Saturday rain chance?

The National Oceanic and Atmospheric Administration’s High-Resolution Rapid Refresh (HRRR) forecast model shows the potential rain pattern from 7 a.m. Saturday to 2 a.m. on Sunday:

Notice that the HRRR model includes much of Minnesota in the scattered showers and thunderstorms at some point, bringing a bit of rain into portions of northeastern and east-central Minnesota late Saturday afternoon and Saturday evening.
NOAA’s North American Mesoscale (NAM) model keeps eastern Minnesota dry Saturday and Saturday evening, with scattered showers and thunderstorms in parts of western Minnesota, mainly during the afternoon and evening hours:

Any showers or thunderstorms that do develop shouldn’t last very long at any one spot. Sunday is looking rain-free at this point.
