If you'd like to get a feel for fall, today's the day.

Rain is likely for a good chunk of Sunday with overcast skies keeping the expected highs in the upper 70s.

The rain delayed the start of the St. Louis Art Fair in Clayton by an hour on Sunday. It now opens at noon.

If you're not done with summer yet, it returns for the work week. Monday should be mostly sunny with a high near 91, then a chance for afternoon showers on Tuesday and a high n ar 93.

It's more of the same for Wednesday and Thursday with sunshine and highs in the 90s. 

And if you're waiting for autumn, it arrives on Monday, Sept. 23.
