AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
318 AM CST SUN NOV 30 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 318 AM CST SUN NOV 30 2014

CURRENTLY AS OF 09Z...WATER VAPOR LOOP AND RAP 500MB HEIGHT
ANALYSIS SHOWED TROUGHING FROM CENTRAL CANADA INTO THE NORTHERN
INTERMOUNTAIN WEST...AND WEST-SOUTHWEST FLOW FROM THE PLAINS INTO
NEW ENGLAND. ATMOSPHERE IN GENERAL ACROSS THE PLAINS INTO THE
FORECAST AREA IS QUITE DRY WITH PRECIPITABLE WATER VALUES LESS
THAN 1/2 INCH. IN FACT...UNDER THE UPPER TROUGH THEY ARE LESS THAN
1/10 OF AN INCH. ACCOMPANYING THE DRIER AIR HAS BEEN A VERY
IMPRESSIVE SURGE OF ARCTIC AIR. TEMPERATURES ACROSS THE DAKOTAS
INTO WESTERN MN HAVE DROPPED INTO THE SINGLE DIGITS ABOVE AND
BELOW ZERO...WITH TEENS TO 20 BELOW ZERO IN MONTANA WHERE HIGH
PRESSURE WAS LOCATED. THE ARCTIC FRONT HAS PASSED THROUGH THE
FORECAST AREA AND NOW SITUATED FROM GRB TO DVN AND KANSAS CITY. A
BAND OF LOW STRATUS AND GUSTY NORTHWEST WINDS HAVE FOLLOWED IN THE
WAKE OF THIS FRONT. THAT STRATUS HAS BEEN A FUNCTION OF TRAPPED
MOISTURE ALONG THE COLD FRONTAL INVERSION...REPRESENTED VERY WELL
ON THE 00Z MPX SOUNDING WHERE THE 850MB TEMP WAS 13C AND 925MB
TEMP WAS -2C. CLOUDS CLEAR OUT MORESO OVER MONTANA AND NORTH
DAKOTA WHERE THE INVERSION GOES AWAY...NOTED BY 850MB TEMPS -20C
AND BELOW.

WITH THE UPPER TROUGH OVER THE NORTHERN INTERMOUNTAIN WEST PROGGED
TO SLIDE ACROSS THE NORTHERN PLAINS AND EVENTUALLY SITTING OVER THE
FORECAST AREA BY 12Z MONDAY...EXPECTING TO SEE THE ARCTIC AIR OVER
THE NORTHERN PLAINS TO CONTINUE TO POUR INTO THE FORECAST AREA. THIS
MEANS A CONTINUOUS FALL OF TEMPERATURES FOR THE NEXT 24 HOURS...WITH
THE FALL SLOWED JUST SLIGHTLY DURING THE DAYTIME HOURS FROM THE AID
OF THE SUN. REGARDING SUNSHINE...CLOUD EVOLUTION TODAY IS A BIT
UNCERTAIN. THERE\S A FIGHT GOING ON BETWEEN THE SATURATION ALONG THE
COLD FRONTAL INVERSION AND SUBSIDENCE AND DRYING. THIS IS EVIDENT
NICELY ALONG AND WEST OF I-35 IN MN WHERE THERE ARE BANDS OF
CLEARING AND STRATUS. TRIED THE BEST TO PLAY THIS IN THE FORECAST
BUT MORE UPDATES OF SKY COVER IS LIKELY NEEDED. WOULD NOT BE
SURPRISED TO SEE A FEW FLURRIES COME OUT OF THE CLOUDS SINCE THE
CLOUD DECK SHOULD BE CONTAINED WITHIN THE DENDRITIC GROWTH ZONE.
HOWEVER...WITH LITTLE OMEGA PROGGED IN THE DENDRITIC GROWTH
ZONE...HAVE DECIDED NOT TO MENTION THE FLURRIES. CLEARING OF THE
SKIES LOOKS MORE LIKELY TONIGHT FROM NORTHWEST TO SOUTHEAST...THOUGH
A FEW MORE CLOUDS OF THE MID/HIGH LEVEL VARIETY MAY GET STUCK ACROSS
THE SOUTH.

REGARDING THE TEMPERATURE FALL...GOOD MODEL AGREEMENT EXISTS FOR
READINGS DROPPING INTO THE TEENS TO LOW 20S BY SUNSET...COLDEST IN
SOUTHEAST MN AND WARMEST IN FAR SOUTHWEST WI. FOR LOWS TONIGHT...
GOOD MODEL AGREEMENT EXISTS HERE TOO...DIPPING INTO THE SINGLE
DIGITS ABOVE ZERO IN RIVER VALLEY AREAS AND FAR SOUTHWEST WI TO THE
SINGLE DIGITS BELOW ZERO ELSEWHERE. THESE LOWS SEEM REASONABLE BASED
ON WHAT HAS BEEN OCCURRING OVER THE DAKOTAS NOW.

WIND CHILLS ARE NOT EXPECTED TO BE A HEADLINE ISSUE TODAY...THOUGH
10 TO 20 MPH NORTHWEST WINDS WITH HIGHER GUSTS SHOULD DROP THE WIND
CHILL DOWN INTO THE SINGLE DIGITS ABOVE AND BELOW ZERO BY SUNSET.
FOR TONIGHT...HOWEVER...A PERSISTENT 5 TO 15 MPH BREEZE COMBINED
WITH THE AFOREMENTIONED LOWS DO DROP WIND CHILLS TO THE ADVISORY
THRESHOLD OF -20F IN PORTIONS OF SOUTHEAST MN AND CENTRAL WI. GIVEN
HIGH CONFIDENCE ON BOTH WINDS AND TEMPERATURES...HAVE ISSUED A WIND
CHILL ADVISORY FOR AT LEAST TAYLOR COUNTY. ALSO CONSIDERED
DODGE...OLMSTED AND MOWER...BUT TO MAINTAIN A CLEANER HAZARD MAP
WITH MPX\S COLDER CRITERIA OF -25 AND AFTER COLLABORATION WITH
MPX...HAVE HELD OFF ISSUING FOR THESE COUNTIES. IF IT CONTINUES TO
LOOK JUST AS COLD OR COLDER...ADVISORIES WILL LIKELY BE ISSUED LATER
TODAY FOR DODGE...OLMSTED AND MOWER.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 318 AM CST SUN NOV 30 2014

OF THE ENTIRE FORECAST...MONDAY INTO MONDAY EVENING IS BY FAR THE
COLDEST PART. DESPITE MOSTLY CLEAR SKIES DURING THIS TIME
FRAME...FAVORED BY PRECIPITABLE WATER VALUES OF LESS THAN 1/10 OF AN
INCH...925MB TEMPS ARE PROGGED AT A CHILLY -16C SOUTH TO -20C NORTH
AT 18Z MONDAY. THESE READINGS ONLY SUPPORT HIGHS IN THE SINGLE
DIGITS TO TEENS ABOVE ZERO. THE CENTER OF THE ARCTIC HIGH PRESSURE
AREA CURRENTLY OVER MONTANA THEN SLIDES OVER THE FORECAST AREA AT
00Z TUESDAY...ALLOWING TEMPERATURES TO PLUMMET AFTER SUNSET. A DROP
OF 10 DEGREES BETWEEN 21Z MON AND 00Z TUE SUGGESTED BY THE 30.00Z
REGIONAL CANADIAN IS EASILY PLAUSIBLE. THE AMOUNT OF DROP IS
IMPORTANT AS THE LOW TEMPERATURE WILL OCCUR IN THE EVENING. GUIDANCE
IS IN GOOD AGREEMENT OF THE SURFACE HIGH QUICKLY SHIFTING OFF TO THE
EAST WITH A TIGHT PRESSURE GRADIENT IN PLACE BY 12Z TUESDAY. THAT
GRADIENT WILL INCREASE A RETURN FLOW BREEZE...ESPECIALLY ACROSS
WESTERN PORTIONS OF THE FORECAST AREA...CAUSING TEMPERATURES TO
CLIMB. ITS POSSIBLE SOUTHEAST MINNESOTA AND CENTRAL WISCONSIN RUN
INTO WIND CHILL ADVISORY ISSUES AGAIN AS THE BREEZE COMBINES WITH
THE INITIALLY COLD READINGS.

FOR TUESDAY INTO WEDNESDAY...THE FOCUS IS ON A SHORTWAVE TROUGH
CURRENTLY IN THE GULF OF ALASKA. MODELS REMAIN CONSISTENT IN DRIVING
THIS TROUGH ACROSS THE NORTHERN PLAINS ON TUESDAY AND ACROSS THE
FORECAST AREA EARLY WEDNESDAY. AHEAD OF THE TROUGH...CONTINUED
RETURN FLOW FROM MONDAY NIGHT WILL HELP PUSH 925MB TEMPS BACK UP TO
AS MUCH AS -4 TO -6C BY 00Z WEDNESDAY. ALTHOUGH MID AND HIGH CLOUDS
LOOK TO BE ON THE INCREASE ASSOCIATED WITH PACIFIC MOISTURE
STREAMING AHEAD OF THE TROUGH...THE WARM ADVECTION SHOULD HELP BRING
TEMPERATURES UP INTO THE 20S FOR HIGHS. A FEW SPOTS SUCH AS RIVER
VALLEYS MAY EVEN APPROACH FREEZING. COLD FRONTAL PASSAGE
ACCOMPANYING THE TROUGH LOOKS TO PASS THROUGH THE AREA TUESDAY
NIGHT. MAYBE A LITTLE LIGHT SNOW FALLS NORTH OF I-94 WITH ITS
PASSAGE OTHERWISE DRY CONDITIONS SHOULD CONTINUE. SOME COLDER AIR
FOLLOWS FOR WEDNESDAY...THOUGH THE BULK OF THE COLDER AIR STAYS
NORTH OF THE FORECAST AREA. 925MB TEMPS ONLY FALL TO -5 TO -9C SO
READINGS ON WEDNESDAY MAY ONLY BE SLIGHTLY COLDER THAN TUESDAY.

FOR THURSDAY INTO THE WEEKEND...THE UPPER FLOW TURNS MORE QUASI-
ZONAL...FAVORING A FLOW OF PACIFIC AIR ACROSS THE U.S. AND THUS
WARMER CONDITIONS. IN FACT...BY THE WEEKEND...WE SHOULD BE BACK UP
ABOVE NORMAL AS 925MB TEMPS CLIMB BACK TO OR ABOVE 0C. THERE IS ONE
SHORTWAVE MOVING THROUGH THE FLOW BETWEEN THURSDAY AND FRIDAY.
MODELS HAVE OSCILLATED BACK AND FORTH ON WHETHER THIS SHORTWAVE CAN
PRODUCE PRECIPITATION. 30.00Z GFS AND ECMWF HAVE TRENDED DRIER
WHEREAS THE CANADIAN STILL DRIVES SOME LIGHT SNOW THROUGH. TEND TO
BELIEVE A DRIER SOLUTION WILL PAN OUT GIVEN A SURFACE RIDGE IN
PLACE. OTHERWISE...HIGH PRESSURE CONTINUES TO DOMINATE...YIELDING
DRY CONDITIONS.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1119 PM CST SAT NOV 29 2014

THE COLD FRONT CONTINUES TO MOVE ACROSS THE AREA AND IS NOW EAST
OF BOTH TAF SITES. THE DRIER AIR LAGS BEHIND THE FRONT...WHICH HAS
ALLOWED THE TEMPERATURE TO FALL CLOSE TO THE DEW POINT AND FOR
FOG TO DEVELOP. THE DRIER AIR WAS WORKING ACROSS CENTRAL MINNESOTA
AND ONCE IT SPREADS IN...THE FOG PRETTY MUCH DISSIPATES. HAVE
TRIED TO SHOW A PERIOD OF IFR CONDITIONS IN THIS FOG AND LOW
CLOUDS FOR BOTH SITES UNTIL THE DRIER MOVES IN AND ALLOWS THE
VISIBILITY TO RETURN TO VFR WITH MVFR CEILINGS. THE BACK EDGE OF
THE MVFR CLOUDS CONTINUES TO WORK EAST ACROSS THE DAKOTAS THIS
EVENING. THE 30.03Z RAP REMAINS VERY AGGRESSIVE IN SPREADING THIS
CLEARING INTO BOTH TAF SITES EITHER LATE TONIGHT OR EARLY SUNDAY
MORNING WHILE THE 30.00Z NAM STILL WANTS TO HOLD ONTO THE LOW
CLOUDS AND MOISTURE THROUGH ALL OF SUNDAY. FOR NOW...WILL STAY
WITH THE PREVIOUS TRENDS OF SCATTERING OUT THE CLOUDS LATE SUNDAY
MORNING. STILL EXPECT TO HAVE GOOD LOW LEVEL LAPSE RATES DEVELOP
BEHIND THE FRONT TO ALLOW GUSTS TO BEGIN OVERNIGHT AND THEN
CONTINUE INTO SUNDAY EVENING.
