AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
300 AM CDT WED JUN 8 2011

.SHORT TERM...TODAY THROUGH THURSDAY. CONVECTIVE POTENTIAL AND
HIGH TEMPERATURES ARE THE MAIN FOCUS FOR THIS FORECAST. WISCONSIN
IS IN THE WARM SECTOR OF A SURFACE LOW PRESSURE SYSTEM OVER
NORTHERN MINNESOTA AT 08Z TODAY. A LOW LEVEL JET IS HELPING TO
PRODUCE SCATTERED THUNDERSTORMS OVER CENTRAL WISCONSIN. THIS
ACTIVITY SHOULD MOVE INTO THE EAST CENTRAL PORTION OF THE STATE BY
DAYBREAK. BEING ELEVATED AND DIURNAL IT SHOULD DIMINISH SHORTLY
AFTER SUNSET.

IT SHOULD BE ANOTHER HOT AND SOMEWHAT HUMID DAY AGAIN TODAY. HIGHS
IN THE UPPER 80S TO LOW 90S LIKELY OVER ALL BUT THE LAKESHORE.
DEW POINTS IN THE 60S WILL COMBINE WITH AFTERNOON HIGHS TO PRODUCE
HEAT INDICES BETWEEN 85 AND 95. A COLD FRONT WILL MOVE ACROSS THE
AREA DURING THE LATE AFTERNOON AND EVENING HOURS. A SCATTERED TO
BROKEN LINE OF THUNDERSTORMS SHOULD ACCOMPANY THE FRONT WITH SOME
POTENTIAL OF SEVERE WEATHER.

THE FRONT WILL BE FOLLOWED BY MUCH COOLER AND DRIER AIR THURSDAY.
HIGHS WILL BE ABOUT 10 DEGREES BELOW NORMAL INSTEAD OF 10 TO 20
DEGREES ABOVE NORMAL.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY
MAIN CONCERN DURING FORECAST PERIOD WILL BE TRYING TO TIME
THE CHANCES FOR SHOWERS AND THUNDERSTORMS. ON THURSDAY NIGHT...
WARM FRONT WILL BE PUSHING NORTHWARD TOWARDS WISCONSIN. THURSDAY
EVENING SHALL BE DRY WITH INCREASING CHANCES FOR SHOWERS AND
THUNDERSTORMS SOUTH AND WEST OF A WAUSAU TO MANITOWOC LINE. ALTHOUGH
SOME SIGNIFICANT TIMING DIFFERENCES BETWEEN 00Z WRF/12Z ECMWF AND THE
00Z GFS/CANADIAN...HAVE TRENDED TOWARD THE QUICKER WRF/ECMWF
SOLUTION. LOOKING AT THE CONVECTIVE PARAMETERS ON FRIDAY...FURTHER
NORTH WARM FRONT AND OVER RUNNING SITUATION SHOULD BRING THUNDERSTORM
ACTIVITY TO THE SOUTHERN HALF OF THE FORECAST AREA. ADDED THUNDERSTORMS
TO THE FORECAST ON FRIDAY. HIGH TEMPERATURES ON FRIDAY A CHALLENGE THIS
MORNING DEPENDING ON QUICKLY PRECIPITATION ARRIVES. SOME LOCATIONS
MAY NOT GET OUT OF THE MIDDLE AND UPPER 50S. A SHARP CONTRAST TO THE
MIDDLE AND UPPER 90S ON TUESDAY.

THE ACTIVITY SHOULD SCATTERED OUT FRIDAY NIGHT...THEREFORE ONLY
CHANCE POPS ARE WARRANTED. SOME INSTABILITY SHOWERS MAY LINGER INTO
SATURDAY OVER THE FAR EAST BEFORE HIGH PRESSURE AND DRIER AIR
WORKS INTO THE REGION.  THE SYSTEM FOR EARLY NEXT WEEK APPEARS SLIGHTLY
SLOWER WITH PRECIPITATION ARRIVING ON MONDAY. DID NOT GET TO SEE
THE
&&

.AVIATION...SCATTERED THUNDERSTORMS EXPECTED EARLY TODAY MAINLY
SOUTH OF A WAUSAU TO GREEN BAY LINE. ADDITIONAL SHOWERS AND
THUNDERSTORMS EXPECTED THIS AFTERNOON AND EVENING AS A COLD FRONT
MOVES THROUGH THE REGION.

&&

.MARINE...SOME MARINE FOG POSSIBLE TODAY AS AIR WITH 60S DEW POINTS
FLOW OVER THE COLD WATER OF LAKE MICHIGAN. TO DAYS WINDS SHOULD
HAVE ENOUGH OF A WESTERLY COMPONENT TO KEEP MOST OF THE FOG AWAY
FROM SHORE. GUSTY SOUTHWEST WINDS WILL BE SUFFICIENT FOR A SMALL
CRAFT ADVISORY.

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
