Our final weekend of August will feature some showers and thunderstorms at times, but many dry hours too.
The first batch of showers and thunderstorms is expected to spread across Minnesota and western Wisconsin Friday evening and overnight Friday night, then linger into early Saturday in northern Minnesota and parts of eastern Minnesota and western Wisconsin. Another batch of showers and thunderstorms will affect parts of Minnesota and western Wisconsin late Saturday afternoon into Saturday night.
The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential rain pattern from 4 a.m. Saturday to 7 a.m. Sunday:

It’ll rain in some areas that look dry in the model loop. We’ll have some updated model depictions of weekend rain potential tomorrow.
