AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 152 PM CDT SAT JUN 28 2014 .SHORT TERM...(TONIGHT THROUGH SUNDAY NIGHT) ISSUED AT 152 PM CDT SAT JUN 28 2014 SEVERE THREAT INCLUDING HEAVY RAINFALL REMAIN THE MAIN CONCERN THROUGH THE REST OF THIS WEEKEND. WATER VAPOR LOOP AND RAP ANALYSIS HAS A NEGATIVELY TILTED MID-LEVEL TROUGH/WEAK SURFACE COLD FRONT EXTENDING FROM WESTERN ND THROUGH THE CENTRAL PLAINS. FEED OF MOISTURE TRANSPORT AHEAD OF THE TROUGH WAS PRODUCING SEVERAL LINES OF SHOWERS/THUNDERSTORMS ACROSS MN/IA...AND INTO THE CENTRAL PLAINS. OTHERWISE...A WARM AND MUGGY AIRMASS WAS IN PLACE ACROSS THE AREA WITH TEMPERATURES IN THE LOWER 80S AND DEW POINTS IN THE UPPER 60S TO THE LOWER 70S. WILL BE WATCHING THE PROGRESSION OF THE MID-LEVEL TROUGH/WEAK SURFACE COLD FRONT AND CONVECTION THROUGH THE REST OF THIS AFTERNOON INTO TONIGHT. CONSENSUS OF MESO-WRF MODELS CONTINUE TO ENHANCE THUNDERSTORM ACTIVITY ALONG AND AHEAD OF THIS TROUGH/FRONT AS IT MOVES INTO THE AREA LATE THIS AFTERNOON/EARLY EVENING. NAM 0-1KM MLCAPE IN THE 500-1000J/KG RANGE WITH 0-3KM BULK SHEAR AROUND 20KT. MEANWHILE... PRECIPITABLE WATER VALUES APPROACHING 2 INCHES. SO...INGREDIENTS ARE THERE FOR PERHAPS SOME ORGANIZED LINE/S OF THUNDERSTORMS MOVING INTO THE AREA LATE THIS AFTERNOON AND EARLY EVENING WITH THE MAIN IMPACT BEING BOUTS OF HEAVY RAINFALL AND POTENTIAL FOR DAMAGING WINDS. RAP ALSO SHOWING SOMEWHAT ENHANCED NON- TORNADIC SUPERCELL SIGNATURE FOR PERHAPS A BRIEF SPIN-UP OF AN ISOLATED TORNADO OR TWO ON THE LEADING EDGE OF THE LINE/S OF CONVECTION. APPEARS RIGHT NOW THE MAIN SEVERE THREAT WILL BE IN THE 4-10 PM TIME FRAME. APPEARS THE TROUGH AND BULK OF THE SHOWER/THUNDERSTORMS WILL EXIT THE AREA AFTER MIDNIGHT. ON SUNDAY...AFTER A BRIEF MORNING LULL IN THE ACTION...PLAN ON ANOTHER ROUND OF THUNDERSTORMS TO MOVE BACK INTO THE AREA MAINLY LATER IN THE AFTERNOON INTO SUNDAY NIGHT AS ANOTHER MID-LEVEL TROUGH INTERACTS WITH THE SURFACE FRONTAL BOUNDARY LAID OUT ACROSS SOUTHERN WI THROUGH CENTRAL IA. THERE WILL BE AMPLE 0-3KM BULK SHEAR IN THE 30-35KT RANGE AND MUCAPE IN THE 1800-2500J/KG GOING INTO SUNDAY EVENING FOR A ANOTHER POTENTIAL FOR ORGANIZED LINES OF THUNDERSTORMS WITH DAMAGING WINDS AND HEAVY RAINFALL. MID-LEVELS WILL ALSO BE IN COOLING MODE FOR STEEPER LAPSE RATES AND LARGE HAIL POTENTIAL. ALSO...CANNOT RULE OUT A BRIEF TORNADO OR TWO AS WELL. .LONG TERM...(MONDAY THROUGH SATURDAY) ISSUED AT 152 PM CDT SAT JUN 28 2014 ANOTHER ROUND OF SEVERE WEATHER/HEAVY RAINFALL LIKELY MONDAY. MODELS HAVE BEEN COMING INTO BETTER AGREEMENT IN GENERATING A MID- LEVEL WAVE OVER THE CENTRAL PLAINS AND RACING ITO NORTHEAST ACROSS THE STALLED OUT BOUNDARY RUNNING FROM SOUTHERN WI INTO CENTRAL IA. MODEL CONSENSUS 0-3KM MUCAPE RUNNING SOMEWHERE AROUND 1200J/KG ALONG/NORTH OF I-94...TO NEAR 3000J/KG ACROSS NORTHEAST IA. THE NAM IS THE MOST BALLISTIC WITH CAPE NEARING 5500J/KG BY AFTERNOON ACROSS NORTHEAST IA. NAM/GFS/ECMWF ALL INDICATING AMPLE 0-3KM BULK SHEAR IN THE 35-55KT RANGE. SO...LOOKS LIKE ANOTHER SHOT FOR SEVERE THUNDERSTORMS WITH HEAVY RAINFALL. TORNADO/LARGE HAIL THREAT ALSO LOOKS HIGHER FOR PORTIONS OF SOUTHWEST WI INTO NORTHEAST IA WHERE NAM INDICATES STORM RELATIVE HELICITY VALUES IN THE 500-700 RANGE. LOOK FOR THE BULK OF THIS CONVECTION TO PUSH EAST OF THE AREA DURING THE MID-LATE EVENING HOURS. FOR TUESDAY THROUGH THURSDAY...GFS/ECMWF INDICATING COOLER/CYCLONIC FLOW DOMINATING THE REGION. TUESDAY LOOKS PRIME FOR SOME INSTABILITY SHOWERS/ISOLATED THUNDERSTORMS MAINLY TUESDAY AFTERNOON WITH COLDEST POOL OF AIR ALOFT. FOR FRIDAY/SATURDAY...SOME DIFFERENCES BETWEEN THE ECMWF/GFS ARISE AS THE ECMWF BUILDS A FLAT RIDGE INTO THE REGION WHILE THE GFS MAINTAINS COOLER/BROAD CYCLONIC FLOW. EITHER WAY...LOOKS LIKE A COUPLE ROUNDS OF SHOWERS/THUNDERSTORMS WILL BE POSSIBLE. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON) ISSUED AT 1205 PM CDT SAT JUN 28 2014 UPPER LEVEL SHORTWAVE TROUGH SLATED TO DRIVE EAST/NORTHEAST ACROSS THE REGION TONIGHT...AND WILL SERVE AS THE MAIN FOCUS FOR A LINE OF TSRA/SHRA THAT WILL IMPACT KRST/KLSE BETWEEN 22-03Z. EXPECTING IFR/MVFR CONDITIONS WITH THE STORMS...ALONG WITH THE LIKELIHOOD OF ENHANCED WINDS. VERY HEAVY RAIN WILL ALSO ACCOMPANY THE STRONGER STORMS. MOST OF THE ACTIVITY WILL HAVE MOVED EAST BY 03Z...WITH SOME LINGERING SHOWERS POSSIBLE INTO THE EARLY OVERNIGHT. MODELS THEN HINT THAT LOW STRATUS COULD AGAIN DEVELOP UNDER THE LOW LEVEL INVERSION TOWARD 12Z ON SUN - SIMILAR TO WHAT OCCURRED THIS MORNING. LOOKS REASONABLE ENOUGH TO ADD TO THE FORECAST AT THIS TIME...BUT WILL NEED TO EVALUATED LATER TO SEE IF THE POTENTIAL IS STILL PROBABLE. && .HYDROLOGY... ISSUED AT 152 PM CDT SAT JUN 28 2014 PLAN ON PERIODS OF HEAVY RAINFALL THROUGH THE REST OF THE WEEKEND AND AGAIN ON MONDAY AS SEVERAL ROUNDS OF THUNDERSTORMS ARE FORECAST TO MOVE THROUGH. DUE TO MOSTLY TRANSITORY NATURE OF THE CONVECTION...FLASH FLOODING WILL LIKELY END UP BEING MORE OF A LOCALIZED THREAT. HOWEVER...IF TRAINING OCCURS...HEAVY RAINFALL COULD BE PROBLEMATIC. THIS COULD BE THE ISSUE MORE ON MONDAY. WILL HAVE TO WATCH EVOLUTION OF THIS ACTIVITY AND POTENTIAL FOR A FLASH FLOOD WATCH PLAN ON THE MAIN STEM OF THE MISSISSIPPI TO REMAIN HIGH THROUGH NEXT WEEK DUE TO ADDITIONAL RAINFALL THROUGH MONDAY. && .ARX WATCHES/WARNINGS/ADVISORIES...
