Area forecast discussion, Jun 14, 2:55 AM CST, 9 hours 34 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 355 AM CDT SUN JUN 14 2009 .SHORT TERM...TODAY THROUGH MONDAY... SPLIT FLOW PATTERN CONTINUES OVER THE WEST. OVER THE WESTERN LAKES... SHORT WAVE TROF OVER ONTARIO TO SHIFT EAST THROUGH AREA TODAY WHILE BUILDING RIDGE OVER THE PLAINS SHIFTS EAST. ISOLATED SHOWER/TSTM ACTIVITY CONTINUES TO STRETCH FROM MN INTO NORTHERN WI...ALONG AXIS OF INSTABILITY. MODELS CONTINUE TO INDICATE THIS AREA TO SHIFT SOUTH INTO CENTRAL AND EAST CENTRAL WI BY THIS AFTERNOON. WILL GO WITH ISOLD WORDING WITH WEAK BOUNDARY/WINDSHIFT IN AREA. SOME MOISTURE CONVERGENCE ALONG BOUNDARY...THOUGH THINK MODELS A BIT HIGH WITH DEW POINT MORE LIKELY INTO MID 50S. EVEN SO WILL SEE SBCAPES OF 500 AND LIS DOWN TO -2. GFS SHOWING SOME DIVERGENCE WITH RRQ OF EXITING JET. WBZERO VALUES LOW THOUGH SHEAR LIMITED. SMALL HAIL POSSIBLE WITH THE STORMS THAT DO DEVELOP. HIGH PRESSURE BUILDS SOUTH INTO LOWER MI TONIGHT WITH EASTERN WI UNDER LIGHT EAST FLOW. HAVE BROUGHT TEMPS UP TO AROUND 80 IN CENTRAL WI FOR MONDAY...THOUGH COOLER EAST WITH FLOW OFF LAKE. .LONG TERM...MONDAY NIGHT THROUGH FRIDAY. UPPER RIDGING WILL HOLD FOR MONDAY NIGHT ACROSS THE REGION...BUT A UPPER TROUGH WILL QUICKLY APPROACH FROM THE NORTHERN PLAINS ON TUESDAY. MODELS STILL A LITTLE DIFFERENT WITH THIS FEATURE...AS THE GFS IS STRONGER WITH A 500MB CLOSED LOW OVER MINNESOTA BY 12Z WEDNESDAY. THIS IS SLOWER THAN ITS PREVIOUS RUN WHICH HAD A STRONGER LOW AND PLACED IT OVER WISCONSIN...SO SEEMS THE GFS IS TRENDING TOWARD THE ECMWF. THE ECMWF IS MUCH WEAKER WITH THE SYSTEM WITH A WEAKER TROUGH PASSING THROUGH THE REGION TUESDAY NIGHT AND WEDNESDAY. THE ECMWF DOES BRING PRECIP A BIT FARTHER NORTHEAST INTO THE CWA THAT WHAT IS CURRENTLY FORECAST...BUT THINKING THE DRIER AIR WILL HOLD OFF FOR MOST/ALL OF TUESDAY...SO PLAN TO KEEP THE LOW/SLIGHT CHANCE CONFINED TO THE SOUTHWEST CWA. NAM AND GFS ENSEMBLE ARE FAIRLY SIMILAR TO THE ECMWF. THE GFS DOES HAVE SOME SUPPORT WITH THE 00Z CANADIAN...WHICH IS A BIT WORRISOME...AS IT BRINGS IN PRECIP TO MUCH OF NORTHEAST WISCONSIN BY 00Z WEDNESDAY. THE CANADIAN WAS ONE OF THE SLOWER MODELS 2 MODEL RUNS AGO...SO WILL NOT JUMP ON THAT CHANGE JUST YET. WITH THE GFS/CANADIAN A LITTLE JUMPY RUN TO RUN...WILL FAVOR THE ECMWF FOR THIS FORECAST PACKAGE. THE CURRENT FORECAST HAS A PRETTY GOOD HANDLE THE ECMWF SCENARIO WITH THE BEST CHANCES FOR SHOWERS AND STORMS ON TUESDAY NIGHT/EARLY WEDNESDAY AND AGAIN ON THURSDAY NIGHT...SO WILL NOT MAKE ANY MAJOR CHANGES. TEMPERATURES WILL BE DEPENDENT ON WHICH SOLUTION IS CORRECT. IF THE GFS/CANADIAN ARE CORRECT...FORECAST HIGH TEMPS ARE SEVERAL DEGREES TOO WARM AS AN UPPER TROUGH WILL LINGER OVER THE WESTERN GREAT LAKES...AND WOULD NEVER GET INTO A SUSTAINED SOUTH/SOUTHWEST FLOW AND WE WOULD BE STUCK WITH PLENTY OF PRECIP/CLOUDS. IF THE ECMWF IS CORRECT...WE SHOULD WARM UP NICELY AHEAD OF THE SYSTEM AT THE END OF THE WEEK. && .AVIATION...VFR CONDITIONS WILL CONTINUE INTO MONDAY...WITH EXCEPTION OF ISOLATED TSTM ACTIVITY. WEAK FRONTAL BOUNDARY/WIND SHIFT TO MOVE SOUTH INTO INCREASINGLY UNSTABLE ATMOSPHERE OVER CENTRAL AND NORTHEAST WI TODAY. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && TE/BERSCH
