The episode as NWS FGF wrote it up.
Persistent thunderstorms formed over west central Minnesota on the evening of the 11th, fed by strong moisture transport from the south-southwest. The heaviest rain fell along the U. S. Highway 10 corridor, from Perham to New York Mills to Wadena. The most rain fell at Wadena, where eight inches was reported. This resulted in basement, street, and trailer park flooding.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND FORKS ND 1143 PM CDT THU JUL 10 2014 .UPDATE... ISSUED AT 1139 PM CDT THU JUL 10 2014 ONLY MINOR POP ADJUSTMENTS FOR THE NEXT FEW HOURS. WITH LACK OF INSTABILITY UNSURE HOW WESTERN CONVECTION WILL HOLD TOGETHER SO STUCK WITH CURRENT POPS. SOUTHERN CONVECTION SHOULD REMAIN CONFINED TO THE SE QUARTER OF THE FA GRADUALLY SHIFTING EAST TOWARDS MORNING. UPDATE ISSUED AT 931 PM CDT THU JUL 10 2014 INCREASED POPS ACROSS WEST CENTRAL MN FOR A COUPLE HOURS WHERE MORE CONCENTRATED SHOWERS EXIST. NO OTHER CHANGES MADE. UPDATE ISSUED AT 628 PM CDT THU JUL 10 2014 MAIN CHANGES WERE ADJUSTING POPS THROUGH MID EVENING. SHOWERS AND MAYBE EVENTUAL T CONFINED TO SOUTHERN THIRD OF FA WITH CURRENT SHORT WAVE PASSAGE. NORTHERN AREAS SEEING MAINLY CI OR CLEARING SO PULLED POPS AS RAIN CHANCES NOT EXPECTED UNTIL APPROACH OF CFP LATER TONIGHT. NO OTHER CHANGES. && .SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT) ISSUED AT 304 PM CDT THU JUL 10 2014 THUNDERSTORM CHANCES AND SEVERITY WILL BE THE MAIN FORECAST HEADACHE FOR THE PERIOD. A LEAD SHORTWAVE CURRENTLY MOVING THROUGH CENTRAL ND HAS BROUGHT PLENTY OF MID LEVEL CLOUDS AND SOME RADAR RETURNS...BUT THERE HAS NOT BEEN A LOT OF PRECIP ACTUALLY REACHING THE GROUND SO FAR. THERE HAS BEEN SOME GOOD LIFT AS THE SHORTWAVE TROUGH MOVES TOWARDS THE RED RIVER VALLEY...BUT CAPE VALUES SO FAR HAVE BEEN NOT VERY IMPRESSIVE...AROUND 500 J/KG AND BULK SHEAR VALUES ARE BETTER FURTHER SOUTH OVER SD. HOWEVER...MOISTURE TRANSPORT WILL CONTINUE TO INCREASE THIS EVENING AHEAD OF THE SFC TROUGH AXIS AS IT MOVES INTO THE CWA. THINK THAT THERE COULD BE SOME ACTIVITY IN OUR SOUTHERN COUNTIES AS THE LOW LEVEL JET STARTS TO CRANK UP...BEFORE THE SHORTWAVE MOVES WELL PAST US INTO WI. BUMPED UP POPS AND QPF...BUT LEFT OUT A MENTION OF SEVERE AT THIS POINT. THE MAIN UPPER TROUGH IS STILL OVER WESTERN CANADA...AND THAT WILL MOVE INTO MANITOBA TONIGHT. WITH THE STRONG JET CLOSE TO THE INTERNATIONAL BORDER...THERE COULD BE SOME STORMS ALONG THE COLD FRONT AS IT MOVES INTO OUR NORTHWESTERN COUNTIES LATER TONIGHT. AGAIN...NOT MUCH INSTABILITY AVAILABLE EVEN ELEVATED. WILL CONTINUE TO KEEP SOME POPS IN THE NORTH. THE COLD FRONT WILL MOVE INTO THE SOUTHEASTERN CWA DURING THE DAY TOMORROW AS THE NORTHERN BRANCH UPPER LOW HEADS EAST INTO ONTARIO. DEPENDING ON THE EXACT TIMING OF THE FRONT...THERE COULD BE A FAIR AMOUNT OF DESTABILIZATION IN OUR SOUTHEASTERN COUNTIES BEFORE THE FRONT MOVES THROUGH. IF NAM CAPE VALUES OF 3000 J/KG VERIFY ALONG THE GOOD CONVERGENCE ZONE WITH THE FRONTAL BOUNDARY...THERE COULD BE SOME STRONG TO SEVERE STORMS FRIDAY AFTERNOON BEFORE THE FRONT MOVES OFF TO THE SOUTHEAST. FRIDAY NIGHT SHOULD BE MUCH MORE QUIET AS THE FRONT MOVES OUT AND WEAK HIGH PRESSURE BUILDS INTO THE NORTHERN PLAINS. .LONG TERM...(SATURDAY THROUGH THURSDAY) ISSUED AT 304 PM CDT THU JUL 10 2014 SATURDAY AND SUNDAY...HEIGHTS WILL CONTINUE TO DECREASE AS REINFORCING SHORTWAVES DIG THE UPPER LOW DEEPER INTO SOUTH CENTRAL CANADA. THERE SHOULD BE ONE COLD FRONT MOVING IN FOR SATURDAY AFTERNOON AND NIGHT...AND ANOTHER STRONGER BOUNDARY LATE IN THE DAY ON SUNDAY. SFC WINDS WILL BE FROM THE WEST AHEAD OF THE FRONT ON SATURDAY...SO THERE WILL NOT BE A HUGE AMOUNT OF CONVERGENCE AND SFC BASED CAPE IS NOT VERY IMPRESSIVE. SUNDAY LOOKS EVEN MORE STABLE. WILL KEEP POPS IN THE 10 TO 40 PERCENT RANGE AS THESE REINFORCING BOUNDARIES COME DOWN. TEMPS WILL BE NEAR SEASONAL AVERAGES ON SATURDAY BUT ABOUND 5 TO 10 DEGREES COOLER ON SUNDAY. MONDAY...DYNAMIC MODELS REMAIN IN GOOD AGREEMENT THAT AN UNUSUALLY STRONG MID JULY UPPER LOW WILL DROP ACROSS THE WESTERN GREAT LAKES. WITH THE STRONG CYCLONIC FLOW...COLD AIR ALOFT AND TIME OF YEAR SHOWERS ARE LIKELY ESPECIALLY EAST OF THE RED RIVER. HAVE OPTED TO NOT INCLUDE THUNDER ATTM ALTHOUGH ITS POSSIBLE WITH THE SUB ZERO 700MB COLD POOL. WOULD DEPEND ON SOLAR AND FUTURE FORECASTS WILL RESOLVE THAT. CURRENT GUIDANCE SUGGEST RECORD LOW MAXIMUMS ACROSS OUR CWFA. TUESDAY...DEEP NORTH FLOW SURFACE AND ALOFT GRADUALLY RELAXES WITH ATTENDANT BRISK NORTH FLOW. QUITE COOL DESPITE INCREASED SOLAR AS HIGHER HEIGHTS/THICKNESSES SLOW TO MOVE IN BEHIND DEPARTING LOW. ANOTHER UNUSUALLY MID JULY DAY. OUTSIDE OF SOME LINGERING -RASH 00Z - 12Z TUESDAY EXPECT VERY LOW RISK OF PRECIPITATION. PLAN TO KEEP WITH CURRENT DRY FORECAST DURING THE DAY. WEDNESDAY AND THURSDAY SHOULD REMAIN PRECIPITATION FREE WITH EACH DAY A LITTLE WARMER. RETURN FLOW OUT OF COOL HIGH AND SLOWLY INCREASING THICKNESSES SUGGEST WARMING TO NEAR CLIMATOLOGICAL NORMAL LIKELY BY END OF PERIOD. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z FRIDAY NIGHT) ISSUED AT 1139 PM CDT THU JUL 10 2014 MAINTAIN VFR CONDITIONS. CONFINED T CHANCES TO DVL AND BJI. ELSEWHERE LACK OF INSTABILITY LIMITS CONFIDENCE ON PCPN POTENTIAL. FRONT WILL SHIFT EAST ACROSS THE FA FROM LATE TONIGHT THROUGH TOMORROW. WILL BE LOOKING AT WSHFT AND CLEARING IN THE WAKE OF FROPA. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...NONE. MN...NONE. && UPDATE...VOELKER SHORT TERM...JR LONG TERM...JR/EWENS AVIATION...VOELKER
