(Radio Iowa) – It’s pretty rare Iowans get to run around in sweatshirts or light jackets in December, but unseasonably warm weather settled on the state late this week. Meteorologist Rod Donavon, at the National Weather Service, says Lamoni had the state’s hot spot with a record high temperature of 62-degrees on Thursday, one of many. “We did have several record highs, including Waterloo at 57, Mason City at 55, Ottumwa at 61,” Donavon says. “In addition, we had basically this entire area was in the upper 50s to low 60s, so a very mild day and well above normal.”
Today’s (Friday) forecast calls for cooler weather than yesterday, but still very comfortable for this time of year. “We are having a few more clouds passing across the state today,” Donavon says, “so it’s still going to be pretty mild high temperatures in the 50s, which is still within that 10- to 15-degree above-normal range.”
Much colder weather will move in tonight and overnight, bringing the chance of scattered rain or light snow across various parts of the state on Saturday. Highs for the weekend will be back around normal, in the 30s and 40s.

(Radio Iowa) – To some Iowans, it just isn’t the holiday season if there isn’t snow on the ground. If a white Christmas is on your wish list, you’ll have the best shot of finding flakes across Iowa’s northern-most counties. National Weather Service meteorologist Brad Small says they’ve studied the data spanning back decades and have compiled a map showing the probabilities of having snow on the ground on December 25th.
“Iowa can probably be generally weighted into four different tiers actually, with about a 60-plus-percent chance toward the Minnesota border, and then it steps down, Highway 20 corridor 50-percent, then 40, and then it gets down into the 30s as you get closer to the Missouri border,” Small says. “So it kind of behaves as you’d expect, with better chances the farther north you go.”

Since Christmas is still 19 days away, Small says it’s difficult to predict whether we’ll have a significant snowfall in Iowa by then. “It’s a little too far out to put too much on the end of the month,” Small says. “Probably the historical probabilities work better than anything else, at this point. There are some snow chances this weekend. Confidence in where that occurs and how much is pretty low, and it doesn’t look like to be a major system, so it’s potential, even if we do get snow this weekend, it could melt before Christmas.”
(Radio Iowa) – The weather is going to cooperate if you still have some outdoor work to do this week. National Weather Service meteorologist, Alexis Jimenez (hih-MEN-ezz), says temperatures are forecast to be double the norm. “Where our normal high temperatures are usually in the upper 30s around this time of year, we’re going to have temperatures reaching near 60 degrees, especially by Thursday. We can start seeing some records breaking,” she says.
The warmth will spread from the western side of the state. “The warmest will especially be in western Iowa on Wednesday, and Thursday it’s going to be much of Iowa will be near 60,” Jimenez says. If you are working outside, be prepared for windy conditions. “It’ll be a little bit breezy. The afternoon hours we’re expecting some gusts up to 30 miles per hour at times as we get through the middle part of the week,” she says. “So just be careful with that portion of the weather, but as far as temperatures go it’s gonna be pretty nice out there.”
As is always the case with warm weather in December, enjoy it while you can. “Those warm temperatures will last up until we get a cold front moving through on Saturday, where our highs will fall back down into the upper 30s,” according to Jimenez.
She says there is a chance for some rain in southeast Iowa on Saturday, and maybe some snow chances on the backside of it there as well.

(Radio Iowa) – State Climatologist Justin Glisan says the initial, long-term forecast for December indicates warmer temperatures and more precipitation, but there’s nothing to suggest there’s an amped up threat of a tornado outbreak like the one two years ago. “December 15th, 2021, that was an extreme event,” Glisan says. “We had a serial derecho and 63 tornadoes — the largest tornado outbreak for Iowa for any month and the largest December outbreak for the United States in the observational record.”
The latest Drought Monitor nearly all of Iowa has some level of drought, with some areas in extreme drought. Glisan says there is the potential for more precipitation to fall in December, but the old adage that it’s too dry to rain is true in SOME cases when thunderstorms hit dry pockets of air. “We saw this in western Iowa as the drought started in May and June of 2020. You would have thunderstorms approach the state and then just either break up or go around because there was no low level moisture to work with,” Glisan says. “Now in these larger scale low pressure systems they’re able to have more access to large scale moisture pools and hence you do see wider spread snowfalls or rainfalls.”
The seasonal outlook indicates abnormally wetter conditions along the southern coast of the U-S and that may provide the moisture weather systems sweeping across Iowa draw from and generate rain or snow.
