Seasonal Snowfall

Snow may be the last thing on your mind with the warmer weather during this last full week of April. Temperatures have topped out in the 60s and 70s since last weekend.

Winter may have had its final encore for this season in eastern Iowa.

Let us take a look back. This season we have seen:

  • 45.6″ in Waterloo
  • 38.2″ in Dubuque
  • 41.6″ in Cedar Rapids
  • 26.7″ in Iowa City

Waterloo, Cedar Rapids and Iowa City will all go down as above normal snowfall years (for the 2017-2018 season). Both Waterloo and Cedar Rapids had 10″ more snow than average. Dubuque will be the only member of the Big Four to end the season below normal.

More above (and some below) normal snowfall years occurred here in eastern Iowa over the past five seasons.

Waterloo:

  • 2016-2017: 26.2″
  • 2015-2016: 46.0″
  • 2014-2015: 29.2″
  • 2013-2014: 58.0″

Dubuque

  • 2016-2017: 27.2″
  • 2015-2016: 34.8″
  • 2014-2015: 33.7″
  • 2013-2014: 63.3″

Cedar Rapids

  • 2016-2017: 17.4″
  • 2015-2016: 15.1″
  • 2014-2015: 24.1″
  • 2013-2014: 42.9″

Iowa City

  • 2016-2017: 11.7″
  • 2015-2016: 12.2″
  • 2014-2015: 24.8″
  • 2013-2014: 36.1″

Thank you for all of your reports and photos during the snow season. Now we look forward to your rain reports as temperatures continue to climb moving toward summer.

Slow Start to Severe Weather Season

The colder than normal temperatures so far this spring have not only been affecting Iowa, but much of the lower 48.  Since January 1st (as of April 21st) there have been a preliminary count of 225 tornadoes in the United States.   That may seem like a lot, but according to NOAA, the 10 year average between 2005 and 2015, through April 21st, is around 371 tornadoes.

Here in Iowa, there have been 232 tornadoes in the month of April, from 1980 through 2017.  That’s about 6 tornadoes per year, on average.  Iowa has had no tornadoes this month, and none for 2018, so far.

That means we have something in common with Oklahoma.  They have also had NO tornadoes for the month of April, AND for the entire year.  There has never been a year, since 1950, where Oklahoma has had ZERO tornadoes from January to April.  This year may change that, as the chances for severe weather for the rest of the month are pretty low.  The latest first start to the tornado season was back in April 26, 1962 (according to the Tulsa National Weather Service).  The only two years without tornadoes in April, in the state of Oklahoma, was 1987 and 1988.  Click here to view the number of tornadoes, per month, since 1950 from NWS Norman.

Reports from April 18, 2018 Snow/Sleet/Rain/Freezing Rain/Thunder/Graupel/Rainbow Event

We had a little bit of everything yesterday as an April winter storm tracked through the KWWL viewing area. A few saw a rainbow in Bremer and Black Hawk Counties and we even had a severe thunderstorms within the snow/sleet that produced some hail. Freezing rain, rain, sleet, snow, graupel (a type of precip that looks like tiny pellets of styrofoam), hail all fell from the sky yesterday morning before transitioning to mainly snow. The mix cut down on snowfall amounts but areas in the north had mainly snow, so totals were much higher.

Snow Problems

Denver has a track meet on Thursday. Four inches of snow and some ice today has the track covered. This evening, athletes of the track team were working to clear the snow so when the sun comes up tomorrow and the warmer temperatures, the snow on the track melts enough to have the meet.

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 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.
