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.


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 April Cold

It’s cold.  It’s plain and simple.  You and I both know its cold, and the record books show it.

Here are the high temperatures from Monday.  These are typically temperatures we’d see in February.

These are the coldest temperatures we’ve ever seen on April 16th.  Waterloo and Cedar rapids tied the record, while Dubuque and Iowa City broke the record cold maximum temperatures.

The first half of the month has been on for the record books.  Waterloo, Dubuque and Iowa City’s average temperature is the coldest its ever been for the first 15 days of April on record, with Cedar Rapids coming in as the second coldest.

Waterloo: 30.6°

Dubuque: 31.1°

Cedar Rapids: 36.4° (#2)  — (#1: 35.9° in 1975 )

Iowa City: 35.2°

There is good news, warmer temperatures are forecast by the end of the week, into the weekend.

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.

Record Lows & the Continuing Cold

Record lows could be reached across the area for April 1. It will all depend on if skies stay clear and winds stay low. 

Besides the daily low records, it could also be one of the coldest Easters across eastern Iowa. Below indicates the coldest lows for Easter in Waterloo since records began.

Date Low
4/2/1899 15°
4/11/2004 16°
3/30/1975 17°
3/29/1970 19°
4/11/1982 19°


If Waterloo hits, a low of 14° tomorrow it will be the 3rd coldest on record. Below are the record cold highs for Waterloo on Easter.

Date High
3/24/1940 21°
3/29/1964 21°
4/4/1920 30°
3/30/1975 31°
4/8/1928 33°
4/9/1950 33°
4/2/1899 34°
3/25/1951 34°
3/29/1970 34°
3/23/2008 35°


Tomorrow could be in the top 10 for coldest Easters on record in Waterloo. It’s also worth pointing out that if the airport only records a temperature of 34° or less, it will be the coldest Easter in the last 42 years!

Dubuque may be breaking Easter records tomorrow as well. Below are the record lows for Dubuque.

Date Low
3/30/1975 10°
3/25/1951 14°
3/29/1970 15°


If Dubuque hits a low of 14°, it could be tied for the 5th coldest low on Easter. Dubuque has a forecast high of 36° tomorrow which could put it into the top 10 for coldest Easters.

Date High
3/25/1894 18°
3/24/1940 23°
3/29/1964 24°
3/30/1975 25°
4/8/1928 32°
4/4/1920 33°
4/13/1952 34°
4/9/1950 35°
4/2/1899 36°
3/29/1970 37°

Similar to Waterloo, if Dubuque stays at 36° or less, this will be the coldest Easter in over 40 years!

Even if records aren’t broken, it will be a cold Easter for everyone across the state of Iowa.

And since I’m only providing great news (sarcasm), the Climate Prediction Center released it’s April outlooks today. We know the next 7 days will be cold and it looks like that stretch will continue into the following week.

Precipitation is expected to be near normal from April 8-14.

And it probably comes as no surprise, the Climate Prediction Center has confidence in Iowa staying below normal for April. Precipitation may be a bit above normal for the month. I’m sure most of us hope that it is in the form of rain…

Taste of Spring

Now that we have moved our clocks ahead one hour for Daylight Saving Time, many of you probably have spring on your mind.

The next couple days will be on the cool side, before we rebound to seasonal averages by Wednesday.

As we head into the end of the work week, through next weekend and into the early part of the following week, eastern Iowa has a good chance to see at or slightly above normal temperatures.  The normal high this time of year is in the lower to middle 40s.

Beyond that, as we round out the month of March and head into spring, temperatures appear to be on the cooler side.  However, there’s still plenty of time to iron out the details.

Snow vs No Snow

It’s been a snowy first half of February across not only eastern Iowa, but the entire state.  The melting process has begun, with temperatures in the 30s and 40s.

There’s also several inches of snow across the state, which is keeping these temperatures cooler than what they would be if we had no snow on the ground.  Radiation from the sun bounces off the snow and take that energy back up to the atmosphere (known as ‘albedo’), which limits warming over snow-pack.

Notice in northern Missouri, temperatures are in the 50s, to near 60°, with little to no snow on the ground.  Also, there’s even clouds in southern Iowa and northern Missouri, limiting the heating in that region.

Here is a satellite picture that was taken during full sunshine on Tuesday, February 13.  You can the entire state of Iowa covered in snow.  The rivers show up nicely.

When we look at the satellite view Friday, A lot of the snow across the state of Iowa will be melted.

Cold and snow on the way

Ready or not, the frigid cold is on the way later tonight as a cold front pushes south across the state. Along the cold front a few snow shower or flurries are possible, north of Highway 20. The radar image shows the light snow shower across southern Minnesota. They are moving southeast. A dusting of snow is possible in a few locations. Many areas stay dry.

Here is a look at the frigid cold just to our north this evening. Lows tonight are in the single digits and teens.

The weather pattern is changing to become a more active one. It will also keep cold air in place to any chance of precipitation in the next week or two is should be all snow. Light snow chances are Saturday, Monday and Wednesday. We might get more snow in the first half of February than we have all winter so far. Time will tell.
