The unprecedented early fall heat wave that led to the cancellation of the Twin Cities Marathon set another record Monday.
The daily high temperature of 89 degrees tied the same record mark for Oct. 2 set in 1953.
The normal high temperature for the date is 66.
Twin Cities records were surpassed on Saturday, when the high was 88, and on Sunday, when the high was a blistering 92.
The Oct. 1 reading of 92 smashed the 1897 record of 87 and set a new record for the highest October temperature in the Twin Cities — and the hottest temperature ever recorded so late in the year in Minneapolis-St. Paul. (The previous record was 90 degrees on both Oct. 3, 1997, and Oct. 10, 1928.)
The hot, humid conditions Sunday prompted organizers of the annual marathon to cancel the event, given dangers to participants.
Sunday’s heat toppled daily and all-time monthly high temperature records across the state.
According to the Minnesota State Climatology Office, the the highest temperature recorded Sunday by a National Weather Service cooperative observer was 96 at Theilman, followed by 95 at both Milan and Lamberton.
The highest temperature on record for October anywhere in the state is 99, recorded at Ada on Oct. 2, 1922.
Temperatures in the Twin Cities on Tuesday are expected to be in the mid-80s.
Then a cold front is due to arrive, driving highs into the 60s on Wednesday and Thursday and into the 50s on Friday, Saturday and Sunday.
