Saturday Was Another Record-Breaking Day

While many thermometers - including the Blaine airport - saw highs at or above 100F on Saturday, MSP airport missed it by *holds fingers close together* that much. The high at MSP topped off at 99F, setting a new record for the day as the previous record was 92F. Several other locations across the state saw record highs, with records in the 100s out into South Dakota.

Here are all the airport locations across the state that were able to hit 100F. The warmest high was out in Madison, where the thermometer reached 106F. However, it was a dry heat, as the peak heat index value there was only 102F.
Meanwhile, there was a big temperature drop in Duluth along Lake Superior this afternoon as the winds shifted from the west to the northeast, with the temperature dropping 33F in 20 minutes!
