AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
255 PM CST MON DEC 7 2009

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT

FORECAST FOCUS SQUARELY ON THE VERY DANGEROUS...HIGH IMPACT WINTER
STORM TO MOVE ACROSS THE AREA TUESDAY-WEDNESDAY.

MODEL CONSISTENCY BOTH BETWEEN AND WITHIN THEMSELVES CONTINUES WITH
THE 12Z MODELS SUITES...ALL DEPICTING A WINTER STORM MOVING OUT OF
THE PLAINS...STRENGTHENING AS IT MOVES INTO THE EASTERN GREAT LAKES
WED. CONFIDENCE IS VERY HIGH IN A SIGNIFICANT WINTER STORM TO IMPACT
THE REGION...WITH CONSIDERABLE SNOWFALL AND STRONG WINDS. BLIZZARD
TO NEAR-BLIZZARD CONDITIONS ALSO LOOK PROBABLE IN THE MORE OPEN AND
WIND PRONE AREAS.

UPPER LEVEL TROUGH WILL DRIVE ACROSS THE ROCKIES TONIGHT...PUSHING
THROUGH THE SOUTHERN PLAINS AND THEN INTO THE EASTERN GREAT LAKES BY
12Z WED. THE SYSTEM GETS A GOOD SHOVE EAST/NORTHEAST BY A 120+ KT
300 MB JET...WHICH WILL LEND ADDITIONAL LIFT IN ITS LEFT EXIT REGION
FOR THE AREA TUESDAY NIGHT. AT THE SFC...ALL THE MODELS BRING A LOW
ACROSS THE SOUTHERN TIP OF LAKE MICHIGAN BY 12Z WED...WITH ONLY
MINOR DIFFERENCES IN STRENGTH AND POSITIONING. THE LOW LEVEL WARM
ADVECTION AND 280-295 K ISENTROPIC UPGLIDE IS STRONGEST AS THE HEART
OF THE STORM APPROACHES...IN THE 18Z TUE-06Z WED TIME FRAME. MOST OF
THE SNOW ON TUES/TUES NIGHT WILL DEVELOP AS A RESULT OF THIS
FORCING. STRONG QG CONVERGENCE THROUGH THE LEVELS MOVES IN BY 06Z
WED...EXITING NORTHEAST AFTER 12Z WED. SOME 2-D FRONTOGENETIC
FORCING INDICATED ACROSS THE FORECAST AREA VIA A NORTHWEST-SOUTHEAST
RUNNING X-SECTION. NOT OVERLY STRONG...ALTHOUGH THERE ARE SOME HINTS
THAT THERE COULD BE AT LEAST ONE DECENT SNOWBAND DEVELOPING WITHIN
THE BROAD AREA OF SNOW POST THE STORM CENTER FOR LATE WED MORNING.
LITTLE IF ANY -EPV INDICATED...NOR ANY INSTABILITY LOOKING AT BUFKIT
SOUNDINGS...SO DON/T BELIEVE THERE WILL BE MUCH/IF ANY CONVECTIVE
SNOW THREAT. THERMODYNAMIC FORCED SNOW SHOULD BE MOVING INTO
NORTHEAST IA/SOUTHEAST MN/SOUTHWEST WI IN THE MORNING...ADVANCING
NORTHEAST ACROSS THE REST OF THE AREA BY THE AFTERNOON. SNOW WILL
INCREASE IN INTENSITY TUE NIGHT AS THE HEART OF THE SYSTEM
APPROACHES...WITH SNOW STARTING TO TAPPER OFF WED AFTERNOON/EVENING
AS IT EXITS NORTHEAST.

AS MENTIONED...THE IMPACTS OR THIS WINTER STORM WILL BE APPRECIABLE
SNOWFALL AND WINDS. LOOKING FIRST AT AMOUNTS...BUFKIT SOUNDINGS AND
TIME/HEIGHT X-SECTIONS INDICATE A FAIRLY AVERAGE DENDRITIC ZONE
GROWTH REGION THROUGH THE LENGTH OF THE EVENT. FRONTOGENETIC FORCING
DOES NOT APPEAR OVERLY STRONG...NOR DOES THERE SEEM TO BE MUCH OF A
THREAT FOR CONVECTIVE SNOWS. SO...FEEL THE CHANCE FOR BANDED SNOWS
CAPABLE OF PRODUCING 1 TO 2 INCH PER HOUR SNOWFALL RATES WILL BE
SMALL. HOWEVER...AS THE STRONGER FORCING MOVES IN TUESDAY
NIGHT...THE 07.09Z SREF GUIDANCE DOES HINT AT THE POTENTIAL FOR
HEAVIER SNOWFALL RATES...SO CAN/T DISCARD THE POSSIBILITY QUITE YET.
OVERALL THOUGH...FEEL ACCUMULATIONS WITH THIS STORM WILL BE THE
RESULT OF A LONG...DRAWN OUT EVENT...WITH GENERALLY AROUND 1/2 INCH
OF ACCUMULATION PER HOUR. COBB OUTPUT CONTINUES TO POINT TO 8 TO 12
INCHES FOR THE FORECAST AREA...AS IT HAS FOR ITS PAST MANY RUNS VIA
THE GFS AND NAM. THIS CONTINUES TO LOOK VERY REASONABLE. THE HIGHER
AMOUNTS LOCALLY SHOULD BE ACROSS NORTHEAST IA AND SOUTHWEST WI.

NEXT...AND POSSIBLY THE BIGGEST THREAT FROM THIS STORM...WILL BE
THE IMPACT FROM THE WINDS. THE PRESSURE GRADIENT WILL TIGHTEN
CONSIDERABLY AS THE STORM STRENGTHENS AND MOVES INTO THE REGION.
WINDS WILL BE ON THE INCREASE OVERNIGHT TUESDAY...BECOMING RATHER
STRONG AND GUSTY BY 12Z WED //20 TO 30 MPH...GUSTS TO 40//...AND
THEN CONTINUING THROUGH MOST OF THE DAY...WEAKENING LATER WED AS THE
STORM DEPARTS. CONSIDERABLE BLOWING AND DRIFTING WILL
RESULT...ESPECIALLY IN THE OPEN AND UNSHELTERED AREAS OF SOUTHEAST
MN AND NORTHEAST IA...ALONG WITH AREA RIDGE-TOPS. WHITE-OUT
CONDITIONS ARE A DISTINCT POSSIBILITY. THE STRONGEST WINDS WILL
LIKELY MOVE IN JUST AFTER THE BULK OF THE SNOW HAS FALLEN...BUT WILL
EASY KICK UP THE FRESHLY FALLEN SNOW.

THE MAIN QUESTION TO ANSWER NEXT IS WHETHER A WINTER STORM OR
BLIZZARD WARNING WILL BE MORE APPROPRIATE. WITH THE STRONGEST WINDS
DISPLACED IN TIME FROM THE ONSET OF THE SNOW AND BULK OF THE
ACCUMULATIONS BY ABOUT 12 HOURS...A CONCERN IS ISSUING A BLIZZARD
WARNING FOR THE MORE LIKELY LOCATIONS WEST OF THE MISSISSIPPI RIVER
STARTING TUE AFTERNOON...BUT NOT APPROACHING BLIZZARD CRITERIA UNTIL
AFTER 06Z WED. ACCUMULATING SNOWS WILL BE REALIZED TUE
AFTERNOON...BUT THE BLIZZARD POTENTIAL WON/T BE RAISED UNTIL THE
EARLY MORNING HOURS OF WED. FEELING RIGHT NOW IS TO CONTINUE TO
HIGHLIGHT THE HIGHEST IMPACT OF THE STORM...WHICH IS THE
POTENTIAL...LIKELIHOOD OF BLIZZARD CONDITIONS. SO...WILL ISSUE A
BLIZZARD WARNING FOR THE PORTIONS OF THE SOUTHEAST MN/NORTHEAST IA
UNDER THE BLIZZARD WATCH...AND GO WITH A WINTER STORM WARNING FOR
THE REST OF THE FORECAST. IT SHOULD BE EMPHASIZED THOUGH THAT FOR
THE BLIZZARD WARNING...BLIZZARD CONDITIONS ARE NOT EXPECTED FOR TUES
AFTERNOON/EVENING...RATHER THOSE WILL DEVELOP OVERNIGHT TUES AS THE
STRONG WINDS MOVE IN.

AGAIN...THIS IS A SIGNIFICANT WINTER STORM THAT WILL HAVE A HIGH
IMPACT ON THE REGION...ESPECIALLY DURING THE MORNING COMMUTE ON WED.
WHITE-OUT OR NEAR WHITE-OUT CONDITIONS ARE VERY POSSIBLE...AND ROADS
WILL BECOME VERY TREACHEROUS OR IMPASSABLE. THERE COULD BE SOME
INTERSTATE CLOSURES ON WED.

LOOKING INTO THU...VERY COLD AIR WILL FLOW INTO THE REGION...WITH
TEMPERATURES ALREADY FALLING THROUGH THE DAY ON WED. MORNING LOWS
THU WILL BE NEAR ZERO.

.LONG TERM...FRIDAY THROUGH MONDAY

OVERALL TRENDS VIA THE EXTENDED MODELS IS TO CONTINUE THE COLD POST
THE WINTER STORM. SINGLE DIGIT LOWS...ABOVE AND BELOW ZERO...ARE
LIKELY THROUGH THE UPCOMING WEEKEND. THE UPPER LEVEL FLOW IS
GENERALLY ZONAL TO SOME SLIGHT RIDGING...BUT SOME DIFFERENCES WITH
HOW THE MODELS WANT TO USHER WEAK SHORTWAVES THROUGH THE FLOW. THE
GFS/ECMWF/GEM WANT TO BRING ONE SHORTWAVE NORTHEAST OUT OF THE MO
RIVER VALLEY...INTO THE EASTERN GREAT LAKES THIS WEEKEND. SOME
TIMING AND POSITIONING DIFFERENCES...ALTHOUGH ALL THE MODELS FAVOR
PCPN CHANCES MORE TO THE SOUTH OF THE LOCAL AREA. CONFIDENCE ISN/T
HIGH WITH THIS FEATURE...AND WILL LIKELY LEAN TOWARD HPC GUIDANCE
FOR SNOW CHANCES.

&&

.AVIATION...TONIGHT THROUGH WEDNESDAY

PRIMARY CONCERN WAS ASSOCIATED WITH MAJOR WINTER STORM TO IMPACT THE
AREA TUESDAY INTO WEDNESDAY. WE CONTINUE TO ADVISE AIRPORT
MANAGERS...DISPATCHERS AND PILOTS TO KEEP ABREAST OF THE LATEST
FORECASTS DUE TO EXPECTED SIGNIFICANT IMPACTS ON SUCH OPERATIONS AS
SNOW REMOVAL...DEICING AIRCRAFT AND INSTRUMENT APPROACHES.

BASED ON EXCELLENT AGREEMENT WITHIN THE VARIOUS FORECAST DATA
SETS...CONFIDENCE REMAINS HIGH THAT A MAJOR WINTER STORM WITH HEAVY
SNOW...STRONG WINDS AND CONSIDERABLE BLOWING AND DRIFTING SNOW WILL
HAVE A MAJOR IMPACT ON AIRPORTS AREAWIDE.

IFR CONDITIONS IN SNOW EXPECTED TO ONSET AT THE TAF SITES TUESDAY
MORNING BETWEEN 08.12Z-08.18Z...WITH SNOW INCREASING IN INTENSITY
TUESDAY NIGHT...BEFORE TAPERING OFF LATER WEDNESDAY. IN
ADDITION...WINDS BECOME NORTHERLY AND INCREASE SIGNIFICANTLY LATE
TUESDAY NIGHT...LASTING THROUGH WEDNESDAY EVENING.

THERE WILL CERTAINLY BE A POTENTIAL FOR PEAK WIND GUSTS OF 30-40
KTS...ESPECIALLY AT THE WIND PRONE AIRPORTS OF SOUTHEAST MN AND
NORTHEAST IOWA...INCLUDING KRST. AS A RESULT...CONSIDERABLE BLOWING
AND DRIFTING SNOW IS EXPECTED TO CAUSE PROBLEMS FOR SNOW REMOVAL ON
AIRPORT RUNWAYS...TAXIWAYS AND RAMPS.
