Parts of central and northwest Iowa have been upgraded to a moderate risk (level 4 of 5) for severe weather tonight. This means widespread severe weather is likely with tornadoes, damaging wind gusts, and large hail all expected with storms that form.

A moderate risk for severe weather is in place for parts of central and western Iowa tonight. This is a level 4 out of 5.

After sunset

The initial line of storms will quickly move northeast, but another line of storms will form along a boundary in eastern Nebraska/far western Iowa after 8 PM. This secondary line of storms will produce damaging wind gusts, isolated tornadoes, and some large hail. The best potential for tornadoes will be west of I-35 and north of I-80 — in areas stretching from Algona, Fort Dodge, Jefferson, and Audubon and west.

Threats and timing

  • Tornadoes: Multiple tornadoes are possible today. A few are possible in NW Iowa between 5 and 9 PM, but many will also be possible between 9 and 11 PM. This will make them especially difficult to see.
  • Hail: Large hail over golf ball-size are possible, especially in NW Iowa between 5 and 7 PM. Some large hail at or larger than 1″ is possible with the second line after 9 PM.
  • Wind: Damaging wind gusts are likely, especially with the second line that will form in far western Iowa after 8 PM. It looks to approach the I-35 corridor between 11 PM and midnight.
