAY THRU TUESDAY. UPPER RIDGE EDGES E DURING FIRST PART OF PERIOD...WHICH WILL ALLOW TEMPS TO INCREASE DAILY THRU WEEKEND. BEFORE THE WARM-UP... CANADIAN HIGH PRESSURE...WHICH PUSHES IN BEHIND WEDNESDAYS FROPA...WILL SLOWLY MOV ACRS STATE. WITH HIGH OVER STATE ON FRIDAY MORNING...MIN TEMPS XPCTD TO BE 5 TO 10 DEGS BLO NORMAL. ADJUSTED TEMPS DOWN A BIT IN PREFERRED COLD SPOTS FROM PREV FCST. DAYTIME TEMPS SHOULD REBOUND QUICKLY WITH EARLY JULY SUNSHINE AND RELATIVELY LOW HUMIDITY. LOW HUMIDITY WILL ALSO ALLOW MIN TEMPS TO STAY NEAR OR BLO NORMS THRU SAT MORNING. SFC RIDGE MOVES E OF STATE SUN AS SHORTWV TROF APPROACHES FROM THE W. WITH RESPECT TO SPEED OF SHORTWV...02/00Z GFS OP APPEARS TO BE RIGHT BETWEEN THE 01/12Z GFS ENSEMBLE AND 01/12Z ECMWF...AND CLOSE TO CURRENT FCST. FLOW TURNS MORE ZONAL BEHIND SHORTWV TROF WITH LARGE...FLAT UPPER RIDGE ACRS SRN HALF OF U.S. OVERALL...LITTLE CHG NEEDED TO PREV FCST PKG FOR THIS PD. && .AVIATION...LLWS WL DISSIPATE EARLY TDA WE START TO MIX OUT. SCT TSRA WL CONT ACRS THE RGN. WL PROBABLY HAVE THUNDER IN THE TAFS FOR THE PERIOD RIGHT ARND FROPA AT AUW/CWA/GRB.
