AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
600 PM CDT WED JUN 27 2012

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT
319 PM CDT WED JUN 27 2012

MAIN FORECAST CONCERN CONTINUES TO BE FOCUSED ON HEAT THROUGH
THURSDAY...ALONG WITH LOW-END RAIN CHANCES TONIGHT THROUGH SATURDAY.

LARGE SCALE WATER VAPOR IMAGERY/RAP ANALYSIS HAS A FAIRLY AMPLIFIED
RIDGE OF HIGH PRESSURE OVER THE MID-SECTION OF THE CONUS/UPPER
MISSISSIPPI RIVER VALLEY REGION. A PLUME OF SUBTROPICAL MOISTURE WAS
ALSO SEEN EXTEND AROUND THE BACKSIDE OF THE RIDGE FROM THE BAJA INTO
THE DAKOTAS/WESTERN MN. AT THE SURFACE...A COLD FRONT EXTENDED FROM
WESTERN MN INTO CENTRAL NEB. WARM AIR ADVECTION AHEAD OF THE FRONT
AND COMPRESSIONAL HEATING UNDER THE RIDGE WAS PRODUCING VERY WARM
TEMPERATURES ACROSS THE AREA AT 3 PM RANGED FROM 84 DEGREES AT
MEDFORD WI...TO AS HIGH AS 95 DEGREES AT BOSCOBEL WI. HEAT INDICES
RANGED FROM 95 TO 105 DEGREES ALONG AND WEST OF THE MISSISSIPPI
RIVER. AS A RESULT...WILL LEAVE HEAT ADVISORY AS IS ACROSS THIS
AREA...WHICH WILL EXPIRE AT 8 PM THIS EVENING.

FOR THE REMAINDER OF THE NIGHT...WILL BE WATCHING THE COLD FRONT
OVER WESTERN MN MOVE EAST...EXTENDING FROM NORTHEAST WI THROUGH
SOUTHWEST WI/NORTHEAST IA BY 12Z. A BAND OF ELEVATED
CONVECTION/ACCAS IS EXPECTED TO ACCOMPANY THE FRONT AS MOISTURE
POOLS ALONG THE FRONT. BUFKIT SHOWS THE BASE OF THIS CLOUD TO BE
ABOVE 12KFT WITH A RATHER STOUT CAP REMAINING IN PLACE AROUND 800MB.
CURRENT THINKING IS THAT THIS SHRA ACTIVITY WILL REMAIN IN VIRGA
FORM...EVAPORATING BEFORE REACHING THE GROUND. NONETHELESS A FEW
MEASURABLE SHRA COULD REACH THE GROUND. WILL GO WITH A SLIGHT CHANCE
OF SHRA/TS THEN AFTER MIDNIGHT TO COVER THIS SCENARIO.
OTHERWISE...LOOK FOR TEMPERATURES TO ONLY COOL INTO THE 70S.

FOR THURSDAY...APPEARS THE COLD FRONT WILL CONTINUE PUSHING SOUTH
AND EAST INTO SOUTHERN WI/NORTHEAST WI BY AFTERNOON. NAM 0-1KM
MLCAPE PUSHING INTO THE 3500-5000J/KG RANGE AHEAD OF THE FRONT WITH
AROUND 30KT OF 0-3KM BULK SHEAR. AT THE SAME TIME...BUFKIT SHOWING A
FAIRLY STRONG CAP IN PLACE. IF THE CAP CAN BE WEAKENED...WILL HAVE
TO WATCH CLOSELY FOR THE POTENTIAL OF SEVERE WEATHER ACROSS SOUTHERN
WI/NORTHEAST IA WITH LARGE HAIL AND DAMAGING WIND BEING THE MAIN
THREATS. OTHERWISE...VERY WARM AND STICKY CONDITIONS WILL BE SEEN
AHEAD OF THE FRONT ACROSS SOUTHERN WI WITH TEMPERATURES EXPECTED TO
TOP OFF IN THE LOW-MID 90S WITH DEW POINTS AROUND 70. THIS IS
EXPECTED TO YIELD HEAT INDICES IN THE 100-105 DEGREE RANGE SOUTH OF
A LINE FROM MAUSTON WI THROUGH PRAIRIE DU CHIEN. SINCE THERE IS
ALREADY A HEAT ADVISORY HEADLINE OUT FOR PORTIONS OF THE AREA TIL 8
PM THIS EVENING...WILL LET THAT HEADLINE EXPIRE AND ASSESS WHAT AREA
NEEDS TO BE IN AN ADVISORY FOR THURSDAY. PRELIMINARY INDICATIONS ARE
THAT RICHLAND/CRAWFORD/GRANT COUNTIES WILL NEED AN ADVISORY. WILL
CONTINUE TO ASSESS THIS EVENING AND HAVE NEW HEADLINE OUT BY 10 PM
NEWS TIME.

APPEARS THAT THIS FRONTAL BOUNDARY WILL REMAIN QUASI-STATIONARY
THROUGH SATURDAY NIGHT AS FLOW ALOFT BECOMES PARALLEL TO IT. A
COUPLE MID-LEVEL TROUGHS ARE EXPECTED TO INTERACT WITH THIS BOUNDARY
FOR PERIODIC SHRA/TS CHANCES. LOOK FOR HIGHS ON FRIDAY IN THE UPPER
80S TO LOWER 90S AND IN THE MID 80S/FEW LOWER 90S ON SATURDAY.

.LONG TERM...SUNDAY THROUGH WEDNESDAY
319 PM CDT WED JUN 27 2012

LATEST ECMWF/GFS SHOW A BUILDING RIDGE OVER THE AREA THROUGH THE
PERIOD. SEVERAL WEAK MID-LEVEL TROUGH ROTATE OVER THE RIDGE SUNDAY
THROUGH TUESDAY FOR A CHANCE OF SHOWERS AND THUNDERSTORMS. BY
WEDNESDAY...MODELS SHOW THE RIDGE AMPLIFYING ACROSS THE PLAINS INTO
THE UPPER MISSISSIPPI RIVER FOR DRY CONDITIONS. LOOKS LIKE HIGHS
THROUGH THE PERIOD WILL CONTINUE TO BE ABOVE NORMAL WITH HIGHS
TOPPING OFF IN THE MIDDLE 80S TO LOWER 90S.

&&

.AVIATION...
600 PM CDT WED JUN 27 2012

COLD FRONT WILL SHIFT SOUTHEAST ACROSS THE REGION TONIGHT AND
TOMORROW...LIKELY MOVING THROUGH KRST NEAR 08-09Z AND KLSE 10-11Z.
MOISTURE POOLING AROUND THE BOUNDARY COULD RESULT IN SOME SUB VFR
CIGS...WHICH SOME MODELS ARE SUGGESTING. SOME 2500-3000 CLOUDS NEAR
THE BOUNDARY EVIDENCED BY LATEST SATELLITE IMAGERY AND SFC OBS...BUT
TRENDS ARE DIMINISHING THIS AREA. WILL OPT TO STAY WITH SOME SCT035
TO ACCOUNT FOR THIS POTENTIAL. HIGHER MID LEVEL CLOUDS MORE LIKELY
OVERNIGHT THROUGH THU MORNING. ALSO...THE HRRR POINTS TO SOME -SHRA
POSSIBILITIES AS THE FRONT MOVES THROUGH THE TAF SITES. CHANCES ARE
TOO SMALL TO INCLUDE IN THE TAFS AT THIS TIME.
