Today may have been the last day that we see 80-degree temperatures in southeast Minnesota and northeast Iowa!
Temperatures will still be warm for the first day of the weekend, but I think the amount of cloud cover will keep the good majority of us in the upper 70s for highs. A few very brief, isolated showers are possible Saturday evening but the majority of us will stay dry.
Temperatures start to drop on Sunday as highs only reach the upper 60s. We'll see partly sunny skies but a few passing showers are possible in the afternoon. Then a shift in the jet stream will bring a big shift in temperatures as we start off the workweek.
A surge of warm air to our west will cause a shift in the jet stream, allowing a strong, steady flow of chilly Canadian air to rush into the Midwest. Look for high temperatures in the upper 50s on Monday and Tuesday, dipping to the low 50s by Thursday and Friday. It's very possible that we see our first hard frost at the end of next week as overnight lows drop to the mid-30s.
Overall, a cool week is ahead of us with a few very isolated rain chances throughout the week. Even though we will be cooler than average to start off the month of October, at least we got to enjoy warmer weather a bit later in the season than usual!
