A Look Back and Ahead

June wound up being a wet month for many locations in Iowa. The map below shows the radar estimated rain totals for the month of June.


Here are a few monthly rain totals in eastern Iowa.
Waterloo 5.47″ (+0.49″ of normal)
Dubuque 8.34″ (+3.49″ of normal…10th wettest June)
Cedar Rapids 8.85″(+3.93″ of normal)
Iowa City 5.88″ (+1.27″ of normal)

Other rain totals across the state:
Des Moines 8.40″
Mason City 5.04″
Ottumwa 7.79″
Sioux City 4.19″
Burlington 7.06″

At times it felt like it rained every day of the month. In reality it didn’t here are the number of days with 0.01″ of rain reported.
Waterloo 10 days
Dubuque 12 days
Cedar Rapids 13 days
Iowa City  14 days

A look at the average temperatures shows near normal readings in June
Waterloo -0.7° of normal
Dubuque -04.° of normal
Cedar Rapids -0.4° of normal
Iowa City +0.3° of normal

The look ahead shows more wet weather with potentially above normal rain and below normal temperatures across Iowa.

May 2015 was wettest month ever recorded in U.S.

Last month, much of the United States was wet. How wet? When climate scientists at NOAA’s National Centers for Environmental Information averaged the observations of rain, snow, and other precipitation from across the country, they found out it the country’s wettest May since records began 121 years ago. In fact, it was the wettest month ever recorded!

May 2015

Well, the month of May is over. June 1st is the start of the Atlantic hurricane season and the “meteorological start” (June/July/August) to summer. Let’s take a look back at some numbers for May. First I will start with the rain. I touched on this a little bit in my post yesterday.

Month Rainfall

When it comes to rain amounts, the numbers can vary greatly from location to location. It is just the way it is. The same amount of rain doesn’t fall across a town, or county or half of the state. So your numbers are most likely not going to be exact. You would be surprised at how many people question the number because they have a tenth or two more or less. Anyway, back to the official climate reporting locations. Three of the four, on the graphic above are close to 0.50″ either above or below normal. The exception would be Dubuque. The map be  low may be a little hard to see the labels, but the one thing to take from the graphic is there isn’t one location in Iowa that had very little or a whole lot more rain than the rest of the state.


Despite the rain and the amount of hours of measurable rain, the average temperatures were all a little bit above normal.
Average Month Temp

Hold on one second…………………………………………………………………………….

………………………………………….Ok I am back. I just went back to count the number of days we saw 80 degrees or warmer this may compared to May 2014.

Town: 2015/2014
Waterloo: 6/7
Dubuque: 3/8
Cedar Rapids: 5/9
Iowa City: 7/11

Each location had a few more days at 80 degrees or warmer last year than this year (in May).

Normal Date of Last Freeze


The normal last freeze date is about this time of  year. Don’t be surprised to see frost or a freeze later this week (Thursday and/or Friday morning).

90° Facts

It’s been a cool summer with only a handful of locations hitting 90° or warmer. Take a look at these 90° weather facts:

Record Breaking Warmth in 2012


You would probably agree that 2012 was a warm year, but did you know it is the warmest year on record. It beat the old record by one degree.

Here are the top 5:

2012: 55.32 deg
1998: 54.32 deg
2006: 54.30 deg
1934: 54.13 deg
1999: 53.93 deg

From NCDC:

According to NOAA scientists, the average temperature for the contiguous U.S. for 2012 was 55.3°F, which was 3.2°F above the 20th century average and 1.0°F above the previous record from 1998. The year consisted of the fourth warmest winter, a record warm spring, the second warmest summer, and a warmer-than-average autumn. Although the last four months of 2012 did not bring the same unusual warmth as the first 8 months of the year, the September through December temperatures were warm enough for 2012 to remain the record warmest year, by a wide margin.
