AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
205 AM CST SAT DEC 3 2005

.SHORT TERM...THROUGH MONDAY NIGHT

FORECAST CONCERNS WERE PRIMARILY FOCUSED ON SNOWFALL TODAY INTO
TONIGHT.

SURFACE ANALYSIS HAD HIGH PRESSURE STRETCHING FROM MN AND WI INTO
THE OHIO VALLEY. LOW PRESSURE WAS SITUATED NEAR THE TX/OK
PANHANDLE...WITH A WARM FRONT EXTENDING EASTWARD INTO ARKANSAS. LIGHT
SNOW OCCURRING OVER THE FORECAST AREA GENERALLY FROM THE MISSISSIPPI
RIVER AND WESTWARD ASSOCIATED WITH MID LEVEL FRONTOGENESIS. WATER
VAPOR IMAGERY INDICATED MID LEVEL TROUGH ACROSS THE INTERMOUNTAIN
WEST...WITH SHORT WAVE ADVANCING INTO NORTHERN PLAINS AND ANOTHER
WAVE MOVING ACROSS NORTHERN NEVADA.

00Z 03DEC05 MODELS WERE IN FAIRLY GOOD AGREEMENT WITH SURFACE AND
UPPER LEVEL FEATURES THROUGH 60HRS. THEREFORE...FORECAST CONFIDENCE
WAS HIGH WITH DETAILS OF SNOW EVENT TODAY INTO TONIGHT. AFTER
60HRS...CONFIDENCE DECREASED SOMEWHAT AS GFS AND NAM HAD DIFFERENCES
WITH ANOTHER WEAK SURFACE WAVE TO MOVE THROUGH THE MIDWEST EARLY IN
THE WEEK. SINCE ECMWF HAS HAD CONTINUITY WITH A WEAK SYSTEM TO AFFECT
THE AREA IN THIS TIME FRAME...PREFER THE GFS.

TODAY...EASTWARD PROGRESS OF SNOW THIS MORNING SHOULD BE IMPEDED BY
DRIER AIR SITUATED OVER WI. THEREFORE...ACCUMULATIONS EXPECTED TO BE
MAINLY FROM THE MISSISSIPPI RIVER AND POINTS WESTWARD. DURING THE
AFTERNOON...ANOTHER ROUND OF MID LEVEL FRONTOGENESIS ANTICIPATED...
WITH BULK OF THE FORCING ACROSS THE SOUTHERN MOST PORTION OF THE
FORECAST AREA. NEGATIVE EPV NOTED AS WELL...WHICH SUGGESTS SOME
INSTABILITY IN THE FRONTOGENETIC AREA. IN ADDITION...DECENT
DENDRITIC CRYSTAL GROWTH SHOULD OCCUR BASED ON LARGE SNOW GROWTH
ZONE AS SHOWN IN BUFKIT AND JUXTAPOSITION OF MINUS 15C ISOTHERM IN
PROXIMITY TO VERTICAL MOTION FIELD.

IMPACT ON THE FORECAST WAS TO INCREASE SNOW AMOUNTS GENERALLY ACROSS
SOUTHERN MOST PARTS OF THE FORECAST AREA. NEAR ADVISORY CRITERIA
AMOUNTS EXPECTED THERE...WITH TOTALS OF 2 TO 4 INCHES ALONG AND SOUTH
OF A LINE FROM OELWEIN IOWA TO RICHLAND CENTER WI. GFS COBB OUTPUT
AND NCEP DAY ONE SNOW OUTLOOK AGREED WITH THIS THINKING.

TONIGHT...FORCING EXITS QUICKLY THIS EVENING BETWEEN 00Z-03Z
04DEC05. THUS...SNOW SHOULD TAPER OFF AND END...WHICH CURRENT DATA
BASE ALREADY REFLECTED VERY WELL.

.LONG TERM...TUESDAY THROUGH FRIDAY

MONDAY INTO TUESDAY...AS MENTIONED EARLIER...THE GFS AND ECMWF HAVE
SHOWN YET ANOTHER WEAK SURFACE WAVE SHOULD BRING ANOTHER LIGHT SNOW
EVENT. IN FACT...GFS HAS INDICATED A CONSISTENT Q-G CONVERGENCE
SIGNAL IN THE LAST COUPLE MODEL RUNS...WITH BULK OF FORCING ACROSS
THE SOUTHERN MOST PARTS OF THE FORECAST AREA. WE HAD ENOUGH
CONFIDENCE TO NUDGE SNOW PROBABILITIES UPWARD GENERALLY OVER ABOUT
THE SOUTH HALF OF THE FORECAST AREA.

WEDNESDAY THROUGH FRIDAY...THIS TIME FRAME APPEARS TO BE DOMINATED
BY A MASSIVE ARCTIC HIGH PRESSURE AS INDICATED BY ECMWF AND GFS.
BASED ON GFS MOS GUIDANCE...AS WELL AS GFS AND ECMWF 850MB
TEMPERATURES OF MINUS 16C-MINUS 18C...CURRENT DATA BASE READINGS MAY
NEED TO BE LOWERED...ESPECIALLY MINIMUM TEMPERATURES. NO CHANGES
WERE MADE...THUS ALLOWING DAY SHIFT TO FURTHER EVALUATE FULL SUITE OF
ENSEMBLE AND OPERATIONAL DATA.
