Tornado safety tips
If you are in a home, small building, nursing home, hospital, factory, shopping center or high-rise building:
- Go to a pre-designated area such as a safe room, basement, storm cellar or the lowest building level. If there is no basement, go to the center of a small interior room on the lowest level (closet, interior hallway) away from corners, windows, doors and outside walls. Put as many walls as possible between you and the outside. Get under a sturdy table and use your arms to protect your head and neck.
- If you are in a pickup line at your child’s school, get inside the building as quickly as possible.
- In a high-rise building, go to a small interior room or hallway on the lowest floor possible.
- Make sure you are wearing sturdy shoes.
- Do not open windows.
If you are in a mobile home, manufactured office building or camper:
- Get out immediately and go to a pre-identified location such as the lowest floor of a sturdy nearby building or a storm shelter. Mobile homes, even if tied down, offer little protection from tornadoes.
If you are not in a sturdy building, there is no single research-based recommendation for what last-resort action to take because many factors can affect your decision.
Possible actions (which do not guarantee safety) include:
- Immediately get into a vehicle, buckle your seat belt and try to drive to the closest sturdy shelter. If your vehicle is hit by flying debris while you are driving, pull over and park.
- Take cover in a stationary vehicle. Put the seat belt on and cover your head with your arms and a blanket, coat or cushion if possible.
- Lie in an area noticeably lower than the level of the road and cover your head with your arms and a blanket, coat or cushion if possible.
How we describe hail size
Traditionally, common objects like peas and golf balls and softballs have been used to describe the hail you may see. Here's a guide to help.

Some schools let out early
With the storms expected to hit mid- to late afternoon in many areas, some schools released their students early. Others completed the school day but canceled evening activities.
Most early dismissals were limited to northern Iowa districts, including Algona, Belmond-Klemme and Eagle Grove.
You can see a full list here.
Significant severe weather possible
A "moderate" or Level 4 of 5 severe weather risk remains in place for northern Iowa — specifically areas north of Highway 20.
Hearst Owned
Significant severe weather is possible today across northern Iowa, with a few scattered storms for the rest of the state.
The rest of the state remains in a Level 3, or "enhanced" risk for severe storms.
This elevated risk is due to significant amounts of heat, moisture, and wind shear that will arrive Monday. Temperatures will top 80°, humidity levels will be the highest yet this spring, and winds will gust around 40 mph. Aloft, a ribbon of wind called a jet streak will further enhance the atmosphere's wind shear.
All this means the atmosphere will be primed to produce tornadoes, damaging winds and large hail — IF storms can ignite.
The most likely area to see more widespread severe weather will be across northern Iowa this afternoon into the early evening. More isolated storms are possible for central and southern Iowa, developing later in the evening. There may only be one or two storms in this zone, but if they form, they will likely be severe.
Hearst Owned
Very large hail, damaging winds, and a few tornadoes will be possible with any storms today.
Number of storms could be limited
While the ingredients are there for severe weather, it's not certain storms will actually be that widespread.
The main limitation will be a lack of obvious triggers in Iowa to help storms start. Low pressure will be centered well to our north in Minnesota. The most likely feature to watch will be a boundary called a dry line moving into Iowa from Nebraska later in the afternoon.
This dry line could set off storms that travel eastward through Iowa.
Long window of storm potential
Storms likely won't start up until early to mid-afternoon Monday.
Northern/northwest Iowa will be the first area to watch. The approaching dry line will approach areas like Pocahontas and Emmetsburg around 1-4 p.m. Storms could fire then and zoom east near and north of Hwy. 20 into the evening.
Farther south, the likelihood of storms is more questionable.
The previously mentioned boundary will eventually travel through the rest of Iowa. For the southern two-thirds of the state, 4 p.m. to 8 p.m. is the current window to watch for storm development. Any storm that develops in this zone will move east quickly with a significant risk for severe weather.
Some additional storms are possible between 8 p.m. and Midnight as the main cold front pushes through the state, but these storms are less likely to be severe. By midnight to 2 a.m., the threat should be move out of southeast Iowa, leaving us quiet the rest of the night.

Questions remain on just how widespread storms will be, but any storms will initially form in northwest Iowa, with risks increasing elsewhere by the evening.
