Here is the pattern change in terms of temps at 5,000ft relative to normal.
As you can see will be a big shot of polar air in the central US this week and this will bleed over to the east but moderate a little by this weekend..
As the air arrives it will bring along with it a front later this week which can bring some unsettled conditions Thursday night..
The real concern for rain, however, looks to be this weekend where low pressure will develop along this front and possibly have some tropical influence. This would mean a lot of rain for our area and not a pleasant weekend..
Before we write off the weekend lets wait and see how and if this evolves.
More later this week.
