AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
317 PM CST SUN FEB 26 2012

.SHORT TERM...THROUGH WEDNESDAY
317 PM CST SUN FEB 26 2012

MAIN FORECAST CONCERN IS WITH THE PRECIPITATION CHANCES STARTING
TUESDAY.

SURFACE ANALYSIS THIS AFTERNOON SHOWS AN AREA OF LOW PRESSURE OVER
CENTRAL MINNESOTA.

THE LOW OVER MINNESOTA WILL CONTINUE TO MOVE NORTHEAST TONIGHT AND
WILL MAINTAIN A TIGHT PRESSURE GRADIENT OVER THE REGION. THE
STRONGEST WINDS ARE EXPECTED TO OCCUR INTO EARLY THIS EVENING ONCE
THE COLD FRONT MOVES THROUGH AND THE STRONGEST COLD AIR ADVECTION
MOVES ACROSS THE AREA. SUSTAINED WEST WINDS ARE EXPECTED TO BE IN
THE 20 TO 25 KNOT RANGE WITH GUSTS TO AROUND 35 KNOTS. THESE WILL
THEN SLOWLY DIMINISH THROUGH THE REMAINDER OF THE NIGHT AS THE
GRADIENT RELAXES AND THE STRONGEST COLD AIR ADVECTION MOVES EAST
OF THE AREA. NO CHANGES PLANNED TO THE CURRENT WIND ADVISORY.

ATTENTION QUICKLY TURNS TO THE NEXT SYSTEM TO COME IN FOR THE
MIDDLE OF THE WEEK. WATER VAPOR SATELLITE INDICATES THIS IS OFF
THE WEST COAST OVER THE PACIFIC BUT WILL START TO COME ONSHORE
STARTING TONIGHT. ALL THE 26.12Z MODELS CONTINUE TO SHOW GOOD RUN
TO RUN CONTINUITY BUT STILL SOME DIFFERENCES ON THE PLACEMENT OF
THE EVENTUAL TRACK OF THE SYSTEM. THE ECMWF DID COME IN WITH A
SLIGHT NORTHWARD ADJUSTMENT AND WHILE VERY SIMILAR TO THE GFS ON
THE TRACK...IT IS NOW A FEW HOURS SLOWER. THE FORCING WITH THIS
SYSTEM WILL BE QUITE STRONG WITH OVER 30+ PVU/S OF VORTICITY
ADVECTION IN THE 500-300 MB LAYER FOR TUESDAY NIGHT INTO
WEDNESDAY. AS WOULD BE EXPECTED WITH PV ADVECTION THIS
STRONG...THERE WILL BE STRONG AND DEEP QG CONVERGENCE WITH THE
SHORT WAVE TROUGH. WEAK TO MODERATE FRONTOGENESIS WILL SET UP OVER
THE REGION IN THE 1000-700 MB LAYER FOR TUESDAY NIGHT BEFORE
WEAKENING AND MOVING OFF TO THE EAST WEDNESDAY. DURING THE SAME
PERIOD...THERE IS ALSO EXPECTED TO BE MODERATE FN VECTOR
CONVERGENCE IN THE 650-550MB LAYER. THE ISENTROPIC UP GLIDE WILL
MAX OUT AROUND 14 UBAR/S ON THE 290K SURFACE TUESDAY NIGHT AS
WELL. GIVEN ALL THE FORCING...PRECIPITATION ACROSS THE AREA SEEMS
A CERTAINTY AND HAVE STARTED WITH UP TO 60 PERCENT CHANCES ACROSS
THE WEST TUESDAY AFTERNOON WITH 90 TO 100 PERCENT ACROSS THE
ENTIRE AREA TUESDAY NIGHT AND THEN 60 TO 80 PERCENT FROM SOUTH TO
NORTH WEDNESDAY.

THE PROBLEM WITH THIS SYSTEM WILL BE WITH PRECIPITATION TYPES. THE
LATEST MODELS WOULD SUGGEST THE SURFACE LOW WILL TRACK RIGHT
ACROSS THE FORECAST AREA WHICH WOULD BRING IN SOME WARM AIR ALOFT
AND AT THE SURFACE. JUST HOW FAR NORTH THE WARM AIR WILL MAKE IT
WILL HAVE A BIG IMPACT ON THE SNOW AMOUNTS. CURRENTLY BRINGING IN
RAIN OR A RAIN/SNOW MIX TO THE I90 CORRIDOR FOR TUESDAY AND
TUESDAY NIGHT BEFORE THE LOW GOES BY AND MOST OF THE AREA GOES
OVER TO SNOW WEDNESDAY. THE PRECIITATION RATE IN THE POTENTIAL MIX
AREA COULD BE HIGH ENOUGH TO OVERCOME THE WARM AIR AND PRODUCE
MORE SNOW. THERE COULD ALSO BE A BRIEF PERIOD OF SOME FREEZING
RAIN AS THE WARM AIR ALOFT COMES IN...BUT DID NOT INCLUDE THIS AT
THIS TIME AS IT LOOKS TO BE VERY BRIEF AND CONFIDENCE ON WHERE IT
WOULD FALL IS NOT REAL HIGH AT THIS POINT. AMPLE GULF MOISTURE
WILL BE BROUGHT NORTH WITH THIS SYSTEM WITH PRECIPITABLE WATERS OF
0.75 TO 1 INCH POSSIBLE. HEAVY SNOW IN THE COLD AIR WILL BE A
CONCERN WITH THIS SYSTEM AND CURRENT INDICATIONS ARE THAT AMOUNTS
OF 6 TO 10 INCHES WILL BE POSSIBLE FOR AREAS ALONG AND NORTH OF
INTERSTATE 90. THE HIGHEST ACCUMULATIONS...WHICH COULD BE IN
EXCESS OF 10 INCHES...CURRENTLY LOOK TO BE POSSIBLE NORTH OF A
LAKE CITY TO BLACK RIVER FALLS LINE. WILL ISSUE A WINTER STORM
WATCH FOR THE POSSIBILITY OF THIS HEAVY SNOW FROM NOON TUESDAY
THROUGH WEDNESDAY. THE STARTING TIME OF THE WATCH MAY BE A LITTLE
EARLY BASED ON THE LATEST ECMWF...BUT RIGHT NOW THE TIMING AGREES
WITH WATCHES FROM SURROUNDING AREAS AND THIS CAN BE REFINED LATER
IF WARNINGS AND ADVISORIES ARE DEEMED NECESSARY.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY
317 PM CST SUN FEB 26 2012

ANOTHER LONG WAVE TROUGH IS EXPECTED TO CROSS THE REGION FRIDAY
WITH AN EMBEDDED SOUTHERN STREAM SHORT WAVE TROUGH IN THE BASE OF
THE LONG WAVE TROUGH. THE MODELS CURRENTLY SUGGEST THIS WOULD
RESULT IN TWO SURFACE LOWS...THE FIRST TRACKING ALONG THE CANADIAN
BORDER UNDERNEATH THE NORTHERN STREAM UPPER LEVEL LOW. THE SECOND
LOW WOULD BE COMING UP FROM THE SOUTHWEST THROUGH MISSOURI TOWARD
LAKE MICHIGAN. BOTH THE GFS AND ECMWF SHOW AMPLE MOISTURE WITH
THIS SYSTEM BUT THE QUESTION IS HOW FAR NORTH THIS PRECIPITATION
WILL GET. THE LATEST ECMWF HAS COME IN WITH A MUCH STRONGER AND
FARTHER NORTH SOLUTION BUT FOR NOW HAVE REMAINED WITH THE MODEL
CONSENSUS UNTIL A CLEAR TREND BECOMES EVIDENT.

&&

.AVIATION...THROUGH 18Z MONDAY
1154 AM CST SUN FEB 26 2012

STRONG SOUTHWEST TO WEST WINDS WILL PERSIST AT THE TAF SITES
THROUGH EARLY THIS EVENING. AT KRST...PLAN ON SUSTAINED WIND
SPEEDS OF 21 TO 26 KTS WITH GUSTS TO AROUND 43 KTS. AT KLSE...LOOK
FOR SUSTAINED WIND SPEEDS IN THE 16 TO 19 KT RANGE WITH GUSTS
TO AROUND 30 KTS. AN VFR/MVFR STRATOCUMULUS DECK WILL JUST GRAZE
THE TAF SITES THIS AFTERNOON PRODUCING SCT-BKN CLOUDS WITH BASES
IN THE 2-3.5 KFT RANGE. WIDESPREAD STRATUS IS EXPECTED TO PUSH
INTO THE TAF SITES THIS EVENING WITH CLOUD BASES IN THE 2 TO 3 KFT
RANGE. THE WINDS WILL GRADUALLY SUBSIDE BY MID EVENING AND VEER
NORTHWEST AS STRONG SURFACE LOW PRESSURE MOVES FROM CENTRAL
MINNESOTA INTO WESTERN UPPER MICHIGAN. LOOK FOR NORTHWEST WINDS OF
15 TO 20 KTS OVERNIGHT. PLAN ON MVFR CONDITIONS THROUGH MID MONDAY
MORNING AS STRATUS PERSISTS ACROSS THE AREA. HIGH PRESSURE IS
EXPECTED TO BUILD IN LATE MONDAY MORNING INTO MONDAY AFTERNOON
WITH SKIES CLEARING AND WINDS BECOMING LIGHT OUT OF THE NORTHWEST.
