Undated (AP) _ Fair skies prevailed over much of the nation today, but summer-like weather got thunderstorms rolling in the Great Plains and the Mississippi Valley.

Warm and humid weather in the central United States on Monday produced temperatures in the 80s and 90s and hail in parts of Texas, Arkansas, Minnesota, Oklahoma and Florida.

A thunderstorm in Minnesota spawned a tornado near the town of Benson.

Showers and thunderstorms were scattered across the upper Mississippi Valley, with the strongest stretching from Iowa into Wisconsin.

The northern Rockies and the central Pacific Coast also got rain Monday, but skies were fair from the Carolinas to the northern Atlantic Coast.

Thunderstorms were forecast in Kansas, western Texas and Oklahoma today after tennis ball-size hail fell in Garden City, Texas, and golf ball-size hail dropped on the Texas town of Dryden and Swan Lake in Arkansas.

A thunderstorm hit Minneapolis-St. Paul early today.

Skies were cloudy in Miami; Fort Worth, Texas; San Antonio; Fairbanks, Alaska, and Las Vegas.

Temperatures climbed Monday into the 90s in North Dakota, Minnesota and Texas. The nation's high was 94 in Presidio, Texas.
