AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
403 AM CDT SAT JUN 13 2009

.SHORT TERM...TODAY THROUGH SUNDAY...

SPLIT FLOW PATTERN CONTINUES OVER U.S. CHANGE THIS PERIOD IS SHIFT
TO NW UPPER FLOW OVER WESTERN LAKES AS RIDGE BUILDS INTO PLAINS.
QUESTION OF FORECAST AGAIN IS PCPN CHANCES AS WAVES WORK SOUTHEAST
OUT OF CANADA THROUGH NORTHERN BRANCH OF FLOW.

AREA RADAR SHOWING LIGHT RAIN OVER SOUTHERN WI MAKING STEADY
PROGRESS TO THE EAST...EXITING SOUTHERN CWA BY 12Z. SECOND AREA
OF MORE SCATTERED SHOWERS MOVING THROUGH MN ARROWHEAD. MORE
SHOWERS FURTHER WEST ALONG SFC FRONT/TROF IN NORTH DAKOTA. SECOND
AREA OF PCPN ASSOCIATED WITH NEXT WAVE THAT IS EXPECTED TO PASS
THROUGH NORTHERN WI LATE AFTN/EVENING. AXIS OF INSTABILITY/
MOISTURE CONVERGENCE LOCATED OVER NORTHERN WI LATE THIS AFTERNOON.
LIMITED DYNAMICS AS WAVE WEAKENS...THOUGH DO HAVE SOME WEAK WAA
FOCUSED OVER NORTHERN COUNTIES. MADE LITTLE CHANGE FROM PREVIOUS
FORECAST...STAYING WITH CHANCE POPS FOR THIS AFTERNOON AND
EVENING.

ON SUNDAY...MODELS SHOWING SURFACE FRONT SHIFTING SLOWLY SOUTH
THROUGH THE CWA. INCREASING INSTABILITY WITH TEMPS IN THE UPPER
70S SHOULD ALLOW FOR SMALL CHANCE OF SHOWERS ALONG BOUNDARY. ADDED
FOR LATE AFTERNOON OVER CENTRAL AND EAST CENTRAL WI.

BLEND OF NAM AND GFS GUIDANCE LOOKS GOOD FOR TEMPS THIS PERIOD.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY.

QUIET WEATHER WILL START OFF THE LONG TERM AS SURFACE HIGH
PRESSURE AND UPPER RIDGING WILL PASS THROUGH THE REGION. THE
RIDGING WILL BREAK DOWN BY TUESDAY MORNING AS A SHORTWAVE WILL
APPROACH FROM THE CENTRAL PLAINS. DECENT MOISTURE MOVES BACK INTO
NORTHEAST WISCONSIN BY TUESDAY AFTERNOON...BRINGING IN THE CHANCE
FOR SHOWERS AND THUNDERSTORMS...ESPECIALLY ACROSS THE SOUTHWEST
CWA. TIMING STILL AN ISSUE WITH THE ONSET OF PRECIP CHANCES...BUT
WILL KEEP HIGHER POPS ON TUESDAY NIGHT AND WEDNESDAY AS THE
SHORTWAVE MOVES THROUGH.

BRIEF PERIOD OF RIDGING MOVES OVERHEAD ON WEDNESDAY NIGHT AND
EARLY THURSDAY...BUT WITH TIMING ISSUES...WILL NOT TAKE OUT THE
MENTION OF SHOWERS AND STORMS JUST YET AS IT IS POSSIBLE EITHER OF
THESE PERIODS COULD HAVE SOME SCATTERED SHOWERS ACTIVITY. ANOTHER
SHORTWAVE WILL SWING TROUGH THE UPPER GREAT LAKES...BRINGING
ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS FOR THE END OF THE
WORK WEEK.

TEMPERATURES ARE EXPECTED TO BE NEAR OR SLIGHTLY ABOVE NORMAL
ACROSS MUCH OF THE AREA FOR MOST OF THE LONG TERM...WITH READINGS
APPROACHING THE 80 DEGREE MARK ACROSS CENTRAL WISCONSIN. THE ONLY
EXCEPTION TO THE MORE SUMMER-LIKE TEMPERATURES WILL BE NEAR LAKE
MICHIGAN WERE THE PERSISTENT EASTERN COMPONENT OF THE SURFACE WIND
WILL KEEP TEMPERATURES IN THE MID TO UPPER 50S.
&&

.AVIATION...VFR CONDITIONS CONTINUE THROUGH PERIOD...WITH FEW
AREAS OF MVFR CONDITIONS WITH FOG EARLY THIS MORNING CENTRAL
SITES. SCATTERED SHOWERS AND A CHANCE FOR TSTM THIS AFTERNOON INTO
SUN AS FRONTAL SYSTEM SLOWLY MOVES SOUTH THROUGH THE REGION.
&&

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