AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
314 PM CST MON FEB 18 2013

.SHORT TERM...TONIGHT THROUGH THURSDAY
314 PM CST MON FEB 18 2013

THE MAIN FOCUS THROUGH MID WEEK IS WITH THE LOW WIND CHILLS
TOMORROW MORNING FOLLOWED BY THE START OF THE NEXT WEATHER SYSTEM
THAT IS EXPECTED TO BRING AN ACCUMULATING SNOW OF 2 TO 5 INCHES
TO THE REGION.

CURRENTLY...TWO SYSTEMS ARE STARTING TO PHASE TOGETHER ACROSS THE
REGION WITH A SOUTHERN STREAM MID LEVEL SHORT WAVE TROUGH MERGING
WITH A NORTHERN STREAM SHORT WAVE TROUGH. THIS HAS LEAD TO THE
DEVELOPMENT OF THREE BANDS OF PRECIPITATION ACROSS THE REGION. THE
FIRST IS A POCKET OF SNOW SURGING NORTHWARD ALONG THE SOUTHERN
STREAM TROUGH...THE SECOND IS A NARROW BAND OF DRIZZLE THAT
PRECEDES THE THIRD AREA WHICH IS A MORE INTENSE...YET BRIEF...BAND
OF SNOW. THINKING THAT AS THESE TWO SHORT WAVES CONTINUE TO MERGE
OVER THE NEXT FEW HOURS THAT THE DRIZZLE THREAT WILL ERODE WITH
THE THERMAL PROFILE SATURATING DEEP ENOUGH THAT ICE WILL BE
PRODUCED AREA-WIDE. 18.12Z HI-RES ARW/NMM/HRRR GUIDANCE SHOWS THIS
BAND SHIFTING TO THE EAST QUICKLY TO THE EAST AND SHOULD BE OUT OF
WESTERN WISCONSIN BETWEEN 00-03Z TONIGHT. SNOW AMOUNTS WILL REMAIN
ON THE LIGHT SIDE AT LESS THAN AN INCH AS THIS FEATURE MOVES
THROUGH. SOME LIGHT SNOW/FLURRIES WILL LINGER INTO TOMORROW
MORNING IN THE CYCLONIC FLOW.

THE FOCUS THEN SHIFTS TO THE COMBINATION OF STRONG WINDS AND
DROPPING TEMPERATURES OVERNIGHT INTO TOMORROW MORNING WHICH HAS
LED TO THE ISSUANCE OF A WIND CHILL ADVISORY FOR PORTIONS OF
SOUTHEAST MINNESOTA AND NORTHEAST IOWA. WITH THE TIGHTENING
PRESSURE GRADIENT SETTING UP ACROSS THE REGION ON THE BACK SIDE OF
THE SYSTEM...19.12Z NAM/GFS BUFKIT SOUNDINGS SHOW THAT WINDS WILL
BE ON THE INCREASE OUT OF THE WEST-NORTHWEST TONIGHT WITH
SUSTAINED WINDS AROUND 20-25MPH AND GUSTS UP TO 35 MPH AND UNDER
WIND ADVISORY CRITERIA. AS TEMPERATURES CONTINUE TO DROP INTO THE
SINGLE DIGITS IN THE WIND PRONE AREAS OF SOUTHEAST MINNESOTA AND
NORTHEAST IOWA...EXPECT THAT WIND CHILL INDICES WILL DROP DOWN TO
AROUND -25F TOWARD SUNRISE AND LINGER UNTIL ABOUT NOON. THE
COLDEST AIR DOES NOT GET IN UNTIL AFTER 9Z TOMORROW MORNING...SO
WENT WITH THAT AS THE START TIME WHILE LOCATIONS FURTHER TO THE
WEST IN MINNESOTA AND IOWA WILL LIKELY BE MAKING IT DOWN SOONER.
WITH THESE TEMPERATURES RAPIDLY DROPPING OVERNIGHT...MAY HAVE SOME
SLICK SPOTS DEVELOP WHERE ANY RUN OFF FROM MELTING SNOW GOES ACROSS
ROAD WAYS AND RE-FREEZES.

HIGH PRESSURE WILL THEN SETTLE IN ACROSS THE REGION THROUGH MID
WEEK...WHICH WILL KEEP THE COLD AIR IN UNTIL THURSDAY MORNING.
SOME SPOTS MAY APPROACH WIND CHILL ADVISORY CRITERIA AGAIN ON
WEDNESDAY MORNING...BUT CONFIDENCE IS NOT AS HIGH THAT IT WILL BE
NECESSARY WITH WINDS DIMINISHING THROUGH THE MORNING HOURS ON
WEDNESDAY.

SNOW WILL THEN MOVE INTO THE REGION ON THURSDAY AS THE NEXT SYSTEM
MOVES INTO THE REGION. NOT A WHOLE LOT OF CHANGES SEEN WITH THE
19.12Z GUIDANCE...BUT THEY ARE TRENDING A TAD SLOWER THAN THE
PREVIOUS RUNS. THIS STILL LOOKS LIKE A WEAKENING SYSTEM AS IT
APPROACHES FROM THE SOUTHWEST WITH THE MAIN FORCING STAYING OUT
WELL TO THE WEST WHERE THE MAIN 500MB TROUGH LIFTS NORTH. THROUGH
THURSDAY AFTERNOON...IT APPEARS THAT MOST OF THE SNOW SHOULD
REMAIN IN PORTIONS OF SOUTH CENTRAL MINNESOTA TO EASTERN IOWA.

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY
314 PM CST MON FEB 18 2013

THE MAIN SNOW BAND WILL LIFT NORTH THROUGH THE REGION ON THURSDAY
NIGHT AS THE MAIN MID LEVEL TROUGH SWINGS NORTHWARD. THIS WILL
YIELD A BRIEF PERIOD OF MODERATE SNOW THAT WILL LIKELY BE
WEAKENING AS IT TRACKS TO THE NORTHEAST. QPF AMOUNTS APPEAR TO
RANGE FROM AROUND 0.35 INCHES IN NORTHEAST IOWA TO AROUND 0.15
INCHES IN NORTH CENTRAL WISCONSIN BY THE TIME THE SYSTEM ENDS ON
FRIDAY. WITH SNOW RATIOS EXPECTED TO BE IN THE 10/15:1 RANGE...IT
LOOKS LIKE THE HIGHEST SNOW ACCUMULATIONS SHOULD BE ACROSS
NORTHEAST IOWA AND PORTIONS OF SOUTHEAST MINNESOTA AND FAR
SOUTHWEST WISCONSIN WHERE 3-5 INCHES COULD FALL. SNOW AMOUNTS ARE
EXPECTED TO DECREASE TO THE NORTHEAST WITH A 2-4 INCH RANGE
EXPECTED INTO NORTH CENTRAL WISCONSIN.

LIGHT SNOW WILL COME TO AN END FROM SOUTH TO NORTH FRIDAY NIGHT
INTO SATURDAY WITH A BRIEF RIDGE OF HIGH PRESSURE EXPECTED TO MOVE
ACROSS THE REGION NEXT WEEKEND. ANOTHER SYSTEM IS THEN FORECAST TO
OCCUR SOMETIME BETWEEN SUNDAY AND TUESDAY WITH THE 19.12Z
GFS/ECMWF/FIM MODELS ARE SHOWING DIFFERENT TIMING IN REGARD TO
WHEN THE LOW PASSES THROUGH. THE 19.12Z GFS IS THE FASTEST WITH
HAVING THE LOW COME THROUGH ON SUNDAY WHILE THE 19.12Z ECMWF IS
THE SLOWEST WITH HAVING IT COME THROUGH ON MONDAY. THE 19.12Z FIM
SEEMS TO BE A BLEND IN BETWEEN THE TWO AND MAY BE A GOOD
COMPROMISE. THE TRACK THOUGH SEEMS TO BE SIMILAR WITH TAKING THE
CENTER OF THIS LOW OFF TO THE WEST OF THE REGION...WHICH PROBABLY
LEAVES US MORE INTO A MIXED P-TYPE.

&&

.AVIATION...THIS AFTERNOON INTO TUESDAY
1145 AM CST MON FEB 18 2013

DEEPENING LOW PRESSURE OVER NORTHEAST MN WITH A TROUGH/FRONT TO THE
SOUTH INTO MO WILL CONTINUE TO MOVE EAST-SOUTHEAST ACROSS THE REGION
THIS AFTERNOON/TONIGHT. SOUTH WINDS AHEAD OF THE TROUGH/FRONT WILL
SWING TO THE NORTHWEST BEHIND IT...AND INCREASE INTO THE 20KT G30KT
RANGE FOR LATER THIS AFTERNOON...TONIGHT AND TUE MORNING.

BEHIND THE FRONT...COLDER AIR WILL SPREAD SOUTHEAST ACROSS THE
AREA...WITH TEMPS HEADING TOWARD 0F BY TUE MORNING. BEHIND THE FRONT
CIGS/VSBYS WILL LOWER INTO MVFR/IFR WITH BR AS POST-FRONTAL LOW
LEVEL MOISTURE SPREADS ACROSS THE AREA. FCST REMAINS A BIT UNCERTAIN
AS FAR AS PRECIP...BOTH OCCURRENCE AND TYPES AT THE TAF SITES THIS
AFTERNOON/EVENING. PLENTY OF LOW LEVEL DRY AIR IN PLACE AHEAD OF THE
FRONT...NEEDING TO BE OVERCOME BEFORE MUCH IN THE WAY OF PRECIP
WOULD EVEN OCCUR. APPEARS DEEPER SATURATION IS BEHIND THE FRONT IN
THE COLDER AIR WHERE ANY PRECIP WOULD MAINLY BE SNOW. DID LEAVE A
BRIEF PERIOD OF -DZSN AT THE TAF SITES THIS AFTERNOON UNTIL DEEPER
SATURATION/ICE IN THE CLOUD/MOISTURE LAYER IS MORE CERTAIN. BY THE
TIME THE DEEPER MOISTURE SPREADS ACROSS THE TAF SITES...STRONGER/
DEEPER OF THE LIFT HAS MOVED EAST OF THE AREA. APPEARS ANY -SN LATE
THIS AFTERNOON/EVENING WILL MAINLY BE IN THE 22Z-02Z WINDOW...WITH
MAINLY -SHSN/FLURRIES MUCH OF TONIGHT IN DEEP...COOLING CYCLONIC
FLOW. GIVEN THIS...CIGS EXPECTED TO STAY MVFR WELL INTO TUE.
