(IowaStormCenter.com) — A pacific storm system will bring severe thunderstorms and heavy rainfall starting later today, maximizing tonight through Sunday, and ending Monday.
Strong upper divergence with instability will promote a low-end severe weather threat starting around 4-5 PM from southwest through central and into northeast Iowa. This activity will continue south and east through the afternoon and evening with a hail and damaging wind threat.
Then additional convective development is anticipated tonight through Sunday where the threat will transition to primarily heavy rainfall across southern Iowa.
