AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
250 PM CST WED DEC 5 2007

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT

FORECAST CONCERNS FOCUS ON THE SYSTEM TO MOVE THROUGH ON THU/THU
NIGHT.

A 500 MB SHORTWAVE IS SLATED TO SLIDE EAST OUT OF THE
ROCKIES...SPINNING ACROSS THE UPPER MISSISSIPPI RIVER VALLEY FOR THU
AFTERNOON/EVENING. GOOD CONSISTENCY WITH THE MODELS...WITH THE
GFS/NAM/SREF ALL HAVING A SIMILAR PLACEMENT/TIMING ON THIS
SHORTWAVE. THE SHORTWAVE IS GETTING NUDGED ALONG BY A WEST-EAST
RUNNING 300 MB JET...WHOSE LEFT EXIT REGION WILL BE OVER THE AREA BY
00Z FRI. THE IMPLIED A-GEOSTROPHIC MOTIONS IN THIS AREA SHOULD
ENHANCE THE LIFT FROM THE SHORTWAVE. GOOD QG CONVERGENCE IN THE
300:700 MB LAYER ACROSS THE LOCAL AREA WITH THE SHORTWAVE...BUT THE
DEEPER AND STRONGER CONVERGENCE IS BROUGHT ACROSS CENTRAL IOWA.
PRETTY GOOD THERMODYNAMICS WITH THIS SYSTEM...WITH WARM AIR
ADVECTION THROUGH THE 925:850 LAYER...ALONG WITH ISENTROPIC UPGLIDE
ON THE 280:295 K SFCS. AGAIN THOUGH...THE MAIN FOCUS IS JUST
SOUTH...ACROSS IOWA. ALL IN ALL...SNOW LOOKS LIKE A SAFE BET FOR
THURSDAY AFT/THURSDAY EVENING...WITH THE MOST FAVORABLE TIME LOCALLY
BETWEEN 20Z-02Z. IT SHOULD BE A QUICK MOVING SYSTEM...WHICH WILL
HELP KEEP SNOW AMOUNTS DOWN SOMEWHAT...AND THIS IS THE BIGGEST
QUESTION...JUST HOW MUCH SNOW CAN BE EXPECTED.

FOR TOTALS...COBB OUTPUT PRETTY CONSISTENT WITH LAYING DOWN 2 TO 4
INCHES ACROSS THE AREA IN THAT MID AFTERNOON/EARLY EVENING TIME
FRAME ON THU. THIS LOOKS REASONABLE WITH THE FORCING AND SPEED OF
THE SYSTEM. THE HIGHER ACCUMULATIONS SHOULD BE THE SOUTH...WITH THE
BETTER OVERALL FORCING. WITH THIS IN MIND...WITH GO WITH A SNOW ADV
FOR 18-06Z FOR NORTHEAST IA/SOUTHWEST WI. IT PROBABLY WON/T START
ACROSS SW WI UNTIL AFTER 21Z...BUT THE 18Z-06Z TIME FRAME COVERS THE
AREA WELL. THIS ADV MAY NEED TO BE EXPANDED NORTH.

ONE LAST CAVEAT TO THIS SYSTEM...AS IT PASSES THE SATURATION
DECREASES IN THE MID LAYERS...LEAVING A MOIST LAYER BELOW 800 MB
FROM 06-12Z. THE MODELS HINT AT LINGERING SOME ISENTROPIC LIFT FOR A
FEW HOURS AFTER MIDNIGHT...WHICH COULD LEAD TO SOME FREEZING
DRIZZLE. NOT OVERLY ENTHUSED BY THESE CHANCES AT THE MOMENT...SO
WILL LEAVE OUT OF THE FORECAST FOR NOW. HOWEVER...IT WILL NEED TO
BE MONITORED.

THE NEXT SYSTEM OF NOTE IS SLATED TO MOVE IN SAT/SAT NIGHT. DEEP 500
MB TROUGH WILL HAVE WORKED ACROSS THE ROCKIES BY 00Z SUN...SPITTING
SOME SHORTWAVE ENERGY OUT OF THE TROUGH AND TOWARD THE REGION. GOOD
ISENTROPIC UPGLIDE OUT AHEAD OF THE SHORTWAVE...WITH THE MODELS
BREAKING OUT PCPN ACROSS THE PLAIN STATES/IA/MO BY 00Z SUN. THE NAM
IS THE SLOWER OF THE MODELS...WITH THE EC/GFS MORE
AGGRESSIVE...MOVING PCPN ACROSS THE FORECAST AREA BETWEEN 18-00Z. ON
THE WHOLE...THE EC IS THE MORE ROBUST OF THE MODELS...AND BELIEVE
ITS A BIT OVERDONE. WITH TRENDS MORE TOWARD THE GFS FOR THIS TIME.
MORE ON THIS IN THE EXTENDED PORTION OF THE FORECAST. THE SAT/SAT
NIGHT SYSTEM HAS THE POTENTIAL FOR A FEW MORE INCHES OF SNOW...BUT
FORECAST CONFIDENCE IS NOT HIGH AS TO WHERE/HOW MUCH AS OF NOW.

.LONG TERM...SUNDAY THROUGH WEDNESDAY

MODEL DIFFERENCES LOWERING THE CONFIDENCE IN THE EXTENDED PORTION OF
THE FORECAST...WITH ENSEMBLES ALSO SHOWING WIDE VARIANCES BETWEEN
THEIR MEMBERS. FIRST...FRONTAL BOUNDARY IS EXPECTED TO DEVELOP TO
THE SOUTHEAST OF THE UPPER MISSISSIPPI RIVER VALLEY BY SUNDAY...WITH
A LOW DEVELOPING AND MOVING UP THIS BOUNDARY. THE GFS/S POSITIONING
WOULD KEEP THE BULK OF THE PCPN WITH THIS SYSTEM FROM THE MID
MISSISSIPPI RIVER VALLEY INTO THE EASTERN GREAT LAKES. THE
EC...MEANWHILE...IS FARTHER NORTH...AND WOULD DROP SNOW OVER EASTERN
IOWA INTO CENTRAL WI. THIS IS A SHIFT NORTH FOR THE EC...COMPARED TO
ITS PREVIOUS RUNS...WHILE THE GFS HAS BEEN A BIT MORE CONSISTENT TO
THE SOUTH. WILL LEAN TOWARD THE GFS AS A RESULT. THEN...ANOTHER
SHORTWAVE TROUGH WILL LIFT OUT OF THE SOUTHERN PLAINS AND MOVE
TOWARD THE REGION. AGAIN...MODEL DIFFERENCES HERE...WITH THE EC
TAKING THIS SYSTEM ACROSS THE OH RIVER VALLEY...WHILE THE GFS IS
SLOWER AND WOULD BRING IT ACROSS THE LOCAL AREA. IN THIS CASE...THIS
IS A SHIFT NORTH FOR THE GFS COMPARED TO ITS PREVIOUS RUNS...AND
WILL TREND TOWARD THE EC IN THIS STEAD. OVERALL...THE FAIRLY ACTIVE
WINTER WEATHER COULD CONTINUE FOR THE END OF THE WEEKEND AND INTO
EARLY NEXT WEEK...BUT CONFIDENCE IS LOW IN THE
TRACK/TIMING/POSITIONING OF THESE NEXT COUPLE SYSTEMS.

&&

.AVIATION...

PERIOD FOR TAFS IS DOMINATED BY VFR CONDITIONS. HOWEVER...SHORTLY
AFTER THE END OF THE TAFS A 6HR IFR/LIFR PERIOD OF SN- PERIODIC SN+
WILL AFFECT THE SITES. THESE CONDITIONS WILL MOVE IN FROM THE WEST
AND BE LOCATED JUST WEST OF KRST BY DEC 6 18Z. THUS...THE MAIN IFR
OR BELOW PERIOD WITH ACCUMULATING SNOW WILL BE 18Z-00Z. THIS SNOW
WILL LIKELY BRING WIDESPREAD IFR SOUTH OF A KMSP-KGRB LINE TO
