Northwest Iowa — Thunderstorms moving through this morning are not expected to be severe, but additional storms later today and tonight will have the possibility of producing large hail and damaging winds.
There is a small chance for storms very late afternoon into early evening west of the James River, which would be capable of hail up to ping-pong ball size with winds to 75 mph. Other storms will pop very late evening through the overnight to the east of the James River, and could produce hail to half dollar size and winds to 60 mph. Be sure to have multiple ways to receive warning information should storms become severe later today.
Several waves of showers and thunderstorms will move through the region through Saturday, giving a good chance for rainfall across the area. While heaviest rainfall will be spotty, many areas should see a half inch to inch of badly needed rainfall. Severe storms will also be possible, with a few late day storms capable of hail/damaging wind west of the James River, and a few storms later tonight/early Friday potentially severe as far east as southwest MN and northwest IA. The main severe threat by later Friday should be brief, and mainly through the Missouri River corridor and south. Scattered storms will continue Saturday, but drier and seasonable conditions should settle in on Sunday.
