Spring brings us beautiful blossoms and periods of rain. It’s unfortunate when rain interferes with outdoor plans.

The northern half of Minnesota is enjoying plenty of sunshine today, while clouds linger over much of southern Minnesota. Many locations from the southern third of Minnesota into west-central and southwestern Wisconsin have seen some Sunday morning showers.

A pesky low pressure system will slowly move away this afternoon, with showers ending by midday in central parts of the metro area, Showers could linger into mid afternoon in the far south metro and into early evening in portions of southeastern Minnesota.

The National Oceanic and Atmospheric Administration’s High-Resolution Rapid-Refresh model shows the potential rain pattern from 6 p.m. Sunday to 11 p.m. Sunday:
