AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
400 AM CDT SAT JUN 11 2005

.SYNOPSIS...CURRENT UPR PATTERN WITH TROF OVER THE W AND RIDGE IN THE E
WL PERSIST INTO EARLY NEXT WK THEN TRANSITION TO AN AMPLIFYING PATTERN
WITH A RIDGE OVER THE PLAINS AND TROFS NR THE COASTS. THE RISK OF
TSTMS...AND SVR WX...WL CONT INTO THE WEEKEND AS THE SW UPR FLOW
MAINTAINS A FEED OF WARM MOIST AIR INTO THE AREA. PCPN CHCS WL CONT INTO
NEXT WK AS UPR SYSTEM LINGERS ACRS THE AREA WHILE THE PATTERN CHG
OCCURS. EXPECT A TREND TOWARD COOLER AND DRIER WX BY LATE NEXT WK/THE
FOLLOWING WEEKEND AS UPR FLOW BECOMES NWLY.

.SYNOPSIS...YDA MORNING THERE WAS A WEAK FRONTAL BOUNDARY ACRS THE FCST
AREA WITH A VERY MOIST AND UNSTABLE AIR MASS IN PLACE JUST S OF THE RGN.
THE MOISTURE RETURNED NWD INTO THE FCST AREA AS DAYTIME HEATING FURTHER
DESTASTABILIZED THE AIR. THAT AIR MASS INTERACTED WITH THE BOUNDARY ACRS
THE AREA AND THE TAIL OF A SHRTWV LIFTG NNEWD W OF THE FCST AREA TO
PRODUCE FAIRLY WIDESPREAD SVR WX.

FRONT STILL LINGERING ACRS THE AREA THIS MORNING...BUT THE MOIST
UNSTABLE AIR WAS NOW ESTABILISHED ACRS THE AREA. SFC PLOTS AND THE 00Z
RAOBS SUGGESTED THAT THE AIR TO THE S WON/T BE QUITE AS UNSTABLE AS YDA.
IT LIKELY WON/T BE VERY WELL CAPPED EITHER...SO THAT WOULD FAVOR MORE
SCT TSTM ACTIVITY TDA...AND A LESSER THREAT OF WIDESPREAD SVR WX. SVR
STORMS STILL POSSIBLE...HOWEVER. THE FCST AREA WAS IN THE SPC DY1 SLGT
RISK OF SVR WX...AND THAT SEEMED REASONABLE. THE MORE TROPICAL AIR WOULD
SUPPORT MAINLY A WIND DAMAGE THREAT.

EXPECT THE SCT STORMS TO CONT INTO TNGT AND THEN DIMINISH. THE MODELS
HINTED AT A SLIGHTLY LESS FAVORABLE SITN FOR PCPN SUN...AS SOMEWHAT
DRIER AIR MAY WORK INTO THE N. NOT ENOUGH EVIDENCE TO REMOVE PCPN FM THE
FCST YET. STILL SEEMS THAT WEAKLY CAPPED UNSTABLE AIR MASS COULD YIELD
SCT AFTN TSTMS. STUCK WITH LOW CHC POPS.

SHRTWV AMPLIFYING IN THE PLAINS SUN NGT/MON LIKELY TO CLOSE OFF AS THE
LARGE SCALE PATTERN CHG GETS UNDERWAY. CLOSED UPR LOW SHOULD THEN WORK
EWD AND EVENTUALLY HELP TO ESTABLISH THE NEW EASTERN NOAM UPR TROF. THE
MODELS WERE STRUGGLING WITH THE HANDLING OF THE SYSTEM IN THE CHANGING
LARGE SCALE PATTERN...AND OFFERED WIDELY VARYING SOLNS ON THE TRACK AND
TIMING OF THE SYSTEM. BROAD BRUSH APPROACH WORKS BEST IN SUCH SITNS.
CONTD CHC OF TSTMS INTO MID-WK...THEN LINGERED JUST SHRA FOR A TIME AS
THE FCST AREA WL BE ON THE BACK SIDE OF THE SYSTEM MID-WK. TRENDED TEMPS
DOWNWARD BY MID-WK. ERN NOAM TROF SHOULD BE WELL ENOUGH ESTABLISHED BY
LATE IN THE WK TO ALLOW CANADIAN HIGH TO BUILD SWD FM HUDSON BAY. TOOK
TEMPS BACK TO AT OR A BIT BLO NORMAL LEVELS...AND WENT WITH A DRY FCST
HEADING INTO NEXT WEEKEND.
