What happened
The episode as NWS DLH wrote it up.
Very little rain fell across the Arrowhead of Minnesota during the month of April. Precipitation totals were only 10 to 25 percent of normal for the month. This lack of rain allowed for severe (D2) drought conditions to develop by the end of the month across Cook, Lake, and far southeastern St. Louis counties, according to the U.S. Drought Monitor.

A WEAK AND VERY DRY COLD FRONT WILL HAVE MOVED BEYOND OUR AREA THIS EVENING. HIGH PRESSURE FOLLOWING THE FRONT...NOW OVER THE DAKOTAS...WILL MOVE NORTH THROUGH AND BEYOND THE AREA...CAUSING WINDS TO SHIFT TO ONSHORE SHORTLY AFTER MIDNIGHT...AND INCREASE. DEVELOPING LOW PRESSURE OVER COLORADO WILL MOVE ALONG THE TROUGH THURSDAY AND PUSH IT BACK THROUGH OUR AREA THURSDAY NIGHT OR FRIDAY. SHALLOW COLD MARITIME AIR FROM THE LAKE WILL RESIST THE NORTHWARD PROGRESS OF THE TROUGH MORE THAN THE MODELS SUSPECT. THE DENSITY GRADIENTS WILL ACCELERATE THE ONSHORE FLOW BOTH THURSDAY AND FRIDAY...THE NAM BRINGS SURFACE WINDS TO 30 KTS OR SO. WE BACKED OFF ON SUCH WINDS UNTIL WE SEE A FEW MORE RUNS. WHAT IS APPARENT IS A STRONG TEMPERATURE CONTRAST BETWEEN THE WARM FLOW OVER THE INLAND COUNTIES OF NORTHWEST WISCONSIN AND UPPER ST CROIX VALLEY AND THE COLD MARITIME AIR OVER AREAS ADJACENT TO LAKE SUPERIOR. AT THIS TIME...THE FIRST DEEP LOW WILL MOVE NORTHWARD THROUGH WESTERN MN FRIDAY AND DRAG A FRONT THROUGH FRIDAY NIGHT OR EARLY SATURDAY. THE NAM AND GFS BRING MOST ASSOCIATED JUST BEHIND THE LOW...INTO THE RED RIVER VALLEY...WHILE THE EUROPEAN BRINGS MOISTURE FROM THE GULF...AHEAD OF THE FRONT...OVER OUR AREA. THE EUROPEAN POSITION DOES NOT MAKE MUCH SENSE...SINCE THE FRONT IS STRONG AND THE NORMAL COMPONENT OF THE UPPER FLOW IS LESS THAN THE SPEED OF THE FRONTAL MOVEMENT...SUGGESTING UPSLOPE OVER THE COLD SURFACE AND PRECIPITATION NEAR...AND OVERRUNNING THE COLD AIR... WEST OF THE FRONT. THE NAM AND GFS DRIFT THE WHOLE SYSTEM EAST DEVELOPING ANOTHER STRONG WAVE...WITH GENEROUS PRECIPITATION ALONG THE NEGATIVELY TILTED FRONT FROM CENTRAL WI EASTWARD THROUGH CENTRAL LOWER MI SATURDAY AND SATURDAY EVENING. WE WENT WITH THAT DOMESTIC SCENARIO. THE TENDENCY FOR DRY WEDGES TO TUCK THEMSELVES NEAR OR JUST BEHIND STRONG FRONTS REINFORCES OUR CONCLUSIONS. EXTENDED...SATURDAY NIGHT THROUGH TUESDAY. THE CUT OFF MID LVL LOW WILL LIFT NE FROM THE UPPER MIDWEST INTO ONTARIO SAT NIGHT....CONTINUING INTO THE HUDSON BAY REGION ON SUNDAY. TIMING THE BACK EDGE OF THE RA SHOWERS ASSOCIATED WITH THE LOW IS STILL SOMEWHAT UNCERTAIN...BUT BETTER AGREEMENT IN THE GFS/NAM THAT THE DRY AIR MOVES INTO THE FA BRINGING DECREASING CLOUDS THROUGH THE DAY SUNDAY. AS THE LOW DEPARTS THE FA BECOMES SITUATED UNDER A 50 KT ZONAL FLOW WITH SEVERAL EMBEDDED SHORT WAVES THAT MAY BRING A ISOLATED SHOWER OR TWO ON MONDAY. FROM HERE THERE ARE LARGE MDL DIFFERENCES IN THE TIMING OF A LONG WAVE TROUGH THAT MAKES LANDFALL ON THE PACIFIC COAST MONDAY AND DEEPENS INTO A CLOSED LOW AS IT TRACKS EAST OVER THE ROCKIES THROUGH MID-WEEK.
