Rochester, MN (KROC-AM News) - Rochester has set a precipitation record.

As of 6:00 AM Thursday, the National Weather Service official recording station at the airport had received nearly half an inch of rain since midnight. That raised the year-to-date total to 43.97 inches. The previous record was 43.94 inches, set in 1990.

Record snow last winter and heavy rain that fell during May, June and July helped set the new record. More than two feet of precipitation fell during the May- July period.

After a dry August, the wet weather returned in September. So far this month, the city has received more than 7 inches of rain - enough to make it into the top 10 wettest Septembers on record.

More rain is expected Friday and Saturday.
