Severe storms are now developing in extreme Western Iowa. Central Iowa has the highest potential of seeing strong tornadoes late this evening into the overnight hours.
STORM SET UP:
A strong area of low pressure with a warm front has lifted north across Iowa. South of the warm front, a very warm moist airmass will set up for the remainder of the night. A strong cold front is waiting in the wings in Nebraska. This will push into the warm moist airmass over Iowa.
These will be long lasting storms that could have rotation, leading to the development of strong tornadoes that could be destructive and stay on the ground for long distances.
These storms will then push east towards the I-35 corridor late this evening. These are the storms that may produce tornadoes. The area of coverage will expand through the evening and continue overnight.
WHAT TO EXPECT:
The severe weather threats include all modes: hail, damaging winds, tornadoes and even flash flooding (due to heavy rainfall in the storms). The morning threats are primarily hail and winds.
HOW TO PREPARE:
- Have an NOAA Weather Radio and make sure it is on. Make sure the batteries are working.
- Download the 13WarnMe App on your smart phone. This will notify you when the WHO-HD Weather Team is on the air with severe weather coverage. You can then watch on the app, as well as on Iowa’s Weather Channel (Channel 13.2). iPhone users click here – Android users click here

- Follow @WHOweather on Twitter
- Prepare now! Know where you will take cover if severe weather approaches. The best location is to get underground in a basement or storm shelter. The next best place is an interior bathroom or closet on the first floor of your home or building. Added protection includes wearing helmets (including bicycle helmets or sports helmets). Many deaths in tornado outbreaks are due to head injuries. You can also cover yourself with a mattress or cushions from a couch. Get your shelter set and ready to go this morning. Put your helmets, flashlights, non-perishable foods, and pairs of shoes where you will be taking shelter. Have your cell phones charged and ready to go.
