Late summer is a time of transition: the nights are getting longer; the hottest part of summer has passed (on average) and football season has returned.
However, it’s not very often to see a pattern quite as mild as the one on hand this weekend and into next week. A deep upper trough and strong surface high pressure will serve to displace the usual humid air to the south.
This will allow us to have some very pleasant late summer weather into the last week of August. Lows should run in the 60s with a few 50s possible in the colder valleys of southern Oklahoma. It will be warm during the day, but with low relative humidity it should be quite comfortable to be outside.
