Lingering showers today, but nicer this weekend; update on Iowa tornadoes

Here’s a look at one of the tornadoes that touched down in central Iowa on Thursday:

According to Iowa Public Radio, no serious injuries or fatalities have been reported from Thursday’s tornadoes:

Gov. Kim Reynolds plans to visit the central Iowa cities of Bondurant, Pella, and Marshalltown Friday. All three communities were hit by tornadoes late Thursday afternoon.

As of Thursday night, no deaths or serious injuries had been reported, but there was a lot of damage.

In Marshalltown, a large twister heavily damaged several buildings downtown, and knocked the spire off the county courthouse. Also, the Lennox manufacturing plant was damaged, as were many other buildings in the area.

The Storm Prediction Center of the National Weather Service has this plot of all the Thursday tornado reports:

All times listed are in Universal time, which is five hours ahead of Central Daylight Time. For example, a time of 2010 is 2010 minus 5 hours or 1510, which is 3:10 p.m. CDT.

There can be multiple reports of the same tornado, so the final tornado tally is yet to be determined.

The Des Moines, Iowa office of the NWS will be sending crews out today to survey the damage:

Saturday should be dry for most of us, but northeastern Minnesota could see a passing shower.

Updated weather information can be heard on the Minnesota Public Radio Network, and updates are also posted on the MPR News live weather blog.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows that parts of Minnesota could see some showers late Tuesday into Wednesday:

There will be a lot of 70s on Saturday too, with a few spots from the Twin Cities metro area to southeastern Minnesota touching 80:
