I know the weather in the Ozarks can be variable, but…
There’s a cold front on it’s way and according to the OEM Extended outlook:
There is a 50 degree difference between the warm and cold sides of the front. The slow moving front is projected to make it to US 65 by sunrise Wednesday (04-10-13) morning.
Of course as Ginger points out, that’s the temps up in the clouds. It’s still a big difference though!
