By The Numbers….A Cold Version

Since the winter has been so cold, I have been able to show you many stats to show just how cold it really has been. The first one is the chart below. It shows the number of days with the temperature zero or colder for each year. Yes, we have had a lot this winter. I want to draw your attention to and compare how many we have so far this winter compared to the previous three years COMBINED. That is correct. We have had more days with temperatures below zero this year than the past three years combined (Waterloo will exceed the 3 yr total by the weekend).

Feb 26 Zero or Colder

 

Now the next graphic is from Iowa Environmental Mesonet. It shows the percent of time spent below freezing (32 degrees) this winter.

Cold Weather Facts for Waterloo

Cold Thermometer
Our good friends at the NWS in Des Moines went digging through the record books to find the following information.

Here are the number of days of zero or colder in a winter year (Jul-Jun):

Record is 62 days (1977-78)

Average is 23 days

So far this year (2013-14) Waterloo is at 42 (including this morning)

Since the 1977-78 winter the only other one to match that was the next year, 1978-79, which had 42 total (we are sure to break that).

Winters with more than 42 days, other than 1977-78, are:

1976-77 (53)

1916-17 (48)

1917-18 (45)

1935-36 (44)

 

Here are the number of days of zero or colder in a winter season (Dec-Feb):

Record is 53 days in (1977-78)

Current year is at 40 (including this morning)

Other years at 40 or higher are

1976-77 (50)
