About 53% of Minnesota (yellow) is abnormally dry, but not yet in drought. Only 8% of Minnesota is not either abnormally dry or in drought.

The Twin Cities metro area is currently in moderate drought, according to U.S. Drought Monitor. Minneapolis-St. Paul International Airport has tallied just one-tenth of an inch of rain this June. That is about three inches below normal for this point in the month, and May rainfall was more than two inches below normal.

Parts of the east metro area did receive between one and two inches of rain on Saturday, June 10, but those locations are still more than one inch below normal for this point in June.

Weekend rain chances

An approaching cold front plus the heating of the day will combine to generate some showers and thunderstorms Saturday and Saturday evening. Some thunderstorms could linger overnight Saturday night. A few patchy showers will be possible on Sunday.

NOAA’s North American Mesoscale forecast model shows the potential rain pattern from 4 a.m. Saturday to 7 p.m. Saturday:
