AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
640 AM CDT MON AUG 26 2013

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 309 AM CDT MON AUG 26 2013

 ..CURRENTLY AS OF 08Z..
WATER VAPOR LOOP AND RAP 500MB HEIGHT ANALYSIS SHOWED TROUGHING OVER
THE PACIFIC NORTHWEST AND EASTERN PACIFIC...AND STRONG SUBTROPICAL
RIDGING OVER KANSAS AND MISSOURI. MONSOONAL MOISTURE AND SHORTWAVES
CONTINUES TO STREAM OUT OF BAJA CALIFORNIA...UP THROUGH THE DAKOTAS
AND INTO THE NORTHERN GREAT LAKES AROUND THE SUBTROPICAL RIDGE. ONE
SUCH SHORTWAVE COMBINED WITH 700MB MOISTURE TRANSPORT SUPPORTING
CONVECTION TRACKING ACROSS FAR NORTHERN WI AND UPPER MICHIGAN.
REGARDING MOISTURE...GOES DERIVED PRECIPITABLE WATER IMAGERY SHOWED
VALUES OF 1.5-2 INCHES FROM EASTERN SOUTH DAKOTA INTO THE NORTHERN
GREAT LAKES. AIRMASS IS ALSO VERY WARM WITH 850MB TEMPS FROM 00Z
RAOBS OF 22-24C ACROSS THE FORECAST AREA AND 24-28C OVER THE
NORTHERN PLAINS. WITH THE FORECAST AREA IN THE WARM SECTOR...SOUTH
OF A WARM FRONT POSITIONED OVER FAR NORTHERN WI...A SOUTHERLY BREEZE
HAS ONLY ALLOWED TEMPS TO FALL INTO THE MID TO UPPER 70S. THIS SAME
SOUTHERLY BREEZE HAS ADVECTED IN SOME LOWER DEWPOINTS...WHICH HAVE
FALLEN INTO THE 60S...LOWEST IN THE SOUTHEAST HALF OF THE AREA. 00Z
DVN SOUNDING REALLY SHOWED THE DRIER AIR COMPARED TO MPX.

 ..MODEL VERIFICATION..
HAVE INCLUDED THIS SECTION AS IT HAS HIGH IMPORTANCE WITH THE
FORECAST OF HIGH TEMPERATURES AND CONVECTION. LOOKING AT 00Z RAOBS
FOR 925MB TEMPS AND COMPARING TO 25.00Z MODEL GUIDANCE...THE ECMWF
WAS THE BEST WITH ALMOST NO ERROR ACROSS THE NORTHERN PLAINS AND
UPPER MIDWEST. THE GFS WAS GENERALLY 1-2C TOO HIGH. LASTLY...THE
NAM/RAP WERE THE WORST...HAVING ERRORS ON THE ORDER OF 3-6C...
HIGHEST AT MSP. BECAUSE THE NAM/RAP WERE TOO HIGH...IT BROKE THE CAP
AND BROUGHT THE CONVECTION WAY TOO FAR SOUTH.

 ..HAZARDS..
1. HEAT. TEMPERATURES ARE LIKELY TO BE A FEW DEGREES HIGHER TODAY
AND WITH DEWPOINTS CLIMBING BACK INTO THE LOW 70S...HEAT INDICES
SHOULD TOP OUT IN THE 100-105 RANGE. THE HIGHEST HEAT INDICES LOOK
TO OCCUR FROM LAKE CITY DOWN TO LA CROSSE...AND HAVE UPGRADED THIS
AREA TO AN EXCESSIVE HEAT WARNING.

2. STORMS. SOME SEVERE POTENTIAL AFTER MIDNIGHT TONIGHT...MAINLY
ACROSS TAYLOR/CLARK COUNTIES. HAVE TO WATCH RAINFALL AMOUNTS TOO.

 ..SYNOPTIC OVERVIEW..
26.00Z MODEL GUIDANCE SUGGESTS THE SUBTROPICAL RIDGING RETROGRADES
JUST SLIGHTLY WESTWARD DURING THE NEXT 24 HOURS. THE MAIN FEATURE OF
FOCUS IS A STRETCHED OUT SHORTWAVE IN THE MONSOONAL FLOW...LOCATED
FROM EASTERN UTAH INTO SOUTH CENTRAL WYOMING. MODELS BRING THIS
SHORTWAVE INTO THE DAKOTAS BY 00Z AND PERHAPS AS FAR EAST AS WESTERN
UPPER MI BY 12Z. THIS SHORTWAVE HELPS TO LIFT A SURFACE LOW SITTING
NEAR THE BLACK HILLS OF SOUTH DAKOTA TO NEAR MINNEAPOLIS BY 12Z TUE.

 ..DETAILS..
FOCUS FOR POTENTIAL CONVECTION TODAY WILL LIE ON THE LOCATION OF THE
WARM FRONT IN NORTHERN WI. FIRST OFF...THE CURRENT CONVECTION
CROSSING FAR NORTHERN WI AND UPPER MI COULD DROP INTO TAYLOR AND
POSSIBLY CLARK COUNTY BEFORE WEAKENING THIS MORNING. THE OUTFLOW
FROM THE CONVECTION SHOULD HELP PUSH THE FRONT SOUTH TOWARDS I-94
THIS AFTERNOON. THEN...THE NEXT QUESTION IS IF THE AIRMASS IS
CAPPED...WHICH ENTIRELY DEPENDS ON HOW WARM WE GET. THERE SHOULD BE
PLENTY OF SUN TODAY ACROSS THE FORECAST AREA WITH MAYBE A FEW STRAY
CIRRUS CLOUDS. ECMWF 925MB TEMPS ARE PROGGED ABOUT 1-2C HIGHER
COMPARED TO YESTERDAY...THUS ANTICIPATING HIGHS TO BE ABOUT 1-3F
HIGHER... YIELDING READINGS MAINLY IN THE LOW TO MID 90S. A FEW
SPOTS LIKE LSE COULD EVEN HIT THE UPPER 90S. ECMWF ALSO DID VERY
WELL WITH THE DEWPOINTS YESTERDAY AND SUGGESTS THEY SHOULD CLIMB
INTO THE LOW 70S IN THE AFTERNOON...DUE TO EVAPOTRANSPORATION AND
THE HIGHER MOISTURE TO OUR NORTHWEST SLIDING SOUTH. THE FORECAST
HIGHS AND DEWPOINTS WOULD SEEM TO POINT TO POTENTIAL FOR THE CAP TO
BREAK...THUS HAVE INCLUDED 20-40 PERCENT CHANCES ON THE WARM FRONT
FOR THE AFTERNOON. SHOULD STORMS DEVELOP...0-6KM SHEAR IS ONLY 25 KT
AT BEST WITH 0-3KM NEAR 20KT. THIS MEANS THE STORMS WILL PROBABLY BE
UNORGANIZED AND MOST LIKELY JUST HEAVY RAIN MAKERS GIVEN HIGH CAPE
AND NEAR 2 INCH PRECIPITABLE WATERS.

TONIGHT IS A BIT MORE INTERESTING. A CONVECTIVE COMPLEX APPEARS
LIKELY TO DEVELOP IN THE GRAND FORKS AREA IN THE EVENING AHEAD OF
THE SHORTWAVE. THIS CONVECTION...AIDED ALSO BY 700MB MOISTURE
TRANSPORT LIKE THE CONVECTION GOING OVER UPPER MI...SHOULD TRACK
EAST-SOUTHEAST INTO NORTHERN WI. THIS MEANS TAYLOR/CLARK COULD BE
IMPACTED BY THE COMPLEX AFTER MIDNIGHT. ADDITIONAL CONVECTION COULD
FORM ON THE NOSE OF 850MB MOISTURE TRANSPORT NORTH OF I-94 THIS
EVENING AS WELL. CANNOT RULE OUT SOME SEVERE WEATHER...LIKELY IN THE
FORM OF DAMAGING WINDS AND LARGE HAIL...ESPECIALLY AFTER MIDNIGHT
WHEN 0-6 KM SHEAR VALUES APPROACH 30-40 KT. THE REST OF THE AREA
SHOULD STAY MAINLY DRY...CAPPED AND WARM WITH A SOUTHERLY BREEZE
PERSISTING. LOW TEMPERATURES ARE LIKELY TO BE SIMILAR TO NOW GIVEN
SIMILAR CONDITIONS.

.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 309 AM CDT MON AUG 26 2013

 ..HAZARDS..
1. HEAT...WHICH WILL PERSIST INTO TUESDAY. COLD FRONT COMES THROUGH
TUESDAY NIGHT WHICH SHOULD HELP ADVECT BOTH SOMEWHAT COOLER AND MORE
IMPORTANTLY DRIER AIR INTO THE AREA FOR WEDNESDAY. HEAT LOOKS TO
RETURN DURING LABOR DAY WEEKEND.

2. STORMS. THOSE ON TUESDAY COULD POSE A SEVERE AND HEAVY RAIN
THREAT NORTH OF I-94.

 ..SYNOPTIC OVERVIEW..
26.00Z MODEL GUIDANCE CONTINUES TO SUGGEST THAT THE SUBTROPICAL HIGH
WILL RETROGRADE WESTWARD THROUGH THE WEEK...ENDING UP IN COLORADO ON
FRIDAY. THIS RETROGRESSION IS IN RESPONSE TO A SERIES OF SHORTWAVE
TROUGHS DROPPING INTO THE MID-ATLANTIC REGION ON THE EAST SIDE OF
THE RIDGE. AS WE HEAD INTO THE WEEKEND...THE SUBTROPICAL RIDGE WILL
SHIFT EAST IN RESPONSE TO WHAT LOOKS TO BE A VERY DEEP TROUGH FOR
THIS TIME OF YEAR COMING INTO THE PACIFIC NORTHWEST. IT SHOULD BE
NOTED THAT THE 26.00Z ECMWF THROWS A MAJOR CURVE BALL TO THE WEEKEND
PLAN...DEVIATING GREATLY FROM ITS PREVIOUS RUN IN SHOWING A TROUGH
DIGGING INTO THE WESTERN GREAT LAKES LATE SUNDAY. THE REASON IS
RELATED TO THIS TROUGH BEING STRONGER AND TRACKING FARTHER SOUTH
COMING OUT OF SOUTHWEST CANADA ON FRIDAY...COMPARED TO IT\S PREVIOUS
RUN...THE 26.00Z GFS AND CANADIAN. NOT READY TO FULLY BUY INTO THE
26.00Z ECMWF QUITE YET BEFORE SEEING THE ECMWF ENSEMBLES AND ITS
NEXT RUN.

 ..DETAILS..
THE SURFACE OVER CENTRAL MN AT 12Z TUESDAY WILL GRADUALLY DROP
SOUTHEAST THROUGH TUESDAY AND TUESDAY NIGHT...IN RESPONSE TO THE
SHORTWAVE AND CONVECTION OVER NORTHERN WI/UPPER MI DROPPING
SOUTHEAST. HAVE KEPT SOME CHANCES ON TUESDAY NORTHEAST OF I-94 FOR
THE CONVECTION DROPPING SOUTHEAST...WHICH COULD BE SEVERE AS WELL.
THE REST OF THE AREA LOOKS CAPPED. TALKING ABOUT THE CAPPING...925MB
TEMPS ARE PROGGED TO REACH ABOUT 28C ON I-94 TO 30C IN NORTHEAST
IOWA. THESE READINGS SHOULD YIELD HIGHS RANGING FROM THE LOW TO
UPPER 90S...WARMEST IN RIVER VALLEYS. THE EXCESSIVE HEAT WARNING MAY
NEED EXPANSION INTO SOME OF NORTHEAST IOWA AND FAR SOUTHWEST WI IF
TEMP/DEWPOINT TRENDS CONTINUE. ALL CONVECTION LOOKS LIKE IT WILL BE
SOUTHEAST OF THE AREA FOR TUESDAY NIGHT...THUS WENT DRY THEN.

DRY CONDITIONS ARE EXPECTED FOR WEDNESDAY AND WEDNESDAY NIGHT AS
HIGH PRESSURE BUILDS OVER WISCONSIN AND MICHIGAN IN THE WAKE OF
TUESDAY\S LOW AND COLD FRONTAL PASSAGE. 925MB TEMPS OF 24-26C STILL
SUPPORTS HIGHS IN THE MID 80S TO LOW 90S...THOUGH. DEWPOINTS MAY
STILL BE UP IN THE LOW 70S OVER NORTHEAST IOWA...BUT HEAT INDICES
ARE MORE AROUND 95 VERSUS THE 100-105 AS OF LATE.

THURSDAY THROUGH SATURDAY FEATURE A GRADUAL WARM ADVECTION
PATTERN...WHICH MEANS A RETURN FOR SOME CHANCES OF SHOWERS AND
THUNDERSTORMS. HIGHEST CHANCES ARE FORECAST THURSDAY NIGHT OVER
WISCONSIN WHERE THERE APPEARS TO BE A JUXTAPOSITION OF RIGHT
ENTRANCE REGION FORCING...A POSSIBLE SHORTWAVE MOVING THROUGH...AND
THE LOW LEVEL MOISTURE TRANSPORT. SOME OF THESE CHANCES OF SHOWERS
AND THUNDERSTORMS MAY BE ABLE TO BE BETTER REFINED...IN TERMS OF
DRYING SOME OUT...OVER THE COMING DAYS AS MODELS SETTLE INTO THE
TIMING OF THE WARM ADVECTION. ONCE THE WARM AIR COMES IN...WE WILL
HAVE TO BE CONCERNED WITH HEAT ADVISORIES...AS EVEN THE NEW 26.00Z
ECMWF SHOWS 925MB TEMPS APPROACHING 30C OVER WESTERN PORTIONS OF THE
FORECAST AREA LATE FRIDAY.

SUNDAY AND THE REST OF LABOR DAY WEEKEND FORECAST IS NOW UP IN THE
AIR DUE TO THE NEW 26.00Z ECMWF. PREVIOUSLY AND IN AGREEMENT WITH
THE 26.00Z GFS IT APPEARED MUCH OF THE AREA WOULD BE IN THE WARM
SECTOR...WITH 925MB TEMPS OF 29-32C WHICH COULD ALLOW FOR HIGHS
AROUND 100. IF THE NEW ECMWF IS RIGHT...WE GET A MOSTLY DRY COLD
FRONTAL PASSAGE ON SUNDAY WITH HIGHS MORE IN THE MID TO UPPER 80S.
MONDAY ENDS UP MUCH MUCH COOLER WITH HIGHS MOSTLY IN THE 60S.
COMPARE THIS TO IT\S PREVIOUS 4 RUNS SHOWING 94-98 AT LA CROSSE FOR
MONDAY.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z TUESDAY MORNING)
ISSUED AT 640 AM CDT MON AUG 26 2013

EXPECT THE LOW LEVEL WIND SHEAR AT KLSE TO RAPIDLY DISSIPATE BY
26.14Z AS THE LOW LEVEL JET AND PRESSURE GRADIENT WEAKENS...AND
THE NOCTURNAL INVERSION DISSIPATES THROUGH DIURNAL MIXING.

FOR TODAY...EXPECT ONLY SCATTERED 15K FOOT CLOUDS. WINDS WILL GUST
FROM SOUTHWEST INTO THE 15 TO 25 KNOT RANGE.

AFTER 27.07Z...THERE IS CONCERN THAT LOW LEVEL WIND SHEAR WILL
DEVELOP AT KLSE AS THE WINDS DROP TO LESS THAN 10 KNOTS BELOW THE
NOCTURNAL INVERSION AND THE LOW LEVEL JET STRENGTHENS ALOFT. THE
GFS HAS THIS JET CLIMBING INTO THE 30 TO 35 KNOT RANGE. MEANWHILE
THE NAM/WRF HAS THIS JET STRENGTHENING INTO THE 40 TO 45 KNOT
RANGE. DUE TO THE UNCERTAINTY OF THE STRENGTH OF THIS JET...HELD
OFF MENTIONING IT.
