AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
251 PM CST MON FEB 2 2009

.SHORT TERM...THROUGH WEDNESDAY NIGHT

MAIN FORECAST CONCERN IS WITH ANY PRECIPITATION CHANCES TONIGHT AND
TEMPERATURES.

SURFACE ANALYSIS THIS AFTERNOON SHOWS A WEAK AREA OF LOW PRESSURE
OVER NORTHERN LAKE MICHIGAN WITH A TRAILING TROUGH OF LOW PRESSURE
BACK INTO NORTHERN MINNESOTA. HIGH PRESSURE WAS CENTERED OVER
SOUTHEAST SASKATCHEWAN WITH THE RIDGE AXIS SOUTH INTO SOUTH DAKOTA.

SATELLITE AND SURFACE OBSERVATIONS INDICATE THE ONLY CLOUDS ACROSS
THE REGION THIS AFTERNOON ARE ASSOCIATED WITH THE SURFACE TROUGH OF
LOW PRESSURE. MODELS HAVE BEEN TOO HIGH WITH MOISTURE ASSOCIATED
WITH THIS FEATURE AND THE ASSOCIATED SHORT WAVE TROUGH. THE SHORT
WAVE TROUGH WILL SLIDE WELL EAST OF THE AREA TONIGHT WITH THE VERY
WESTERN EDGE OF SOME WEAK QG CONVERGENCE BRUSHING THE AREA NORTHEAST
OF INTERSTATE 94. THE REMAINDER OF THE AREA IS UNDER THE INFLUENCE
OF THE SURFACE RIDGE AND IN QG SUBSIDENCE. THERE IS A SHORT PERIOD
OF ABOUT 5 MICROBARS/S OF UPGLIDE ON THE 270K ISENTROPIC SURFACE
FROM THE GFS DURING THE EVENING. THIS MAY BE ENOUGH TO PRODUCE A
SHORT PERIOD OF SATURATION AND ALLOW SOME LIGHT SNOW TO OCCUR...BUT
WOULD NOT BE SURPRISED IF THERE WAS NO SNOW OR JUST SOME FLURRIES.
THE RSM/GFS MEMBERS WERE THE ONLY ONES OF THE 02.15Z SREF THAT
PRODUCED ANY PRECIPITATION ACROSS THE AREA. WILL KEEP A SMALL
EVENING POP FOR AREAS NORTHEAST OF THE INTERSTATE 94 CORRIDOR AND
JUST GO WITH FLURRIES FOR THE OVERNIGHT.

UPPER AIR SOUNDINGS THIS MORNING FROM KABR AND KBIS SHOW A SHALLOW
ARCTIC AIR MASS IS IN PLACE UNDER THE SURFACE RIDGE. TEMPERATURES
THIS AFTERNOON ACROSS NORTH DAKOTA INTO WESTERN MINNESOTA REMAIN
BELOW ZERO. MOST OF THE 02.12Z MODEL SUITE IS NOT HANDLING THIS
SHALLOW COLD AIR EXCEPT FOR THE EASTARW AND NAM. THESE TWO MODELS
SEEM TO HAVE A GOOD HANDLE ON THE TEMPERATURES AND BASED ON THESE
DROPPED TEMPERATURES SIGNIFICANTLY FROM THE PREVIOUS DATA BASE.
CONTINUED THIS TREND THROUGH MUCH OF THE PERIOD WITH THE SURFACE
RIDGE NOT STARTING TO MOVE OFF UNTIL LATE WEDNESDAY NIGHT.

.LONG TERM...THURSDAY THROUGH MONDAY

DECENT AGREEMENT WITH THE LATEST SET OF MEDIUM RANGE MODELS OCCURS
THROUGH FRIDAY/FRIDAY NIGHT WITH PLENTY OF DIFFERENCES ARISING AFTER
THAT. PROBLEMS OCCUR ON THE HANDLING OF ENERGY COMING INTO THE
PACIFIC COAST AND WHETHER THIS WILL SLIDE EAST ALONG THE CANADIAN
BORDER LIKE THE GFS SUGGESTS OR HELP CARVE OUT A WESTERN CONUS
TROUGH PER THE ECMWF. THE 02.00Z GFS ENSEMBLES WHILE CLOSER TO THE
OPERATIONAL GFS SOLUTION DUE OFFER A BIT OF A COMPROMISE BETWEEN THE
TWO DETERMINISTIC MODELS WITH THE HPC GUIDANCE BLENDING IN EVEN MORE
ENSEMBLES NOT AVAILABLE TO THE FIELD OFFICES. HAVE THUS TRIED TO
STAY WITH CONTINUITY AND BLEND IN PREVIOUS DATASET WITH THE LATEST
HPC GUIDANCE. THIS LEADS TO A CONTINUATION OF THE SMALL POPS FOR
FRIDAY NIGHT AND SATURDAY FOR A MIX OF PRECIPITATION. THE GFS BUFKIT
SOUNDINGS STILL CONTINUE TO SUGGEST THIS COULD BE A FREEZING RAIN
EVENT BUT WITH THE ECMWF NOW SHOWING ALL THE PRECIPITATION FROM THIS
EVENT BEING NORTH OF THE AREA...WILL NOT INTRODUCE ANY FREEZING
TYPES UNTIL IT BECOMES CLEARER THAT THIS SYSTEM IS ACTUALLY GOING TO
PRODUCE PRECIPITATION OVER THE AREA. PER THE GFS ENSEMBLES WILL STAY
DRY UNTIL SUNDAY NIGHT AS THE NEXT SYSTEM STARTS TO COME OUT OF THE
SOUTHWEST. PROBLEMS WITH PRECIPITATION TYPES AGAIN AS WARM AIR
SHOULD SPREAD NORTH ONCE AGAIN.

&&

.AVIATION...

A COLD FRONT SLIPPED SOUTH ACROSS THE TAF SITES EARLY THIS
MORNING...WITH MID LEVEL DRYING POST THE FRONT LEADING TO SKC
CONDITIONS EARLY THIS AFTERNOON. LATEST SATELLITE IMAGERY HAS A
VFR/MVFR CLOUD DECK ACROSS NORTHERN SECTIONS OF MN/WI SINKING
SOUTH...WITH RH FIELDS WANTING TO BRING THESE CLOUDS ACROSS
KRST/KLSE BETWEEN 21-00Z. MODELS HAVEN/T HANDLED THE LOW LEVEL
MOISTURE WELL OVER THE PAST DAY OR TWO...SO WILL RELY MORE ON
SATELLITE TRENDS...WITH WOULD FAVOR BRINGING THIS CLOUD MASS DOWN
CLOSER TO 06Z. LOW LEVEL COLD AIR ADVECTION AND DECENT 700-500 MB
LAPSE RATES COULD SUPPORT SOME FLURRIES...BUT CONFIDENCE NOT HIGH
ENOUGH TO INCLUDE IN TAFS AT THIS TIME. FOR WINDS...THE SUN WILL
PROMOTE SOME MIXING THIS AFTERNOON...AND BLUSTERY NORTHWEST/NORTH
WINDS WILL CONTINUE INTO THE EVENING HOURS. PRESSURE GRADIENT STAYS
TIGHT INTO TUESDAY MORNING...WITH A SFC HIGH THEN BUILDING INTO THE
UPPER MISSISSIPPI RIVER VALLEY BY 06Z WED. WOULD NORMALLY EXPECT
DECREASING CLOUDS ON TUE AS A RESULT...HOWEVER...BUFKIT SOUNDINGS
INDICATE AN INVERSION AROUND 950 MB...WITH MOISTURE TRAPPED
UNDERNEATH THIS. MAY NEED THE HIGH AXIS TO MOVE ACROSS THE REGION
BEFORE THE SKIES GO SKC/SCT...WHICH WOULD NOT BE UNTIL WED MORNING.
DECENT AMOUNT OF SINKING AIR VIA SUBSIDENCE AND QG
DIVERGENCE...HOWEVER...COULD COUNTERACT THE LINGERING CLOUD
POTENTIAL. THIS WILL HAVE TO BE MONITORED FOR LATER TAF ISSUANCES.
