AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
310 PM CDT TUE AUG 23 2011

.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT

MAIN FORECAST CONCERNS ANY LINGERING SHRA/TSRA CHANCE THIS EVENING
AND SMALL SHRA/TSRA CHANCES WITH NEXT FRONT FRI/FRI NIGHT...
TEMPERATURES THROUGH THE PERIOD.

DATA ANALYSIS AT 18Z HAD A WEAK SFC TROUGH NORTH-SOUTH THRU MN WITH
THE MAIN TROUGH/FRONT STILL IN THE EASTERN DAKOTAS. THE REMNANT
CONVECTIVE COMPLEX WAS MOVING THRU NORTHEAST IL. AREA RADARS AND
VIS/WV IMAGERY SHOWED A TWIST/MID LEVEL LOW SOUTH OF DULUTH.
WESTERLY COMPONENT TO THE FLOW AT/ABOVE 925MB AND SUBSIDENCE IN WAKE
OF THE CONVECTIVE COMPLEX CLEARED OUT THE CLOUDS OVER MUCH OF
IA/SOUTHERN MN/WESTERN WI THRU THE LATE MORNING HOURS. SOME
SOUTHWEST 925-850MB FLOW ADVECTING OVER THE OLD OUTFLOW BOUNDARY
PRODUCING CU/STRATO-CU OVER WEST PORTION OF THE FCST AREA AND NEARBY
AREAS EARLY THIS AFTERNOON...GENERALLY STUCK UNDER AN INVERSION NEAR
850MB WITH SFC BASED CIN VALUES IN THE 100-200 J/KG RANGE. STRONGEST
OF SFC BASED CAPE...2K-4K J/KG...REMAINED WEST OF THE FCST AREA...
WITH MINIMAL CAPE EAST OF MS RIVER.

23.12Z LOOK TO HAVE INITIALIZED WELL AND OFFER REASONABLY SIMILAR
SOLUTIONS FOR TONIGHT INTO FRI NIGHT. SOME OF THE BIGGER DIFFERENCES
ARE WITH CONVECTIVE POTENTIAL LATE THIS AFTERNOON/EARLY THIS
EVENING. DPROG/DT OF 500MB HGTS AT 23.12Z SHOWED MODEL RUNS OF
21.12Z AND 22.12Z VERIFIED...QUITE WELL ACROSS NOAM...FAVORING
STRONGER OF EARLIER MODELS WITH THE SHORTWAVE TROUGH OVER MN. MODELS
CONVERGING TOWARD A TIGHTER CONSENSUS SOLUTION TONIGHT/WED AS THE
SHORTWAVE ENERGY OVER ALB/SASKAT DROPS INTO THE NORTHERN GREAT
LAKES...ALSO FAVORING STRONGER OF EARLIER MODEL RUNS. BETTER
CONSENSUS WED NIGHT/THU AS THE TROUGH PROGRESSES INTO THE EASTERN
CONUS AND SHORTWAVE RIDGING BUILDS OVER THE UPPER MIDWEST. TREND
FAVORS A SLIGHTLY SLOWER PROGRESSION OF THE TROUGH. TREND FAVORS
SLIGHTLY STRONGER WITH THE NEXT TROUGH TO DROP INTO THE NORTHERN
GREAT LAKES LATE FRI/FRI NIGHT WITH BETTER MODEL CONSENSUS ON
TIMING. CHECK OF OBS VS. MODEL DATA AT 18Z SHOWED GENERALLY GOOD
WITH THE SFC MASS FIELDS OVER THE NORTH-CENTRAL CONUS. MODELS ALL A
BIT HIGH 2F-5F WITH SFC DEW POINTS OVER WESTERN WI/EASTERN IA/MN.
PER WV IMAGERY...GEM/ECMWF LOOKED BETTER WITH THE SHORTWAVE ENERGY
OVER NORTHEAST MN/NORTHWEST WI...AND WITH WEAK FEATURES OVER
NORTHERN NEB. ECMWF/GFS GENERALLY BETTER WITH THE 12Z-18Z PRECIP
OVER THE REGION. WITH A BETTER MODEL CONSENSUS AND NO CLEAR
PREFERRED DETERMINISTIC RUN...FAVORED A MODEL/ENSEMBLE BLEND THIS
CYCLE. SHORT-TERM FCST CONFIDENCE AVERAGE TO GOOD THIS CYCLE.

IN THE SHORT TERM...STRONGER OF LOW LEVEL THERMO-DYNAMIC FORCING/
LIFT EXIT EAST OF THE AREA RATHER QUICKLY LATE THIS AFTERNOON/EARLY
THIS EVENING. THIS AS THE NORTHWEST WI SHORTWAVE/COMPACT UPPER LOW
AND PV ADVECTION/DIVERGENCE ALOFT AHEAD OF IT EXIT EAST OF THE AREA
AS WELL. WITH THE MDT/STRONG CAPPING NEAR 850MB IN PLACE AND EXITING
OF THE FORCING/LIFT...LEFT SHRA/TSRA CHANCES FOR EARLY THIS EVENING
IN THE 20-30 PERCENT RANGE...TRENDING TO A 20 PERCENT CHANCE OVER
THE SOUTHEAST THIRD OF THE FCST AREA FOR THE LATE EVENING. SHOULD
ANY TSRA DEVELOP LATE THIS AFTERNOON/EARLY THIS EVENING...A SEVERE
STORM IS POSSIBLE. SEE SWODY1 FOR DETAILS. MAIN SFC TROUGH/FRONT
PUSHES THRU THE AREA LATER THIS EVENING/OVERNIGHT WITH STRONGER LOW
LEVEL COLD ADVECTION/SUBSIDENCE IN ITS WAKE. CONTINUED THE DRY FCST
OVERNIGHT. HIGH PRESSURE FROM THE NORTHERN/WESTERN PLAINS BUILDS
INTO THE AREA FOR WED THRU THU NIGHT. DRIER AIR FILTERS INTO THE
AREA WED...WITH DEW POINTS EXPECTED TO FALL INTO THE 50S BY LATER IN
THE AFTERNOON. TIGHTER PRESSURE GRADIENT OVER THE AREA ON WED. MODEL
SOUNDINGS INDICATE MIXING TO 875-850MB WED AFTERNOON...WITH 850MB
WINDS IN THE 30KT RANGE. ADDED SOME WINDS GUSTS UP TO 25-30MPH FOR
WED AFTERNOON. GRADIENT SLOW TO RELAX WED NIGHT...WITH SOME LIGHTER
NORTHWEST WINDS EXPECTED TO PERSIST INTO THU MORNING. AT ONE POINT
CONCERNED WITH VALLEY FOG FOR LATE WED NIGHT/EARLY THU MORNING BUT
NORTHWEST WINDS THRU WED NIGHT NOW EXPECTED TO KEEP THIS TO A
MINIMUM. LOWER LEVEL WARM ADVECTION/ ISENTROPIC LIFT...MOISTURE
TRANSPORT/THETA-E CONVERGENCE AHEAD OF THE NEXT TROUGH/FRONT ALREADY
SPREAD INTO THE AREA FRI...ALONG WITH MU CAPE VALUES OF 500-1500
J/KG BY FRI AFTERNOON. WITH THE MAIN SHORTWAVE PASSING WELL NORTH OF
THE AREA...FORCING/LIFT LOOK TO REMAIN WEAK AND LIMITED TO THE LOWER
LEVELS...LEFT SHRA/TSRA CHANCE CENTERED ON FRI AFTERNOON/EVENING IN
THE 20-25 PERCENT RANGE.

GENERALLY FAVORED A BLEND OF GUIDANCE LOWS/HIGHS FOR TONIGHT THRU
FRI NIGHT. WITH PLENTY OF SUNSHINE EXPECTED WED/THU AND THE DRIER
AIRMASS...DID TREND TOWARD WARMER OF GUIDANCE HIGHS BOTH DAYS.

.LONG TERM...SATURDAY THROUGH TUESDAY

23.12Z MEDIUM RANGE MODELS IN REASONABLE AGREEMENT SAT/SUN...AT
LEAST AT 500MB AND WITH NON-IRENE ELEMENTS. MODELS HAVE TRENDED BACK
TO A BIT FASTER WITH THE NEXT TROUGH TO DROP INTO THE REGION BY LATE
SUN. FOR MON/TUE MODELS ARE PROGRESSIVE WITH THE TROUGH SWINGING
THRU THE GREAT LAKES MON THEN SHORTWAVE RIDGING BUILDING IN FOR TUE.
OVERALL TREND LOOKS MORE PROGRESSIVE WITH /IRENE/ UP THE EAST COAST
IN THE SAT-MON PERIOD. WITH REASONABLY GOOD BETWEEN MODEL AND RUN-
TO-RUN CONSISTENCY...LONG TERM FCST CONFIDENCE AVERAGE TO GOOD THIS
CYCLE. STILL PLENTY OF DIFFERENCES IN THE LOWER LEVEL DETAILS WHICH
ADD SOME UNCERTAINTY TO THE DAY 4-7 FCST. MID LEVEL TROUGH AXIS/COLD
FRONT FROM FRI NIGHT SHOULD BE EAST/SOUTH OF THE AREA BY SAT
MORNING...WITH CAN HIGH PRESSURE BUILDING INTO THE UPPER MIDWEST FOR
THE WEEKEND. SAT SHOULD BE DRY AS SHOULD SAT NIGHT BUT FORCED TO
LEAVE A SMALL SHRA/TSRA CHANCE SAT NIGHT FOR COLLABORATION. BIT
FASTER TREND OF 23.12Z MODELS HAS NEXT FRONT/SFC TROUGH APPROACHING
THE WEST END OF THE FCST AREA BY LATER SUN. SMALL CONSENSUS
SHRA/TSRA CHANCE AT LEAST BY LATER SUN LOOKS REASONABLE. THIS
TROUGH/FRONT AND MID LEVEL TROUGH AXIS SLIDE ACROSS THE AREA SUN
NIGHT INTO MON WITH SHRA/TSRA CHANCES. SHORTWAVE RIDGING AND HIGH
PRESSURE RETURN FOR TUE. FAVORED A BLEND OF THE NUMERICAL TEMP
GUIDANCE FOR HIGHS/LOWS SAT THRU TUE...WITH TEMPS NEAR NORMAL FOR
THE WEEKEND AN A BIT BELOW NORMAL MON/TUE.

&&

.AVIATION...TONIGHT AND WEDNESDAY

CURRENTLY MONITORING A MID-LEVEL SHORTWAVE TROUGH PUSHING ACROSS THE
AREA THIS AFTERNOON. INSTABILITY UNDER THIS TROUGH WITH HEATING OF
THE DAY HAS LED TO SCATTERED SHRA/TS ACTIVITY EAST OF THE MS RIVER.
AS SUCH...HAVE INCLUDED VCSH WITH SCT035CB IN THE KLSE TAF TIL 7 PM
TONIGHT. CLEARING EXPECTED TO TAKE PLACE TONIGHT WITH SCATTERED
ALTOCUMULUS WITH BASES AOA 7KFT. MEANWHILE...WEST OF THE RIVER AT
KRST...SOME LOWER CU/STRATOCUMULUS WITH BASES 2500FT IS EXPECTED TO
CONTINUE INTO THIS AFTERNOON...THEN DISSIPATE/CLEAR BY 23Z. VFR
CONDITIONS EXPECTED TONIGHT. A SURFACE COLD FRONT WILL THEN PUSH
THROUGH THE REGION BY EARLY MORNING...SWITCHING THE WINDS TO THE
NORTHWEST. DAYTIME MIXING IS EXPECTED TO LEAD TO SOME GUSTY
NORTHWEST WINDS ON WEDNESDAY.
