The episode as NWS ARX wrote it up.
Several township and county roads were closed across Jackson County as a result of flooding. The flooding resulted from ice jams, runoff from melting snow and several rounds of rain. Some of the road closures only lasted a couple of days, while others persisted for weeks.
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 La Crosse, WI wrote its last area forecast discussion before the first event at Apr 8, 5:54 AM CST, 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 654 AM CDT MON APR 8 2013 .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 350 AM CDT MON APR 8 2013 CURRENTLY AS OF 08Z...WATER VAPOR LOOP AND RAP 500MB HEIGHT ANALYSIS SHOWED A POTENT UPPER TROUGH DROPPING SOUTH THROUGH THE SIERRA NEVADA OF CALIFORNIA...RIDGING BEGINNING TO BUILD DOWNSTREAM OVER THE PLAINS...A SHORTWAVE OVER CENTRAL MINNESOTA AND ANOTHER SHORTWAVE IN SOUTHEAST IOWA. ALSO OF NOTE IS A WEST TO EAST ORIENTED UPPER TROUGH OVER NORTHERN ONTARIO...WITH A 70 KT JET STREAK AROUND 250MB LOCATED SOUTH OF IT. DPVA ASSOCIATED WITH THE CENTRAL MINNESOTA SHORTWAVE AND RIGHT ENTRANCE REGION SUPPORT FROM THE AFOREMENTIONED JET STREAK HAS LED TO AN AREA OF SHOWERS...AFFECTING CENTRAL MN...NORTHWEST WI AND NORTHWEST PORTIONS OF THE FORECAST AREA. MEANWHILE TO THE SOUTH...SHOWERS AND THUNDERSTORMS PERSIST ACROSS NORTHERN MISSOURI INTO EASTERN IOWA ASSOCIATED WITH THE SHORTWAVE THERE. THE SHOWERS AND STORMS ARE ALSO AIDED BY A 40-50 KT LOW LEVEL JET AT 850MB ON PROFILER AND VAD WIND DATA...TRANSPORTING MOISTURE AND INSTABILITY FROM THE CENTRAL AND SOUTHERN PLAINS. GOES DERIVED AND RAP PRECIPITABLE WATER DATA SHOWED VALUES OF 1-1.25 INCHES BEING TRANSPORTED NORTHEASTWARD ON THE LOW LEVEL JET. A WARM FRONT COULD BE SEEN AT THE SURFACE SOUTH OF THE CONVECTION ALONG THE MISSOURI/IOWA BORDER. SOUTH OF THIS FRONT...SURFACE DEWPOINTS ARE IN THE MID TO UPPER 50S. THE WEATHER PATTERN IS ABOUT TO BECOME MORE ACTIVE...ALL IN RESPONSE TO THAT POTENT SHORTWAVE TROUGH OVER THE SIERRA NEVADA DIGGING SOUTH. BY 12Z TUESDAY...ALL MODELS HAVE A DEEP TROUGH OVER THE SOUTHWESTERN U.S...WITH A CLOSED LOW NEAR THE FOUR CORNERS...WHICH FORCES STRONG RIDGING TO BUILD UP TOWARDS THE FORECAST AREA. MEANWHILE...TO THE NORTH...THE WEST TO EAST ORIENTED UPPER TROUGH OVER NORTHERN ONTARIO IS PROGGED TO DROP SOUTH TOWARDS LAKE SUPERIOR...RESTRICTING SOME OF THE NORTHWARD PROGRESS OF THE UPPER RIDGING. ADDITIONALLY...THE UPPER TROUGH DROPPING SOUTH TOWARDS THE SUBTROPICAL RIDGE WILL END UP STRENGTHENING THE UPPER JET STREAK ON ITS SOUTH SIDE. BY 12Z TUESDAY...MODELS SHOW A 120 JET STREAK FROM NORTHERN MINNESOTA ACROSS LAKE SUPERIOR. FOR THIS MORNING...FOCUS IS ON THE PAIR OF SHORTWAVES TRACKING THROUGH MINNESOTA AND IOWA. MODELS ARE IN GOOD AGREEMENT SHOWING THESE SHORTWAVES REACHING UPPER MICHIGAN AND LAKE MICHIGAN RESPECTIVELY BY 18Z. EXPECTING THE SHOWERS CURRENTLY ASSOCIATED WITH THEM TO FOLLOW THE SAME TRACK...WITH SUBSIDENCE IN THEIR WAKE HELPING TO END THE PRECIPITATION. DURING THE AFTERNOON...THERE ARE INDICATIONS OF A SHORTWAVE CURRENTLY IN SOUTHEAST WYOMING TRACKING ACROSS THE FORECAST AREA BETWEEN 18-21Z...AROUND PEAK HEATING. AT THE SAME TIME...THE WARM FRONT CURRENTLY ALONG THE MO/IA BORDER IS PROGGED TO HAVE LIFTED NORTH AT LEAST TO I-80...OR POSSIBLY AS FAR NORTH AS U.S. HIGHWAY 20. INITIALLY WOULD BE CONCERNED THAT CONVECTION COULD FIRE...BUT SOUNDINGS SHOW ENOUGH CAPPING IN THE WAKE OF THE MORNING SHORTWAVES...ALONG WITH JUST VERY WEAK CONVERGENCE ON THE FRONT TO PRECLUDE CONVECTION. THUS...HAVE WENT WITH A DRY FORECAST FOR THE AFTERNOON ALONG WITH CLEARING SKIES. WITH 850MB TEMPS CLIMBING TO 5-9C AND AFTERNOON SUN...WE SHOULD BE ABLE TO CLIMB INTO THE 60S SOUTH OF I-90...AND MID 40S TO MID 50S TO THE NORTH. FOR TONIGHT...DESPITE UPPER LEVEL RIDGING BUILDING UP TOWARDS THE AREA...THE SURFACE WARM FRONT LOOKS LIKE IT WILL GET PUSHED SOUTH. THIS IS DUE TO THE UPPER TROUGH DROPPING SOUTH THROUGH CANADA... ALLOWING LOW LEVEL COLD CANADIAN AIR TO FLOW INTO THE NORTHERN PLAINS. IN TURN...THE LOW LEVEL FRONTOGENESIS STRENGTHENS ON THE FRONTAL BOUNDARY. THE 08.00Z NAM IS QUICK TO DEVELOP CONVECTION ON THE FRONTAL BOUNDARY IN THE EVENING...BETWEEN 00-03Z OVER NORTHERN IOWA AND FAR SOUTHWEST WI. MOST OTHER MODELS WAIT UNTIL AFTER 06Z TO HAVE ANY PRECIPITATION ON THE FRONTAL BOUNDARY. WILL LEAN TOWARDS THE MAJORITY AND CONSIDER THE EVENING MOSTLY DRY. IT SHOULD BE NOTED THE NAM IS BY FAR THE FARTHEST NORTH WITH THE WARM FRONT TOO. AFTER 06Z...THERE ARE INDICATIONS OF ANOTHER SHORTWAVE COMING UP TOWARDS THE FORECAST AREA AROUND THE RIDGE...REACHING CENTRAL OR NORTHEAST IOWA BY 12Z TUESDAY. A STRONG SURGE OF MOISTURE TRANSPORT COMBINED WITH THE RIGHT ENTRANCE REGION FORCING OF THE UPPER JET WOULD YIELD PRECIPITATION DEVELOPING AND EXPANDING INTO THE FORECAST AREA. OUTSIDE OF THE 08.00Z SPCWRF-NMM...ALL OTHER AVAILABLE GUIDANCE DEPICTS THIS SCENARIO. THUS...HAVE RAISED PRECIPITATION CHANCES TOWARDS LATE IN THE NIGHT OVER THE SOUTHWEST HALF OF THE FORECAST AREA. .LONG TERM...(TUESDAY THROUGH SUNDAY) ISSUED AT 437 AM CDT MON APR 8 2013 SUMMARIZED BRIEFLY...WET TUESDAY THROUGH THURSDAY. MODELS CONTINUE TO SLOWLY BECOME IN BETTER AGREEMENT WITH THE EVOLUTION OF THE SOUTHWESTERN U.S. TROUGH AS IT HEADS INTO THE PLAINS AND EVENTUALLY INTO THE FORECAST AREA BY LATE IN THE WEEK. STILL...THERE ARE ISSUES TO BE RESOLVED WHICH HAVE IMPACTS ON THE FORECAST. THIS CAN EASILY BE SEEN IN THE TRACK OF THE MAIN SURFACE LOW ASSOCIATED WITH THE TROUGH...WHERE THE 08.00Z GFS HAS A FARTHER SOUTHEAST TRACK RELATIVE TO THE FORECAST AREA COMPARED TO THE 08.00Z NAM/UKMET/CANADIAN/ECMWF. A FARTHER SOUTHEAST TRACK WOULD MEAN MORE OF THE COLD CANADIAN AIR DIVING DOWN INTO THE NORTHERN PLAINS TONIGHT GETS ADVECTED INTO THE FORECAST AREA. THEREFORE TOO...THE GFS ALLOWS MORE PRECIPITATION BETWEEN TUESDAY NIGHT AND THURSDAY TO FALL AS SNOW. HAVE LEANED THE FORECAST MORE TOWARDS A CONSENSUS OF THE REST OF THE MODEL GUIDANCE WITH A MORE NORTHWEST TRACK...THOUGH NOT AS FAR NORTHWEST AS THE 08.00Z NAM. REGARDING SOME DETAILS... FIRST...TUESDAY IS A LITTLE TRICKY. MODELS ARE IN GOOD AGREEMENT THAT THE SHORTWAVE APPROACHING NORTHEAST IOWA LATE TONIGHT WILL MOVE THROUGH THE AREA DURING THE DAY. AGAIN PLENTIFUL FORCING IS PRESENT BETWEEN THE RIGHT ENTRANCE REGION OF THE UPPER JET...THE SURGE OF 850MB MOISTURE TRANSPORT AND DPVA FROM THE SHORTWAVE. MOISTURE IS ALSO PLENTIFUL WITH PRECIPITABLE WATER VALUES CLIMBING UP TO AN INCH OR SO. THUS...SEEING PRECIPITATION LOOKS LIKE A SAFE BET. THE BIG ISSUE IS THE QPF. THE 08.00Z GFS/NAM/REGIONAL CANADIAN AND HIRES-ARW MODELS ALL SHOW POTENTIAL OF OVER AN INCH OF QPF TO FALL OVER THE NORTHWEST HALF OF THE FORECAST AREA. THIS IS AN AREA THAT DOES NOT NEED THE RAIN... PARTICULARLY OVER WEST CENTRAL WISCONSIN WHERE FLOOD WARNINGS ARE OUT ON THE TREMPEALEAU AND BLACK RIVER. ON THE OTHER HAND...THE 08.00Z ECMWF AND ITS PREVIOUS RUN DEPICT THE UP TO AN INCH OF QPF TO FALL MORE TO THE SOUTH. HPC PREFERRED THE ECMWF SCENARIO AND HAVE WENT ALONG WITH IT. DEFINITELY NEED TO WATCH WHERE THE QPF FALLS. ALSO ADDED A SLIGHT CHANCE OF THUNDER FOR THE ENTIRE DAY SOUTH OF I-90...CORRELATING WITH SOME WEAK ELEVATED CAPE PRESENT. TUESDAY NIGHT AND EVEN WEDNESDAY CONTINUE TO LOOK LIKE A SLAM DUNK FOR PRECIPITATION...ESPECIALLY TUESDAY NIGHT. DURING THIS PERIOD A NEW SURGE OF 850MB MOISTURE TRANSPORT FORMS AHEAD OF THE EASTWARD PROGRESSING UPPER TROUGH...IMPINGING INTO THE TIGHT LOW TO MID LEVEL FRONTOGENESIS ZONE IN PLACE. ADDITIONALLY...THAT UPPER JET STREAK JUST LINGERS OVER UPPER MICHIGAN TO PROVIDE UPPER LEVEL DIVERGENCE OVER THE FORECAST AREA. WITH PRECIPITABLE WATER VALUES CONTINUING TO HOVER IN AT LEAST THE 0.75 TO 1 INCH RANGE...HIGHEST IN THE SOUTH...DEFINITE CONCERN HERE FOR AT LEAST MODERATE TO POSSIBLY HEAVY PRECIPITATION. NOTE THE WORD PRECIPITATION HERE. ALL MODELS SHOW THAT THE LOW LEVEL NORTHEAST FLOW ON THE NORTH SIDE OF THE SURFACE LOW WILL DRAG DRIER...COLDER AIR SOUTH INTO THE AREA FROM ONTARIO. AS A RESULT...WE ARE GOING TO RUN INTO A SITUATION OF COLD AIR UNDERCUTTING A WARM LAYER...WHICH MEANS POTENTIAL FOR MIXED PRECIPITATION TYPES. THE BIG QUESTION MARKS ARE: 1. DO 2 METER TEMPERATURES FALL BELOW FREEZING TUESDAY NIGHT AND 2. IF SO...WILL THE WARM LAYER STILL BE WARM ENOUGH TO ALLOW FOR LIQUID AND 3. ARE OBJECTS GOING TO GET COLD ENOUGH TO RESULT IN ICE ACCUMULATION FOR NOW HAVE INTRODUCED BOTH A MENTION OF SLEET AND FREEZING RAIN INTO NORTHWEST SECTIONS OF THE FORECAST AREA AFTER MIDNIGHT TUESDAY NIGHT INTO WEDNESDAY MORNING. THIS WOULD MOST LIKELY BE THE AREA THAT SEES THE COLDEST LOW LEVEL AIR. ANTICIPATING THAT DIURNAL HEATING ON WEDNESDAY SHOULD BOOST TEMPERATURES WARM ENOUGH TO RESULT MAINLY IN RAIN BY AFTERNOON. STILL...ENDED UP COOLING HIGH TEMPERATURES SOME DUE TO ANTICIPATION OF RAIN ALL DAY. HEADING INTO WEDNESDAY NIGHT AND THURSDAY...ATTENTION TURNS TO ACCUMULATING SNOW POTENTIAL AS THE CORE OF THE UPPER TROUGH MOVING FROM THE CENTRAL PLAINS INTO THE FORECAST AREA. A VERY GOOD FORCING SIGNAL SHOWS UP FOR PRECIPITATION BETWEEN 500MB HEIGHTS FALLING AND A TROWAL WRAPPING BACK TOWARDS THE FORECAST AREA. RAISED PRECIPITATION CHANCES GIVEN THE GOOD SIGNAL. 850MB TEMPS COOL AS THE UPPER TROUGH APPROACHES...DOWN TO 0 TO -6C BY 12Z THURSDAY... COLDEST NORTHWEST. FURTHER COOLING CONTINUES THROUGH THE DAY THURSDAY. LOWERED BOTH LOW AND HIGH TEMPERATURES FOR THIS PERIOD. HOW MUCH SNOW FALLS IS GOING TO DEPEND ON RATE...WARMTH OF THE BOUNDARY LAYER AND GROUND TEMPERATURES. HARD TO SPECULATE ON AMOUNTS AT THIS TIME...BUT A FEW INCHES OF ACCUMULATION SEEM POSSIBLE... ESPECIALLY OVER THE NORTHWEST HALF OF THE AREA. 437 AM UPDATE...NOTICED THAT BOTH THE 08.00Z ECMWF AND 08.00Z/06Z NAM INDICATE A DRY SLOT COMING THROUGH ALOFT TO SCOUR OUT THE ICE IN THE CLOUDS FOR WEDNESDAY NIGHT AND THURSDAY. IF THIS COMES TO FRUITION...WE MAY BE DEALING MORE WITH RAIN / FREEZING RAIN VERSUS SNOW...AND THUS BACK TO WONDERING ABOUT OBJECT TEMPERATURES. BEYOND THURSDAY...MODELS ARE STRUGGLING WITH HOW FAST TO LIFT OUT THE UPPER TROUGH. THE NEW 08.00Z ECMWF REALLY SLOWED IT DOWN COMPARED TO ITS PREVIOUS RUN AND OTHER MODEL GUIDANCE...WITH AN UPPER LOW STILL OVER NORTHERN WISCONSIN AT 00Z SATURDAY. IF THIS COMES TO FRUITION...POTENTIAL FOR SOME MINOR SNOW ACCUMULATIONS WOULD CONTINUE AT LEAST INTO FRIDAY MORNING. ALL OTHER GUIDANCE SUGGESTS THE TROUGH IS AT LEAST OVER THE EASTERN GREAT LAKES AT THIS TIME...ALLOWING CANADIAN HIGH PRESSURE TO BUILD INTO MINNESOTA. FOR NOW...STAYED WITH A CONSENSUS APPROACH WHICH IS TO KEEP SOME 20-30 PERCENT CHANCES IN THURSDAY NIGHT AND A DRY FRIDAY. DRY AND COOL CONDITIONS LOOK TO PERSIST INTO AT LEAST SATURDAY AS THAT CANADIAN HIGH MOVES THROUGH. ATTENTION THEN TURNS TO BROAD TROUGHING FORMING OVER THE PACIFIC NORTHWEST AND NORTHERN ROCKIES FOR THE REST OF THE WEEKEND. 08.00Z ECMWF/GFS/GFS ENSEMBLES ALL HAVE A POTENT SHORTWAVE COMING OUT OF THIS TROUGH AND HEADING INTO NORTHERN MN BY 00Z MONDAY. WARM ADVECTION AHEAD OF THIS TROUGH EXPECTED TO YIELD SOME RAIN...AND POSSIBLY SNOW INITIALLY UNTIL THE BOUNDARY LAYER WARMS. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z TUESDAY MORNING) ISSUED AT 654 AM CDT MON APR 8 2013 A LOW PRESSURE SYSTEM WILL PRODUCE SHOWERS AT KLSE THROUGH 08.15Z. IN THE WAKE OF THIS FRONT...SUBSIDENCE WILL BUILD ACROSS THE REGION. THE BUFKIT SOUNDINGS SUGGEST THAT A MVFR DECK WILL BECOME TRAPPED UNDER THE SUBSIDENCE INVERSION. HOWEVER THINKING THAT THE MODELS MIGHT BE HAVING ISSUES WITH THE LOW LEVEL MOISTURE FROM THE DENSE FOG ACROSS SOUTHWEST MINNESOTA AND NORTHWEST IOWA. IF THIS WAS EARLIER IN THE NIGHT WOULD EXPECT THAT OUR AREA WOULD ALSO SEE DENSE FOG AND LOW CEILINGS. HOWEVER WITH THE SUN ALREADY UP...THINKING THAT THE PROBABILITIES FOR THIS OCCURRING IS MUCH LOWER...SO OPTED TO GO MORE OPTIMISTIC AND JUST WENT WITH SOME SCATTERED MVFR CLOUDS. FOR TONIGHT...ANOTHER LOW PRESSURE SYSTEM WILL MOVE INTO THE REGION. WENT WITH THE SLOWER GFS AND ECMWF SOLUTIONS...SO DELAYED THE ONSET OF THE RAIN SHOWERS BY ABOUT 6 HOURS IN THE TAFS. THIS WOULD MEAN ASTART OF AROUND 09.08Z FOR KRST AND 09.10Z FOR KLSE. && .HYDROLOGY... ISSUED AT 350 AM CDT MON APR 8 2013 RIVER STATUS... THE TREMPEALEAU RIVER NEAR DODGE WILL REMAIN ABOVE FLOOD STAGE AND ALLOW FOR MINOR FLOODING TO CONTINUE THROUGH AT LEAST THIS EVENING. THE BLACK RIVER AT BLACK RIVER FALLS IS ANTICIPATED TO EXPERIENCE MINOR FLOODING THIS EVENING AND THROUGH THE DAY TUESDAY. THE REST OF THE BLACK RIVER IS ALSO EXPECTED TO SEE WITHIN BANK RISES OVER THE NEXT SEVERAL DAYS. OTHER RIVERS ACROSS THE AREA WILL LIKELY SEE WITHIN BANK RISES WITH PERIODIC RAINFALL OVER THE NEXT SEVERAL DAYS BUT ARE NOT EXPECTED TO FLOOD AT THIS TIME. SNOW PACK... RECENT COOPERATIVE OBSERVER REPORTS SHOW SNOW PACK IS MAINLY ALONG AND NORTH OF HIGHWAY 10 WITH 2 TO 4 INCHES OF SNOW DEPTH IN PLACES. THE DEEPEST SNOW PACK IS OVER THE NORTHERN MOST PARTS OF TAYLOR WHERE AROUND 4 TO 6 INCHES OF SNOW REMAINS ON THE GROUND. SNOW WATER EQUIVALENT OF 2 TO 4 INCHES IS MAINLY NORTH OF HIGHWAY 10 WITH THE GREATEST SNOW WATER EQUIVALENT IN NORTHERN TAYLOR COUNTY. RAINFALL... BEFORE NOON...COULD SEE UPWARDS OF 1/4 INCH OR SO OF RAINFALL... GREATEST OVER TAYLOR COUNTY. ATTENTION THEN TURNS TO THE LATE TONIGHT THROUGH WEDNESDAY TIME PERIOD WHERE PERIODS OF RAINFALL COULD TOTAL FROM 1 TO 3 INCHES. THE HEAVIEST RAINFALL RIGHT NOW IS ANTICIPATED SOUTH OF INTERSTATE 90...WHERE RIVERS HAVE A BETTER CHANCE OF HANDLING IT. HOWEVER...THERE IS SOME UNCERTAINTY AND HEAVIER RAINFALL COULD OCCUR FARTHER NORTH THAN EXPECTED. TEMPERATURES... HIGHS TODAY ARE EXPECTED TO BE AROUND 50 NORTH OF I-94 TO THE LOWER TO MIDDLE 60S SOUTH OF I-90. HIGHS WILL COOL QUITE A BIT FOR TUESDAY THROUGH THURSDAY...ESPECIALLY FOR THURSDAY WHERE READINGS MAY NOT REACH 40. STILL...THESE TEMPERATURES WILL CONTINUE TO MELT ANY EXISTING SNOWPACK. FROST DEPTH... AS OF APRIL 4TH...FROST DEPTHS //WHICH ARE OBSERVED EVERY MONDAY AND THURSDAY//ACROSS THE AREA REMAIN DEEP...AVERAGING AROUND 1 FOOT TO 1 1/2 FEET SOUTH OF I-90...AND UP TO 3 FEET ACROSS PORTIONS OF NORTH CENTRAL WISCONSIN. THIS FROST WILL ACT TO ENHANCE RUNOFF OF SNOW MELT AND PRECIPITATION INTO STREAMS AND RIVERS. SUMMARY... POSSIBILITY OF FLOODING REMAINS A CONCERN THROUGH THIS WEEK WITH ADDITIONAL SNOW MELT AND ESPECIALLY THE RAINFALL LATE TONIGHT THROUGH WEDNESDAY. OVERALL...APPEARS THE BIGGEST FLOODING CONCERNS ARE ALONG THE BLACK AND TREMPEALEAU RIVERS FOR THE NEXT FEW DAYS. WILL CONTINUE TO KEEP AND EYE ON THIS.
