Comparing this year’s time between spring and fall freezes
Much of the area had the first freeze of the season this past weekend, dropping to 32 degrees or colder. While you may have been thinking “this already?” it turns out our time between the last spring freeze and the first fall freeze was not any shorter than usual. Cedar Rapids’ last freeze this past spring fell on April 28, and the first freeze of fall was October 12. 166 days fell between freezes, and the average is 165 days. The biggest gap between spring freeze and fall freeze was 207 days from April 13 to November 7, 1900. The shortest period was 119 days from May 21 to September 18, 1929. Dubuque’s freeze gap this year is the same as Cedar Rapids at 166 days; the average is 163 days. The most was 208 days from April 12 to November 7, 1900.

What is wind chill?
The wind chill is simply how we, as humans, perceive the temperature to be or the feels-like temperature. It’s based on how much heat is lost from the exposed skin, caused by cold temperatures and windy conditions. For wind chill to go into effect, temperatures must be at or below 50 degrees and winds must be above 3 mph. Your skin naturally radiates heat, if a cold breeze brushes against your skin, the cold air will start to decrease the skin temperature. If you stay outside too long, that could start to lower your internal body temperature. This is what leads to frostbite. It’s always good to prepare when extremely cold temperatures are in the forecast. Remember to protect your pets and take precautions so your pipes don’t freeze. Fill up your gas tank, just in case you would need to stay in your car for an extended amount of time and always dress appropriately.
Nearly all Octobers have wind chills in the 20s
Cold air is not uncommon for October, especially these sharp cold blasts. They happen more often than you may think and in 95% of years, wind chills get as low as the middle 20s in October! In any given October, there’s about an 80% chance of our area having at least one hour of wind chills around 20 degrees. There’s only about a 30% chance of mid-10s wind chills. The coldest October wind chill on record in Cedar Rapids was set back in 1993 when it hit 6!
Beyond the Weather: Name a moon
Have you ever wanted to name a planetary object? Wouldn’t it be a great story to tell that you named a new moon? Now you have that chance. From now through December 6th, there is a contest to name the 20 recently discovered moons of Saturn. There are some rules as to what can be submitted for names, so you can’t just name one after your favorite meteorologist! All the information can be found at this link. Or, you can watch a video about the naming process here. Happy stargazing!
Difference between frost & freeze
Fall temperatures have finally arrived in Eastern Iowa. Normally we should have already seen our first frost across the area, but with a late warm up, it has been delayed a bit. What exactly is the difference between a frost and freeze? Frost forms on clear nights. Temperatures don’t necessarily need to be at the freezing point or 32°, but it can be upwards of 36°. Winds also need to be calm or less than 5 mph. A freeze is when temperatures are widely at or below 32 degrees. Winds also need to be light in this situation. When all these factors are present, including moisture near the ground, frost can form. Heading into the nighttime hours and when the temperature becomes cooler than the dew point, the water vapor around grassy areas turns into a solid. In the extended forecast, though, some may have a chance of seeing frost by next week.
