September 21 Last Warm Summer Day: Cool Down With Fall Thursday
September 21, 2022
Wednesday Morning Update
Today may be our last very warm day of the year… At least it will be closing out the summer season. Tomorrow a cold front will arrive on time with the start of Fall. The autumnal equinox is at 9:03 PM, and by Friday it will definitely feel like it.
The cold front will come with some showers as soon as sunrise, then a nice start to the weekend, but another push of colder air will come with more showers and cooler air next week.
