Summer Heat Rolls On

We’ve got one more day in our latest heat wave.  Monday’s temperatures will be in the middle 80s in northern Iowa, where they are closer to the cold front.

Farther south, temperatures will be in the lower to middle 90s, with Heat Index values 100° to 105°+ at times.

Warm May…Saturday Rain…Hot and Humid Again

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+

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

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.

Coldest April on Record

April 2018 goes into the record books as the coldest on record at Waterloo. As of yesterday, the average monthly temperature at Waterloo was 37.1° . Today’s numbers will push them up a bit. Here are the 10 coldest April’s in Waterloo.

Dubuque was also the coldest on record. The chart below is for Dubuque.

Cedar Rapids is no stranger to this record cold April either. Here are the number for Cedar Rapids.

Much of the Iowa and areas to the north had temperatures below normal in April.

This map below is broken up by climate districts. All of the districts with the number 126 in them represents the coldest April in those locations. One represents the hottest and 126 is the coldest.

Colder than… Alaska

We have said it before and are saying it again… it has been a cold start to spring here in eastern Iowa. In fact, through the first half of April, all of the Big Four have average temperatures colder than Anchorage, Alaska.

Yes.
Alaska.

The average temperature through the first 16 days of April in Anchorage was 37.3°. Iowa City has the warmest average temperature, as you would expect with it being the farthest south of the Big Four, at 35.0°. That is a full 2.0° colder. The capital city in Alaska, Juneau, has an average temperature through the 16th of 38.9° – nearly 4.0° warmer than Iowa City thus far in the month.

Warmer air is on the way. The Climate Prediction Center is calling for a chance of above normal temperatures to close out the month.

Record Cold High Temperatures

There’s no better way to say this — it just wasn’t a great weekend in eastern Iowa.  If it’s going to be this cold, might as well set some records, right?

Here are the high temperatures from April 15th across eastern Iowa:

These are high temperatures we typically would see in late January or early February.  They were good enough for the coldest high temperatures for the date.

Very Cold Start to April

If you thought it was a cold start to the month of April, you are absolutely right.

In fact, the average temperatures for April 1-10 for Waterloo, Dubuque, Cedar Rapids and Iowa City were the coldest on record in the Big 4.

Colder than normal temperatures are forecast through the next couple of weeks.  The average high this time of year is nearing 60°.

Record Cold Tuesday Morning

It was another very cold April morning across eastern Iowa, with temperatures generally in the 20s.

A few areas dipped into the teens, like Waterloo, which broke the old record of 18°.

Temperatures warm up over the next few days, before cooling down later this weekend and into next week.  Average highs are around 60° April 16th through 20th.
