AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 342 AM CDT TUE JUN 19 2012 .SHORT TERM...TODAY THROUGH THURSDAY NIGHT 342 AM CDT TUE JUN 19 2012 THE MAIN FORECAST CONCERNS THIS PACKAGE...SHRA/TSRA AND SEVERE CHANCES TODAY THRU WED NIGHT...TEMPERATURES. DATA ANALYSIS AT 06Z HAD LOW PRESSURE LOCATED OVER WESTERN NEB WITH A WARM FRONT EAST ALONG THE NEB/SD MN/IA BORDER INTO SOUTHERN WI. LITTLE DIFFERENCE IN AIRMASS NEAR THE BOUNDARY BUT SOME COOLER/DRIER AIR HAD SETTLED INTO NORTHERN MN/WI. STRONGER OF WARM/MOISTURE ADVECTION CENTERED ON 850MB AHEAD OF THE LOW FUELING CONVECTION OVER EASTERN SD INTO WESTERN/CENTRAL MN. VAD WIND PROFILES FROM AREA RADARS INDICATE CONVERGENCE IN THE 850MB WIND FIELD OVER NORTHERN IA/SOUTHERN MN INTO SOUTHERN WI...BUT MOISTURE TRANSPORT WEAKER AND UNDER SOME WARMER 850-700MB TEMPS. CONVECTION ACROSS WI LIMITED TO SCT SHRA FROM NEAR KGRB TO SOUTH OF KEAU...CLOSER TO THE EDGE OF THE WARM 850-700MB TEMPS/CAPPING. NO BIG ERRORS NOTED WITH 19.00Z MODEL INITIALIZATIONS. HOWEVER GFS AGAIN SOME 2-7F TOO HIGH WITH SFC DEW POINTS ACROSS MUCH OF THE MID/UPPER MS VALLEY. SOLUTIONS WITH RATHER SIMILAR OUTCOMES FOR TODAY THRU THU NIGHT...THOUGH GFS REMAINS THE MOST ROBUST WITH PRECIP TOTALS ACROSS THE AREA THROUGH THE PERIOD. DPROG/DT OF 500MB HGTS AT 19.00Z SHOWED THE MODEL RUNS OF 17.00Z AND 18.00Z VERIFIED WELL ACROSS NOAM WITH CURRENT RUNS TRENDING TOWARD A TIGHTER COMPROMISE OF THE EARLIER RUNS. MODEL CONSENSUS LOOSENS THRU TONIGHT AS THE NORTHERN ROCKIES TROUGHING MOVES ACROSS THE NORTHERN PLAINS. NAM/GFS FASTER THAN UKMET/GEM/ECMWF...WITH AN OVERALL SLOWING TREND WITH THIS TROUGH. THE SLOWER TREND CONTINUES WED/WED NIGHT AS THE TROUGH MOVES INTO MN/WI WITH A BIT BETTER CONSENSUS AT 12Z THU THAN 12Z WED. THE SLOWER TREND HOLDS MORE TROUGHING OVER THE AREA THRU THU NIGHT WITH THE DEVELOPING MID LEVEL RIDGE AXIS SLOWER TO MOVE EAST INTO THE NORTHERN PLAINS. RUN-TO-RUN CONSISTENCY SIMILAR AMONG THE MODELS. CHECK OF OBS VS. MODEL DATA AT 06Z SHOWED ALL REASONABLE WITH THE LOW AND WARM FRONTAL POSITION. GFS REMAINED TOO HIGH WITH SFC DEWPOINTS ACROSS MUCH OF THE UPPER MIDWEST...AND WAS MUCH TOO WET/WIDESPREAD WITH 00-06Z CONVECTION ACROSS MN/IA/WI. PER WV IMAGERY ALL MODELS APPEAR REASONABLE WITH THE SHORTWAVE FEATURES ACROSS NOAM/EASTERN PAC. NO FAVORED MODEL EARLY THIS MORNING... OTHER THAN LEANING AWAY FROM THE OVERLY WET GFS. HOWEVER AFTER THIS MORNING...GFS MORE IN LINE WITH OTHER MODELS AT LEAST WITH PRECIP PLACEMENT/TIMING OF FEATURES ACROSS THE AREA. FAVORED A MODEL/ ENSEMBLE CONSENSUS FOR TODAY THRU THU NIGHT...WITH SHORT-TERM FCST CONFIDENCE AVERAGE TO GOOD THIS CYCLE. FOR THE SHORT TERM...DISTANCE SPEED TOOL...CORFIDI VECTORS AND PRESENT TRENDS OF CONVECTION ACROSS MN SHOWS IT WILL SKIRT THE NORTH END OF THE FCST AREA THIS MORNING...ALONG/NORTH OF A LAKE CITY MN AND HWY 10 ACROSS CENTRAL WI LINE. WARM FRONT PUSHES QUICKLY BACK NORTH THIS MORNING AS THE SFC LOW LIFTS INTO EASTERN SD. THIS SENDS THE BULK OF THE LOWER LEVEL THERMODYNAMIC FORCING/CONVERGENCE/LIFT NORTH OF THE FCST AREA RATHER QUICKLY. WILL LIMITS MOST OF SHRA/TSRA CHANCES ACROSS THE NORTH END OF THE FCST AREA TODAY TO THE 12-15Z TIME-FRAME. WARM 850-700MB TEMPS WILL BUILD NORTH AS WELL WITH ANOTHER VERY WARM TO HOT DAY WITH AFTERNOON HEAT INDICES IN THE 90- 100 RANGE UNDER THE CAPPING. GRADIENT TIGHTENS OVER THE AREA FOR BRISK SOUTH WINDS OF 15-25MPH AND GUSTY IN PLACES. WINDS SHOULD HELP OFFSET SOME OF THE HEAT AND WILL AGAIN HOLD OFF ON ANY HEAT ADVISORY FOR NOW. THE SFC LOW WILL LIFT ACROSS MN TONIGHT AS THE MID LEVEL TROUGH/ SHORTWAVE ENERGY MOVES INTO THE NORTHERN PLAINS. THE LOW DRAGS A COLD FRONT TO NEAR A KDLH-KFSD LINE BY 12Z WED. MODELS DO DIFFER ON THE PLACEMENT OF THE FRONT BY 12Z WED...BUT CONSENSUS IS SLOWER THAN THE PREVIOUS RUNS. INCREASING 925-850MB MOISTURE TRANSPORT/WARM ADVECTION THETA-E CONVERGENCE SPREAD ACROSS THE AREA LATER TONIGHT AHEAD OF THE FRONT. THIS UNDER COOLING 700-50MB TEMPS AS THE MID LEVEL TROUGH APPROACHES. CAP ERODES FOR LATER TONIGHT/WED...WITH AREA UNDER FAVORABLE RIGHT ENTRANCE REGION OF A 110+KT 300MB JET MAX...ESPECIALLY ON WED. THIS ALONG WITH MDT/STRONG SHOT OF SFC- 700MB FN CONVERGENCE WITH THE FRONT...PW VALUES OF 1.5 TO 2 INCHES...ML CAPES OF 1K-2K J/KG AND INCREASING 0-6KM SHEAR. SEVERE STORMS AND LOCALLY HEAVY RAINS POSSIBLE WED INTO WED EVENING AS THE FRONT SLOWLY PROGRESSES SOUTHEAST ACROSS THE AREA. SEE SWODY2 AND HYDROLOGY SECTION BELOW FOR MORE DETAILS. WITH THE SLOWER TIMING AND IMPROVING MODEL CONSISTENCY RAISED RAIN CHANCES TOWARD 70-80 PERCENT OVER THE NORTHWEST 2/3 OF THE FCST AREA WED AND SOUTHEAST 1/3 WED EVENING. ADDED MORE TEMPORAL RESOLUTION TO RAIN CHANCES ON WED. LINGERED MORE RAIN CHANCES OVER THE SOUTHEAST HALF OF THE FCST AREA LATE WED NIGHT. WEATHER TURNS RELATIVELY QUIET FOR THU/THU NIGHT AS DRIER/COOLER HIGHS PRESSURE FROM THE NORTHERN PLAINS BUILDS INTO THE MID/UPPER MS VALLEY. DEW POINTS LOOK TO FALL INTO THE 50S WITH HIGHS THU IN THE MID 70S TO NEAR 80...FOR A MORE COMFORTABLE DAY ON THU. WITH PLENTY OF SUNSHINE FOR THE LATE MORNING/AFTERNOON AND THE SOUTH WINDS FOR MIXING...FAVORED WARMER OF GUIDANCE HIGHS FOR TODAY. AFTER THAT...TRENDED TOWARD A BLEND OF THE GUIDANCE LOWS/HIGHS FOR TONIGHT THRU THU NIGHT. .LONG TERM...FRIDAY THROUGH MONDAY 342 AM CDT TUE JUN 19 2012 MEDIUM RANGE MODELS IN DECENT AGREEMENT FRI-MON WITH THE TROUGH MOVING EAST OF THE REGION FRI THEN RIDGING ALOFT TRYING TO BUILD EAST ACROSS THE CENTRAL CONUS SAT-MON. SHORTWAVES RIPPLING THRU AND OVER THE MODEST RIDGING FRI/SAT KEEP THE FLOW ALOFT OVER THE AREA NORTHWEST AND CYCLONIC. GOOD CONSISTENCY BETWEEN THE MODELS AND THEIR PREVIOUS RUNS FOR ONE OF THESE WAVES TO DEVELOP A LOW IN THE CENTRAL/NORTHERN PLAINS FRI/SAT. ACCOMPANYING ROUND OF LOWER LEVEL THERMODYNAMIC FORCING/LIFT AND MOISTURE TRANSPORT AHEAD OF THE SFC-700MB LOW/TROUGH SPREADS INTO THE AREA CENTERED ON SAT. SHRA/TSRA CHANCES IN THE 30-50 PERCENT RANGE CENTERED ON SAT LOOK WELL TRENDED AT THIS TIME. ONCE THIS WAVE PASSES FLOW ALOFT BECOMES NORTHWEST TO NORTH WITH A RATHER STRONG CAN HIGH PRESSURE SYSTEM BUILDING SOUTH INTO THE UPPER MIDWEST FOR SUN/MON. MODEL CONSENSUS FOR DRY WITH NEAR TO A BIT BELOW NORMAL TEMPS ON DAYS 6/7 ALSO LOOKS WELL TRENDED. && .AVIATION...THROUGH 06Z WEDNESDAY 1152 PM CDT MON JUN 18 2012 CONVECTION WAS DEVELOPING OVER EASTERN SOUTH DAKOTA AND SOUTHWEST MINNESOTA LATE THIS EVENING. THIS ON THE NOSE OF STRONG MOISTURE TRANSPORT. AS MOISTURE TRANSPORT INCREASES OVERNIGHT...CONVECTION WILL CONTINUE TO SPREAD EASTWARD OVER SOUTHERN MINNESOTA. THE 19.01Z HRRR CONTINUES TO SHOW THE MAIN THRUST OF THIS TO MOVE NORTH OF THE TAF SITES BETWEEN 06Z-12Z....BUT DID INCLUDE VCSH AT BOTH SITES. TRENDS WILL HAVE TO BE WATCHED FOR INCLUSION OF TSRA IF THE ACTIVITY IS FURTHER SOUTH. CEILINGS EXPECTED IN THE VFR CATEGORY. PRESSURE GRADIENT INCREASES LATER THIS MORNING AND FORECAST SOUNDINGS SHOWS POTENTIAL FOR GUSTS TO BETWEEN 25 AND 35 KNOTS...WITH THE HIGHER GUSTS AT KRST. WINDS LOOK TO STAY UP ABOVE 12 KNOTS ALL TE WAY THROUGH 06Z WEDNESDAY. && .HYDROLOGY...THIS MORNING AND AGAIN WED/WED EVENING 342 AM CDT TUE JUN 19 2012 A COUPLE MORE ROUNDS OF STORMS...TODAY AND AGAIN WEDNESDAY...WILL MAINTAIN AT LEAST THE POSSIBILITY FOR HEAVY RAINFALL AND POTENTIAL FLOODING CONCERNS. THE FIRST COMPLEX OF STORMS CURRENTLY TRAVERSING MN...AND HAS A BEAD FOR OUR NORTHERN FORECAST AREA. THIS IS ALSO THE AREA THAT GOT THE RAIN THE PAST FEW DAYS...SO IT BEARS WATCHING. AMPLE PRECIPITABLE WATER AND MOISTURE TRANSPORT UP AND OVER THE FRONTAL BOUNDARY TO GENERATE STORMS AS WE ARE SEEING...BUT THE POSITIVE IN THIS SO FAR IS THE PROGRESSIVE NATURE OF THE STORMS. FRONT IS ALSO SLOWLY TRANSLATING NORTHWARD...FURTHER SHIFTING THE THREAT. ANOTHER BATCH OF STORMS IS ANTICIPATED ON WEDNESDAY AS A POTENT SHORT WAVE TROUGH AND ASSOCIATED COLD FRONT MOVE THROUGH THE REGION. ATMOSPHERE WILL REMAIN MOIST AND UNSTABLE...WITH AMPLE MOISTURE AND WARM CLOUD DEPTH FOR THE PRODUCTION OF HEAVY RAINFALL. THE KEY HERE WILL BE HOW FAST THE FRONT MOVES THROUGH. TROUGH IS DEEPENING AND SHOWING SIGNS OF BECOMING NEGATIVELY TILTED PER THE MODEL FORECASTS...AND THIS MAY SLOW THE FRONTAL MOVEMENT SOMEWHAT. STORMS WILL HAVE A GOOD NORTHEAST FORWARD MOTION...BUT MAY SEE SOME TRAINING OF STORMS ALONG THE SOUTHWEST TO NORTHEAST FRONTAL BOUNDARY. SOME RIVERS ARE RUNNING HIGH /ZUMBRO...BLACK...BUFFALO... TREMPEALEAU...MISSISSIPPI/ SO WILL HAVE TO WATCH WHERE THE HEAVIEST RAIN FALLS FOR ANY FLOOD POTENTIAL. && .ARX WATCHES/WARNINGS/ADVISORIES... 342 AM CDT TUE JUN 19 2012 WI...NONE. MN...NONE.

LARGE HAIL AND DAMAGING WINDS ARE POSSIBLE. HEAT INDICES THIS AFTERNOON AND EARLY THIS EVENING WILL CLIMB INTO THE 90 TO 100 RANGE ACROSS MUCH OF THE AREA. A COLD FRONT WILL APPROACH THE AREA LATE TONIGHT WITH ANOTHER CHANCE OF THUNDERSTORMS. THERE IS A SLIGHT RISK THAT THESE STORMS COULD BE SEVERE...MAINLY NORTHWEST OF AN AUSTIN MINNESOTA TO ALMA AND OWEN-WITHEE WISCONSIN LINE. THE MAIN THREATS WOULD BE DAMAGING WINDS AND LARGE HAIL. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY THE COLD FRONT WILL MOVE SOUTHEAST ACROSS THE AREA WEDNESDAY. A BROAD AREA OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO ACCOMPANY THE FRONT ACROSS THE AREA. ISOLATED SEVERE STORMS ARE POSSIBLE WEDNESDAY INTO WEDNESDAY EVENING. DAMAGING WINDS AND LARGE HAIL WOULD BE THE MAIN THREATS...BUT THE BIGGER THREAT MAY BE LOCALLY HEAVY RAINS IF MULTIPLE STORMS MOVE ACROSS THE SAME AREA. ADDITIONAL ROUNDS OF HEAVY RAIN FROM THIS MORNING AND LATE TONIGHT INTO WEDNESDAY NIGHT WILL ENHANCE THE POSSIBILITY OF SOME FLOODING...ESPECIALLY NORTH OF A ZUMBRO FALLS MINNESOTA TO BLACK RIVER FALLS WISCONSIN LINE WHERE SOME HEAVY RAINS FELL OVER THE PAST COUPLE DAYS. HOWEVER...ANY HIGH RAINFALL RATES COULD CAUSE FLASH FLOODING. RIVERS ARE EXPECTED TO SEE RISES THROUGH THE WEEK. THUNDERSTORM CHANCES RETURN FROM FRIDAY NIGHT THROUGH SATURDAY NIGHT...BUT IT IS TOO EARLY TO DISCERN SEVERE WEATHER THREATS WITH ANY OF THESE STORMS. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED NORTH THE ZUMBRO FALLS TO BLACK RIVER FALLS LINE EARLY THIS MORNING. SPOTTER ACTIVATION IS POSSIBLE FROM LATE TONIGHT INTO WEDNESDAY EVENING AS THE COLD FRONT MOVES SOUTHEAST ACROSS THE AREA. RAINFALL REPORTS WOULD BE APPRECIATED THIS MORNING. .EMERGENCY MANAGEMENT COORDINATION... NO WEBINAR IS SCHEDULED. RRS
