(UNDATED) - Tuesday's thunderstorms and tornado warnings prompted many to wonder why Indiana was having unusual weather.
Meteorologist Jason Puma of the National Weather Service in Indianapolis says spring-like storms in winter are not all that uncommon in the Plains states because of warm influences from the south and cooler temperatures from the north.
Puma says Indiana has had reports of tornadoes every month of the year. There were no reports of a tornado touchdown in the area as of yesterday.
The National Weather Service in Louisville, Ky., confirms a line of storms that raked Indiana spawned a weak tornado that struck an airport in the Ohio River city of Madison and damaged an airplane.
The tornado rated EF-0 had wind speeds of 85 mph and was 60 yards wide as it traveled about a third of a mile over less than a minute at Madison Municipal Airport. It moved an airplane and broke its nose gear and damaged a hangar and an operations building.
An EF-0 also hit in northern Clark County damaging a Wal-Mart and an EF-1 hit in Floyd County with wind speeds of 95 to 100 miles per hour.
The winter thunderstorms occurred ahead of a front bringing sharply colder air and a temporary end to mild temperatures.
