Tis the season. (!) is the low tire pressure warning signal. From an earlier discussion, Q45Tech estimated that the tire pressure will drop 1 PSI per 10degrees in ambient temperature. So tires that you set at 32PSI when it was 80F outside would be 29PSI at 50 degrees.

My wife could almost predict the outside temperature by if the (!) came on in the morning until I got around to adding a few PSI. I set all of hers around 35PSI cold on a 50 degree day so that there's some room for error on cold mornings... You need to check them every couple of weeks anyhow - there's no such thing as a completely air tight tire/wheel combination.
