Preview of Thursday’s flood outlook factors

With the active, very snowy pattern the past five weeks, the question of “what is spring flooding looking like?” has come up more and more. The National Weather Service is set to release its first spring flood outlook of the season on Thursday, February 21. An updated outlook is scheduled for Thursday, March 7. There may be additional outlooks depending on conditions. While the amount of snow is often top-of-mind when it comes to spring flood potential, it’s just one of several things that forecasters look at. In addition to the location of the snowpack and how much water is within it, they also consider: - Fall precipitation and soil moisture going into winter - How deep frost is in the ground - Melting conditions - Upcoming precipitation trends (odds of it being wetter or drier than normal) - Streamflow (the amount of water already going through rivers) - River ice Soil moisture is running very high because of the wet weather in the fall that lasted into December. That means the soil can’t hold a lot more water. Currently, frost is about one to two feet deep. Streamflow is generally near or a bit above normal; since they’re not running too high, they can deal with some rises. Finally, there is about an inch or two of water in the snowpack right now, with two to four inches in northern Iowa and southern Minnesota where some of our rivers begin. Thursday’s outlook will detail what the odds of spring flooding are compared to historical averages on rivers throughout the area.

Snow moves in late Saturday night, continues Sunday

More snow is on the way this weekend. TIMING: We expect snow to start late Saturday night, primarily after 10pm. This snow will last the entire day Sunday and wrap up sometime Sunday evening for the most part. Lingering flurries may still fly into Monday morning. AMOUNTS: A widespread 3-5" of snow is expected by the time the system is through our area. It will take the entire day Sunday to get to this range as it'll be a prolonged lighter snowfall. IMPACTS: Roads will quickly become snow-covered and slick. Blowing and drifting snow doesn't appear as much of a concern due to wind staying at or below 15mph in many areas. The snow will be a powdery consistency, leading to easier snow removal than the last event which was heavier with sleet and freezing rain also weighing it down. Temperatures will remain in the 20s for the duration of the event.

Beyond the Weather: Goodbye, old friend

Many times, we look beyond the weather at objects in the heavens above. When the weather cooperates, we end up with many spectacular views in Iowa. Mars is often on our list of targets. The red planet can been seen this weekend in the west-southwest evening sky. While you can easily find Mars, you cannot see any of the exploration that has been done on the Martian surface. Back in 2004, NASA send a rover named Opportunity to the surface of Mars. As of Thursday, NASA has declared Opportunity’s mission on Mars at an end. More than 800 recovery commands have been sent to reestablish communication, but they have not succeeded. Over its more than 14 years on Mars, Opportunity has captured over 200,000 images, exploring more than 28 miles of the Martian surface. This page has more information. Happy stargazing!

Comparing this season’s snow to the 10 snowiest on record

The past month has had much more snow than usual, but we still have a lot of ground to make up to put this into one of the top 10 snowiest seasons on record. Through February 13, though, this season does crack the top 10 in most places and is just shy of the mark in Cedar Rapids. Remember that there wasn't much snow in December and the first half of January, which makes the ranking all the more interesting. Below are the snowfall totals for the season so far, along with the highest ten snowfall totals up through February 13, and the ten snowiest winters as a whole.
