The other two years on the chart, 2014 and 2016, are pretty close to each other. The blue shade is the range of where the lowest and highest has been since keeping records in Waterloo.

Sunday Flooding Update

July 23, 2017

There still are flood warnings in effect for various counties across the viewing area.  Remember, avoid driving or walking through flooded roadways.

 

The Volga River at Wadena and Volga continues to fall, after cresting at moderate flood stage at both towns.

The Volga River at Littleport has gone up and down a few inches over the last 24 hours and is still at major flood stage.  It appears the river at Volga has reached its crest, and will be on a steady fall.

Volga at Littleport

More good news to pass along…the Maquoketa River at Manchester reached its crest, well below what was originally forecast Saturday.  The river reached minor flood stage, and crested at 15.31 feet just after midnight Sunday, and is now back below flood stage.

The Turkey River at Elkader is now below flood stage, while downstream at Garber, the River is still at moderate flood stage and will begin falling tonight.

Wapsipinicon River at Tripoli remains at minor flood stage, but as you see from the hydrograph below, the river is steadily falling.

Downstream in Independence, the Wapsi River has risen very quickly, and is now in major flood stage.  The river is forecast to crest late tonight, and be back below flood stage sometime on Wednesday.

The Wapsi at Anamosa will crest a couple days later, right on the cusp of major flood stage.

Moderate to major flooding on local rivers

July 22, 2017

Due to the recent heavy rainfall between 2 and 10 inches across northern parts of the KWWL viewing area, local rivers are experiencing quick rises, leading to moderate to major flooding.

The Volga River at Wadena, Volga and Littleport is experiencing major flooding as of Saturday afternoon, forcing evacuations in Volga.  The Turkey River at Elkader and Garber remains at minor to moderate flood stage, and is forecast to continue to rise through Sunday afternoon.

The Wapsipinicon River near Tripoli is experiencing minor flooding (there is no forecast point for the river near Tripoli).  However, downstream in Independence, the river is expected to rise rapidly Saturday night into Sunday.  The same can be said for the Maquoketa River at Manchester.

No flooding is currently forecast on any part of the Cedar River.

Below you can see the hydrographs that are put out by National Weather Service hydrologists.  Please stay up to date with the latest information.  You can always check the latest levels by clicking this link.

Temperature Drop Due to Storm

July 18, 2017

The high temperature in Cedar Rapids today was 89° at 4:52 pm with a heat index of 100°. An area of rain/storms was moving northeast and approaching the city around 5:30 PM. The downdraft in the storm was pulling cooler air toward the ground. The rain cooled air in the storm resulted in a temperature drop of 17° in less than one hour.  Officially 0.08″ of rain fell at the Eastern Iowa Airport. Farther south into Johnson County, rain amounts were around 1.25″ in one hour.

90 Degree Days

July 18, 2017

Hot and very humid weather is expected through Saturday. Some locations will top 90 degrees a few times this week. I took a look back at how many 90 degrees we have had so far this year and compare that to previous years. At a quick glance, 2012 was hot through the middle of July.

Through July 18th, Waterloo has reached 90 or warmer nine times while Dubuque has only done it two times. Cedar Rapids came close today with a high of 89….so far this year it is eitght days. Today was another day of 90+ for Iowa City with a high of 92. That now takes the number of days of 90 or warmer to 18.
