AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
256 PM CDT SAT SEP 3 2005

.SHORT TERM...TONIGHT THROUGH TUESDAY

FORECAST FOCUS IS ON RAIN CHANCES TONIGHT INTO SUNDAY...AND AGAIN ON
TUESDAY. WARMER TEMPERATURES ALSO OF INTEREST.

19Z SURFACE ANALYSIS SHOWS HIGH PRESSURE EXTENDING NORTH-SOUTH FROM
ONTARIO DOWN ACROSS WI INTO IL. VISIBLE SATELLITE IMAGERY SHOWING
AN IMPRESSIVE CONVECTIVE COMPLEX ACROSS CENTRAL MN...AND A SEVERE
THUNDERSTORM WATCH HAS JUST BEEN ISSUED. THIS COMPLEX DEVELOPED
OVER ND LAST NIGHT ON THE NOSE OF THE BEST ELEVATED MOISTURE
TRANSPORT/CONVERGENCE...AND HAS SURVIVED NEARLY 24 HOURS FEEDING
OFF THIS SAME SUPPORT.  REGIONAL RADAR LOOPS SHOW THIS CONVECTION
NORTH OF A LINE FROM OWATONNA TO LAKE CITY TO MONDOVI AT 230 PM.
SOUTH AND EAST PORTIONS HAVE WEAKENED...BUT WESTERN AREAS ARE
RAMPING UP AGAIN WHERE THE BEST FORCING SUPPORT REMAINS.

12Z 03SEP05 MODEL SOLUTIONS IN REASONABLE AGREEMENT WITH THE MASS
FIELDS...AND EVEN THE QPF...ALTHOUGH NONE HAVE A PARTICULARLY GOOD
HANDLE ON THE CURRENT CONVECTIVE ACTIVITY.  GFS IN PARTICULAR SEEMS
TO BE OVER-DOING THE MCV DEVELOPING WITH THIS ACTION...AND MAY HAVE
A BIT TOO MUCH QPF.  LEANING MORE TOWARD THE NAM.

SHOWERS AND THUNDERSTORMS TO CONTINUE TO REGENERATE THROUGH THE
EVENING OVER WESTERN MN WHERE THE BEST MOISTURE TRANSPORT...
INSTABILITY...AND SHEAR REMAIN FOCUSED.  THIS SUPPORT DOES TRANSLATE
EAST TOWARD THE FORECAST AREA TONIGHT...AND STEERING FACTORS WOULD
FOCUS OVER OUR AREA.  AS SUCH...HAVE RAISED POPS AND WORDING INTO
THE CATEGORICAL RANGE.  CANNOT COMPLETELY RULE OUT THE POTENTIAL FOR
SOME MARGINALLY SEVERE HAIL AND WIND...BUT DEEP MOISTURE SUPPORT IS
LACKING.  FORECAST SOUNDINGS CONFIRM THE LACK OF DEEP MOISTURE...BUT
THIS DRY AIR MAY ASSIST A WIND THREAT.  CURRENT WATCH BOX IS JUST
WEST/NORTH OF THE FORECAST AREA...AND RUNS THROUGH 9 PM. PREVIOUS
FORECASTER ALSO NOTED THE POTENTIAL FOR SOME STORM TRAINING...AS
THE ANCHOR POINT OF THE FORCING/DEVELOPMENT AREA LIES PERPENDICULAR
TO THE EXPECTED STORM PROPAGATION.  SOME LOCALIZED HEAVIER AMOUNTS
ARE POSSIBLE IN NORTHWEST TO SOUTHEAST FASHION SOMEWHERE ALONG THE
MISSISSIPPI RIVER VALLEY REGION.

EXPECT THE CONVECTIVE COMPLEX TO SHIFT EAST INTO WI/IL BY MORNING...
TAKING THE RAIN THREAT SLOWLY WITH IT.  UPPER RIDGE THEN BUILDS AHEAD
OF THE NEXT SHORT WAVE. SOUTHERLY WINDS INCREASE AGAIN IN ADVANCE OF
THIS SYSTEM..AND THIS SHOULD HELP TEMPERATURES TO WARM NICELY. EXPECT
TEMPERATURES TO GET ABOVE NORMAL FOR SUNDAY AND MONDAY...AND THIS WAS
HANDLED IN THE PREVIOUS FORECAST.

LOW PRESSURE AREA ASSOCIATED WITH THE NEXT SHORT WAVE TROUGH WILL
DEEPEN OVER ND BY MONDAY...AND THIS LOW WILL MOVE NORTHEAST INTO
WESTERN ONTARIO MONDAY NIGHT.  COLD FRONT TRAILING THE LOW...ALONG
WITH A LOBE OF THE SHORT WAVE TROUGH AND MOISTURE TRANSPORT INTO
THE BOUNDARY...SHOULD RESULT IN A LINE OF CONVECTION ALONG THE
FRONT.  FRONT SHOULD MARCH EAST THROUGH THE AREA TUESDAY.

.LONG TERM...TUESDAY NIGHT THROUGH NEXT SATURDAY

MEDIUM RANGE MODELS ARE AT ODDS AT MID WEEK...WITH SOME SOLUTIONS
FAVORING A WEAKER AND FURTHER NORTH SOLUTION...WHICH HANGS THE
FRONTAL BOUNDARY UP OVER NORTHERN IL AND IA TUESDAY NIGHT THROUGH
THURSDAY...WHILE OTHER SOLUTIONS DRIVING THE FRONT FURTHER SOUTH.
WITH THE AREA UNDER THE MEAN UPPER RIDGE AXIS...THE WEAKER AND
FURTHER NORTH SOLUTION HAS SOME MERIT...BUT MORE MEMBERS POINT TO A
FURTHER SOUTH SOLUTION.  FOR NOW HAVE NOT MADE TOO MANY CHANGES IN
THE EXTENDED PERIOD...BUT STARTED TO BRIDGE THE GAP WITH THE
ALIGNMENT OF SOME OF THE GRIDDED FIELDS.  THIS WILL BEAR WATCHING IN
THE COMING DAYS.

RETURN FLOW AS A STRONGER SHORT WAVE MOVES ACROSS THE INTERMOUNTAIN
WEST FOR THE LAST HALF OF THE WEEK SHOULD RESULT IN A CHANCE FOR
MORE CONVECTION BY FRIDAY.

.ARX WATCHES/WARNINGS/ADVISORIES...
WI...NONE.

526 AM CDT SAT SEP 3 2005

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PARTS OF SOUTHEAST
MINNESOTA...NORTHEAST IOWA...AND SOUTHWEST AND WEST CENTRAL
WISCONSIN.

.DAY ONE...TODAY AND TONIGHT

A WARM FRONT SHIFTING NORTH THROUGH MINNESOTA WILL PROVIDE FOR
ACTIVE WEATHER OVERNIGHT. SHOWERS AND THUNDERSTORMS COULD OCCUR ALONG
THE FRONT IN CENTRAL MINNESOTA TODAY...HOWEVER A LARGER COMPLEX OF
THUNDERSTORMS IS EXPECTED TO DEVELOP OVER EASTERN MINNESOTA NEAR
MINNEAPOLIS BY MID-EVENING. THUNDERSTORMS ARE EXPECTED TO THEN MOVE
AND DEVELOP SOUTHEAST...INTO SOUTHEASTERN MINNESOTA AND WESTERN
WISCONSIN AFTER 9 PM TONIGHT. ALTHOUGH THE MOST FAVORABLE INSTABILITY
AND WIND SHEAR FOR SEVERE STORMS IS CLOSER TO MINNEAPOLIS...A FEW
STORMS AFFECTING AREAS NORTHWEST OF A LINE FROM AUSTIN MINNESOTA TO
LA CROSSE WISCONSIN...TO MARSHFIELD...COULD BE SEVERE. THE MAIN
THREATS ARE LARGE HAIL AND DAMAGING WINDS. AREAS SOUTH OF THAT LINE
COULD SEE STORMS...HOWEVER THE MAIN THREAT WOULD BE HEAVY RAIN.

THIS COMPLEX MAY HOLD NEARLY STATIONARY FOR A NUMBER OF HOURS...
REGENERATING THUNDERSTORMS ALONG A BROAD LINE CENTERED ON THE
MISSISSIPPI RIVER. THIS MEANS MANY STORMS COULD AFFECT THE SAME
AREA...POSING A HEAVY RAINFALL THREAT...RESULTING IN LOCALIZED
FLOODING.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

MORE SCATTERED STORMS WILL BE POSSIBLE TUESDAY WHEN A COLD FRONT
MOVES INTO THE AREA.  THIS FRONT COULD STALL ACROSS THE AREA
PROVIDING THUNDERSTORMS WEDNESDAY AS WELL. IT STILL REMAINS TOO
EARLY TO DETERMINE THE SEVERE POTENTIAL WITH THESE STORMS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS LOOKING LIKELY TONIGHT...BETWEEN 9 PM AND
2 AM...ACROSS SOUTHEAST MINNESOTA AND WESTERN WISCONSIN. MOST
LIKELY SPOTTERS NEAR AND NORTH OF I-90 WOULD BE CALLED UPON.

.EMERGENCY MANAGEMENT COORDINATION...

NO CALL IS SCHEDULED.
