AREA FORECAST DISCUSSION

400 AM CDT WED JUN 14 2006

.DISCUSSION...
CONVECTION CONTINUES TO FIRE UP ALONG OUR SOUTHWESTERN THIRD OF CWA
EARLY THIS MORNING. ACTIVITY ASSOCIATED WITH MODERATE STRENGTH VORT
LOBE AND RIGHT REAR QUAD OF 90KT JET COUPLET. MODEL OF CHOICE THIS
GO AROUND HAS TO BE NAM/ETA DUE TO ALMOST PINPOINT ACCURACY IN
ALIGNING CURRENT CONVECTION AND PLACEMENT OF 50H RIDGE OVER
INTERMOUNTAIN WEST AND 50H RIDGE DIPPING INTO GREAT LAKES REGION.
USING 310K ISENTROPIC CHART ALONG WITH 700-500MB Q VECTOR
CONVERGENCE TO ALIGN TIMING AND LIKELIHOOD OF PCPN FOR REMAINDER OF
THE DAY. A 250MB DIVERGENCE COUPLET WILL EXIT SOUTHERN CWA BY LATE THIS
MORNING. THIS SHOULD SQUELCH MUCH OF ORGANIZED PCPN...ESPECIALLY
OVER SW FA. BEST CHANCE FOR SCT CONVECTION SHOULD WILL CONTINUE
ACROSS FAR SOUTH CENTRAL MN INTO LATE THIS AFTERNOON...WITH ENOUGH
LIFT AND MOISTURE IN PLACE TO MENTION SLT POPS INTO METRO AND PORTION
OF WI ZONES DURING LATE AFTERNOON AND INTO EARLY EVENING. INCREASED
TEMPS LIGHTLY INTO FRIDAY ASSOCIATED WITH INCREASED 850 TEMPS...AND
MODERATE SOUTHERLY FLOW AHEAD OF SURFACE WAVE ENTERING EASTERN
DAKOTAS BY 15/12Z. SLOW PROGRESSION OF SYSTEM WARRANTS MENTION OF
CHANCE POPS RIGHT INTO SATURDAY. CHANCE PCPN STARTED OVER FAR
WESTERN CWA TONIGHT...AS 850MB JET SETS UP NICELY ACROSS THIS REGION
BY 06Z. MAIN FOCUS FOR SHOWERS AND THUNDERSTORMS SWITCHING TO
EASTERN HALF OF CWA DURING MORNING HOURS ON THURSDAY...IN
ASSOCIATION WITH BEST MOISTURE VALUES...QG FORCING AND ONE VERY
HEALTHY 250MB DIVERGENCE COUPLET. BEST CHANCE FOR CONVECTIVE
FIREWORKS ONCE AGAIN SLATED FOR THU NIGHT...ESPECIALLY BETWEEN 06
AND 12Z...AS NOSE OF 100KT JET TREKS INTO WEST CENTRAL MN. IMPRESSIVE
DIVERGENCE COUPLET SETS UP ACROSS SOUTHERN QUARTER OF MN AND EXTREME
SOUTHERN WI CWA.  850MB JET EVEN STRONGER THIS TIME FRAME...SO WILL LOOK
FOR VERY STRONG TO SEVERE THUNDERSTORMS FORMING ROUGHLY SOUTH OF LINE
FROM MONTEVIDEO TO ST PAUL...TO DUNN WI. WITH DIRECTIONAL COMPONENT OF
LOW LEVEL JET FROM SW...APPEARS ANY ORGANIZED SEVERE WEATHER THAT
MATERIALIZES SHOULD BE OF A WIND AND HAIL VARIETY. COOL FRONT WEAKENS
AND SLOWS APPRECIABLY ON FRIDAY...AS JET AXIS BECOMES PARALLEL TO SAME.
COOL FRONT BASICALLY STALLS FROM SW MN TO NE WI LATE FRIDAY
AFTERNOON...AND FINALLY BEGINS TO EXIT FAR EASTERN CWA BY LATE
SATURDAY.

LONGER TERM...SATURDAY THROUGH TUESDAY NIGHT
UPPER AIR PATTERN WILL REMAIN IN TRANSITION AS THE NORTHERN BRANCH
OF THE JET STREAM LIFTS NORTH OVR CANADA DURING THE PERIOD.  LONG
TERM MODELS ARE IN SOME DISAGREEMENT IN THE OVERALL SOLUTION DURING
THE PERIOD. THUS CONFIDENCE IN THE FORECAST IS RATHER LOW...WITH
BOTH THE SURFACE AND UPPER LEVEL FEATURES RATHER WEAK. THE LATEST
GFS MAINTAINS A ZONAL FLOW OVER THE NORTHERN CONUS WITH A SERIES OF
SHORT WAVE TROUGHS AND IMPLUSES PASSING OVER THE UPPER MIDWEST OVER
THE WEEKEND. THE 00Z/14TH ECMWF MODEL RUN HAS THE JET STREAM FURTHER
NORTH DURING THE PERIOD...WHICH WILL BRING MUCH OF THE UPPER MIDWEST
INTO THE DOLDRUMS OF SUMMER. TEMPERATURES WILL BECOME THE MAIN
CHALLENGE DURING THE PERIOD.
