What's ahead for Monday's severe weather
DES MOINES, Iowa — We are watching the skies closely as many dynamics are coming together for severe weather in parts of the state by Monday evening. The ingredients we have include warm temperatures, high dewpoints (moisture), and wind shear of great speed and directional change with height. The one last thing we need is a lifting mechanism moving into the primed atmosphere to lead to storm development. It all comes down to an approaching cold front, and whether it moves in time to meet with these ingredients late afternoon and evening to cause storms to form. Models vary in the placement of the storm development this evening. A few supercell storms are expected to develop along the front and move into Central and Northern Iowa. Anytime after 5:00 p.m. and especially 7:00 p.m. on, you'll want to be near a location where you can take cover, if needed, and have a radar app, like 13WarnMe to be able to watch for storms coming your way. Here is a look at the morning run of the GRAF model: Here is a look at the HRRR model: CAPE (which is storm energy) and shear (which is twist of the winds with height by either direction or speed) will both maximize during the afternoon hours. As the cold front hits these two elements, we could get lift to allow storms to form sporadic in nature along the front in western Iowa and move into Central Iowa. The tornado threat appears to be highest in north central Iowa this evening. Although a tornado could fire up in any storm that forms along the front. The weather team will be live through the evening on WHO 13, WHO13+, and Iowa's Weather Channel for tornado warnings tonight. Copyright 2025 Nexstar Media, Inc. All rights reserved.

High winds, bursts of snow and low visibility expected early this week
(COLORADO SPRINGS) — The FOX21 Storm Team is monitoring a spring storm that could bring high winds and high snow totals for some for the early work week of March 3 including Monday night into Tuesday. Here's what you need to know to prepare. What We Know: A potent spring-like storm will arrive in the area starting Monday night and continue in the area through Tuesday. This system is expected to gain energy as it moves into Colorado and brings high winds and snow to the high terrain and lower elevations. In addition, this system is expected to tap into some moisture which means the snow will be pretty wet and slushy in some spots and the moisture could also act as a snow total multiplier and bring heavier snow potentially to Teller County and areas near Palmer Divide like Monument, Black Forest, Palmer Lake, Gleneagle, Calhan and into the gap between Monument and Castle Rock. It also means that some will get just rain while others will see snow. The image below shows Sunday's estimates where some will see rain (in green) and some will see snow (in white, grey, and pink colors). As this storm arrives in the area on Monday, it will first bring high winds and high fire danger to some dry areas including areas near Highway 50, and into the Raton Mesa and Baca County where humidity levels are expected to be below 15%. A Red Flag Warning is in effect for parts of the SE plains Monday from 11 a.m. to 7 p.m. Southern Coloradoans are warned to be cautious with any ignition sources Monday. As the wind continues to blow into the evening hours on Monday, we will start to first see rain and then eventually snow. It is expected that the snow will start to get heavier overnight Monday into Tuesday and bring high snowfall totals to Northern El Paso County and Parts of the Eastern Plains. A Winter Storm Watch is in Effect for Monday night into Tuesday. Potential Impacts To Your Monday Night Into Tuesday With this storm, you are going to want to watch out for 3 things: High Winds up to 50 mph Bursts of Heavy Snow especially for the Pikes Peak Region Terrible Visibility Heavy Snow For Some As mentioned above, the moisture content in this storm as well as the system's interaction with our terrain are going to determine how much snow falls and where. Below is a comparison between two models: The European model and the GRAF model which the Storm Team consults in their forecasting frequently. As of Sunday morning, the European model and the American models were shown to have a similar forecast (which is on the left of the image below) of going quite low on storm totals. However, the GRAF (which is shown on the right) and other models showed more moisture content and more terrain interaction which is pretty typical for spring-like scenarios here in Southern Colorado. You can view the model comparison below. Here are the preliminary snow totals for Tuesday for Southern Colorado and the Pikes Peak Region where the greatest terrain interaction is expected. High winds and diminished visibility This storm will also bring high winds. Winds are expected to gust up to 50 mph late Monday night through Tuesday afternoon. The winds will create the following issues: Blowing Snow and Blizzard Conditions which will knock down visibility. In some places, you will not be able to see the road in some spots. Danger to high-profile vehicles on west-to-east oriented roads. Slick conditions Wind chills will make it feel like single digits on Tuesday morning and teens in the afternoon. Road Conditions As you can see it is advised to stay home or at least limit travel as much as possible due to deteriorating travel conditions. Make sure to tune into FOX21's Storm Team Chief Meteorologist Matt Meister and Meteorologist Megan Montero will be live covering road conditions for Tuesday. You can also follow the Storm Team for the latest updates while not on air on the FOX21 Weather App. Copyright 2025 Nexstar Media, Inc. All rights reserved.

Iowa to see 3 more rounds of snow this week into next
As you've noticed, very cold air poured over the state Wednesday night behind our snowfall and under clear skies. Temperatures will moderate a bit into Friday. Your weather timeline takes you into Friday and through the first two snow chances in our forecast: It will be cold Friday morning, but not as cold as Thursday morning was. Still, we'll see wind chills below zero to start the day. Bundle up! And get ready for what could be a tricky pick-up time Friday afternoon. Snow looks to fall during the afternoon hours and into the very early evening on Friday, and will be accompanied by winds out of the SSE gusting to 30 mph. This will make for a challenging afternoon commute and could slow your drive to Valentine's dinner. The image below shows our GRAF computer model's snowfall forecast. The image following shows computer model snow total forecasts for the Des Moines area by Friday evening. Whether we get a half inch or two inches, driving will get dicey. The first image in the gallery below shows the wall of snow approaching the I-35 corridor at 3 PM Friday. That snowfall should be done by evening. Then a trickier snow forecast comes our way Saturday. Snow could fall from the early morning into the early evening, but what makes Saturday's forecast a tough one is that we could see one or maybe even two thin bands of heavier snow accumulation set up. These could be as little as a county wide and will create big snowfall total gradients over a small area. An example of one of those gradients is below, from the HRRR model. This shows Boone, for example, getting 6.6″ and Ankeny getting 2.1″. We'll continue to keep you updated as Saturday's forecast will likely change. Our third round of snow comes Monday during the afternoon hours. At this point totals look to be less than an inch by evening. Turning to temperatures, it's important to know that it gets very cold again starting Sunday. The extended forecasts following appear to keep us in below-average temperatures. As always, your WHO-13 7-day forecast can be found here. Be safe and stay warm! Copyright 2025 Nexstar Media, Inc. All rights reserved.
