Isolated showers and thunderstorms moved through Minnesota Sunday morning, as muggy weather returned to much of the state.

A line of severe storms moved southeast through the northern part of the state early Sunday. Golf ball-sized hail and wind gusts up to 67 mph were reported, the National Weather Service says.

Expect another day of warm temperatures and higher humidity Sunday, the weather service notes. Temperatures will range from the upper 70s in northern Minnesota to near 90 degrees by the Iowa border, with humidity levels on the "high side" in the central and southern parts of the state.

Thunderstorms could redevelop Sunday afternoon in far eastern Minnesota, weather officials say.

A cold front that's in the Dakotas Sunday will push through Minnesota in the evening, bringing cooler and drier air pressure for the first half of the week, the National Weather Service says, with weather officials saying people will start feeling the change in weather Sunday night as lows drop about 10 degrees.

Temperatures this week are expected to be slightly below average, the weather service says. The chance of rain returns to the area in the second half of the week.
