AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
250 AM CST MON JAN 12 2009
.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT
FORECAST FOCUS IS ON THE PARADE OF SHORTWAVE TROUGHS TO IMPACT THE
REGION OVER THE NEXT FEW DAYS...HEADLINES TODAY...WHAT TYPE AND
WHERE.
BITS OF UPPER LEVEL ENERGY WILL SPIN ACROSS THE REGION TODAY...BUT
THE MAIN 500 MB SHORTWAVE TROUGH WAS CURRENTLY TRACKING ACROSS THE
NORTHERN PLAINS...AND WILL SPIN ACROSS IA BY THIS EVENING. SFC LOW
ASSOCIATED WITH THE UPPER LEVEL FEATURE IS NEARLY STACKED WITH
IT...LEADING IT JUST A BIT AS IT MOVES INTO IA...AND THEN TAKES A
TURN EAST/NORTHEAST TONIGHT. GOOD QG CONVERGENCE BETWEEN
15-00Z...ESPECIALLY IN THE 500-850 MB LAYER. SOME ISENTROPIC UPGLIDE
ALONG THE 280-295 K LAYERS AHEAD OF THE TROUGH...ALONG WITH SOME LOW
LEVEL WARMING IN THE 925-850 MB LAYER. SATURATION INCREASES QUICKLY
AS THE SHORTWAVE APPROACHES...WITH A WEST-EAST RUNNING TIME/HEIGHT
X-SECTION BRINGING RELATIVELY DEEP MOISTURE TO LOCATIONS WEST OF THE
MISSISSIPPI RIVER BY 18Z...AND THEN EAST OF THERE BETWEEN 18-00Z.
SO...THE SATURATION WILL BE THERE FOR THE SHORTWAVE TROUGH AND LOW
LEVEL THERMODYNAMICS TO TAP INTO...RESULTING IN AREAS OF SNOW. TRACK
OF THE SYSTEM WOULD LIKELY PUT THE FORECAST AREA IN THE HEART OF THE
BETTER SNOW CHANCES/AMOUNTS...WITH LESS TO THE NORTH. COBB OUTPUT
HAS HAD SOME VARIANCE OVER ITS PAST FEW RUNS...BUT STILL HAS
BROUGHT A CONSISTENT 2 TO 4 INCHES. THIS CONTINUES TO LOOK
REASONABLE. AS THE SFC LOW MOVES OVER NORTHEAST ILL THIS EVENING...A
TIGHTENING PRESSURE GRADIENT WILL RESULT IN INCREASING WINDS FROM
WEST TO EAST. THIS SHOULD START BY THE AFTERNOON...BUT THE PERIODS
WITH THE STRONGEST WINDS LOOK TO BE THIS EVENING. BUFKIT SOUNDINGS
SUGGEST THE POTENTIAL TO MIX 30-35 KT WINDS TO THE SFC THIS
EVENING...WITH WINDS NEARLY UNI-DIRECTIONAL FROM THE SFC TO 700 MB.
WOULD EXPECT 20 TO 25 MPH WINDS WITH GUSTS 30 TO 35 WEST OF THE
MISSISSIPPI RIVER...OVER THE WIND PRONE AREAS OF SOUTHEAST
MN/NORTHEAST IA. THE WINDIEST CONDITIONS WILL LIKELY LIE JUST
WEST/SOUTH OF THE FORECAST AREA. STILL...ENOUGH TO LIFT AND BLOW THE
2 TO 4 INCHES OF POWDERY FLUFF EXPECTED TODAY...IN ADDITION TO THE
RECENT LIGHT SNOW FROM RECENT DAYS. OBVIOUSLY...THIS WILL IMPACT THE
WIND PRONE/OPEN/UNSHELTERED AREAS THE MOST...AND VISIBILITIES FROM
BLOWING SNOW BELOW 1 MILE...TO 1/2 MILE...LOOK LIKELY AT TIMES.
WHETHER OR NOT THEY FALL TO 1/4 MILE BLIZZARD CRITERIA IS NOT
CERTAIN THOUGH...AND CONFIDENCE IS NOT HIGH THAT THIS WILL OCCUR FOR
A PROLONGED PERIOD.
TAKING ALL THIS INTO CONSIDERATION...WILL GO WITH A WINTER STORM
WARNING TO ACCOUNT FOR THE COMBINATION OF SNOW AND BLOWING/DRIFTING
SNOW TO THE FAR WEST/SOUTHWEST...REPLACING THE BLIZZARD WARNING AND
ADDING IN BORDER COUNTIES. AGAIN...CONFIDENCE NOT HIGH ENOUGH THAT
BLIZZARD CONDITIONS WILL BE MET FOR A PROLONGED PERIOD...ALTHOUGH
PERIODS WITH WHITE-OUT CONDITIONS ARE LIKELY. FOR THE REST OF THE
FORECAST AREA...EXCEPT NORTH CENTRAL WI...WILL GO WITH A WINTER
WEATHER ADV FOR THE SNOW AND BLOWING/DRIFTING SNOW.
NEXT CONCERN IS THAT AS THE SYSTEM EXITS...A CONSIDERABLE AMOUNT OF
COLD AIR WILL FLOW SOUTH BEHIND IT...WITH A SFC HIGH MOVING
IN...ALBEIT TEMPORARILY...WED AFTERNOON. 925 MB TEMPS ARE PROGGED TO
FALL FROM AROUND -10 C AT 00Z TUE...TO -22 C BY 12Z TUES. THE
WEST-EAST X-SECTION SHOWS A RAPID DECREASE IN THE SATURATION...AND
EXPECTING CLEARING SKIES FROM WEST TO EAST OVERNIGHT AS A RESULT.
LOWS OF 5 TO 10 BELOW SHOULD OCCUR...SLIGHTLY COLDER FARTHER NORTH.
COUPLE THESE TEMPS WITH THE BLUSTERY WINDS...AND WIND CHILLS OF 25
TO 35 BELOW ZERO SHOULD BE COMMON FROM 06Z TONIGHT TO 18Z WED.
SO...WILL ISSUE A WIND CHILL ADVISORY FOR THIS PERIOD...BASICALLY
PICKING UP WHERE THE WINTER WEATHER WARNINGS/ADVISORIES END.
TUES NIGHT/WED LOOKS LIKE A NEAR CARBON COPY OF TODAY...AS BOTH THE
12.00Z GFS AND NAM SLIDE A 500 MB SHORTWAVE SOUTHEAST AS THE
NORTHERN PLAINS AND OVER THE UPPER MISSISSIPPI RIVER VALLEY TUES
NIGHT. AT THE SFC...A LOW MOVES OVER IA BY 12Z...THE TAKES AN
EASTWARD TRACK TOWARD THE NEW ENGLAND STATES. AGAIN...NEARLY
IDENTICAL TO THE EXPECTED MOVEMENT OF THE SYSTEM FOR TODAY. PLENTY
OF LOW LEVEL WARM AIR ADVECTION AND ISENTROPIC UPGLIDE TO TAP INTO
FOR PCPN CHANCES...WITH A BIT MORE LOW LEVEL 2-D FRONTOGENETIC
FORCING CURRENTLY INDICATED COMPARED TO TODAY/S SYSTEM. COBB OUTPUT
IS EERILY SIMILAR ALSO...WITH 00Z DATA DROPPING NEARLY THE SAME
TOTALS FOR SNOW TUES NIGHT/WED AS THEY DO FOR TODAY...RIGHT AROUND 4
INCHES AT RST AND LSE. RATIOS ARE HIGHER...20/25:1...OPPOSED TO THE
15:1 FOR TODAY. WINDS WILL ALSO BE FACTOR ON THE BACKSIDE OF THIS
CLIPPER-TYPE SHORTWAVE...PICKING UP BY LATE MORNING...AND CONTINUING
INTO WED EVENING. BUFKIT SOUNDINGS SHOW A SIMILAR POTENTIAL FOR
MIXING DOWN 30-35 KT WINDS. IF THE MODELS CONTINUE MIRRORING THIS
SYSTEM WITH TODAY/S...TODAY AND TONIGHT/S OUTCOME SHOULD BE
REFLECTED FOR TUES NIGHT/WED. HEADLINES MIGHT BE
NEEDED...AGAIN...MORE FOR THE COMBINATION OF SNOW/BLOWING SNOW
RATHER THAN SNOW ITSELF. ALSO...WIND CHILL ADVISORIES...POSSIBLY
WARNINGS...WOULD BE NEEDED WED NIGHT THROUGH THU MORNING.
.LONG TERM...THURSDAY THROUGH SUNDAY
ARCTIC HIGH STILL SLATED TO DROP ACROSS THE UPPER MISSISSIPPI RIVER
VALLEY ON THU...BRINGING A RE-ENFORCING SHOT OF COLD AIR...ALBEIT
WITH SOME SUNSHINE. THEN...THE CONVEYOR BELT OF 500 MB SHORTWAVE
TROUGHS CONTINUES...WITH BOTH THE GFS AND ECMWF DROPPING A SHORTWAVE
ACROSS THE REGION ON SAT. THE EC IS STRONGER AND A TAD MORE
EAST...LEADING TO ITS QPF MORE ACROSS THE EASTERN GREAT LAKES. THE
WEAKER GFS IS MORE WEST...WHICH WOULD RESULT IN SOME BETTER SNOW
CHANCES LOCALLY. TIMING IS COMPARABLE. OF MORE SIGNIFICANCE IS
FRIDAY...AS THE GFS DROPS A VORT MAX SOUTHEAST INTO THE
REGION...WHILE THE EC HAS A MUCH WEAKER...BROADER TROUGH. THE GFS
PAINTS MORE QPF AS A RESULT...WHILE THE EC IS RELATIVELY DRY. A
MAJORITY OF THE ENSEMBLE MEMBERS FAVOR SOME LIGHT QPF IN THIS TIME
FRAME. NOT A WHOLE LOT OF CONSISTENCY WITH THIS POTENTIAL SHORTWAVE
THOUGH...WHILE BOTH MODELS HAVE HELD ONTO THE SFC HIGH. ON GOING
FORECAST HAS BEEN DRY...AND WITH CONFIDENCE MORE IN THE HIGH
PRESSURE THAN IN THE UPPER LEVEL FEATURE...WILL KEEP THE FORECAST
DRY FOR FRI FOR NOW.
&&
.AVIATION...
WINTER STORM TODAY/TONIGHT TO BRING SIGNIFICANT IMPACTS TO AVIATION
ESPECIALLY KRST WHERE COMBINATION OF 2-4 INCHES OF SNOW AND STRONG
WINDS WILL LEAD TO SIGNIFICANT VSBY REDUCTIONS AND BLOWING SNOW.
SNOW WILL SPREAD INTO KRST APPROX 15Z AND INTO KLSE TOWARD 18Z.
SHOULD SEE CONDS RAPIDLY MOVE TO IFR IN FALLING SNOW...POTENTIALLY
AS LOW AS A HALF MILE AT TIMES. WINDS WILL LIKELY REMAIN BEHAVED
UNTIL 13.00Z AT KRST AND 13.02Z AT KLSE WHEN SHARP INCREASE IN
SPEEDS WILL OCCUR OUT OF THE NORTH/NORTHWEST. DESPITE SNOW QUICKLY
COMING TO AN END IN THIS PERIOD...CONDITIONS VIA BLOWING SNOW WILL
LIKELY CONTINUE TO CAUSE RESTRICTED VSBYS AND SIGNIFICANT DRIFTING
OVER RUNWAYS/TAXIWAYS...AGAIN ESPECIALLY AT KRST WHICH IS EXPOSED TO
STRONGER WINDS VS. KLSE. LOW CLOUDS/IFR CIGS WILL ERODE THROUGH THE
OVERNIGHT BUT STILL EXPECT TO SEE VSBY RESTRICTIONS AT KRST MUCH OF
THE NIGHT IN BLSN. AT KLSE...SHOULD SEE VSBYS LESS AFFECTED...BUT
AIRPORT GROUNDS WILL LIKELY SEE DRIFTING WHICH WILL HAMPER
MAINTENANCE OF PAVED SURFACES. BITTERLY COLD WIND CHILLS AFTER 06Z
AS WELL AT BOTH SITES...BETWEEN 20 AND 35 BELOW ZERO.
