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.

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
3/29/1964
3/24/1940
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
3/29/1964
3/25/1894
3/24/1940
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…

50s in January

Normal highs for late January run in the mid to upper 20s. It is normal for temperatures to get a little warmer than normal at any time of the year. January high temperatures near and above 50°, however, are less likely. We have seen multiple “January thaws” so far this month but this past weekend was exceptionally warm.

Waterloo actually tied a record high temperature on Saturday, January 20th:

Out of the Big Four in our area, Waterloo was the only to hit 50° this past weekend. January temperatures have not been this warm in five years. In the past decade, only two other years have had highs reach or surpass 50°.

Click the photos below to enlarge. These charts show how many January days warmed to at least 50° through Sunday evening (January 21, 2018).

Waterloo:

Dubuque:

Cedar Rapids:

Iowa City:

It was almost five years to the date since Waterloo recorded a January high in the 50s. The high on January 19, 2013 was an even 50°…the same as the high on January 20, 2018. Cedar Rapids, Dubuque and Iowa City saw their last 50° January high near the end of the month in 2013.

Dubuque 01/29/13 high: 55°
Cedar Rapids 01/29/13 high: 58°
Iowa City 01/29/13 high: 59°

Sunshine broke through clouds in southeastern Iowa today. Temperatures there climbed into the 50s by midday.

Temperatures may near 50° later this week.
