AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
220 PM CDT THU APR 4 2013

.SHORT TERM...(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 220 PM CDT THU APR 4 2013

SURFACE MAP THIS AFTERNOON HAS THE COLD FRONT RESPONSIBLE FOR
ISOLATED SHOWERS TODAY EXITING THE AREA...POSITIONED FROM JUST SOUTH
OF GREEN BAY THROUGH BOSCOBEL WI AND THEN INTO CENTRAL IA. BEHIND THIS
FRONT...HIGH PRESSURE WAS NOSING SOUTHEAST OUT OF MANITOBA INTO THE
UPPER MISSISSIPPI RIVER VALLEY REGION. OTHERWISE...SKIES WERE MOSTLY
SUNNY WITH TEMPERATURES IN THE MIDDLE 40S TO MIDDLE 50S.
MEANWHILE...WATER VAPOR IMAGERY WAS SHOWING A VIGOROUS TROUGH OF LOW
PRESSURE MAKING ITS WAY ONTO THE WEST COAST. THIS WILL BE OUR
WEATHER-MAKER FOR LATE FRIDAY AFTERNOON THROUGH SATURDAY EVENING.

04.12Z NCEP MODELS AS WELL AS THE LATEST ECMWF/GEM IN GOOD AGREEMENT
WITH UPPER LEVEL/SURFACE WEATHER FEATURES.

FOR TONIGHT...LOOKING FOR MOSTLY CLEAR SKIES WITH NORTHWEST WINDS
DIMINISHING/BECOMING CALM OVERNIGHT AS A RIDGE OF HIGH PRESSURE
SETTLES OVERHEAD. OVERNIGHT LOWS EXPECTED TO BOTTOM OUT MOSTLY IN
THE 20S. HOWEVER...LOWER LYING FAVORED COLD SPOTS SUCH AS DIAMOND
LAKE IN TAYLOR COUNTY WILL LIKELY DIP INTO THE TEENS.

FOR FRIDAY...WILL BE WATCHING AN AREA OF LOW PRESSURE MAKE ITS WAY
OUT OF THE INTERMOUNTAIN WEST INTO THE NORTHERN/CENTRAL
PLAINS...WITH A WARM FRONT EXTENDING THROUGH CENTRAL IA. A FAIRLY
STRONG WING OF 850-700MB ISENTROPIC LIFT/MOISTURE TRANSPORT DEVELOPS
AHEAD OF THE LOW/WARM FRONT INTO THE DAKOTAS/CENTRAL MN. THIS
FORCING DEVELOPS A NW-SE BAND OF RAIN WHICH WILL WORK INTO THE
NORTHWEST PORTIONS OF THE FORECAST AREA BY LATE IN THE AFTERNOON.
OTHERWISE...LOOK FOR INCREASING/THICKENING CLOUD COVER THROUGH THE
DAY WITH HIGHS TOPPING OFF IN THE LOWER 40S ACROSS NORTH CENTRAL
WI...TO THE LOWER 50S ACROSS PORTIONS OF NORTHEAST IA INTO FAR
SOUTHWEST WI.

PLAN ON RAIN TO SPREAD INTO THE AREA FRIDAY NIGHT AS THE LOW PUSHES
TOWARD SOUTHERN MN. ACROSS CLARK AND MAINLY TAYLOR COUNTY IN NORTH
CENTRAL WI...THERMAL PROFILES SUPPORT A MIX OF RAIN/SLEET/SNOW WITH
1 TO 2 INCHES OF SNOW ACCUMULATION POSSIBLE OVERNIGHT. THE HIGHEST
SNOW AMOUNTS ARE EXPECTED TO OCCUR NORTH OF HIGHWAY 64 IN TAYLOR
COUNTY. ALSO CANNOT RULE OUT ISOLATED POCKETS OF FREEZING RAIN
TOWARD MORNING AS SURFACE TEMPERATURES LOWER TO AROUND 32 DEGREES.
BELIEVE THIS WILL BE FAIRLY BRIEF THOUGH. ACROSS THE REST OF THE
AREA...RAIN IS EXPECTED WITH OVERNIGHT LOWS IN THE MIDDLE 30S TO
LOWER 40S.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 220 PM CDT THU APR 4 2013

LOW PRESSURE WILL CONTINUE TO TRACK EAST ACROSS SOUTHERN WI SATURDAY
WITH RAIN CONTINUING ACROSS MOST OF THE AREA. SOME MID-LEVEL
INSTABILITY ALSO INDICATED BY NAM WITH 2-5KM MUCAPE REACHING AROUND
350J/KG FOR SOME ISOLATED THUNDER. THIS LOOKS TO BE MAINLY ALONG AND
SOUTH OF I-90. OTHERWISE...A RESPECTABLE SLUG OF RAIN IN STORE FOR
AREAS MAINLY ALONG/NORTH OF I-94 WITH ANOTHER 1/4 TO 1/2 INCH ON TOP
OF WHAT FELL FRIDAY NIGHT. THIS WILL LIKELY CAUSE SOME HYDROLOGY
ISSUES ACROSS AREAS THAT HAVE A SNOWPACK YET ACROSS CENTRAL/NORTH
CENTRAL WI. MORE DETAIL IS GIVEN IN THE HYDROLOGY SECTION BELOW.

LOOK FOR THE RAIN TO COME TO AN END BY SATURDAY MIDNIGHT AS THE LOW
TRACK INTO THE GREAT LAKES REGION. COOLER AIR FILTERING IN ON THE
BACKSIDE OF THE LOW MAKE CAUSE THE RAIN TO MIX WITH SOME SNOW BEFORE
ENDING...BUT LITTLE IF ANY ACCUMULATION EXPECTED.

HIGH PRESSURE BUILDS IN OVERNIGHT SATURDAY NIGHT INTO SUNDAY FOR A
BRIEF DRY PERIOD. LOOK FOR LOWS SATURDAY NIGHT IN THE UPPER 20S TO
THE MIDDLE 30S...AND HIGHS ON SUNDAY IN THE 40S AND LOWER 50S.

GFS AND THE LATEST ECMWF/GEM BRING A WEAK MID-LEVEL TROUGH AND
SURFACE LOW ACROSS THE AREA SUNDAY NIGHT INTO MONDAY FOR ANOTHER
CHANCE OF PRECIPITATION. THIS LOOKS TO BE MAINLY A RAIN-MAKER...
HOWEVER THERMAL PROFILES MAY BE COOL ENOUGH NORTH OF I-94 FOR A MIX
OF RAIN/SNOW. LOWS SUNDAY NIGHT ARE EXPECTED TO DIP INTO THE 31-39
DEGREE RANGE WITH HIGHS ON MONDAY IN THE MIDDLE 40S TO MIDDLE 50S.

FOR TUESDAY THROUGH THURSDAY...04.12Z GFS AND 04.00Z ECMWF CONTINUE
TO BE AT ODDS WITH HANDLING OF JET ENERGY/UPPER LEVEL PATTERN. THE
GFS IS MORE PROGRESSIVE OVERALL WITH MORE PHASING WITH THE NORTHERN
STREAM. IT GENERATES STRONG CYCLOGENESIS OVER THE SOUTHERN PLAINS
TUESDAY AND TAKING THE LOW THROUGH SOUTHEAST WI WEDNESDAY AND
EVENTUALLY INTO EASTERN QUEBEC BY THURSDAY. MEANWHILE...THE ECMWF
MAINTAINS A MORE CUTOFF SOLUTION AT FIRST OVER CO/AZ ON WED...THEN
EVENTUALLY BRING THE LOW EAST/NORTHEAST INTO THE OHIO RIVER VALLEY
THURSDAY. BOTH MODELS DO BRING PRECIPITATION INTO THE AREA WITH THE
GFS PROVIDING MORE NORTHWARD EXTENT. MODEL CONSENSUS APPROACH YIELDS
FAIRLY GOOD PRECIPITATION CHANCES THROUGH THE PERIOD. APPEARS
PRECIPITATION TYPE MAY BE DIURNALLY DRIVEN WITH RAIN/SNOW MIX
MONDAY/TUESDAY/WEDNESDAY NIGHT AND RAIN DURING THE DAYTIME HOURS.
OTHERWISE...TEMPERATURES LOOK TO BE ON THE DOWN TREND THROUGH THE
WEEK WITH HIGH GOING FROM THE MIDDLE 40S TO MIDDLE 50S ON
TUESDAY...INTO THE UPPER 30S/MIDDLE 40S BY THURSDAY.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY)
ISSUED AT 1225 PM CDT THU APR 4 2013

THE COLD FRONT HAS PUSHED THROUGH KRST AND KLSE. EXPECT A WEST TO
NORTHWEST WIND BETWEEN 10 AND 18 KNOTS AT BOTH SITES THROUGH THE
AFTERNOON....THEN DIMINISHING THIS EVENING AND GRADUALLY COMING
AROUND THE SOUTHEAST BY FRIDAY MORNING. VFR CEILINGS WILL CLEAR
EARLY THIS AFTERNOON...WITH CLEAR SKIES THEN EXPECTED THROUGH THE
REMAINDER OF THE TAF PERIOD.

&&

.HYDROLOGY...
ISSUED AT 220 PM CDT THU APR 4 2013

LOOKING AT HYDROGRAPHS ACROSS THE AREA SHOWS RIVERS AND STREAMS
RUNNING WITHIN BANK FLOWS WITH A FEW HIGHER THAN NORMAL GIVEN THE
SNOW MELT. THE SYSTEM AFFECTING THE AREA FRIDAY NIGHT THROUGH
SATURDAY HAS THE POTENTIAL TO PRODUCE 1/2 TO 1 INCH OF RAINFALL OVER
PORTIONS OF THE AREA...MAINLY NORTH OF INTERSTATE 94. SOME OF THIS
LIQUID MAY GO INTO SOME SNOWFALL FRIDAY NIGHT ACROSS CLARK/TAYLOR
COUNTIES. HOWEVER...ANY SNOWFALL WILL CHANGE TO RAIN DURING THE DAY
SATURDAY. IN ADDITION...WARMING TEMPERATURES SATURDAY WILL MELT THE
FALLEN SNOW AND ALSO PRODUCE MELTING OF THE EXISTING SNOW
PACK. AT THIS TIME...IT APPEARS THE HIGHEST CONCENTRATION OF
RAINFALL AND LIQUID FROM SNOWMELT WILL OCCUR FROM WEST CENTRAL INTO
NORTH CENTRAL WISCONSIN. THIS WILL LIKELY HAVE A SIGNIFICANT IMPACT
ON RIVERS ACROSS THAT AREA SUCH AS THE BLACK...TREMPEALEAU...AND
BUFFALO RIVERS. OTHER AREA RIVERS AND STREAMS WILL ALSO LIKELY BE
IMPACTED BY RAINFALL AND SNOWMELT. STAY UP TO DATE ON LATER
FORECASTS AND STATEMENTS CONCERNING THIS WEEKENDS WEATHER SYSTEM.
