AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
342 PM CDT SUN JUN 10 2007

.DISCUSSION...
UPPER AIR PATTERN BEGINNING TO AMPLIFY THIS AFTERNOON AS UPPER LOW
CENTERED JUST OFF THE CENTRAL BRITISH COLUMBIA COAST PUSHES A TROUGH
INTO THE U.S. PACIFIC NORTHWEST. THIS IS EXPECTED TO PHASE WITH
CUTOFF UPPER LOW OFF THE BAJA COAST AND CONTINUE TO AMPLIFY UPPER
RIDGING FROM THE ARKLATEX THROUGH THE WESTERN GREAT LAKES AND UP
THROUGH JAMES BAY INTO TUESDAY.

LOW-MID LEVEL THETA-E ADVECTION AND ASSOCIATED ISENTROPIC ASCENT
TRIGGERING CLUSTER OF THUNDERSTORMS ACROSS THE FAR SW CWA ATTM.
THE MAIN THREAT WITH THESE STORMS THROUGH THE NEXT SEVERAL HOURS
WILL BE DAMAGING WIND GUSTS AND LARGE HAIL. ANOTHER AREA OF
ISENTROPIC ASCENT EXITS ACROSS THE CENTRAL CWA FROM JUST NORTHWEST
OF THE MSP METRO EASTWARD INTO WEST CENTRAL WI. SATELLITE SHOWS AN
ENHANCED AREA OF CU ASSOCIATED WITH THIS SO HAVE INCLUDED SLIGHT
POPS THRU THE EVENING. NOT MUCH CHANGE IN THE ATMOSPHERE TOMORROW
WITH TEMPS ONCE AGAIN IN THE UPPER 80S TO AROUND 90. WILL ONCE
AGAIN BE ON THE EASTERN EDGE OF MOIST ADVECTION/ASCENT WITH
UNSTABLE CONDITIONS. BEST MOISTURE TRANSPORT IS FOCUSED JUST TO
THE WEST SO WILL NEED TO WATCH FOR ISOLATED STORM POTENTIAL AGAIN.
LOW LEVEL JET INCREASES MONDAY EVENING...ESPECIALLY JUST TO THE
NORTHWEST OF THE CWA...WHICH WILL BRING SHOWER AND THUNDERSTORM
DEVELOPMENT WHICH MAY IMPACT THE FAR NORTHWEST CWA MONDAY NIGHT.

THE PACIFIC NW UPPER TROUGH ATTEMPTS TO MOVE INTO THE EASTERN
DAKOTAS WEDNESDAY WITH THE GFS ATTEMPTING TO DEVELOP A WEAK CLOSED
SFC LOW ACROSS SOUTH DAKOTA WHICH WASHES OUT ACROSS THE CWA
WEDNESDAY NIGHT. THE ECMWF SHOWS MORE OF A WEAK INVERTED TROUGH
FEATURE MOVING ACROSS AS DOES THE NAM-WRF. REGARDLESS...TUESDAY
NIGHT INTO THURSDAY MAY BE THE BEST CHANCE AT PRECIPITATION ACROSS
THE WESTERN AND CENTRAL CWA WITH UPPER TROUGH IN THE AREA AND WEAK
ISENTROPIC ASCENT AHEAD OF IT...POTENTIALLY LIFTING OVER WHAT
REMAINS OF A SFC BOUNDARY LEADING TO POTENTIAL FOR HEAVY RAIN. WILL
NEED TO MONITOR TO FURTHER PIN DOWN THE DETAILS. THE
BOUNDARY/UPPER TROUGH WEAKENS/PULLS AWAY THURSDAY. ANOTHER UPPER
LOW ENTERS THE PACIFIC NORTHWEST EARLY FRIDAY HELPING TO ESTABLISH
UPPER RIDGE AXIS OVER THE AREA AND KEEPING TEMPERATURES ABOVE
NORMAL FOR THE WEEKEND. ..MDB..

.AVIATION.../FOR 18Z TAF CYCLE/
LITTLE EVIDENT IN THE WAY OF FORCING MECHANISMS...BUT INSTABILITY
AND MOISTURE BEST IN SW MN...GRADUALLY SPREADING INTO WC MN. HAVE
INDICATED CHC SHOWERS AT RWF LATE AFTERNOON AND EVENING... AND A BIT
LATER FOR AXN. THERE WILL BE SOME STORMS BUT NOT ON A SEEMINGLY
