NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 14, 10:15 PM CST, 5 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 1115 PM CDT THU JUN 14 2012 .SHORT TERM...TONIGHT THROUGH SUNDAY 242 PM CDT THU JUN 14 2012 MAIN FORECAST CONCERNS ARE ON SEVERE THUNDERSTORM CHANCES LATE THIS AFTERNOON INTO THIS EVENING ACROSS PORTIONS OF NORTHEAST IOWA...SOUTHEAST MINNESOTA...WEST CENTRAL INTO NORTH CENTRAL WISCONSIN. FOCUS THEN TURNS TO SHOWER/THUNDERSTORM CHANCES TONIGHT THROUGH FRIDAY NIGHT. WATER VAPOR IMAGERY SHOWED A POTENT UPPER LEVEL TROUGH EXTENDING FROM CENTRAL MANITOBA SOUTH THROUGH WESTERN NORTH DAKOTA INTO NORTHEAST SOUTH DAKOTA...PUSHING EAST. SURFACE OBSERVATIONS SHOWED LOW PRESSURE MOVING INTO CENTRAL MINNESOTA. A WARM FRONT WAS DRAPED ACROSS CENTRAL MINNESOTA INTO SOUTHEAST MINNESOTA. A COLD FRONT EXTENDED SOUTHWEST FROM THE LOW THROUGH SOUTHWEST MINNESOTA...FAR NORTHWEST IOWA...THROUGH CENTRAL NEBRASKA. LATEST RADAR SHOWED THUNDERSTORM ONGOING ACROSS CENTRAL INTO SOUTH CENTRAL MINNESOTA...SOME OF WHICH HAVE BEEN SEVERE THIS AFTERNOON. PLAN ON ADDITIONAL SHOWERS AND THUNDERSTORMS DEVELOP ALONG THE FRONT LATE THIS AFTERNOON INTO THIS EVENING...IMPACTING THE FORECAST...PARTICULARLY ACROSS PARTS OF NORTHEAST IOWA...NORTHEAST IOWA...INTO WEST CENTRAL WISCONSIN. THE AFOREMENTIONED UPPER LEVEL TROUGH WILL MOVE NORTHEAST TONIGHT AND HEAD FOR HUDSON BAY. THE FRONT WILL DRAG THE COLD FRONT EASTWARD TONIGHT. THE FRONT WILL SLOW AND BECOME STATIONARY LATE TONIGHT INTO FRIDAY. FORECAST MODELS ARE SHOWING SOME SLIGHT DIFFERENCES ON EXACTLY WHERE THE STATIONARY BOUNDARY WILL ESTABLISH ITSELF ON FRIDAY. THE 12Z NAM PLACES THE FRONT STRETCHING FROM NORTH CENTRAL IOWA...NORTHEAST TO NEAR WINONA MINNESOTA INTO NORTHEAST WISCONSIN. THE 00 ECMWF SHOWS THE FRONT FURTHER TO THE NORTH...STRETCHING FROM SOUTH CENTRAL MINNESOTA INTO NORTH CENTRAL WISCONSIN. THE 12Z GFS IS IN LINE WITH THE NAM. AFTER SOME EARLY MORNING SHOWERS/THUNDERSTORMS ACROSS THE AREA...CAPE VALUES ARE EXPECTED TO INCREASE ALONG THE BOUNDARY. AFTERNOON 0-3 KM MUCAPE VALUES ARE EXPECTED TO RANGE FROM 1500 TO 2000 J/KG BY MID AFTERNOON. THE NAM DEWPOINTS LOOK A LITTLE ON THE HIGH SIDE FRIDAY AFTERNOON WITH VALUES RANGING FROM 68 TO 75...SO NOT BUYING INTO THE LARGE CAPE VALUES IT PRODUCING DURING THE AFTERNOON HOURS. NOT MUCH FORCING NOTED ALOFT BUT THE STRONG INSTABILITY AND WEAK CONVERGENCE ALONG THE FRONT SHOULD BE ENOUGH TO GET THUNDERSTORMS TO INITIATE AGAIN FRIDAY AFTERNOON. SHEAR IS RATHER WEAK...WITH 0-6 KM BULK SHEAR OF AROUND 20 KTS. CANNOT RULE OUT A PULSE SEVERE STORM OR TWO CAPABLE OF PRODUCING BRIEF HEAVY RAIN...AND POSSIBLY LARGE HAIL. THE NON SUPERCELL TORNADO PARAMETER INCREASES ALONG THE BOUNDARY...1.21...DURING THE AFTERNOON HOURS...SO WILL HAVE TO KEEP A CLOSE EYE ON ANY STORMS THAT DEVELOP NEAR THE BOUNDARY. DECIDED TO INCREASE SHOWERS/THUNDERSTORM CHANCES SLIGHTLY AND SHIFT THOSE HIGHER CHANCES A LITTLE FURTHER SOUTH VS. THE PREVIOUS FORECAST. THE EARLY MORNING THUNDERSTORMS AND CLOUD COVER/ALONG WITH THE LACK OF STRONG UPPER LEVEL SUPPORT WILL LIMIT OVERALL ORGANIZATION OF THE STORMS FRIDAY AFTERNOON. LOOK FOR THE SHOWERS/THUNDERSTORMS TO DISSIPATE EARLY FRIDAY EVENING AS SURFACE HEATING DIMINISHES. 850 MOISTURE TRANSPORT IS WEAK THROUGH THE DAY ALONG THE BOUNDARY...THIS SHOULD HELP TO MITIGATE THE HEAVY RAIN POTENTIAL. ACTIVE SOUTHWEST FLOW ALOFT WILL BE IN PLACE ACROSS THE FORECAST AREA FRIDAY NIGHT THROUGH SATURDAY. THE MAIN FEATURE TO KEEP A CLOSE WATCH ON WILL BE A VIGOROUS UPPER TROUGH PUSHING THROUGH THE DAKOTAS/CENTRAL PLAINS...MOVING EAST HEADED FOR THE UPPER MISSISSIPPI RIVER VALLEY. THE STATIONARY FRONT IS EXPECTED TO LIFT NORTH AND ACT AS A WARM FRONT AS THIS FEATURE DRAWS CLOSER. A LEADING SHORTWAVE WILL EJECT OUT OF THE CENTRAL PLAINS LATE FRIDAY NIGHT AND MOVE INTO THE FORECAST AREA EARLY SATURDAY MORNING. THIS FEATURE LOOKS TO SPARK A FEW SHOWERS AND THUNDERSTORMS AS IT MOVES INTO THE AREA EARLY SATURDAY MORNING. THE MAIN TROUGH FROM THE DAKOTAS...WILL BE PUSHING INTO MINNESOTA AS THE LEADING SHORTWAVE MOVES IN. THERE IS SOME DIFFERENCES IN THE MODELS REGARDING TIMING OF THIS WAVE. THE LEADING WAVE APPEARS TO MERGE WITH THE UPPER TROUGH AS IT PUSHES INTO THE FORECAST AREA LATE SATURDAY MORNING INTO SATURDAY AFTERNOON. CAPE AND SHEAR RAPIDLY INCREASES ACROSS THE FORECAST AREA SATURDAY LATE SATURDAY MORNING INTO SATURDAY AFTERNOON. THE STRONGEST 0-6KM SHEAR LAGS SLIGHTLY BEHIND THE FRONT. SHEAR APPEARS FAVORABLE FOR STRONG TO SEVERE THUNDERSTORMS WITH 0-6 KM BULK SHEAR VALUES OF 30 TO 40 KTS. THE WARM FRONT IS EXPECTED TO LIFT NORTH INTO UPPER MICHIGAN BY MID SUNDAY MORNING WITH WARM AND MOIST SOUTHERLY FLOW IN PLACE ACROSS THE FORECAST AREA. 0-3KM MUCAPE VALUES WILL INCREASE INTO THE 1500 TO 2500 J/KG RANGE BY SATURDAY AFTERNOON. THE TROUGH WILL PUSH A COLD FRONT FROM WEST TO EAST ACROSS THE FORECAST AREA..WITH SHOWERS AND THUNDERSTORMS EXPECTED ALONG THE FRONT. THE MAIN THREATS FROM ANY THUNDERSTORMS SATURDAY AFTERNOON WILL BE LARGE HAIL AND DAMAGING WINDS. WILL HAVE TO KEEP A CLOSE WATCH ON WHERE THE WARM FRONT ENDS UP. PLAN ON HIGHS ON SATURDAY RANGING FROM THE UPPER 80S ACROSS FAR SOUTHWEST WISCONSIN TO THE UPPER 70S TO AROUND 80 ACROSS NORTH CENTRAL WISCONSIN. HOWEVER...THESE TEMPERATURES WILL BE HIGHLY DEPENDENT ON CLOUD COVER STREAMING IN FROM THE WEST AHEAD OF THE APPROACHING TROUGH. WEAK HIGH PRESSURE WILL BUILD INTO THE AREA LATE SATURDAY NIGHT INTO EARLY SUNDAY MORNING...WITH A BRIEF DRY PERIOD EXPECTED DURING THE DAY ON SUNDAY. PLAN ON PARTLY TO MOSTLY SUNNY SKIES ON SATURDAY WITH HIGHS RANGING FROM THE LOWER 80S ACROSS NORTHEAST IOWA TO THE UPPER 70S ACROSS NORTH CENTRAL WISCONSIN. .LONG TERM...SUNDAY NIGHT THROUGH THURSDAY 242 PM CDT THU JUN 14 2012 14.12 MEDIUM RANGE MODELS IN REASONABLE AGREEMENT SUNDAY NIGHT INTO MONDAY...INDICATING ANOTHER TROUGH MOVING ACROSS THE DAKOTAS/MINNESOTA PUSHING EAST INTO THE UPPER MISSISSIPPI RIVER VALLEY DURING THE DAY ON MONDAY. A MORE FAVORABLE PATTERN FOR STRONG TO SEVERE THUNDERSTORMS LOOKS TO SET UP MONDAY INTO TUESDAY AS A WARM FRONT PUSHES BACK INTO THE REGION AND SOUTHWEST FLOW ALOFT REESTABLISHES ACROSS THE AREA. THE FIRST ROUND OF SHOWERS AND STORMS APPEARS TO MOVE THROUGH SUNDAY NIGHT INTO MONDAY MORNING...MAINLY NORTH OF INTERSTATE 90 AS THE FIRST IN A SERIES OF UPPER LEVEL TROUGHS MOVE THROUGH THE AREA. A FRONTAL BOUNDARY PUSHES ACROSS THE FORECAST AREA DURING THE DAY ON MONDAY...POTENTIALLY SPARKING ADDITIONAL SHOWERS AND STORMS SOUTH OF INTERSTATE 90 MONDAY AFTERNOON. THE FRONT THEN STALLS JUST SOUTH OF THE I-90 CORRIDOR AND STARTS TO DRIFT NORTH ON TUESDAY AS A VIGOROUS TROUGH DIVES INTO THE PACIFIC NORTHWEST AND MOVES EAST TOWARDS THE NORTHERN PLAINS. PLENTY OF MOISTURE AND SHEAR TO WORK WITH DURING THIS TIMEFRAME BUT ITS DIFFICULT TO PINPOINT EXACT TIMING DETAILS THIS FAR OUT. THE ACTIVE PATTER REMAINS OVER THE REGION INTO THURSDAY AS THE TROUGH MOVES EAST TOWARDS THE GREAT LAKES. HIGH TEMPERATURES ON MONDAY WILL CLIMB WELL INTO THE 80S...WITH SOME LOCATIONS POSSIBLY APPROACHING 90 IN NORTHEAST IOWA INTO FAR SOUTHWEST WISCONSIN. PLAN ON HIGHS IN THE 80S TUESDAY INTO WEDNESDAY. WITH A SLIGHT COOL DOWN POSSIBLE ON THURSDAY IN THE WAKE OF THE TROUGH EXPECTED TO MOVE THROUGH. && .AVIATION... 1115 PM CDT THU JUN 14 2012 MIXED SIGNALS IN THE MESO MODELS OVERNIGHT AS SOME SUGGEST THE CURRENT SHRA/TS WILL PERSIST OVERNIGHT...WHILE OTHERS POINT TO A DIMINISHING/ENDING TREND. PCPN IS FIRING IN THE VICINITY OF A FRONTAL BOUNDARY OVERNIGHT...AS LOW LEVEL MOISTURE TRANSPORT/INSTABILITY CONTINUES TO FEED IT. AS THE INSTABILITY WEAKENS EXPECT SOME DECREASE IN INTENSITY AND AREAL EXTENT...BUT WITH THE BOUNDARY IN PLACE AND A PERSISTENT STREAM OF LOW LEVEL MOISTURE...SCATTERED -SHRA/TS SEEMS MORE PROBABLE. BETTER CHANCES WOULD BE AT KRST WHICH IS CLOSER TO THE BOUNDARY. WILL LIKELY STICK WITH VCSH UNLESS TRENDS SHOW DEFINITE PERIODS OF -SHRA/TS. THE COLD FRONT LOOKS TO WAVER NORTHEAST-SOUTHWEST ACROSS THE REGION ON FRIDAY...AND WILL LIKELY SERVE AS THE FOCUS FOR MORE SHRA/TS. GREATER INSTABILITY IN THE AFTERNOON/EARLY EVENING WOULD FAVOR THIS TIME FRAME FOR CONVECTION. CONFIDENCE NOT TOO HIGH ON TIMING THOUGH. EXPECT THAT TAFS WILL NEED AMENDMENTS WHEN TIMING FOR PCPN THREATS BECOMES MORE CLEAR. OVERALL...VFR CONDITIONS ARE EXPECTED OUTSIDE OF THE ANY THUNDERSTORM THAT WOULD IMPACT KRST/KLSE. && .ARX WATCHES/WARNINGS/ADVISORIES... 242 PM CDT THU JUN 14 2012 WI...NONE. MN...NONE.
