- July 15, 1980 Southern Twin Cities and Western Wisconsin Windstorm - NWS MSP WSR-57 Radar
- Date posted
- 4 years ago
- Description
- A devastating windstorm on July 15, 1980 moved across the southern suburbs of Minneapolis-St. Paul and into western Wisconsin, where it intensified and produced widespread severe damage. It was Wisconsin's costliest storm up to that time. There were four fatalities: one in Minnesota and three in Wisconsin. Radar film from the NWS WSR-57 at the MSP International Airport was recently discovered and digitized.
Two loops and several still images are shown in this clip along with some explanations. The first loop, from 00:19 to 00:44, shows the broader picture. The second loop is shown from 1:44 to 2:13 and is zoomed in. There is no audio. The radar loops are shown from 11:51 a.m. to 10:34 p.m. CDT (in UTC, 1651z to 0334z). Eau Claire is about 85 miles east of MSP. When not zoomed in, the outer circle is 290 miles (250 nautical miles) from the MSP radar (brighter range rings are spaced at 58 miles). The zoomed in images and loops have the thicker gray circles at 58 and 116 mile...

- Description
- This one hour loop (from 405 PM to 505 PM on Wednesday, June 28, 2017) shows 1-minute satellite imagery from the GOES-16 satellite, encompassing the time period during which a tornadic supercell impacted portions of Pierce County, Wisconsin. he tornado occurred during a portion of this time period, roughly during the middle portion of the loop. The top image shows the storm from the satellite's visible channel, and the bottom image shows it from an infrared window channel. Since the satellite is in orbit above the equator, the combination of the storm's height and the curvature of the Earth result in parallax, which causes the storm to appear slightly north of its actual location. Meteorologists take this effect into account when evaluating satellite data in conjunction with radar and other data sources.

- MSP WSR-57 Radar from April 30, 1967
- Date posted
- 7 years ago
- Description
- Severe thunderstorms and a series of tornadoes impacted Minnesota and Iowa on 4/30/1967, with 13 deaths in Minnesota (there were no tornado deaths in other states that day). Residents refer to it as "Black Sunday." This video is an animation of individual 35 mm frames taken off of the then US Weather Bureau's WSR-57 radar in Minneapolis. The bright rings represent intervals of 50 nautical miles (58 statute miles), with the most distant ring having a radius of 250 nautical miles (290 statute miles). The radar was located at MSP International Airport and in use until 1996.
The tornadoes in MN and IA occurred to the southwest, south and southeast of MSP from 1550 to 2010 CST, roughly during the time from :04 to :12 seconds in the video. The radar operator on this day appears to have not applied any attenuation to the signal, resulting in most echoes being bright white. Therefore it is not easy to see any meaningful shapes such as hook echoes. Still, the overall pattern is...
