Iowa sees radical temperature extremes in January, from 24-below to 68-above

News, Weather

February 3rd, 2015 by Ric Hanson

Iowa’s weather during January featured several extremes. State climatologist Harry Hillaker says there were radical shifts in temperature, for starters, and despite the heavy snow that blanketed much of the state over the weekend, Iowa ended up lacking for precipitation during the month. “Very cold, generally speaking, for the first half of January, very mild and rather dry for the second half other than the big storm that came into the state on the very last day of January,” Hillaker says. “If we look at the state as a whole, the month ended up being about 2.3 degrees warmer than normal.”

In Atlantic, our average high for the month was 36. The average Low was 13. The normal High is 29, while the normal Low is 9. Most of Iowa got whalloped by a monster winter storm over the weekend that dumped up to 14-inches of snow on some areas of the state. Still, February 1st was Sunday, so the statewide average for precipitation during January was only about half-an-inch, which is about half the norm for the month.

“That basically does not include that event on the last day of the month,” Hillaker says. “For most of the official weather observers, their last report for the month would have come at 7 AM on January 31st, and all of that snow we had for the weekend came after that time, so it’ll end up in February’s records.”

In Atlantic, prior to the snow storm, we had received just 17 one-hundredths (.17”) of an inch of precipitation in January, from melted snowfall. Including snowfall for the 24-hour period that covered the 31st thru 7-a.m. Sunday, we received a total of .78” (78 one-hundredths of an inch) precipitation. Normal precipitation for the month is .84”

Hillaker says Iowa’s high and low temperatures for January were more than 90 degrees apart.
“Cherokee had the lowest temperature of the month, down to minus 24 degrees,” Hillaker says. “Then, toward the tail end of the month, right before the big snow event, we did have an impressive -for January- high of 67 degrees down in Shenandoah on the 28th day of the month.”

The lowest temp for the month in Atlantic, was -10 on the 12th and 13th of January. The warmest day was 59 degrees on the 16th. February started off much colder than normal and, for most of the state, much snowier than usual, too. Temperatures will likely stay below freezing this week and he says there will only be a little melting of the mounds of snow.

Snowblowers are droning and shovels are scraping concrete as most Iowans are digging out from a weekend that brought heavy snow to much of the state. Winter Storm Warnings were issued from Saturday afternoon into Sunday night as the steady rain changed to heavy snow. Meteorologist Brad Small, at the National Weather Service in Johnston, says virtually all of Iowa got at least some snow and many cities got more than a foot.

“Really, the worst-hit areas were from southwest Iowa through the northern Des Moines metro area,” Small says. “We had, here at the office, 14.2 inches and amounts from 8-to-13 inches were pretty common…through the Cedar Rapids area to just north of the Quad Cities. There’s about a third of the state saw better than ten inches.”

Many churches across the state cancelled worship services on Sunday and some flights were cancelled at Des Moines International Airport, while today (Monday), schools in Cedar Rapids, Iowa City, Dubuque and other districts have canceled classes and Mason City and Ames, among others, started late. Meteorologist Jim Lee, at the National Weather Service, says the most remarkable aspect of the storm was the precipitation amounts. Lee says, “When you took the total of the rain and melted snow, some areas got more precipitation in 24 hours than they normally see in the entire month of January.”

A week ago, a warm-up washed over Iowa and brought high temperatures in the 50s and 60s to many areas. That’s long gone, though, and Lee says this snow will be sticking around for a while. “The first chance to even get above freezing in most areas is around Friday and that won’t be by much,” Lee says. “So, we may see just a little bit of melting and certainly some compaction but no significant warmups or melting on the horizon.”

Highways in southwestern, central and eastern Iowa are still covered with snow according to Iowa Department of Transportation road conditions website. A 48-mile stretch of Highway 6 in southwest Iowa, between Council Bluffs and Griswold, was declared “impassible” due to drifting and blowing snow bringing white-out conditions.

Windy conditions with continued snowfall are expected through the evening hours causing hazardous driving conditions. The Iowa Department of Transportation is working to clear roads, but blowing snow can cause roadways to quickly become re-covered after trucks pass through. Visibility can also be greatly reduced due to blowing snow.

Iowa DOT reminds travelers that trips during severe winter weather can take three or four times longer than normal. Motorists are urged to monitor weather and road conditions before traveling and evaluate the necessity of trips. Often, the safest option is to skip the trip altogether. For road condition information visit the Iowa 511 website at http://511ia.org or call 511 within Iowa, or 800-288-1047 from outside the state. Tow ban information can be found on the full-featured version of the website.
