Temperatures have now begun to normalize, but we did go through a cold stretch of weather at the end of last week through Saturday morning. During this time period, both high and low temperatures were about 20º below average. The coldest period came Friday through Saturday morning when we were cold enough to break some records.
High temperatures on Friday barely reached the lower 50s. Officially, Rochester warmed one more degree from the temperatures shown below, but a high of 51º was enough to break the coldest high temperature record for September 12th. The previous record was 53º set in 1989.
Thanks to clearing skies Friday night, Saturday morning temperatures were downright cold. Lows even dipped below freezing for Mason City breaking the record of 34º set in 1963. Austin and Rochester both came within a degree or two of the record but did not break a record.
The cold weather we felt on Friday and Saturday was more similar to temperatures at the beginning of November! It certainly helped a few leaves in our area begin to change colors. Most leaves throughout Minnesota are just beginning to change, but something to keep an eye on over the next few weeks as the changeover begins.
If you did not enjoy the cold weather, then you will be happy to hear a nice steady warm-up will continue all week. After highs in the middle and upper 60s Saturday and Sunday we start Monday a little cooler thanks to morning showers. From Tuesday on our temperatures warm back into the upper 60s and even above average in the middle 70s by next weekend. We have a few nice, dry days for the middle of the week with a nice shot of rain setting up for the beginning of the weekend.
