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…

Snow in March?

Yes, even though March is known for the month of spring, snow does fall.  Typically, eastern Iowa sees anywhere from a few inches, to a half foot.  This March and last month have proven to be a little more on the snowy side.  Last year, a winter storm brought 2 to 10″ of snow to eastern Iowa on March 12th and 13th.  This year, of course, we had the 0 to 16″ snow event Friday night into Saturday.

That snow event set a record daily snowfall for Waterloo on March 24th, with 7.9″ of snow falling.  That beat the old record of 2.0″ set on that date in 1903.  Total snowfall for Waterloo was 8.5″, with 0.9″ falling before midnight Friday night.

Here are a look at the top 10 snowfalls for Waterloo, and some March snow stats:

As you can see, Waterloo only needs 1.1″ of snow to make it into the top 10 snowiest for March.  Will we do it? Possibly.

Here are a look at Dubuque’s stats.  Notice, we are several inches from the top 10 there.

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).



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.

Halfway There

We are officially halfway through meteorological winter. Typically, this marks the coldest three months of the calendar year – December, January and February.

We are also just about halfway through the month of January. The first half of January is commonly the coldest period of the year. Soon, normal highs begin to increase slowly. Average highs this time of year are in the mid to upper 20s.

January has defended its title of “coldest month of the year” pretty steadily up to this point. So far, there have only been a handful of days that warmed to or above average. In the four images below, the dotted pink line represents the normal high temperature for that date while the dotted blue line shows the normal low temperature. The red bars symbolize high temperatures and the dark blue bars illustrate the low temperatures.



Cedar Rapids:

Iowa City:

Warmer temperatures track in later this week.

As far as winter precipitation goes, here are the numbers for January 2018 and meteorological winter 2017-2018 (so far):

Waterloo January snow: 2.0″
Waterloo Dec 1 – Jan 15 snow: 9.7″
Average snow Dec 1 – Jan 15: 13.6″

Dubuque January snow: 3.4″
Dubuque Dec 1 – Jan 15 snow: 9.1″
Average snow Dec 1 – Jan 15: 16.6″

Cedar Rapids January snow: 2.6″
Cedar Rapids Dec 1 – Jan 15 snow: 10.3″
Average snow Dec 1 – Jan 15: 12.6″

Iowa City January snow: 1.2″
Iowa City Dec 1 – Jan 15 snow: 7.3″
Average snow Dec 1 – Jan 15: 12.7″

So far this season, our snow totals stand below normal for this point in the season. Dry and drought conditions are actually present in parts of eastern Iowa.

Wintry mix is possible this upcoming weekend.

December 2017 in Review

Now that we are a few days into the New Year, let’s look back at the last month of 2017:

Mild Days Ahead, Before Winter Returns

Enjoy the mild temperatures while they last, because change is on the way as we head into the winter season.  (FYI: Meteorological winter begins Dec. 1, while astronomical winter [solstice] begins Dec. 21 at 10:28 AM this year).

Temperatures will be in the upper 30s to mid 40s across eastern Iowa through Wednesday.  It’s late Wednesday into Thursday that we see a strong trough dig into the southwestern United States. An area of low pressure develops at the base of the trough, and will begin to track northeast.

At this point in time (Saturday evening), there’s still a spread in guidance as to where the low pressure will track, which will be crucial in forecast how much rain/snow/mixture we receive, and the amounts. The Weather Prediction Center has out probabilities of seeing a quarter of an inch of snow/sleet (melted).  The greatest chance for that is across northern Iowa (click the image to make larger).


It will also determine how warm temperatures will get before colder air moves in behind.  We are a bit more confident in the cold air behind the system.  How cold?  That’s where confidence is lowered again.  It will all depend on the track of the storm and how much (if any) snow is on the ground.  Stay tuned for further updates.

In fact, the Climate Prediction Center has much of the center of the nation with a good chance of having below average temperatures through the end of the year.
