Maybe pretty chilly mid-week next week?
I was hesitant to post this, because it is still very questionable. However, the European model is showing a pretty good shot of cold air down the Plains in about 8 days. It is very much in doubt how far south the truly cold air will come, and there isn't a lot of support yet from other models. But the current output from the European would likely cause some frost in a large part of Oklahoma.
I'm not posting the because I think it is going to happen. I did it more to recommend you don't put away any of the cold weather protection. Or if you did, just be prepared to bring it back out some time next week.....just in case.
Also, Sunday could be a really bad severe weather day in central/eastern Oklahoma. If the current model trends hold, there could be lots of fireworks.
I'll try to post updates in the next few days.
