It’ll be breezy Sunday afternoon.

Saturday rain chance

A cool front drops southward from Canada on Saturday, with cooler air arriving in southern Minnesota late in the day.

The front will help initiate some scattered showers and thunderstorms on Saturday. In the Twin Cities metro area, the best chance of scattered showers and a few thunderstorms will be Saturday afternoon into very early Saturday evening.

Some areas in Minnesota and western Wisconsin will see no rain this Saturday, but this will be our best chance of rain in the next three days.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential rain pattern from 4 a.m. Saturday to 11 p.m. Saturday:

NOAA’s High-Resolution Rapid Refresh model shows the following rainfall pattern for the same time period:

Pay more attention to the scattered nature of the rain in most areas rather than the exact location of the rain at any point in time.

Both forecast models show the best chance of significant rain will be in far southern Minnesota late Saturday afternoon into Saturday evening.
