The episode as NWS MPX wrote it up.
A line of thunderstorms that developed in South Dakota and moved across Minnesota, and into west central Wisconsin, produced wind damage in Star Prairie Township less than a mile northeast of the Village of Somerset.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Twin Cities, MN wrote its last area forecast discussion before the first event at Jul 9, 6:10 AM CST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 710 AM CDT TUE JUL 9 2013 .UPDATE... 12Z AVIATION DISCUSSION ADDED BELOW. && .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 410 AM CDT TUE JUL 9 2013 MAIN CONCERN IN THE SHORT TERM REVOLVES ON EVOLUTION OF STORMS CURRENTLY ACROSS THE DAKOTAS THROUGH THE MORNING...FOLLOWED BY WHERE THUNDERSTORMS REDEVELOP THIS AFTERNOON AND TRAVEL THIS EVENING. IT IS THE AFTERNOON/EVENING ACTIVITY THAT WILL ALSO HAVE A SEVERE THREAT. WIND AND HAIL WILL BE THE PRIMARY THREATS...THOUGH DEPENDING ON WHERE BOUNDARIES ARE LEFT OVER FROM CONVECTION THIS MORNING...THERE WILL ALSO BE THE SMALL CHANCE FOR TORNADOES ON ANY LEFT OVER OUTFLOW BOUNDARIES. AT 3 AM...WE WERE DEALING WITH A BIFURCATED LLJ IN TERMS OF MOISTURE TRANSPORT MAXIMA...WITH ONE BRANCH DRIVING CONVECTION CURRENTLY MOVING ACROSS THE DAKOTAS AND THE OTHER DRIVING ANOTHER CLUSTER ALONG THE NEB/IA BORDER. THIS SRN BRANCH WILL TRACK ACROSS IA THROUGH THE MORNING...KEEPING THAT CONVECTION SOUTH OF MN WHILE BECOMING THE MAIN LLJ FOR POTENTIAL AFTERNOON ACTIVITY. FOR THE MPX AREA...IT IS THE MCS THIS MORNING OVER SODAK THAT WILL BE OUR PROBLEM. 3Z RAP MUCAPE ANALYSIS SHOWS A RIBBON OF 1000-1500 J/KG OF MUCAPE EXTENDING FROM THE MADISON/CANBY AREA...ESE TROUGH ROCHESTER AND LA CROSSE. AS A RESULT...ANTICIPATE THIS BAND OF THUNDERSTORMS WILL CONTINUE ESE ALONG THIS CAPE GRADIENT. AT ITS CURRENT PACE...SHOULD ENTER WRN MN SHORTLY BEFORE 5 AM...REACH THE I-35 CORRIDOR BETWEEN 7 AND 8 AM AND EVENTUALLY THE LSE/EAU AREAS BY LATE MORNING. THE BULK OF THE CONVECTION WITH THIS LINE SHOULD TRACK SOUTH OF I-94 THIS MORNING. AS FOR SEVERE THREAT...THE STRONG/SEVERE LINE OF STORMS THAT MOVED ACROSS SODAK HAS NOW MERGED WITH THE WAA ACTIVITY THAT HAD DEVELOPED OUT AHEAD OF IT...WITH ONE LINE NOW EVIDENT ON REGIONAL RADAR ANALYSIS. WILL HAVE TO WATCH HOW THIS LINE EVOLVES OVER THE NEXT HOUR TO SEE WHAT KIND OF SEVERE THREAT IT WILL POSE. IN THE NEXT HOUR...IF IT BEGINS TO BOW OUT AND ACCELERATE...THEN A WIND THREAT WILL EXIST THROUGH THE MORNING AS IT TRACKS ACROSS MN. WITH THE RAP AT 3Z ANALYZING 20-30 KTS OF 0-3KM SHEAR OUT AHEAD OF THE SYSTEM...IT IS PLAUSIBLE THAT THAT COULD HAPPEN...THOUGH IN THE END IT MAY BE DIFFICULT TO GET ANY SEVERE STRENGTH WINDS THROUGH THE STABLE BOUNDARY LAYER...SO AGREE WITH SPC MCD THAT SEVERE THREAT WILL BE FAIRLY MARGINAL. FOR THIS AFTERNOON...MANY A QUESTION MARKS STILL REMAIN IN PLACE. THIS BIGGEST ISSUE IS HOW WILL STORMS THIS MORNING IMPACT WHAT HAPPENS LATER. THE MAIN QUESTION IS DOES THE ATMOSPHERE HAVE ENOUGH TIME TO RECHARGE FROM STORMS MOVING THROUGH LARGELY IN THE 10-18Z TIME FRAME? FIRST WORD OF WARNING FOR THE ARM CHAIR FORECASTERS OUT THERE...THE CAMS MAY NOT BE ALL THAT RELIABLE FOR WHAT HAPPENS LATER THIS AFTERNOON AS ALL OF THEM ARE HANDLING CURRENT CONVECTION QUITE POORLY /INCLUDING ALL MEMBERS OF THE 3Z HOPWRF/. PROBLEM IS...OUTSIDE OF THE SPCWRF...NONE OF THE CAMS SNOW THUNDERSTORMS MOVING ACROSS THE AREA OUTLINED IN THE PARAGRAPH ABOVE...MANY /INCLUDING THE HOPWRF MEMBERS/ HAVE NOTHING MOVING ACROSS THE MPX AREA THIS MORNING...SO HARD TO PUT MUCH STOCK IN WHAT THEY ARE DOING THIS AFTERNOON. THE ONLY ONE TO BE SOMEWHAT CLOSE TO REALITY THIS MORNING /SPCWRF/...SHOWS VERY LITTLE CONVECTION REDEVELOPING IN THE MPX AREA THIS AFTERNOON. CERTAINLY A BIG PLUS FOR THE AFTERNOON...IS OVER THE LAST 24 HOURS...MODELS HAVE SLOWED UP THE PROGRESSION OF THE FRONT ACROSS THE MPX AREA...WHICH LIKELY EXPLAINS WHY HIGHER SEVERE PROBABILITIES WERE PULLED NORTHWEST WITH THE DAY1 SPC CONVECTIVE OUTLOOK. CURRENT MODEL BLEND WOULD SAY THE FRONT MOVES INTO THE NW MPX CWA AROUND 20Z...THE TWIN CITIES AROUND 00Z AND FINALLY CLEARS EAU AREA SHORTLY AFTER 3Z. THIS PUTS THE FRONT ACROSS MUCH OF THE AREA DURING PEAK HEATING...THOUGH IT IS STILL DEBATABLE HOW MUCH HEATING WE WILL SEE BEHIND THE MORNING CONVECTION. IF CURRENT FORECAST WERE TO HOLD...WITH TEMPERATURES REBOUNDING INTO THE MID 80S TO NEAR 90...WITH DEWPS IN THE LOWER 70S...THEN WE SHOULD HAVE NO PROBLEM GENERATING 2000-3500 J/KG OF MLCAPE AHEAD OF THE BOUNDARY AS THE NAM/GFS DO. FROM THE SHEAR PERSPECTIVE...A 40-60 KT MID LEVEL JET MOVING IN WITH THE UPPER WAVE THIS AFTERNOON/EVENING WILL PROVIDE PLENTY OF DEEP LAYER SHEAR TO SUPPORT UPDRAFT ROTATION AND STORM ORGANIZATION...BUT THE 0-3KM SHEAR IS LOOKING MORE SUSPECT ACROSS THE MPX AREA TO REALLY DRIVE UP A TORNADO THREAT. THE REASON FOR THE POOR LOW LEVEL SHEAR IS THAT THE PRESSURE PATTERN AHEAD OF THE FRONT WILL BE FAIRLY BAGGY...WITH LIGHT PREFRONTAL WINDS EXPECTED. IN ADDITION...THE CORE OF A 30-40 KT LLJ WILL EXTEND FROM CENTRAL IA TOWARD NE WIS...STAYING JUST SE OF THE MPX AREA. COMBINED...THE WEAK SFC WINDS AND BETTER LLJ BEING JUST SE OF THE MPX CWA RESULT IN MARGINAL 0-1 KM AND 0-3 KM SHEAR /MAINLY 20 KTS OR LESS/. BESIDE THE WEAKER SHEAR...THE WEAK SFC WINDS OUT AHEAD OF THE FRONT WILL ALSO LIMIT THE AMOUNT OF CONVERGENCE ALONG IT...WHICH MAY HELP EXPLAIN WHY MANY OF THE CAMS /OUTSIDE OF THE 3Z HOPWRF/ STRUGGLE TO GENERATE MUCH CONVECTION ALONG THE BOUNDARY THIS AFTERNOON. IN SUMMARY...CONFIDENCE IS HIGH THAT MCS CURRENTLY OVER ERN SODAK WILL TRACK ACROSS AREAS SOUTH OF I-94 THIS MORNING. BECAUSE OF THIS...CONFIDENCE IN HOW THE AFTERNOON PLAYS OUT IS CONSIDERABLY DIMINISHED. BUT...GIVEN FRONTAL TIMING...EXPECT AT LEAST SCT STORMS TO DEVELOP ALONG THE FRONT BETWEEN 19Z AND 21Z THAT WILL THEN TRACK SE THIS EVENING WITH THE FRONT. GIVEN DEGREE OF INSTABILITY AND BULK SHEAR...LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY THREAT. THE WEAKER LOW LEVEL SHEAR MEANS THAT UNLESS A STORM CAN LATCH ON TO A REMNANT OUTFLOW BOUNDARY...THE TORNADO THREAT APPEARS TO BE RELATIVELY LOW...THOUGH NOT NEGLIGIBLE. .LONG TERM...(WEDNESDAY THROUGH MONDAY) ISSUED AT 410 AM CDT TUE JUL 9 2013 THE FIRST HALF OF THE PERIOD WILL START OFF DRY AS LARGE SCALE SUBSIDENCE DOWNSTREAM OF THE UPPER LEVEL RIDGE AXIS BUILDS AN AREA OF SURFACE HIGH PRESSURE ACROSS THE UPPER MIDWEST. FORECAST SOUNDINGS SHOW A DRY PROFILE WITH PWATS ONLY AROUND 0.75 INCHES...ALONG WITH LITTLE POTENTIAL FOR CLOUDS DURING THE DAY ON WEDNESDAY. WINDS WILL GO CALM OVERNIGHT ALLOWING AN INVERSION TO SET UP AND TEMPERATURES TO COOL DOWN TO THE UPPER 50S ACROSS MOST LOCATIONS...WITH LOW 60S EXPECTED IN AND AROUND THE METRO DO TO THE HEAT ISLAND. THURSDAY WILL BE DRY AS WELL WITH THE SURFACE HIGH STILL SUPPRESSING ANY CHANCE OF PRECIP. BY THURSDAY NIGHT THE SURFACE HIGH WILL DRIFT EASTWARD AS THE THERMAL RIDGE APPROACHES FROM THE WEST...AND SOUTHERLY WINDS ON THE BACK SIDE WILL KEEP OVERNIGHT LOWS IN THE MID TO UPPER 60S ACROSS WESTERN MINNESOTA. FRIDAY SHOULD BE MUCH WARMER THAN CURRENTLY FORECAST BY THE NUMERICAL MODELS. BOTH THE GFS AND ECMWF 09.00 HAVE H850 TEMPS 20-22C...WITH SOUTHERLY WINDS OF 30KTS...YET FOR SOME REASON THE FORECAST SOUNDINGS ONLY SHOW MIXING UP TO AROUND 900MB. THIS IS CONTRADICTORY TO THE SIMPLE PROPERTIES THAT GOVERN THE ATMOSPHERE. GIVEN A MID JULY PROFILE THAT IS CLOUD FREE...TOGETHER WITH THE POTENTIAL FOR MECHANICAL MIXING...HAVE VERY HIGH CONFIDENCE THAT AFTERNOON TEMPERATURES WILL CLIMB INTO THE 90S ACROSS SOUTHWEST MINNESOTA. ON SATURDAY CONFIDENCE IN TEMPERATURES DECREASES CONSIDERABLY AS A FRONTAL BOUNDARY/TROUGH OF LOW PRESSURE STALLS OUT FROM SOUTHWEST TO NORTHEAST OVER THE UPPER MIDWEST. THIS WILL INTRODUCE CHANCES FOR SHOWERS AND THUNDERSTORMS...WHICH WILL GREATLY AFFECT AFTERNOON HIGHS. THEREFORE DID NOT STRAY TOO MUCH FROM BLENDED GUIDANCE...AND CONTINUE TO HAVE CHANCES FOR PRECIP INTO EARLY NEXT WEEK. THE BEST CHANCE FOR RAIN...WITH 1-3 INCH AMOUNTS VERY LIKELY AT A FEW LOCATIONS ACROSS THE NORTHWEST NEAR CANBY/ALEXANDRIA/ST CLOUD...WILL BE LATE FRIDAY NIGHT INTO SATURDAY MORNING. LOOKING AHEAD...THE THERMAL RIDGE WILL TAKE ON A POSITIVE TILT OVER THE UPPER MISSISSIPPI RIVER VALLEY. ON SUNDAY THE ECMWF DRIVES A SHORTWAVE ALONG THE US/CANADIAN BORDER THAT SUPPRESSES THE RIDGE...WHILE THE GFS IS A DAY SLOWER WITH THIS FEATURE. ALSO...AS ALLUDED TO EARLIER OVERCAST SKIES WILL GREATLY IMPACT HIGH TEMPS SO DID NOT HAVE THE CONFIDENCE TO DEVIATE FROM A CONSENSUS APPROACH. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING) ISSUED AT 700 AM CDT TUE JUL 9 2013 MATURE MCS WORKING ACROSS THE AIRSPACE THIS MORNING MOVING EAST AT ABOUT 35 KTS HAS BEEN TIMED THROUGH TAFS TO START OUT THIS MORNING. OTHER THAN A GUST TO 50 KTS AT RWF...ALL SITES TO THE WEST HAVE BEEN TOPPING OUT AT 40 KTS ON GUSTS. HARD TO SAY WHAT WILL HAPPEN THIS AFTERNOON AS THERE WILL BE A RECOVERY TIME FROM MORNING STORMS. HRRR SEEMS A BIT QUICK WITH THE FRONT...BUT SLOWING DOWN THE HRRR A BIT WOULD SUGGEST SCT TSRA POSSIBLE FROM RWF TO STC EAST AFTER 20Z...BUT CONFIDENCE LOW ON THAT HAPPENING NOW. WIND SPEEDS DO NOT PICK UP UNTIL YOU GET BEHIND THE FRONT AND SHOULD GUST TO 20-25 KTS BEHIND THE FRONT FOR A COUPLE OF HOURS. KMSP...TSRA STILL ON TARGET TO ARRIVE BETWEEN 1300 AND 1330Z AND OUT AROUND 1530. EXPECT BRIEF GUSTS UP AROUND 40 MPH OUT OF THE WEST...ALONG WITH BRIEF HEAVY DOWNPOURS. LOW CONFIDENCE ON WHAT HAPPENS THIS AFTERNOON...BUT THERE IS THE POTENTIAL FOR MORE TSRA BETWEEN 21Z AND 00Z BEFORE FRONT CLEARS EVERYTHING OUT AND ITS VFR THE REST OF THE WAY. /OUTLOOK FOR KMSP/ WED...VFR.
