Summer-like air to stay as we enter the final days of September

While Monday marked the seasonal transition from summer to fall, it has felt anything but fall-like here in the Stateline the past 2 weeks. 

That trend is not only set to continue this weekend, but also into the final days of September. 

Now, we do have a cold front sweeping through this morning, which will leave highs somewhat cooler in the upper 70s. Compared to late-September standards, this ends up 4° above-average.  

 

 

Cloud cover hangs tight and with that cloud cover may come a few showers and thunderstorms. Unlike Monday, any thunderstorm that does manage to form will showcase non-severe characteristics. Overnight low temperatures will end up a smidge cooler in the upper 50s. Some may even wind up in the mid 50s IF a fog layer can become established. If so, you may need to give yourself a few extra minutes for travel for tomorrow morning's commute.

On the backside of today's cold front, low pressure sweeping to our south will keep surface flow out of the northeast, so off Lake Michigan. This will help bring afternoon highs down closer to average for not only Wednesday but also Thursday. Depending on the northern extent of the precipitation shield, we could see a few showers Wednesday. 

The midweek cooldown is brief as summer-like air makes a quick return for the weekend. There is a cold front that forecast models bring in during the first half of our Saturday. However, there isn't much cool air that comes along with it, which will leave afternoon highs near 80° into next week.
