Episode Narrative: During the afternoon of August 19th, a large area of generally moderate to heavy showers occurred across most of south central and east central Minnesota. The area had very few lightning strikes, and most of the shower activity was racing northward at 40 to 50 mph. An area of low pressure developed across east central Minnesota during the afternoon, and began to intensify prior to the tornado development. Several weak areas of intense showers moved northward across the Twin Cities metro area. Low level humidity levels were very high, which provided a very low cloud base around 1000'. Although weak circulations were noted on radar, not until the surface low intensified and allowed for an overall increase in the surface inflow, did tornadoes develop. Most of the tornadoes were weak. During the afternoon of August 19th, a large area of generally moderate to heavy showers occurred across most of south central and east central Minnesota. Event Narrative: A National Weather Service Storm Survey determined that an EF-1 torando tracked from near U.S. Highway 61 and 122nd Street South, to near Lehigh Avenue South on the far southeast periphery of Cottage Grove, Minnesota. ||The local law enforcement officials observed the tornado as it moved through the residential area. The majority of the damage occurred in the 11700 block of Lockridge Avenue. This is where the tornado was rated an EF-1 based on large trees uprooted and winds estimated near 90 mph. Some structural damage occurred in the residential area where a garage door collapsed inward, wooden fences blown down, and a metal shed blown across the street. Scattered trees and large limbs were downed as a tornado moved from southeast to northwest across western sections of Marine on St. Croix. A roof was completely torn off a farm house, and several large sheds and outbuildings were destroyed. The tornado tracked through corn fields, from south-southeast to the north-northwest. A local trained spotter reported minor flooding along Interstate 494, at Lyndale Avenue with local construction along the interstate. In addition, Normandale service road had ponding of water between Interstate 494 and West 84th Street. About two dozen trees were blown down in the neighborhood just northeast of Highway 252 and 85th Avenue. The trees were all blown down from east to west and scattered across the neighborhood. A NWS Skywarn Instructor, who is a broadcast meteorologist, surveyed an area of that was associated with straight-line wind damage that occurred in a new subdivision in Stonemill Farms in Woodbury, Minnesota. The damage was mainly to trees blown down and some siding blown off homes around Aster Lane, Windmill Curve, Walden Drive and Sawmill Curve. A National Weather Service Storm Survey determined that an EF-0 Tornado tracked from near East 53rd Street and Park Avenue in South Minneapolis, to near the Convention Center in Downtown Minneapolis. Most of the damage was confined to large trees blown down, or damage to roofs and buildings/houses as the trees fell on the structures. Most of the eyewitnesses reported swirling above, and strong winds at the surface. At the widest and strongest portion of the tornado, wind speeds were estimated between 75 and 85 mph. Brief touchdown in an unpopulated section of Ham Lake.
