AREA FORECAST DISCUSSION...CORRECTED ISSUANCE TIME
NATIONAL WEATHER SERVICE LA CROSSE WI
316 AM CST WED JAN 23 2013

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT
316 AM CST WED JAN 23 2013

THERE ARE SEVERAL AREAS OF CONCERNS THROUGH THE SHORT TERM. FIRST
DEALS WITH LIGHT SNOW ACROSS SOUTHEAST MN...NORTHEAST IA AND FAR
SOUTHWEST WI TODAY. SECONDLY...WIND CHILLS THIS EVENING THROUGH
THURSDAY MORNING...AND FINALLY...LIKELIHOOD OF ACCUMULATING SNOW
THURSDAY NIGHT INTO FRIDAY.

WATER VAPOR RAP 500MB ANALYSIS SHOWS WELL ESTABLISHED SOUTHERN
EXTENSION OF THE POLAR VORTEX ACROSS THE AREA WITH NORTHWEST FLOW
BRINGING IN A SHORTWAVE TROUGH CURRENTLY EXTENDING FROM NORTHWEST WI
INTO NORTHWEST IA. 850-700MB WAA/ISENTROPIC LIFT PER THE RAP WAS
PRODUCING A BAND OF MOSTLY 7-10SM FLURRIES WITH POCKETS OF 4/5SM -SN
EXTENDING FROM SOUTHWEST MN INTO NORTH CENTRAL IA.

NAM SEEMS THE ODD MODEL OUT WITH THE SYSTEM COMING THROUGH THU N/FRI
WITH ITS FARTHER NORTH SOLUTION...AND PRETTY MUCH DISCOUNTED FOR
NOW. THE GFS/EC/GEM REMAIN IN PRETTY GOOD AGREEMENT AND THEREFORE
USING A CONSENSUS OF THESE MODELS.

FOR TODAY...MODELS CONTINUE TO SHOW GOOD 850-700MB WAA AND WEAK
270-280K WEAK ISENTROPIC UPGLIDE FROM SOUTHEAST MN INTO FAR
SOUTHWEST WI THROUGH THIS MORNING...SHIFTING SOUTHEAST OF THE AREA
BY AFTERNOON. BUMPED POPS INTO CATEGORICAL RANGE BASED ON THIS
FOCUSED FORCING SIGNAL SOUTH OF A LINE FROM DODGE CENTER AND
ROCHESTER MN THROUGH BOSCOBEL WI WHERE UP TO A HALF INCH OF SNOWFALL
IS POSSIBLE. FOR THIS AFTERNOON...COLD AIR ADVECTION BEHIND THE
SHORTWAVE TROUGH AND FAIRLY STEEP LOW LEVEL LAPSE RATES MAY LEAD TO
SOME FLURRY ACTIVITY ACROSS THE ENTIRE AREA. OTHERWISE...
TEMPERATURES WILL BE A BIT MILDER //RELATIVELY SPEAKING// TODAY WITH
HIGHS IN THE 10 TO 23 DEGREE RANGE. NORTHWEST WINDS WILL ALSO BE ON
THE INCREASE THIS AFTERNOON BEHIND THE WAVE.

BRISK NORTHWEST WINDS EXPECTED TO CONTINUE INTO THIS EVENING AS
TEMPERATURES START THE DOWNWARD TUMBLE INTO THE SINGLE DIGITS BELOW
ZERO RANGE ACROSS THE NORTHWEST PORTION OF THE FORECAST AREA. LOW
TEMPERATURES TONIGHT EXPECTED TO BOTTOM OUT IN THE MINUS 5 TO MINUS 10
DEGREE RANGE NORTHWEST OF A LINE FROM MEDFORD WI/BLACK RIVER
FALLS...THROUGH WINONA TO PRESTON MN AND OELWEIN IA WITH WIND CHILL
VALUES DIPPING INT THE 20-25 DEGREE RANGE. THEREFORE...WILL BE GOING
WITH A WIND CHILL ADVISORY FROM 8 PM THIS EVENING THROUGH 9 AM
THURSDAY FOR AREAS NORTHWEST OF THIS LINE.

ATTENTION THEN TURNS TO A FAIRLY VIGOROUS MID-LEVEL SHORTWAVE
TROUGH/SURFACE LOW DROPPING SOUTHEAST OUT OF ALBERTA CANADA INTO THE
DAKOTAS BY THURSDAY AFTERNOON...AND ACROSS CENTRAL WISCONSIN BY
FRIDAY MORNING. MODELS CONTINUE TO SHOWING FAIRLY STRONG N-S WING OF
850-700MB WAA/ISENTROPIC LIFT INTO THE AREA THURSDAY NIGHT AHEAD OF
THE WAVE INTO OUR AREA. THIS SIGNAL HAS BEEN INCREASING IN
CONSISTENCY FRO THE LIKELIHOOD OF SOME ACCUMULATING SNOW FOR THE
AREA. RIGHT NOW...IT APPEARS ANYWHERE FROM 1 TO 3 INCHES LOOKS
PRETTY LIKELY WITH THE HIGHER-END AMOUNTS ALONG AND NORTH OF THE
I-94 CORRIDOR. OTHERWISE...LOOKING FOR HIGHS ON THURSDAY IN THE
TEENS AND LOWS THURSDAY NIGHT IN THE SINGLE DIGITS TO TEENS ABOVE
ZERO.

SOME LINGERING DEFORMATION SNOW LOOKS LIKELY MAINLY THROUGH FRIDAY
MORNING AS THE LOW DIVES INTO LOWER MICHIGAN WITH PERHAPS AN
ADDITIONAL HALF TO ONE INCH POSSIBLE. SKIES CLEAR FRIDAY NIGHT WITH
LOWS DROPPING OFF INTO THE SINGLE DIGITS BELOW TO SINGLE DIGITS
ABOVE ZERO AS HIGH PRESSURE BUILDS IN FROM THE DAKOTAS.

.LONG TERM...SATURDAY THROUGH TUESDAY
316 AM CST WED JAN 23 2013

23.00Z GFS/ECMWF IN FAIRLY DECENT AGREEMENT THROUGH THE LONG TERM
PERIOD. HIGH PRESSURE HOLDS ACROSS THE AREA ON SATURDAY FOR MOSTLY
SUNNY SKIES WITH HIGHS EXPECTED TO TOP OFF IN THE TEENS. HIGH
PRESSURE MOVES OFF TO THE EAST SATURDAY NIGHT WITH WAA KICKING IN
AHEAD OF A MID LEVEL TROUGH EJECTING OUT OF THE INTERMOUNTAIN WEST.
THIS SPREADS CLOUD AND A SLIGHT CHANCE OF SNOW INTO THE AREA WEST OF
THE MISSISSIPPI RIVER. FOR SUNDAY THROUGH TUESDAY...LOW PRESSURE
GETS ORGANIZED ON THE LEESIDE OF THE CENTRAL ROCKIES/HIGH PLAINS.
THIS PUTS THE AREA IN BROAD AREA OF ISENTROPIC LIFT/WAA FOR A CHANCE
OF SNOW SUNDAY/SUNDAY NIGHT AND SNOW POSSIBLY MIXING WITH RAIN
MONDAY/TUESDAY DURING THE DAY AS TEMPERATURES WARM INTO THE
MIDDLE/UPPER 30S. WILL HAVE TO MONITOR THIS SYSTEM CLOSELY AS IT HAS
THE POTENTIAL OF BECOMING A FAIRLY STRONG SYSTEM WITH A GOOD AMOUNT
OF PRECIPITATION POSSIBLE.

&&

.AVIATION...
1115 PM CST TUE JAN 22 2013

CLOUDS WILL CONTINUE TO INCREASE AND LOWER OVERNIGHT...AHEAD OF
AN APPROACHING UPPER LEVEL SHORTWAVE TROUGH. EXPECT MVFR CIGS FOR
MOST OF WED MORNING. WHILE NOT OVERLY DYNAMIC...ENOUGH LIFT TO
PRODUCE AN AREA OF -SN THAT WILL IMPACT KRST. KLSE LOOKS TO BE ON
THE NORTHERN FRINGE. BUFKIT SOUNDINGS SUGGEST THE VERTICAL PROFILE
WOULD FAVOR DENDRITES...WHICH WOULD HELP LOWER VSBYS. LIGHT...FLUFFY
ACCUMS UP TO 1/2 INCH AT KRST ARE POSSIBLE. AN ASSOCIATED
SFC FRONT WILL SLIDE IN FOR MID/LATE MORNING...SWINGING WINDS TO THE
NORTHWEST. EXPECT SOME GUSTINESS POST THE FRONT...WHICH WOULD
CONTINUE INTO THE MID EVENING HOURS. SKIES SHOULD GRADUALLY CLEAR
WEST TO EAST WED EVENING.

A SFC HIGH WILL BUILD IN BY 15Z THU...WITH LIGHT WINDS AND VFR
CONDITIONS FOR THE BETTER PART OF THE DAY.
