AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
958 PM CDT THU AUG 1 2013

.UPDATE...
ISSUED AT 958 PM CDT THU AUG 1 2013

CONVECTION CONTINUES ON THE WARM FRONT WHICH IS NOW LOCATED ALONG
THE MISS RIVER. VERY NICE MOISTURE SURGE BEHIND THIS IN THE LOW-
LEVELS AND THIS MOISTURE ADVECTION HAS BEEN ACTIVE ALL NIGHT AND
IT WILL CONTINUE EAST. COLD FRONT IS LOCATED AND WEAKLY CONVERGENT
FROM ROUGHLY DULUTH TO SIOUX FALLS. OVERALL CONVECTION HAS
WEAKENED AND SEVERE WORDING PULLED FROM THE FORECAST PRODUCTS.

CONCENTRATED THE SCATTERED SHRA AND ISOLATED THUNDER CHANCES
EASTWARD FOR NEXT SEVERAL HOURS /WI/. THEN...THE COLD FRONT MOVES
IN FROM THE NORTH WITH SOME GREAT DRY AIR ADVECTION SCOURING THE
CAPE SOUTH. SO...THERE ARE ISOLATED SHRA/TS CHANCES WITH THE FRONT
MOVING THROUGH AFTER THE WARM FRONTAL MOISTURE CONVERGENCE CHANCES
SHIFT EAST. THEN...BY ABOUT SUNRISE...WE HAVE A FRONT MOVING
SOUTHWARD AND ALMOST OUT OF THE AREA. THINKING THAT FRIDAY WILL BE
DRY ALL AREAS BUT THE VERY SOUTH. DRY CONDITIONS MOVE IN FROM
FRIDAY AFTERNOON TO SUNDAY. WILL HAVE THE NIGHT SHIFT ALTER FRIDAY
MORE...BUT TRENDS ARE IN THE FORECAST NOW.
&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 343 PM CDT THU AUG 1 2013

MAIN FORECAST CONCERNS THIS PACKAGE...SHRA/TSRA CHANCES TONIGHT/
FRI...TEMPERATURES.

DATA ANALYSIS AT 18Z HAD BROAD LOW PRESSURE OVER HUDSONS BAY AND A
RIDGE OF HIGH PRESSURE FORM MO TO SASKAT. A WEAK TROUGH WAS LOCATED
NEAR THE MN/DAKOTAS BORDER. IMPACTS OF THE HUDSON BAY LOW ON THE
REGION WERE MAINLY DIURNAL CUMULUS OVER THE NORTHEAST 2/3 OF MN/WI...
AND SUPPORTING THE A SEASONABLY COOL/DRY AIRMASS UNDER THE DEEP
NORTHWEST FLOW BEHIND THE LOW AND EAST OF THE RIDGE AXIS. AS OF EARLY
AFTERNOON CONVECTION REMAINED NEAR OR WEST OF THE SFC RIDGE AXIS...
OVER PORTIONS OF SD/NEB.

01.12Z MODELS LOOK TO HAVE INITIALIZED WELL...BUT FOR THE GFS WITH
ITS USUAL SFC DEW POINT ANALYSIS BEING OFF A BIT OVER THE UPPER
MIDWEST. DPROG/DT OF 500MB HGTS AT 01.12Z SHOWED THE MODEL RUNS OF
30.12Z AND 31.12Z VERIFIED WELL ACROSS NOAM/EASTERN PAC EVEN WITH THE
SMALLER SCALE FEATURES IN THE FLOW. SOLUTIONS VERY SIMILAR FOR
TONIGHT/FRI...CONVERGING TOWARD A TIGHTER/COMMON CONSENSUS. SOLUTIONS
THEN DIVERGE FOR THE 3RD PERIOD /FRI NIGHT/ WITH THE NAM AGAIN
STRONGER ON A SHORTWAVE DROPPING THRU THE NORTHWEST FLOW TOWARD THE
AREA AND IS MORE ROBUST WITH LIFT/MOISTURE OVER THE AREA. NO ONE
MODE WITH CLEARLY BETTER RUN-TO-RUN CONSISTENCY THAN THE OTHERS.
CHECK OF OBS VS. MODEL DATA AT 18Z SHOWED ALL MODELS WERE QUITE
REASONABLE WITH THE SFC MASS FIELDS OVER THE CENTRAL CONUS. GFS WAS
IMPROVING ON SFC DEW POINTS. PER WV IMAGERY MODELS ALL LOOKED TO
HAVE A GOOD HANDLE ON THE MORE IDENTIFIABLE SHORTWAVES IN THE FLOW
OVER NOAM. MODELS REASONABLE WITH THE 12-18Z PRECIP OVER THE CENTRAL/
NORTHERN PLAINS AND WITH THE SCT SHRA IN FAR NORTHEAST MN/WI.
FAVORED THE MODEL/ENSEMBLE CONSENSUS FOR TONIGHT/FRI. WITH THE
NAM AGAIN APPEARING AS AN OUTLIER FRI NIGHT FAVORED THE NON-NAM
MODEL CONSENSUS. SHORT TERM FCST CONFIDENCE GOOD TONIGHT/FRI THEN
AVERAGE FRI NIGHT.

FOR THE SHORT TERM...MODELS STILL SPREADING SOME 850-700MB MOISTURE
TRANSPORT/THETA-E CONVERGENCE ACROSS ABOUT THE SOUTHWEST THIRD OF
THE FCST AREA TONIGHT/FRI. THE FLOW IS MORE PARALLEL TO THE THERMAL
GRADIENTS THAN IS PERPENDICULAR TO IT...THUS THE OVERALL CONVERGENCE
AND LIFT OF THE AIRMASS STAYS ON THE WEAK SIDE. EVEN MU CAPE OVER
THE SOUTHWEST END OF THE FCST AREA REMAINS ON THE LOW SIDE TONIGHT.
THUS NOT SURE HOW MUCH TSRA THERE WILL BE TONIGHT. WITH THE
CONSISTENCY OF THE MODEL SIGNAL TO PRODUCE SOME PRECIP OVER THE
SOUTHWEST 1/3 OF THE FCST AREA...CONTINUED TO CARRY 20-50 PERCENT
SHRA/TSRA CHANCES OVER ABOUT THE SOUTHWEST 1/2 OF THE FCST AREA.
SOME OF THIS MOISTURE TRANSPORT AND WEAK LIFT CONTINUES TO TRANSLATE
ACROSS THE SOUTH END OF THE FCST AREA FRI...WITH MU CAPES AS HIGH AS
PERHAPS 1K-2K J/KG NEAR THE SOUTH BORDER OF THE FCST AREA FRI
AFTERNOON. CONTINUED MAINLY 20-40 PERCENT SHRA/TSRA CHANCES ACROSS
THE SOUTH 1/3 OF THE FCST AREA FOR FRI. FURTHER NORTH...WITH LESS
MOISTURE OR INCREASE OF MOISTURE AND MORE UNDER THE WEST EDGE OF
THE NORTHWEST FLOW AROUND THE HUDSON BAY LOW/VORTEX...TREND SKY
GRIDS MORE TOWARD CLEAR TO PARTLY CLOUDY TONIGHT/FRI.

BIGGER QUESTIONS ARE FRI NIGHT. AGAIN NAM BRINGS A STRONGER
NORTHWEST FLOW SHORTWAVE TOWARD THE AREA...WHICH HELPS TO GENERATE A
RATHER STRONG LOOKING 850-500MB FN CONVERGENCE BAND NORTHWEST TO
SOUTHEAST ACROSS THE AREA OVER THE AREA BY LATER FRI NIGHT. MUCH OF
THE MOISTURE THE NAM BRINGS LOOKS TO BE IN THE 800-600MB LAYER...
WITH LITTLE IN THE WAY OF INSTABILITY. APPEARS EVEN IF NAM WAS
CORRECT ANY PRECIP MAINLY LATER FRI NIGHT WOULD BE SPRINKLES/-RA
FROM AN 8K-10K FT DECK. NAM HAS SOME MOISTURE TRANSPORT AT 700MB
BUT THIS AGAIN NEARLY PARALLEL TO THE THERMAL GRADIENT. WITH NAM
LOOKING RATHER SUSPECT...LEFT FRI NIGHT DRY PER CONSENSUS OF OTHER
MODELS...WHICH BLENDS WELL WITH ALL NEIGHBORING GRIDS. WOULD EXPECT
AT LEAST SOME SCT/PERHAPS BKN MID CLOUD DECKS AND DID NOT ADD
VALLEY FOG TO THE LATE FRI NIGHT GRIDS FOR NOW.

USED A BLEND OF THE NUMERICAL GUIDANCE LOWS/HIGHS FOR TONIGHT THRU
FRI NIGHT.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 343 PM CDT THU AUG 1 2013

MAIN FORECAST CONCERNS FOR SAT THRU SUN NIGHT...TEMPERATURES SAT
THRU SUN...VALLEY FOG POTENTIAL CENTERED ON 12Z SUN...SHRA/TSRA
CHANCES SUN NIGHT.

MODELS REMAIN IN DECENT AGREEMENT SAT THRU SUN AS HGTS RISE A BIT
OVER THE WESTERN GREAT LAKES AND WEAK SHORTWAVE RIDGING ALOFT BUILDS
IN. BY SUN NIGHT MODELS A BIT AT ODDS WITH TIMING/STRENGTH OF A
SHORTWAVE TO LOWER HGTS AND DROP SOUTHEAST INTO THE UPPER MIDWEST.
GIVEN NO ONE MODEL WITH CLEARLY BETTER RUN-TO-RUN CONSISTENCY THAN
THE OTHERS...SIDED WITH THE MODEL/ENSEMBLE CONSENSUS. FCST
CONFIDENCE THIS PERIOD AVERAGE TO GOOD.

PROBLEMS WITH NAM ADDRESSED FOR FRI NIGHT EXTEND INTO SAT MORNING.
CONTINUED TO DISCOUNT NAM FOR SAT MORNING FOR SAME REASONS AND LEFT
SAT DRY AS HGTS RISE AND CAN HIGH PRESSURE NOSES SOUTHEAST INTO THE
WESTERN GREAT LAKES. LEFT SKIES FOR SAT GENERALLY MOSTLY SUNNY AS
WELL. 850MB TEMPS IN THE +9 TO +12C RANGE...STILL ABOUT 1 STANDARD
DEVIATION BELOW NORMAL. WITH PLENTIFUL SUNSHINE ON SAT...HIGHS
SHOULD CLIMB TO THE MID 70S-NEAR 80...EVEN WITH LIGHT NORTH WINDS
AND THE HIGH SLOWLY BUILDING IN. THE HIGH STILL SETTLES ACROSS
MN/IA/WI FOR SAT NIGHT. DEPENDING ON HOW DEW POINT DROP/DRYING
OCCURS ON SAT...AND RECOVERY IN THE EVENING...SAT NIGHT SHOWING
SIGNS FOR A FAVORABLE RADIATIONAL VALLEY FOG NIGHT. WILL ADD MENTION
OF AT LEAST PATCHY VALLEY FOG TO FCST GRIDS FOR A FEW HOURS
CENTERED ON 12Z SUN. LATEST MODEL SET HAVE ALL EITHER WEAKENED THE
SHORTWAVE DUE TO APPROACH SUNDAY OR DELAYED IT INTO SUN NIGHT...WITH
LITTLE IN THE WAY OF LOWER LEVEL MOISTURE TRANSPORT/INCREASE INTO
THE AREA UNTIL SUN NIGHT. THE DRY CAN HIGH PRESSURE IS NOW EXPECTED
TO HOLD OVER THE AREA THRU SUN. REMOVED THE SMALL SUN AFTERNOON
SHRA/TSRA CHANCES FROM THE WEST END OF THE FCST AREA. EVEN WITH A
WEAKER WAVE TO APPROACH SUN NIGHT...MODEL CONSENSUS CONTINUES WITH
AN INCREASE OF 850-700MB MOISTURE TRANSPORT/PW VALUES INTO THE AREA
SUN NIGHT...MORE SO AFTER MIDNIGHT. LEFT THE MODEL/ENSEMBLE CONSENSUS
ROUGHLY 30 PERCENT SHRA/TSRA CHANCE FOR SUN NIGHT BUT COULD PROBABLY
TRENDED MUCH OF THIS AFTER MIDNIGHT/EARLY MON MORNING.

USED A BLEND OF THE NUMERICAL GUIDANCE HIGHS/LOWS FOR SAT/SUN/SUN
NIGHT. CONTINUED TO TREND TOWARD COOLER OF GUIDANCE LOWS SAT NIGHT
WITH THE DRY/COOL CAN HIGH SETTLING OVERHEAD.

MEDIUM RANGE MODEL RUNS OF 01.12Z AND 01.00Z IN RATHER GOOD AGREEMENT
WITH EACH OTHER AND THEIR 31.00Z RUNS AT THE START OF THE DAY 4-7
PERIOD WITH A CONTINUATION OF THE BLOCKY WEST COAST PATTERN AND
DOWNSTREAM TROUGHING/NORTHWEST FLOW OVER CENTRAL/EASTERN NOAM.
DIFFERENCES SLOWLY EMERGE/GROW FOR TUE-THU WITH SLOW PROGRESSION EAST
OF THE WEST COAST BLOCK AND A SHARPER TROUGH/SHORTWAVE ROTATING
AROUND THE WEST SIDE OF THE EASTERN CAN VORTEX AND DROPPING INTO THE
WESTERN GREAT LAKES BY THU. EVEN WITH THE DIFFERENCES BY THU...FCST
CONFIDENCE REMAINS GOOD THAT TEMPS WILL REMAIN BELOW NORMAL THRU
THE DAY 4-7 PORTION OF THE FCST. THERE WILL BE SHRA/TSRA CHANCES NEXT
WEEK BUT THESE WILL BE DIFFICULT TO TIME DUE TO SHORTWAVE DETAIL
DIFFERENCES AMONG THE MODELS IN THIS TIME FRAME. THUS FCST CONFIDENCE
REMAINS BELOW AVERAGE CONCERNING MON-THU PRECIP CHANCES. FOR NOW
FAVORED THE MODEL/ENSEMBLE CONSENSUS THRU THE PERIOD.

AS THE SFC...THE MON-THU PERIOD LOOKS TO BE DOMINATED BY HIGH
PRESSURE WITH WEAK REFLECTIONS OF THE PASSING MID LEVEL SHORTWAVES.
THE STRONGER TROUGH/SHORTWAVE ROTATING AROUND THE WEST SIDE OF THE
EASTERN CAN VORTEX AND HEADED FOR THE REGION LOOKS TO DRIVE A
STRONGER COLD FRONT SOUTH ACROSS THE AREA TUE NIGHT/WED...WITH MORE
CAN HIGH PRESSURE TO BUILD IN BEHIND IT FOR LATER IN THE WEEK.
APPEARS MUCH OF THE MOISTURE FLUX INTO THE AREA WITH THE PASSING
SHORTWAVES WILL MAINLY BE ABOVE THE SFC...MORE IN THE 850-700MB
LAYER...AS HIGH PRESSURE CONTROLS THE AREA AND LIMITED CONNECTION
TO THE GULF OR SOUTHERN PLAINS MOISTURE. SFC DEW POINTS LOOKING TO
REMAIN IN THE MORE COMFORTABLE 50S TO PERHAPS MID 60S RANGE. THE
CONTINUED NORTHWEST FLOW WILL NOT HELP DEEP MOISTURE RETURN INTO
THE AREA EITHER. THIS WILL LIMIT THE MOISTURE THE PASSING WAVES AND
ROUNDS OF LOWER LEVEL THERMO-DYNAMIC FORCING WILL HAVE TO WORK WITH.
MODEL/ENSEMBLE CONSENSUS SHRA/TSRA CHANCES IN THE 20-30 PERCENT RANGE
MUCH OF THE DAY 4-7 PERIOD LIKELY DUE TO THIS...AND LOOK WELL TRENDED
UNTIL TIMING DETAILS BECOME CLEARER. UNDER THE NORTHWEST FLOW
ALOFT...THEN INCREASING INFLUENCE OF THE EASTERN CAN VORTEX LATE NEXT
WEEK...850MB TEMPS REMAIN AROUND 1 STANDARD DEVIATION BELOW NORMAL
EARLY IN THE WEEK...TRENDING TO 1 TO 2 BELOW NORMAL BY THU/FRI.
DECENT CONFIDENCE FOR MON-THU HIGHS/LOWS TO STAY SOME 1 TO 2
CATEGORIES BELOW NORMAL...EVEN COOLER LATER IN THE WEEK.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 1232 PM CDT THU AUG 1 2013

VFR CONDITIONS EXPECTED THROUGH THE FORECAST PERIOD AND THE MAIN
FOCUS IS ON INCREASING MOISTURE SURGE / UPPER LEVEL IMPULSE MOVING
ACROSS THE DAKOTAS INTO WESTERN MINNESOTA. THIS WEATHER SYSTEM IS
LIKELY TO GENERATE SHOWERS AND THUNDERSTORMS ACROSS THAT AREA...THEN
TRACK INTO SOUTHERN MINNESOTA AND IOWA THROUGH THE EVENING. THE
HIGHEST CHANCES LOOK TO REMAIN SOUTH/WEST OF THE TAF SITES...HOWEVER
WILL CONTINUE TO HONOR VCSH GROUP AT KRST FOR A FEW HOURS THIS
EVENING. BROKEN MID LEVEL DECK COULD LINGER THROUGH PARTS OF THE
OVERNIGHT...GIVING WAY TO MOSTLY CLEAR SKIES BY SUNRISE. FOR
FRIDAY...EXPECTING MOSTLY SUNNY SKIES AND LIGHT WEST/NORTHWEST WINDS
AS FRONTAL BOUNDARY REMAINS SOUTH IN IOWA AND HIGH PRESSURE BUILDS IN
FROM THE NORTH.
