AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
234 AM CDT TUE AUG 2 2011

.SHORT TERM...TODAY/TONIGHT/WEDNESDAY. THE TODAY PORTION WILL BE
THE PRIMARY FOCUS DUE TO ONGOING CONVECTION FROM CENTRAL WISCONSIN
TO NORTHEAST MINNESOTA EARLY THIS MORNING. AT 08Z SCATTERED
SHOWERS AND STORMS WERE ALREADY IN CENTRAL AND NORTH CENTRAL
WISCONSIN BUT RADAR TRENDS INDICATE THIS CONVECTION HAS WEAKENED
WHILE DRIFTING SLOWLY NORTHEAST. HOWEVER THE CONVECTION OF NOTICE
IS THE CONVECTION AROUND DULUTH. SAT IMAGERY INDICATE THE COLDEST
CLOUD TOPS WERE IN THIS REGION. LATEST MODEL RUNS INDICATE THIS
CONVECTION IS PROGGED TO SLIDE OVER UPPER MICHIGAN AND PERHAPS
NORTHERN WISCONSIN ALONG OR NEAR THE WARM FRONT DURING THE MORNING
HOURS. HOWEVER THE CAP EDGE AND BEST INSTABILITY EXTENDS FROM THE
DULUTH AREA TO CENTRAL WISCONSIN TO SUGGEST A POTENTIAL SOUTHEAST
DEVELOPMENT INTO CENTRAL WISCONSIN THIS MORNING. THIS TREND HAS
WARRANTED A SEVERE THUNDERSTORM WATCH FOR MUCH OF CENTRAL AND
NORTH CENTRAL WISCONSIN THIS MORNING. PRIMARY THREATS APPEAR TO BE
DAMAGING WINDS AND HEAVY RAIN DUE TO VERY HIGH PWATS. FREEZING
LEVEL RATHER HIGH TO DECREASE THE HAIL THREAT. WILL ADJUST PRECIP
CHANCES AS PER RADAR TRENDS THIS MORNING.

COULD HAVE A BRIEF DIMINISHED PERIOD OF CONVECTION AFTER THIS MCS
COMPLEX PASSES PRIOR TO ANOTHER ROUND OF CONVECTION ALONG THE
COLD FRONT TOWARD THE AFTERNOON HOURS. SCT SVR STORMS WERE NOTED
OVER EASTERN DAKOTA THIS MORNING ALONG OR NEAR THE COOL FRONT.
THIS FRONT APPEARS TO BE LAGGING A BIT SO WILL ADD AN ISOLD
CONVECTION MENTION INTO THE TUESDAY EVENING HOURS OVER THE FAR
EAST.

HIGH PRESSURE SYSTEM TO DRIFT OVER TONIGHT INTO WEDNESDAY TO
PROVIDE A LITTLE COOLER AND DRIER INTO THE REGION.

.LONG TERM...WEDNESDAY NIGHT THROUGH SATURDAY NIGHT.

PERSISTENT SUB-TROPICAL RIDGING OVER THE CENTRAL PLAINS AND
MID-MISSISSIPPI VALLEY WILL GRADUALLY BECOME MORE SUPPRESSED AS WE
HEAD INTO THIS WEEKEND.  WILL HAVE A COUPLE CHANCES OF PRECIP OVER
THIS PERIOD INCLUDING LATE THURSDAY NIGHT INTO FRIDAY MORNING...AND
ALSO SATURDAY AND SATURDAY NIGHT.  BLENDED THE ECMWF AND GFS FOR
THIS FORECAST.

WEDNESDAY NIGHT THROUGH THURSDAY NIGHT...WILL HAVE SHORTWAVE RIDGING
ALOFT AND HIGH PRESSURE AT THE SURFACE INITIALLY ON WEDNESDAY
EVENING.  GUIDANCE HAS COME IN COOLER AND HAVE DROPPED TEMPS A
COUPLE DEGREES UP NORTH.  MID AND HIGH CLOUDS GRADUALLY INCREASE ON
THURSDAY AHEAD OF A SHORTWAVE TROUGH MOVING INTO THE CENTRAL
MISSISSIPPI VALLEY AND ANOTHER WAVE MOVING OVER CENTRAL CANADA.  LOW
LEVELS WILL REMAIN DRY THANKS TO THE LINGERING HIGH PRESSURE.  THE
MID-MISSISSIPPI WAVE WILL MOVE INTO NORTHERN ILLINOIS THURSDAY
NIGHT...WHILE THE CANADIAN WAVE WILL DRIVE A COLD FRONT INTO
NORTHWEST WISCONSIN LATE.  SOME LIGHT PRECIP MAY REACH INTO CENTRAL
WISCONSIN LATE THURSDAY NIGHT FROM THE SOUTHERN WAVE.  BETTER
FORCING WILL STAY TO THE SOUTH...SO WILL JUST KEEP A SMALL CHANCE OF
SHOWERS IN THE FORECAST.

FRIDAY THROUGH SATURDAY NIGHT...SOME SHOWERS MAY LINGER OVER
EAST-CENTRAL WISCONSIN FRIDAY MORNING...BUT SHOULD SEE PRECIP MOSTLY
MOVE OUT BY THE AFTERNOON.  THE FRONT SAGGING IN FROM THE NORTH
LOOKS TO WASH OUT ON FRIDAY...LEAVING A MOSTLY DRY FRIDAY AFTERNOON
AND FRIDAY NIGHT.  PRECIP CHANCES RETURN SATURDAY AND SATURDAY NIGHT
WHEN RETURN FLOW DEVELOPS AHEAD OF THE NEXT SHORTWAVE MOVING OVER
THE NORTHERN PLAINS.  WILL INCREASE POP CHANCES SATURDAY AND
SATURDAY NIGHT.  HIGHS IN THE LOW TO MID 80S.  LOWS IN THE UPPER 50S
TO MIDDLE 60S.
&&

.AVIATION...SCT MVFR CIGS AND VSBYS EXPECTED TODAY WITH STORMS.
STORMS WILL BE MORE NUMEROUS OVER NORTHERN WISCONSIN AND PARTS OF
CENTRAL WISCONSIN THIS MORNING. VFR CONDITIONS TO DOMINATE
TONIGHT WITH PATCHY MVFR VSBYS DUE TO FOG LATE TONIGHT.
