A strong low pressure system moved through the region and produced torrential rains, along with several generally small tornadoes on August 16 and 17, 2017.
The rains came in multiple waves, with the first advancing across southern and eastern portions of Minnesota during the early morning hours on the 16th, resulting in up to an inch of rainfall in some areas. The main event, however, unfolded during the afternoon and evening hours, as storm cells blossomed, intensified, and trudged northward and northwestward across southern and central Minnesota. Some of the stronger cells produced brief tornadoes from near Mankato to about 50 miles south and west of the Twin Cities. With these storms and others in their vicinity, the rains came down hard, often producing up to two inches in 30-45 minutes and causing minor flooding. The tornado threat calmed down as night fell, but the heavy rains continued and eventually stalled out over portions of southwestern through and Minnesota, persisting for several hours into the 17th before weakening and moving away.
This was the most widespread and intense rainfall event of the year (to date) in Minnesota, with 1-2 inch totals covering approximately 50,000 square miles, or about 60% of the state. Totals of greater than three inches were concentrated in a multi-county area in western and central Minnesota, generally centered on the Minnesota River. The largest official rainfall reports came from Redwood Falls, where the airport recorded 9.45 inches, and a volunteer with the National Weather Service's cooperative observer program reported 8.12 inches-- both in 24 hours. These are the largest official 24-hour precipitation totals in Minnesota since June 20th, 2012, when Two Harbors reported 10.45 inches during the worst flood in that area's recorded history.
Fortunately, the tornadoes were short-lived and relatively weak. Of the eight confirmed by the National Weather Service in Chanhassen, seven were rated at EF-0. The lone EF-1 tornado damaged a farmstead near the Nicollet-Sibley county border, in the township of New Sweden.
One unusual aspect of this event was its noticeable lack of thunder. Very little lightning was reported, despite a swarming, thunderstorm-like appearance on radar. Although scientists have not concluded exactly what causes storms to electrify, they have observed that ice crystals, hail, and other frozen objects must be abundant in clouds for lightning to be present. In the case of this storm event, the clouds remained both too shallow and too warm to generate large amounts of cloud-ice, the lack of which may have prevented the "charge separation" required to create an electrical field within the storm environment. Although rainy days without lightning and thunder are quite common in Minnesota, intense rainfall events without lightning and thunder are not. Such conditions are more common in tropical weather systems, which contain massive amounts of heat, and therefore produce little or no cloud-ice and little or no lightning.
Below is a list of rainfall reports gathered by the National Weather Service.
