A severe thunderstorm moved across Tama County with heavy rain, lightning, gusty winds and large hail. All the reports and photos we have gotten this evening were from Traer.

Here is the warning issued at 4:34 PM…

Here is a look at the radar…

Golf ball size or maybe a little large were some of the reports. There might be some damage to vehicles and the roof of you home or business. You might want to have them checked out to make sure there was no damage.

Saturday Weather Photos

June 2, 2018

Countless viewers had their cameras ready and snapped photos of weather wide variety of weather we had across eastern Iowa Saturday.

The day started off with rain and a few thunderstorms.  Behind the shield of rain, a “wake low” formed, which produced 50 to 80+ mph winds, in the wake of the rain.  Hampton, Iowa had an 87 mph wind gust.  The gusty wind did cause some tree damage in Aplington and Parkersburg.

Another round of rain and storms moved through portions of northern Iowa late in the afternoon and early evening.  Many viewers caught rainbows shortly after the rain and storms.

Tim Schueller – New Hampton

 

Heather Hageman – Farmersburg

 

Nichole LaMarsh – Nashua

 

Rod McLane – Guttenberg

 

Brenda Elsamiller – Owelwein

 

The line of storms went on to produce some picturesque scenes of shelf clouds rolling in.  This is a sign of gusty winds out ahead of the line of storms.  Some of the low-hanging clouds you see are harmless, known as “scud.”

Warm May…Saturday Rain…Hot and Humid Again

June 1, 2018

It was a warm May.  The average temperatures for the month put most of the locations in top 5 warmest May on record.

We catch a nice break from the heat and humidity for the weekend as a cold front pushes through the state. A few showers and storms are possible Saturday…mainly in the afternoon. By the end of next week it will be hot and humid again. Next weekend looks hot and humid. Here is the temperature outlook for June 9-15.

Showers and storms to our west will weaken overnight. If any of the rain makes into eastern Iowa by morning it will be very light.

The front producing the storms this evening will bring a few showers/storms to eastern Iowa Saturday afternoon. No severe weather is expected. The showers will be scattered. The map shows the position of the front Friday evening.

Ending our Stretch of 90+

May 29, 2018

After today, cooler air tracks into eastern Iowa. But, not before this heat wave goes down in the history books. Daily record highs were broken across the Big Four over the Memorial Day weekend.

This was the longest stretch of 90°+ during the month of May in Waterloo since 1934. Dust Bowl, anyone? Also known as the “Dirty Thirties”, several rounds of drought plagued the United States during the 1930s.

In 1934, the Waterloo area saw four days of 90°+ that May, like we did in May 2018.

Dubuque saw two days in a row of 90°+ this month while Cedar Rapids and Iowa City both also saw four days of 90°+ for May 2018.

Normal highs this time of year run in the 70s. Cooler air is on the way starting midweek.

Record Heat

May 27, 2018

No doubt about it, it’s been an unusually warm Memorial Day weekend across eastern Iowa.  Here are the high temperatures from across the area:

Waterloo, Dubuque, Cedar Rapids and Iowa City all broke records.  Some of those records were more than 100 years old!

These temperatures are unusual for May, but to put this into perspective, it hasn’t been this warm in our neck of the woods since 2012 and 2013.  Last time temperatures were this warm:

Waterloo: September 10, 2013 97°
Dubuque: July 25, 2012 101°
Cedar Rapids: September 10, 2013 97°
Iowa City: September 10, 2013 99°

The heat is not going to let up as we head into the Memorial Day holiday itself, with more record heat likely.  Fortunately, the humidity levels won’t be terrible.  If this were toward the middle of summer where we had corn at its peak, this would be more unbearable for us.

Eastern Iowa Tornadoes – May 25, 2008

May 25, 2018

May 25, 2008 was an active day for severe weather across eastern Iowa, with six tornadoes being confirmed across the KWWL viewing area.  Of note was the EF-5 tornado impacting Parkersburg, New Hartford and Dunkerton with estimated peak wind speeds up to 205 mph(to watch our special report “Tornado Turnaround”, click here), and the EF-3 tornado near Fairbank and Hazleton, with peak wind speeds up to 160 mph.

There was also an EF-1 tornado south of Lamont in Buchanan County, as well as an EF-1 south of Petersburg in Dubuque County.  Another EF-1 touched down near Interstate 80 in western Iowa County, fortunately not impacting many people.  And finally, an EF-0 was reported north of North Liberty.  To read the full assessments from the NWS Quad Cities, click here.

  1.  The tornado touched down 2 miles south of Aplington, before growing to 3/4 of a mile wide as it moved to the south side of Parkersburg.  300 homes and businesses were destroyed.  Seven people were killed, with many others injured.  From there, the tornado went down Highway 57 and tore through the northern part of New Hartford, where it killed two people, and damaged and destroyed many homes.  The Sinclair Elevator and the Oak Hill Cemetery took a direct hit.  Read the full assessment from NWS Des Moines here.
  2. The EF-2 tornado in Buchanan County touched down near Fairbank.  The tornado was 0.7 miles wide and was on the ground for 32.4 miles.  Three homes were destroyed, with many others damaged, along with several downed trees and power lines.  On the south side of Hazleton, many mobile homes were destroyed.  Three people were injured
  3. EF-1 tornado south of Lemont was about 100 yards wide with an estimated peak wind speed of 90 mph, and was on the ground for 2 miles.  There were many outbuildings and trees that were damaged.  No injuries or deaths were reported.
  4. An EF-1 was confirmed south of Petersburg in Delaware county.  The tornado was 250 yards wide with estimated wind speeds of 90 mph, and was on the ground for 7.75 miles.  Trees and outbuildings were damaged, along with more than 1,000 trees destroyed in New Wine Park.  No injuries/deaths were reported.
  5. An EF-0 was reported north of North Liberty in Johnson County. Estimated wind speeds were 85 mph, and it was 100 yards wide with a path of 0.1 miles.  Many trees were uprooted, and several homes were damaged.
  6. And EF-1 tornado was reported near Interstate 80 in Iowa County.  Estimated wind speeds were 90 mph, and it was 250 yard wide and was on the ground for 6 miles.  No injuries or fatalities were reported.  A grain bin near Victor was blown over, and a tree fell on a mobile home.  Many machine sheds were also damaged.

Here is a full list of the storm reports, mesoscale discussion, watches and outlooks for the nation that day.

 

The Enhanced Fujita scale is used to estimate wind speed based on the damage from the tornado.  They are not measured wind speeds.
