AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
252 AM CST SUN DEC 14 2008

.SHORT TERM...TODAY THROUGH TUESDAY NIGHT

FORECAST FOCUS ON RAIN AND TEMPERATURE CONCERNS WITH THE STORM TODAY
AND TONIGHT...INCLUDING VERY COLD WIND CHILLS AND THE NEED FOR AN
ADVISORY.  ATTENTION THEN TURNS TO THE NEXT SYSTEM FOR THE LATTER
HALF OF TUESDAY.

08Z SURFACE ANALYSIS SHOWS THE CENTER OF THE LOW PRESSURE AREA OVER
EASTERN NEBRASKA...MAKING GOOD PROGRESS EAST/NORTHEAST THE LAST
SEVERAL HOURS. A WARM FRONT REACHED NORTHEAST FROM THE LOW ACROSS
SOUTHERN MN AND NORTHERN WI.  DEEP SOUTHERLY FLOW AHEAD OF THE SYSTEM
CONTINUES TO BRING WARM AND MOIST AIR INTO THE LOCAL AREA...WHICH IS
HELPING TO EXPAND CLOUDINESS. MEANWHILE TEMPERATURES PLUMMETING
QUICKLY BEHIND THE SYSTEM...WITH A BROAD AREA OF SNOW IN THE DEEPER
COLD AIR.

SYSTEM WILL TRACK NORTHEAST ACROSS SOUTHEAST MN BY MID-DAY...AND INTO
NORTHERN WI BY EVENING. THIS TRACK KEEPS THE AREA IN THE WARM SECTOR
THROUGH MUCH OF THE DAY...THUS THE PRECIP TYPE LOOKS TO REMAIN RAIN.
ISENTROPIC UPGLIDE SHOULD AID IN SATURATION...AND EXPECT AREAS OF
DRIZZLE AND/OR LIGHT RAIN TO BREAK OUT ACROSS THE AREA. MODELS HAVE
BEEN OVER-DOING THE LOW LEVEL MOISTURE THE LAST FEW RUNS...SO THIS
IS A CONCERN...BUT WITH THE MAIN FORCING NOW HERE...WILL NOT BACK
AWAY FROM THE GOING POPS/WEATHER AT THIS POINT. THE TRAILING COLD
FRONT LOOKS TO MOVE INTO THE WESTERN ZONE GROUPS AROUND NOON...AND
ACROSS THE REST OF THE FORECAST AREA BY EARLY EVENING. A WIND SHIFT
TO THE NORTHWEST WILL MARK THE START OF STRONG COLD ADVECTION. WITHIN
A FEW HOURS...READINGS SHOULD DROP SOME 20 DEGREES. POST FRONTAL
STRATUS AND DEEPENING COLD POOL SHOULD ALLOW SOME LIGHT SNOW OR
FLURRIES TO FALL...BUT THE DEEPEST MOISTURE WILL HAVE BEEN SHUNTED
NORTHEAST OUT OF THE AREA BY THEN. THUS...VERY LITTLE IF ANY
ACCUMULATION EXPECTED. HOWEVER...WITH THE MILD AND DAMP AIR IN
PLACE...WET SURFACES ARE EXPECTED TO QUICKLY FREEZE AS THE MERCURY
NOSE-DIVES. WINDS WILL BECOME QUITE GUSTY...WITH GUSTS UP AROUND
40 MPH. OVERNIGHT...THE COMBINATION OF WIND AND COLD WILL SEND WIND
CHILLS LOWER THAN -20...SO WILL GO AHEAD AND ISSUE A WIND CHILL
ADVISORY FOR MUCH OF THE FORECAST AREA...WHERE THE GREATEST THREAT
AND LONGEST TIME SCALE OF SUB -20 CHILLS EXISTS.

AS THE DRY INTRUSION MOVES IN SUNDAY NIGHT...HAVE BACKED DOWN ON
POPS AND CLOUD COVER. WITH THIS...VERY LITTLE IF ANY SNOW. BUT IT
WILL MOST CERTAINLY FEEL COLD...WITH WIND CHILLS FROM -20 TO -30.
NAM THE COLDEST WITH GUIDANCE TEMPERATURES...WITH OTHER MODELS A BIT
WARMER.  TRENDED CLOSER TO THE NAM GIVEN WHAT IS BEING SEEN ALREADY
ACROSS THE DAKOTAS THIS MORNING.

COLD ARCTIC HIGH SETTLES INTO THE NORTHERN PLAINS/UPPER MIDWEST
MONDAY THROUGH MONDAY NIGHT...WITH STRONG ARCTIC HIGH PRESSURE TAKING
UP RESIDENCE. NOT MUCH OF A TEMP RECOVERY MONDAY...WITH HIGHS RANGING
FROM THE SINGLE DIGITS TO MID TEENS. WITH SLACKENING WINDS AND
DECREASING CLOUD COVER...EXPECT LOWS TO BE QUITE CHILLY.  KNOCKED
THEM DOWN A CATEGORY OR TWO MOST PLACES.

MODELS ALL NOW IN PRETTY GOOD AGREEMENT IN BRINGING AN UPPER LEVEL
SHORT WAVE QUICKLY ACROSS THE PLAINS MONDAY NIGHT...AND ACROSS IA/IL
ON TUESDAY. AS IT DOES...A SUPPLY OF LIFT AND ELEVATED MOISTURE MOVES
OVER THE DEEP COLD DOME...GENERATING SEVERAL HOURS OF HIGH-RATIO
LIGHT FLUFFY SNOW. COBB DATA SUGGESTING RATIOS OF 15:1 TO 18:1...WITH
MODEL QPF FROM A TENTH TO A QUARTER INCH. WITH THESE PARAMETERS...
SNOWFALL FROM 2 TO 4 INCHES LOOK TO BE A GOOD BET TUESDAY AND TUESDAY
NIGHT.  WILL HAVE TO WATCH AS THE DETAILS BECOME MORE CLEAR ON
THIS...AS IT COULD NECESSITATE AN ADVISORY.

.LONG TERM...WEDNESDAY THROUGH SATURDAY

ACTIVE PATTERN LOOKS TO CONTINUE THROUGH THE MEDIUM RANGE PERIOD.
POLAR VORTEX OVER SOUTHERN CANADA CONTINUES TO SPIN WEAK DISTURBANCES
DOWN INTO THE UPPER MIDWEST FOR THE REMAINDER OF THE WEEK. ONCE SUCH
WAVE WILL MOVE THROUGH THE REGION THURSDAY/THURSDAY NIGHT. MODELS
HAVE BEEN TRENDING STRONGER WITH THE WAVE AND ASSOCIATED SURFACE
REFLECTION...AND THIS ONE LOOKS TO HAVE THE POTENTIAL FOR SOME
LIGHT ACCUMULATIONS OF SNOW FOR THE REGION. ANOTHER ONE LOOKS TO
MOVE THROUGH LATE FRIDAY...SO WILL HAVE TO MONITOR THAT POSSIBILITY
DURING LATER SHIFTS.

.AVIATION...

LATEST FOG/STRATUS SATELLITE IMAGERY SHOWS AN INCREASE IN MID LEVEL
CLOUDS ACROSS THE LOW AREA...ALTHOUGH LOW STRATUS WAS
DEVELOPING/EXPANDING OVER NEB. RH FIELDS SHOW AN INCREASE IN THE LOW
SATURATION EARLY THIS MORNING...WHICH WOULD RESULT IN MVFR/IFR
CEILINGS. IN ADDITION...BR WOULD ALSO RESULT AS THE SOUTHERLY WINDS
OVER THE SNOW PACK ADDS MORE MOISTURE TO THE ATMOSPHERE.
PRECIPITATION ASSOCIATED WITH AN APPROACHING STORM SYSTEM WAS TO THE
EAST...WHILE SNOW WAS FALLING OVER CENTRAL/NORTHERN MN. AT
KRST/KLSE...LIGHT PCPN LOOKS TO BECOME MORE LIKELY BY LATE
MORNING...CONTINUING INTO EARLY EVENING. AS THE FRONT PASSES BETWEEN
21-00Z...DRY AIR AND SUBSIDENCE WILL DRAW TO AN END THIS
PCPN...ALTHOUGH THE LOW CEILING SHOULD HANG AROUND THROUGH MUCH OF
MONDAY. VSBYS SHOULD ALSO RAPIDLY IMPROVE BEHIND THE FRONT...WITH
THE WINDS BECOMING STRONG AND GUSTY FROM WEST/NORTHWEST.
