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.
Event Narrative Brief touchdown in an unpopulated section of Ham Lake.
