AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
1239 PM CDT THU MAY 24 2012

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT
338 AM CDT THU MAY 24 2012

MAIN FORECAST CONCERNS THIS PACKAGE...WINDS TODAY...SHRA/TSRA
CHANCES THROUGH THE PERIOD...SEVERE THREAT THIS AFTERNOON/EARLY THIS
EVENING...TEMPERATURES.

06Z DATA ANALYSIS HAD LOW PRESSURE IN WESTERN ON AND IN THE OK
PANHANDLE. COLD FRONT BETWEEN THE TWO EXTENDED FROM NEAR KDLH TO
KOWA TO KOMA...MAKING ONLY SLOW PROGRESS EAST. FRONT AND COOLER AIR
WEST/NORTH OF IT REMAINED THE FOCUS FOR LIFT OF A VERY MOIST 925-
700MB BEING ADVECTED NORTH AHEAD OF A MID LEVEL SHORTWAVE TROUGH
LIFTING THRU THE CENTRAL PLAINS. WIDESPREAD SHRA/TSRA OCCURRING FROM
NEAR KDLH SOUTHWEST ACROSS MN TO NEB AND EASTERN CO...NORTH OF THE
FRONT AND OK LOW. BRISK SOUTH WINDS 10-20KT G25-30KTS WERE COMMON
ACROSS IA/SOUTHEAST MN/WESTERN WI IN THE TIGHTER PRESSURE GRADIENT
AHEAD OF THE FRONT.

24.00Z MODELS LOOK TO HAVE INITIALIZED WELL...BUT FOR GFS AGAIN SOME
5F TO 15F TOO HIGH WITH SFC DEW POINTS IN THE MOISTURE PLUME FROM
MN TO OK. SOLUTIONS QUITE SIMILAR WITH THEIR IMPACTS ON THE AREA FOR
TODAY THRU SAT NIGHT. DPROG/DT OF 500MB HGTS AT 24.00Z SHOWED MODEL
RUNS OF 22.00Z AND 23.00Z VERIFIED WELL ACROSS NOAM/EASTERN PAC
WITH ECMWF SHOWING THE BETTER RUN-TO-RUN CONSISTENCY AND A GENERAL
CONVERGENCE OF OTHER MODELS TOWARD ITS SOLUTION. MODELS HAVE TRENDED
STRONGER WITH THE SHORTWAVE TROUGH TO LIFT ACROSS THE REGION TODAY/
EARLY TONIGHT. GOOD CONSISTENCY WITH THE DEVELOPING MID LEVEL LOW
OVER THE WESTERN CONUS. GOOD CONSISTENCY WITH THE RISING HGTS/
RIDGING BUILDING OVER THE UPPER MIDWEST/NORTHERN PLAINS FRI/FRI
NIGHT...WHILE TREND IS A BIT FASTER WITH THE TROUGH STARTING TO LIFT
OUT OF THE WESTERN CONUS. TREND FAVORS FASTER OF EARLIER RUNS WITH
THE TROUGH LIFTING INTO THE NORTHERN PLAINS SAT/SAT NIGHT. ECMWF
WITH THE BETTER RUN-TO-RUN CONSISTENCY THRU THE SHORT-TERM THIS
CYCLE. CHECK OF OBS VS. MODEL DATA AT 06Z SHOWED GFS REMAINED 5-10F
TOO HIGH WITH SFC DEW POINTS IN THE PRE-FRONTAL/TROUGH MOISTURE
PLUME. OTHERWISE ALL WERE GOOD WITH THE SFC MASS FIELDS. PER WV
IMAGERY...NO MODEL APPEARED CLEARLY BETTER THAN THE OTHERS WITH THE
SHORTWAVE DETAILS IN THE CENTRAL/WESTERN NOAM TROUGH. SOME DETAILS
OF EACH PREFERRED AND OVERALL A MODEL BLEND MAY BE BEST. THAT SAID
AND MODELS CONTINUING TO CONVERGE TOWARD A TIGHTER COMPROMISE
SOLUTION THRU THE SHORT TERM...FAVORED THE MODEL/ENSEMBLE BLEND.
SHORT-TERM FCST CONFIDENCE AVERAGE TO GOOD THIS CYCLE.

IN THE SHORT TERM...FIRST CONCERN IS THE STRONG WINDS AGAIN TODAY
AND WILL ISSUE A WIND ADVISORY FOR ROUGHLY THE EAST 2/3 OF THE FCST
AREA FROM NOON TO 7 PM. THIS AREA WELL AHEAD OF THE FRONT/TROUGH
TODAY WITH HIGH EXPECTED TO REACH 80-85F...ALLOWING FOR MIXING TO
ABOUT 850MB. OVER THE WEST 1/3 OF THE FCST AREA WERE THERE WILL BE
MORE CLOUDS AND SHRA/TSRA LOOKING TO BE MORE COMMON DURING THE EARLY
AFTERNOON HOURS. PRESSURE GRADIENT ALSO BAGGIER OVER THE WEST 1/3
OF THE FCST AREA CLOSER TO THE FRONT THIS AFTERNOON...WITH THE LOW
TRACKING NORTH ALONG IT. WINDS AT THE TOP OF THE MIXED LAYER ACROSS
THE EAST 2/3 OF THE FCST AREA IN THE 40-50KT RANGE THIS AFTERNOON
ALONG WITH SFC GRADIENT WINDS OF 25 TO 30+MPH.

FRONT REMAINS THE FOCUS FOR A LINE OF STRONG TO SEVERE TSRA TO MOVE
ACROSS THE FCST AREA THIS AFTERNOON/EARLY THIS EVENING. FRONT WILL
MAKE LITTLE PROGRESS EAST TODAY UNTIL THE LOW MOVING NORTH ALONG IT
LIFTS INTO NORTHWEST WI. RATHER STRONG SFC-850MB FN CONVERGENCE
INDICATED WITH THE FRONT AS IT MOVES ACROSS LATE TODAY. THIS UNDER
MDT TO STRONG 400-200MB PV ADVECTION WITH THE PASSING SHORTWAVE.
0-3KM SHEAR IN THE 40-50KT RANGE WITH 0-6KM SHEAR IN THE 60-70KT
RANGE. QUESTION IS MID LEVEL WARM TEMPS AND CAPPING AND CAPE AHEAD
OF THE FRONT THIS AFTERNOON. DEBRIS CLOUDS FROM ONGOING CONVECTION
BEHIND THE FRONT WILL BE A PROBLEM FOR STRONG WARMING/
DESTABILIZATION THIS AFTERNOON...ESPECIALLY OVER THE WEST HALF OF
THE FCST AREA. MOST MODELS WITH A RATHER NARROW BAND OF ONLY 500-
1000 J/KG OF MU CAPE OVER WESTERN WI AHEAD OF THE FRONT THIS
AFTERNOON. THE STRONG SHEAR MAY OVERWHELM WHAT COULD BE LIMITED CAPE
AND ANY TSRA MAY STRUGGLE TO ORGANIZE OR BE TORN APART BY THE STRONG
SHEAR. SLIGHT RISK PER SWODY1 LOOKS GOOD FOR NOW GIVEN CONVERGENCE/
LIFT ALONG THE FRONT AND STRONGER DIVERGENCE ALOFT. ADDED MORE
TIMING DETAIL TO SHRA/TSRA CHANCES THRU THIS EVENING...WITH CHANCES
REMAINING 60-80 PERCENT THIS AFTERNOON INTO EARLY THIS EVENING.
REDUCED PRECIP CHANCES AFTER 03Z THIS EVENING WITH STRONG DRYING/
SUBSIDENCE/COOLING BEHIND THE FRONT.

WEAK AND COOLER/DRIER HIGH PRESSURE BUILDS IN FOR LATE TONIGHT/FRI.
LEFT FRI DRY FOR NOW...BUT SOME SIGNAL FOR MOISTURE TRANSPORT AND
THETA-E CONVERGENCE AROUND 700MB TO BE SPREADING QUICKLY OVER THE
AREA IN THE AFTERNOON. MAY YET NEED A SMALL -SHRA/TSRA CHANCE LATE
FRI AFTERNOON BUT LEFT IT DRY FOR NOW.

FRONT TO THE SOUTH STARTS TO RETURN NORTH AS A WARM FRONT FRI NIGHT
THEN LIFTS NORTH ACROSS THE AREA SAT/SAT NIGHT. SYNOPTIC SCALE
FORCING OF DEEPENING SOUTHERLY FLOW AND AN INCREASINGLY MOIST/
UNSTABLE AIRMASS BEING ADVECTED NORTH INTO AND OVER THE FRONTAL
BOUNDARY WILL PROVIDE SHRA/TSRA CHANCES FROM FRI NIGHT THRU SAT
NIGHT...UNTIL THE FRONT LIFTS NORTH OF THE FCST AREA. POTENTIAL ALSO
EXITS FOR SOME LOCALLY HEAVY RAINS DURING THIS TIME WITH PW VALUES
IN THE INFLOW AIRMASS IN THE 1.5 INCH RANGE AND POTENTIAL FOR 2K-4K
J/KG OF CAPE ALONG/SOUTH OF THE FRONT ON SAT. DEPENDING ON WHERE THE
FRONT ENDS UP DURING SAT AFTERNOON/EVENING THERE MAY BE A RISK OF
SEVERE STORMS IF THEY ARE ROOTED IN THE BOUNDARY LAYER NEAR THE
FRONT ITSELF. HOWEVER...HOW MUCH CONVECTION OCCURS NORTH OF THE
FRONT FRI NIGHT/SAT/SAT NIGHT WILL HAVE AN IMPACT ON HOW QUICKLY
THE FRONT MOVES NORTH. MORE WIDESPREAD CONVECTION AND RESULTING
BOUNDARY LAYER COOLING/COLD POOL GENERATION WILL TEND TO STALL THE
FRONT/S NORTHWARD PROGRESS...THUS SOME UNCERTAINTY WITH THE FRONTAL
POSITION...SHRA/TSRA CHANCES AND TEMPS BY SAT/SAT NIGHT. SHRA/TSRA
CHANCES FOR FRI NIGHT THRU SAT NIGHT MOSTLY IN THE 30-50 PERCENT
RANGE REASONABLE AT THIS TIME.

USED A BLEND OF NUMERICAL GUIDANCE HIGHS FOR TODAY THRU SAT NIGHT.
HIGHS SAT COULD END UP CONSIDERABLY COOLER THAN THOSE IN THE FCST
GRIDS IF CLOUDS/CONVECTION DOMINATE AND THE FRONT STAYS SOUTH OF
THE FCST AREA.

.LONG TERM...SUNDAY THROUGH WEDNESDAY
338 AM CDT THU MAY 24 2012

SIGNAL AMONG MEDIUM RANGE MODELS REMAINS CONSISTENT THAT THE FRONT
WILL LIFT NORTH OF THE FCST AREA FOR SUN. AREA WOULD BE IN THE VERY
WARM...CAPPED WARM SECTOR WITH THE MAIN SHRA/TSRA CHANCES WEST/NORTH
OF THE FCST AREA. GOOD CONSISTENCY CONTINUES SUN NIGHT/MON FOR LOW
PRESSURE...IN RESPONSE TO THE TROUGH LIFTING OUT OF THE ROCKIES...
TO BE LIFTING NORTHEAST THRU THE PLAINS AND TOWARD ONT. THIS LOW
WILL DRAG A COLD FRONT EAST ACROSS THE AREA SUN NIGHT/MON...INTO
WHAT SHOULD BE A MOIST/UNSTABLE AIRMASS OVER THE AREA. SHRA/TSRA
CHANCES INCREASE AGAIN FOR LATER SUN NIGHT/MEMORIAL DAY WITH THE
PASSAGE OF THIS FRONT. MODELS HAVE TRENDED A BIT FASTER WITH THIS
FRONTAL PASSAGE. THE MAIN RAIN CHANCE ON MEMORIAL DAY MAY BE IN THE
MORNING WITH THE AFTERNOON TRENDING COOLER/DRY BEHIND THE FRONT AS
HIGH PRESSURE BUILDS IN. TUE/WED TRENDING EVEN COOLER WITH NORTH TO
NORTHWEST SFC-MID LEVEL FLOW OVER THE UPPER MIDWEST. A WEAK
SHORTWAVE OR TWO RIPPLING THRU THE NORTHWEST MID LEVEL FLOW LOOK TO
BRING SMALL -SHRA/TSRA CHANCES TO THE AREA FOR TUE/WED. MODEL/
ENSEMBLE CONSENSUS DATA IN THE DAY 4-7 FCST GRIDS APPEARS WELL
TRENDED FOR NOW WITH ONLY MINOR ADJUSTMENTS MADE TO BETTER BLEND
WITH NEIGHBORING GRIDS.

.AVIATION...THROUGH 18Z FRIDAY
1238 PM CDT THU MAY 24 2012

MAIN AVIATION CONCERNS IS TIMING OF SURFACE COLD FRONT AND
ASSOCIATED SHOWER AND THUNDERSTORMS DEVELOPMENT ALONG THE FRONT THIS
AFTERNOON INTO THIS EVENING. LATEST DETERMINISTIC 24.12Z MODELS SHOW
SHOWERS AND THUNDERSTORMS TO DEVELOP ALONG THE FRONT AROUND 19Z AND
MOVE INTO THE RST TAF SITE APPROXIMATELY OR SHORTLY AFTER 19Z AND 22Z AT
LSE. MODELS INDICATE SOME OF THE THUNDERSTORMS COULD BE SEVERE ALONG
THE FRONT...WITH THE MAIN THREAT BEING STRONG WINDS. OUT AHEAD OF
THE FRONT...THE COMBINATION OF A TIGHTENING PRESSURE GRADIENT AND
MIXING OF WINDS ALOFT DOWN TO THE SURFACE WILL CREATE WINDY
CONDITIONS...ESPECIALLY AT LSE. SUSTAINED WINDS OF 20 TO 25 KNOTS
WITH GUST UP TO 38 KNOTS CAN BE EXPECTED THROUGH THIS EVENING AT
LSE. AFTER FRONTAL PASSAGE LOWER CEILINGS ARE EXPECTED AT BOTH TAF
SITES WITH CEILINGS LOWERING TO MVFR RANGE FOR A SHORT TIME. HIGH
PRESSURE BUILDS INTO THE AREA AFTER 04Z FRIDAY AND SKIES WILL CLEAR
AND WINDS WILL DIMINISH AT BOTH RST AND LSE TAF SITES.
