OMAHA, Neb. (WOWT) - As we inch toward spring while in the midst of a record-cold snap, some may have flashbacks to this season in 2019. We’re once again experiencing frigid temperatures with several inches of snow on the ground. Will these conditions cause flooding concerns in the near future?
HEARTLAND FLOOD – 2019
A “perfect storm” of weather conditions led to catastrophic flooding beginning mid-March of 2019. Omaha Eppley Airfield picked up 27 inches of snowfall throughout February – a new record for the month! For the entire 2018-19 season, Omaha recorded 52.7 inches of snowfall, marking the 7th snowiest season on record.
In addition to the high amounts of snowfall, temperatures were frigid, with Omaha experiencing the coldest February in 30 years.
During the second full week of March, a storm system brought 1 to 3 inches of rainfall to the Heartland. This rain fell on top of ground that was covered with 16 inches of snow, and had a frost depth of 1 to 2 feet!
Temperatures quickly warmed into the 50s and 60s, rapidly melting the snow. Since the ground was frozen, the inches of rain and inches of snowmelt couldn’t seep into the ground. Instead, the high amounts of water caused rapid river rises.
SPRING FLOOD OUTLOOK – 2021
This past week, we have shattered daily records and have experienced some of the coldest temperatures in decades. As of February 17th, Omaha Eppley Airfield has picked up 9.7 inches of snow during the month of February and 40.2 inches for the season-to-date. The current snow depth is 7 inches.
Compared to 2019, our frost depth is much shallower -- at just 4 to 9 inches across Nebraska and western Iowa. In this year’s case, our snow cover has acted like a blanket in keeping the ground warmer!
2020 was the third DRIEST year on record for Omaha, with much of the Missouri River basin still facing moderate to severe drought conditions into 2021. It should be noted the level of the Missouri River is VERY LOW. In Omaha, the Missouri River is at 10.2 feet, with flood stage beginning at 27 feet.
Though we do have pockets of heavy snow cover in Nebraska, the overall snowpack across the Plains and mountains is below-normal. Much of the Dakotas have little to no snow cover as of Feb 18th. Soil moisture is also below-normal.
With all of these conditions in mind, the National Weather Service characterizes our flood risk for the spring as “normal”. High temperatures next week will warm into the 40s, with generally dry conditions on tap, aiding in a gradual melt and thaw.
ICE JAM RISK
Though the overall flood risk is NOT elevated, there is an above-normal risk for ice jam flooding – especially along the Platte River, downstream of Columbus. The recent drastic cold snap has contributed to an increase in ice thickness in many areas. Once we begin to warm and melt, those who live along the Platte should remain alert for rapid rises.
Since we’ve already seen ice jam flooding around Fremont this winter, more issues in the future weeks and months are likely.
As always, this is a fluid and evolving forecast! The next flood outlook from the National Weather Service is scheduled for February 25th. We’ll continue to bring you developments as necessary. In the meantime, you can read the entire current outlook from the NWS here.

River level omaha
Current Missouri River level at Omaha
Last year, we were dealing with historic flooding on the Missouri River and several other local rivers. So far this year, we’re dealing with many other issues, but thankfully additional flooding isn’t one of them. In fact, the Missouri River is running at fairly “normal” levels in Omaha right now, but let’s do a quick recap of some historic highs and lows.
Right now, the Missouri River level in Omaha is near 18 feet. This is close to its average seasonal level. In fact, it’s less than five percent below the seasonal level.
After last year, a river level of nearly 18 feet might seem low. Which is understandable when just last year we added two historic crest levels to the “Top 5” here in Omaha. The first historic crest in 2019 happened on March 17th and the second on June 5th.
For reference, the highest crest was 40.40 feet on April 18th, 1952 and the lowest river level was 6.85 feet on February 5th, 1989. In Omaha, the Missouri River reaches flood stage at 27 feet and enters low stage at 10 feet. So, in the grand scheme of everything, a level of 18 feet is fairly average.

Although it would probably be more correct to say - after happiness, she did not refuse the offer. The first time of her life in our family was marked for me with terrible experiences. I was afraid that she would fail the exams and leave, but she passed everything, went to college, and I calmly exhaled.
I studied well, and managed to do all the lessons before Larissa came from the institute, and when she came, I became her tail, a faithful, faithful dog.
