...SIGNIFICANT WINTER STORM TO IMPACT THE UPPER MISSISSIPPI
RIVER VALLEY THIS WEEKEND...

.A STRENGTHENING LOW PRESSURE SYSTEM WILL MOVE SLOWLY EAST
THROUGH THE CENTRAL PLAINS FRIDAY NIGHT AND SATURDAY. AHEAD OF
THIS STORM SYSTEM...PRECIPITATION WILL LIKELY DEVELOP ACROSS THE
UPPER MISSISSIPPI RIVER VALLEY FRIDAY NIGHT AND CONTINUE INTO
SATURDAY. PRECIPITATION WILL LIKELY BE A MIX OF SNOW...SLEET...AND
FREEZING RAIN SOUTHWEST OF A LAKE CITY MINNESOTA TO WISCONSIN
DELLS LINE...AND MAINLY IN THE FORM OF SNOW NORTHEAST OF THIS
LINE. DUE TO THE POTENTIAL MIX OF PRECIPITATION ACROSS SOUTHEAST
MINNESOTA...NORTHEAST IOWA...AND SOUTHWEST AND WEST CENTRAL
WISCONSIN...EVENTUAL SNOW AND ICE ACCUMULATIONS ARE VERY
UNCERTAIN. MEANWHILE IT APPEARS THAT THERE WILL BE THE POSSIBILITY
OF 4 TO 8 INCHES OF SNOW ACROSS CENTRAL AND NORTH CENTRAL
WISCONSIN.

AS THE STORM SYSTEM MOVES NORTHEAST THROUGH THE MID MISSISSIPPI
RIVER VALLEY ON SATURDAY NIGHT AND SUNDAY...ADDITIONAL
ACCUMULATING SNOW MAY FALL ACROSS SOUTHEAST MINNESOTA...NORTHEAST
IOWA...AND WESTERN WISCONSIN. IF IT APPEARS THAT ADDITIONAL SIGNIFICANT
SNOWS MAY FALL FROM THIS SYSTEM...THIS WATCH MAY HAVE TO BE
CONTINUED INTO SUNDAY.

AMOUNTS MAY BE IN THE 4 TO 8 INCH RANGE. ADDITIONAL ACCUMULATING
SNOW MAY FALL SATURDAY NIGHT AND SUNDAY. THIS STORM SHOULD ALSO
HAVE STRONG WINDS DURING THE WEEKEND...WHICH WOULD ADD TO THE
POTENTIAL FOR HAZARDOUS TRAVELING CONDITIONS. IF THE POTENTIAL
FOR SEVERE WINTER WEATHER IMPACTS TO LINGER THROUGH THE WEEKEND...THIS
WATCH MAY HAVE TO BE EXTENDED INTO SUNDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
339 PM CST WED FEB 21 2007

.SHORT TERM...THROUGH SUNDAY
SHORT TERM PORTION OF DISCUSSION WILL INCLUDE SUNDAY SINCE MAJOR
STORM SYSTEM STILL LINGERS INTO THIS DAY...AND WITH THIS SYSTEM
THE FORECAST FOCUS...DECIDED TO INCLUDE THIS ENTIRE TIME PERIOD IN
THIS PORTION OF DISCUSSION.

NO DOUBT THAT SIGNIFICANT EVENT BECOMING A BIGGER AND BIGGER
THREAT FOR THIS CWA...BUT DETAILS MAGNIFIED AS A LOWER CONFIDENCE
ITEM DUE TO PROXIMITY OF THERMAL RIBBON AND HUGE VARIATION IN
P-TYPE AND ASSOSCIATED HAZARDS.

FIRST THINGS FIRST...A RATHER POTENT WAVE ALONG MN/CANADA BORDER
WILL DIG SOUTHEAST TONIGHT INTO THE GREAT LAKES. STRONG COLD
FRONT TO WHOOSH THROUGH THE CWA THIS EVENING. TOYED HEAVILY WITH
ISSUING A WIND ADVISORY FOR THE EVENING PERIOD...BUT DECIDED THAT
ADVISORY CRITERIA WILL ONLY BE TOUCHED BRIEFLY AT A FEW LOCATIONS.
STRONG COLD ADVECTION COINCIDES WITH THE ISALLOBARIC COUPLET AND
40KT 925MB FLOW TO ALLOW A FEW POTENT GUSTS THIS EVE...ESPECIALLY
WIND PRONE AREAS OF NRN 1/2 OF CWA...NAMELY SERN MN AND RIDGETOPS
OF MS RVR VALLEY...AND OUT INTO THE FLATS NEAR SPARTA/TOMAH. BAND
OF SPRINKLES/VERY LIGHT SHOWERS ALONG FRONT WILL CROSS NRN CWA
THROUGH 00Z BUT SHOULD NOT BE PROBLEM FOR TONIGHT/S FORECAST GIVEN
OVERWHELMING SUBSIDENT SIGNAL AS NIGHT WEARS ON.

MUCH COOLER TOMORROW DESPITE PLENTY OF SUNSHINE...AND WEAKENING
WINDS. RIDGE AXIS TO PASS OVER AREA THURS NIGHT WITH CALM WINDS
AND MAINLY CLEAR SKIES. DROPPED TEMPS A BIT BOTH THUR AND THUR
NIGHT GIVEN STRONGER COLD ADVECTION SIGNAL...AND GOOD RADIATIONAL
POTENTIAL THURS NIGHT.

LARGE STORM SYSTEM FRIDAY NIGHT THROUGH SUNDAY...TRIED AS MUCH AS
POSSIBLE TO KEEP FINE DETAIL OUT OF THE FORECAST...GIVEN HOW
WIDELY VARYING THE OUTCOMES COULD BE ACROSS OUR AREA. WHAT WE FEEL
FAIRLY CONFIDENT ON...IS THAT SIGNIFICANT PCPN SEEMS A GOOD BET
ACROSS MUCH OF THE AREA. THIS IS IN WIDE AGREEMENT FROM THE
DETERMINISTIC RUNS OF GFS/WRF/ECMWF/CANADIAN...WITH SUPPORTING
VERY HIGH PROBABILITIES IN SREF/GEFS. WE ARE LOOKING
/CONSERVATIVELY/ AT 0.75 TO 1.25 INCHES...WITH AN UPSIDE OF 2.00
INCHES POSSIBLE IF IDEAL THERMODYNAMIC/KINEMATIC FORCING
MECHANISMS CAN LINK UP OVER A PORTION OF THE AREA FOR A DECENT
PERIOD OF TIME.

HPC STANDARDIZED ANOMALIES INDICATE THAT ANOMALOUS MOISTURE FLUX
OF GREATER THAN 4.0 STANDARD DEVIATIONS AHEAD OF VERY DEEP AND
POTENT WAVE TO MOVE OUT OF SRN ROCKIES THIS WEEEKEND. THIS DEEP
WAVE ALLOWS SFC PRESSURES TO LOWER TO ABOUT 985 MB SAT AFTN BEFORE
OCCLUSION AND RAPID FILLING OF THE SYSTEM ALOFT. MOISTURE INDEED
WILL BE PLENTIFUL...AND GIVEN IMPRESSIVE THERMODYNAMIC LIFT FIRST
/FRIDAY NIGHT INTO SATURDAY MORNING/ AND THEN KINEMATIC LIFT AS
THE MAIN UPPER SYSTEM MOVES RIGHT AT US SATURDAY NIGHT...TWO
SIGNIFICANT WAVES OF PCPN IN THE OFFING. FIRST BAND OF PCPN FRIDAY
NIGHT ON NOSE OF VERY IMPRESSIVE WARM ADV/ISENTROPIC LIFT
SIGNAL...AND SHOULD SPREAD INTO CWA FRI EVENING...FOCUSING IN WRN
CWA. GIVEN MAINTENANCE OF E-SELY FLOW IN LOW LEVELS OUT OF GREAT
LAKES HIGH...THINK BOUNDARY LAYER WARMING IS GOING TO BE LESS THAN
PVSLY ANTICIPATED. THUS...THINK FREEZING/FROZEN PCPN MAY BE BIGGER
THREAT...WITH DECENT ACCUMULATIONS POSSIBLE FOR WRN AREAS FRI
NIGHT. HOWEVER...BAROCLINIC RIBBON TEETERING VERY CLOSE BY...AND
CAN/T DISCOUNT POSSIBILITY THAT MIX/RAIN BECOMES JUST AS BIG OF A
THREAT GIVEN ANY WOBBLE IN FCST MODEL SOLNS. THIS ESPECIALLY TRUE
INTO SATURDAY WHEN WARMING POTENTIAL IS AT ITS GREATEST.
MAINTAINED THE POSSIBILTIES OF EITHER RAIN OR SNOW INTO SATURDAY.

ENTIRE SYSTEM BEGINS TO FILL SATURDAY NIGHT INTO SUN PASSING BY TO
OUR SOUTH. INCREASING SIGNAL THAT COLD ADV TO INCREASE SAT NIGHT
INTO SUN TAKING ALL BACK OVER TO SNOW...WITH POTENTIAL OF
SIGNIFICANT ACCUMS. VERY DYNAMIC/DEEP LIFT SATURDAY NIGTH PROMISES
THE HEAVIEST PD OF PCPN. THIS A WIDELY DISPLAYED AND AGREED UPON
SOLN IN THE VARIOUS ENSEMBLES/DETERMINSITIC RUNS.

HAVE NO DOUBT THAT WINTER STORM WATCHES WILL MOST LIKELY BE
HOISTED IN NEXT SHIFT OR TWO...ONCE DIFFERENT PCPN TYPES CAN BE
SINGLED OUT AND HAZARDS CAN BE IDENTIFIED. WHAT WE DON/T WANT...TO
LEAN TOO HEAVILY ON ANY ONE TYPE OF PCPN TOO FAR OUT...SO DIDN/T
HAVE CONFIDENCE TODAY TO GO WITH WATCH. TOO MUCH UNCERTAINTY OF
ALL LIQUID CHANCES ESP SAT...BEFORE TRANSITIONING BACK TO FROZEN.
MAINTAIN THAT THIS SYSTEM COULD PRODUCE VERY SIGNIFICANT
ICING/SNOW ACCUMULATIONS...OR FLOODING IF MAINLY RAIN FALLS ON
FROZEN SOILS. THIS ALL ADDRESSED IN CURRENT HAZARDOUS WEATHER
OUTLOOK...AND EXTENDED HYDROLOGIC PRODUCT.

.LONG TERM...MONDAY THROUGH WEDNESDAY
MUCH QUIETER AND SEASONABLE PERIOD. EYES WILL QUICKLY FOCUS NEXT
ON THE NEXT SIGNIFICANT CHUNK OF ENERGY DUE INTO THE AREA BY END
OF NEXT WEEK. WILL NEED TO LOOK AT THAT MORE WHEN WE GET THIS
CURRENT SYSTEM PAST US. COULD SPELL ANOTHER ROUND OF ACTIVE
WEATHER.

300 PM CST WED FEB 21 2007

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

.DAY ONE...TONIGHT

A STORM SYSTEM PASSING ACROSS LAKE SUPERIOR TONIGHT WILL BRING
STRONG WEST AND NORTHWEST WINDS TO PARTS OF THE AREA TONIGHT. WIND
SPEEDS OF 15 TO 25 MPH WITH GUSTS TO AROUND 35 MPH CAN BE EXPECTED
FOR LOCATIONS ALONG AND NORTH OF INTERSTATE 90...ESPECIALLY FROM MID
EVENING THROUGH THE OVERNIGHT HOURS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

IT IS BECOMING MORE CERTAIN THAT A POTENT STORM SYSTEM WILL BRING A
WINTRY MIX OF PRECIPITATION TO THE UPPER MIDWEST...BEGINNING FRIDAY
NIGHT AND LASTING THROUGH THE BULK OF THE WEEKEND. HOWEVER...THE
DETAILS REMAIN UNCERTAIN...WITH LOWER CONFIDENCE ON WHAT TYPE OF
PRECIPITATION WILL FALL. TEMPERATURES ALOFT ARE IN THE CRITICAL
RANGES THAT THE PRECIPITATION COULD BE RAIN...FREEZING RAIN...SLEET
OR SNOW FOR MUCH OF THE AREA...DEPENDING ON SUBTLE SHIFTS IN THE
EXPECTED TRACK OF THE STORM. WHAT SEEMS THE MOST CERTAIN IS THAT
SIGNIFICANT AMOUNTS OF PRECIPITATION WILL FALL...WITH THE THREAT OF
FLOODING...SIGNIFICANT ICE ACCUMULATION...OR HEAVY SNOW ALL
POSSIBLE.

IF THE STORM LIFTS FURTHER NORTH THAN PRESENTLY EXPECTED...MORE RAIN
WOULD RESULT AND THE THREAT OF RUNOFF AND SIGNIFICANT RISES IN AREA
RIVERS WHICH ARE STILL ICE COVERED WOULD BE THE PRIMARY CONCERN. THE
RISING WATER WOULD BREAK UP THE ICE ON THE RIVERS...AND MAY CREATE
ICE JAMS. A MORE SOUTHERLY TRACK OF THE LOW PRESSURE WOULD BRING
ENOUGH COLD AIR INTO THE STORM SYSTEM BY SATURDAY NIGHT AND SUNDAY
THAT MOST OF THE PRECIPITATION WOULD BE SNOW...WITH SIGNIFICANT
ACCUMULATIONS. A PROLONGED PERIOD OF MIXED PRECIPITATION IS ALSO
POSSIBLE...WITH THE POTENTIAL FOR SIGNIFICANT ICING. FURTHER YET...
STRONG WINDS MAY RESULT IN CONSIDERABLE BLOWING AND DRIFTING OF ANY
NEW SNOW BY SUNDAY. THOSE WITH TRAVEL PLANS FRIDAY NIGHT THROUGH
SUNDAY ACROSS THE ENTIRE AREA SHOULD STAY TUNED TO YOUR FAVORITE
SOURCE OF WEATHER INFORMATION FOR UPDATES ON THE DETAILS OF THIS
POTENTIAL WINTER STORM.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED. HOWEVER PRECIPITATION REPORTS
WOULD BE GREATLY APPRECIATED THIS WEEKEND.

.EMERGENCY MANAGEMENT COORDINATION...

NO CALL IS SCHEDULED.
