NWS team surveys storm damage; blustery Friday, nicer this weekend

The Twin Cities office of the National Weather Service has set up a page where they will post information about Thursday’s tornadoes:

As of 800 AM, Friday, September 21, 2018, damage survey teams from the NWS were in the process of surveying areas of damage across the area impacted by the storms.

Radar data and spotter reports indicated that a few tornadoes likely occurred with the storms, and survey teams will make the final determination as to if, when, and where tornadoes occurred. This page will be updated as new information is received.

Here’s a preliminary listing of tornado reports posted by the NWS Storm Prediction Center:

Times listed are in Universal time, which is five hours ahead of CDT.  For instance, 2252 converts to 1752, which is 5:52 p.m. CDT.

This Thursday evening tornado video from Granada, Minnesota is impressive:

There was also wind damage in Waterville, Minn., in Le Sueur County, that will be surveyed by the NWS Friday.

Most of the Twin Cities metro area saw strong straight-line winds and torrential rains as the storms moved through, and there were many reports of street flooding:

Thankfully, no fatalities have been reported from Thursday’s storms.

By the way, a new rainfall record was set for Sept. 20 in the Twin Cities:
