Record Heat in Rochester Could Be Followed by Severe Storms
Rochester, MN (KROC-AM News) - Rochester is included in a flash flood watch posted by the National Weather Service. It takes effect at 7 AM Tuesday and will remain in effect until 7 AM Wednesday. That follows a day with record-setting heat. The unofficial high temperature at the Rochester Airport this afternoon hit 88-degrees. That's 2-degrees above the previous record high for September 30th set in 2002.
Monday's record-breaking and tropical moisture from the Gulf of Mexico being pushed into southeastern Minnesota is expected to spark storms and dump heavy rain on the already saturated soils in the region. The result could be flash flooding, along with mud and rock slides in bluff country. At this point, forecasters are saying most areas should see 1 to 3-inches of rain with higher localized amounts possible through Wednesday.
The National Weather Service is also advising that southeastern Minnesota is included in an area facing an elevated risk of severe weather tonight and into early tomorrow. The main risk will be for damaging winds, large hail, and isolated tornadoes with the highest risk expected between 9 PM and 3 AM.
