A Canadian cold front signalling the end of summer moved across Minnesota on Wednesday, September 21st. Out ahead of the front temperatures soared into the upper 80's to low 90's. Skies to south of the front were mostly clear and provided a good view of the bubbling thunderheads forming to the northwest of the Twin Cities. During the late afternoon and evening hours, a series of supercell thunderstorms developed ahead of the advancing cold front in an environment favorable for severe weather, producing tornadoes, large hail, damaging straight-line winds, and periods of heavy rainfall.
The first thunderstorms developed just east of St. Cloud during the late afternoon hours of September 21. The storms grew stronger as they moved to the east and developed to the west and southwest. Numerous homes and businesses sustained structural damage, while trees and power lines were downed across several communities, resulting in widespread power outages that affected thousands of residents. In addition to the tornadoes, powerful straight-line winds associated with rear-flank downdrafts and downbursts caused extensive damage throughout portions of the metro, particularly in areas such as Andover, Coon Rapids, and Blaine. The storms also generated large hail, with hailstones reaching approximately 2.5 inches in diameter in Andover. Heavy rainfall accompanying the storms led to localized flash flooding, especially in Brooklyn Park and other northern Twin Cities communities, where several inches of rain fell in a short period of time. The combination of tornadoes, damaging winds, giant hail, flooding, and widespread power outages made this one of the most impactful severe weather events to affect the region during 2005.
Four tornadoes were confirmed across Minnesota during the event; the most notable tornado was the F2 tornado that damaged portions of Blaine and Coon Rapids, Minnesota. The tornado touched down at approximately 7:17-7:21 pm CDT with estimated peak winds of 113-157 mph. The path length was about 2 miles with a max width of 50 yards with roughly one person injured during this tornado. Major damage was sustained just south of Madison Elementary School; otherwise, most damage was sustained by rear flanking downdrafts that blew off a roof and damaged at least 100 trees in the Bunker Hills Golf Course. Approximately 10 homes were severely damaged while about 20 homes were significantly damaged. This was the fourth tornado to touch down during this event. There were three other tornadoes that touched down briefly as well, though they were all classified as F0. The first tornado touched down 3 miles south of Atwater, MN at approximately 6:22 pm CDT with estimated winds of less than 73 mph. The path length was 0.1 miles with a maximum width of 20 yards. The second tornado touched down in Brooklyn Park, MN at 7:07 pm CDT with estimated winds of less than 73 mph. The path length was about 0.3 miles with a maximum width of 30 yards. The majority of the damage associated with this tornado was caused by rear flanking downdrafts that led to gas leaks, downed trees, and power lines. The third tornado touched down in Andover, MN at 7:16 pm CDT with estimated winds of less than 73 mph. The path length was 0.3 miles with a width of about 25 yards. For this tornado, once again, the most notable damage was associated with the rear flanking downdraft and straight-line winds that caused damage to houses, garages, and large trees. A canoe was thrown 2 blocks away from the original starting point as well. A 45-year-old man lost his life in northern Minneapolis after a tree branch had fallen on him. This was the only fatality from this event.
Ten school districts cancelled class on Thursday including Anoka-Hennepin, Osseo, Robbinsdale, Fridley, Columbia Heights, Mounds View, and Brooklyn Center. In addition, North Hennepin Community College was closed along with private schools and Anoka County libraries. 160,000 people were without power by 10:30 pm on the night of the storm.
Heavy rains fell with several waves of storms across the north metro. The heaviest rain began around 6pm and ended around midnight. Street flooding was reported in Fridley, Spring Lake Park, Coon Rapids, Blaine, Champlin and Shoreview. Some amounts include..
Location Amount Fridley 3.29 North St. Paul 3.11 White Bear Township 3.10 Brooklyn Park 3.06 Maplewood 2.92 Crystal Airport 2.38 New Hope 2.17 St. Paul 2.13 Stillwater 2.02 U of M St. Paul 1.87 Golden Valley 1.61 St. Paul Airport 1.54 Minneapolis L/D #1 1.45 Forest Lake 1.07 Minneapolis/St Paul Airport .21 Chanhassen .09

PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 910 PM CDT FRI SEP 23 2005 ...MORE RESULTS FROM THE DAMAGE SURVEY FOR TORNADOES AND SEVERE THUNDERSTORMS IN THE NORTHERN TWIN CITIES METRO AREA ON SEPTEMBER 21ST... STORM DAMAGE WAS SURVEYED ACROSS PORTIONS OF THE NORTHERN METRO FOR THE SECOND CONSECUTIVE DAY. YESTERDAY IT WAS FOUND THAT TWO TORNADOES PLUS WIDESPREAD DOWNBURST DAMAGE HIT ANDOVER...COON RAPIDS AND BLAINE IN ANOKA COUNTY. TODAYS SURVEY COVERED NORTHERN HENNEPIN AND SOUTHERN ANOKA COUNTIES. THE STORMS MOVED EAST-SOUTHEAST. THE VAST MAJORITY OF DAMAGE IN NORTHERN HENNEPIN COUNTY WAS DUE TO DOWNBURST WINDS...MOSTLY FROM THE REAR FLANK DOWNDRAFT SWINGING AROUND THE SOUTH AND WEST SIDES OF THE MESOCYCLONE. A SMALL AND VERY BRIEF F-0 TORNADO WAS ALSO DISCOVERED TO HAVE TOUCHED DOWN IN THE FAR NORTHEAST CORNER OF BROOKLYN PARK...BUT THE TORNADO DAMAGE PALED IN COMPARISON TO THE DAMAGE CAUSED BY THE DOWNBURST. THE DOWNBURST WINDS WERE STRONGER AND MORE WIDESPREAD THAN THE WINDS OF THE F-0 TORNADO. IN FACT...THE DOWNBURST PRODUCED F-1 DAMAGE ACROSS MUCH OF NORTHERN HENNEPIN COUNTY...WITH A FEW ROOFS BLOWN OFF IN BROOKLYN PARK. THOUSANDS OF TREES WERE TOPPLED OR SNAPPED. THE TORNADO DID NOT CROSS THE MISSISSIPPI RIVER. THE STORM MOVED FROM NORTHERN HENNEPIN COUNTY...AND INTO SOUTHERN ANOKA COUNTY. FRIDLEY WAS ESPECIALLY HARD HIT. THE CHARACTER OF THE STORM ALSO CHANGED. THERE WAS SOME SPORADIC DOWNBURST DAMAGE IN SOUTHERN FRIDLEY FROM THE REAR FLANK DOWNDRAFT...BUT THE MESOCYCLONE ITSELF...OR THE CENTER OF THE ROTATING STORM...BEGAN PRODUCING DAMAGE ON ALL SIDES. PERHAPS THE HARDEST HIT AREA WAS THE AREA BETWEEN FRIDLEY HIGH SCHOOL AND UNIVERSITY AVENUE. NUMEROUS TREES WERE KNOCKED DOWN IN ALL DIRECTIONS...WITH MANY LANDING ON HOUSES AND VEHICLES. ONE EYEWITNESS DESCRIBED THAT TREES WERE FIRST KNOCKED DOWN TOWARD THE SOUTH. THE INTENSE WIND CONTINUED BUT BEGAN CHANGING DIRECTIONS. THEN WHAT SEEMED LIKE THREE OR FOUR MINUTES LATER...TREES WERE BEING KNOCKED DOWN TOWARD THE NORTHEAST. THE INTENSE WIND CONTINUED...STILL GRADUALLY CHANGING DIRECTION. FINALLY...WHAT SEEMED LIKE SEVERAL MINUTES LATER...TREES WERE ONCE AGAIN KNOCKED DOWN TOWARD THE SOUTH. THIS ACCOUNT IS CONSISTENT WITH THE MESOCYCLONE MOVING OVERHEAD. THERE WAS VERY LITTLE MAJOR WIND DAMAGE TO ANY OF THE HOUSES. INSTEAD...THE DAMAGE TO HOUSES WAS TYPICALLY CAUSED BY FALLING TREES. THIS SUGGESTS THAT WINDS WERE PROBABLY FROM 60 TO 70 MPH...BUT THAT THE WINDS WERE SUSTAINED FOR MANY MINUTES. ONE INTERESTING NOTE IS THAT THE TREES SEEMED TO FALL DOWN IN SLOW MOTION. FURTHERMORE...THERE WAS NO INDICATION OF ANY DISTINCT OR CONCENTRATED DAMAGE PATH OF PARTICULARLY INTENSE DAMAGE. INSTEAD...THE VARYING DIRECTIONS OF TOPPLED TREES WAS EXHIBITED OVER A DIAMETER OF ONE TO TWO MILES. THE ROTATING STORM MOVED INTO RAMSEY COUNTY. NUMEROUS TREES IN NEW BRIGHTON...JUST NORTH OF 694 AND SILVER LAKE ROAD...SHOWED THE SAME TYPE OF BROAD ROTATION DAMAGE PATTERN AS IN FRIDLEY. MANY TREES WERE DOWNED FROM NEW BRIGHTON INTO SHOREVIEW. A SUMMARY OF THE BLAINE AND ANDOVER DAMAGE SURVEYS FOLLOWS... THE TEAM DETERMINED THAT A TORNADO TOUCHED DOWN IN THE EXTREME EASTERN PART OF COON RAPIDS...MOVED INTO BLAINE...BEFORE DISSIPATING JUST WEST OF THE NATIONAL SPORTS CENTER. IT WAS ON THE GROUND FOR TWO MILES...TRACKED EAST-SOUTHEAST...WAS AN F-2...AND HAD A MAXIMUM WIDTH OF 50 YARDS. THE VAST MAJORITY OF DAMAGE IN ANDOVER WAS DUE TO REAR FLANK DOWNDRAFT WINDS ROTATING AROUND A MESOCYCLONE. IN FACT...THE DOWNBURST PRODUCED F-1 DAMAGE IN ANDOVER...ACROSS A LARGE AREA...WHEREAS THE ANDOVER TORNADO WAS AN F-0 OVER A VERY SMALL AREA. THE ANDOVER TORNADO HAD A MAXIMUM WIDTH OF 25 YARDS...WITH A PATH LENGTH OF 0.3 MILE. THE TORNADO TOUCHDOWN WAS JUST WEST OF THE INTERSECTION OF 142ND AVENUE NORTHWEST AND 143RD AVENUE NORTHWEST. PUBLIC INFORMATION STATEMENT...REVISED NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 814 PM CDT THU SEP 22 2005 ...EARLY RESULTS FROM DAMAGE SURVEY TEAM REGARDING POSSIBLE TORNADOES IN NORTHERN TWIN CITIES METRO AREA ON SEPTEMBER 21ST... THE TEAM HAS DETERMINED THAT A TORNADO TOUCHED DOWN IN THE EXTREME EASTERN PART OF COON RAPIDS...MOVED INTO BLAINE...BEFORE DISSIPATING JUST WEST OF THE NATIONAL SPORTS CENTER. THE TORNADO WAS ON THE GROUND FOR TWO MILES...TRACKED EAST SOUTHEAST...WAS AN F2...AND HAD A MAXIMUM WIDTH OF 50 YARDS... THE STORM DAMAGE TEAM HAD DETERMINE THAT THE TORNADO THAT OCCURRED IN ANDOVER WAS AN F0...AND HAD A MAXIMUM WIDTH OF 25 YARDS...AND THE PATH LENGTH WAS 3 TENTHS OF A MILE. THE TORNADO TOUCHDOWN BRIEFLY AT THE INTERSECTION OF 142 AVE NW AND 143RD LANE NW. THE VAST AMOUNT OF THE DAMAGE WAS CONTRIBUTE TO THE REAR FLANK DOWNDRAFT IN THE WAKE OF THE TORNADO WHICH PRODUCE WIND GUSTS BETWEEN 80 AND 100 MPH. EARLIER THE TEAM WAS IN FRIDLEY...ADDITIONAL STUDY WILL BE NEEDED TO DETERMINE WHETHER THE FRIDLEY DAMAGE WAS TORNADIC. ADDITIONAL INFORMATION WILL BE AVAILABLE THIS EVENING.
