Colder Look and some Rain in the Extended Forecast

I expect to see a colder look over the next week or two with the NAO forecast to go negative. I briefly discussed NAO in yesterday's post. I have fairly good confidence in a dynamically driven (Cold Front) rain event Mid/Late next week. The Ensemble Prediction Systems (Many different versions of a model "tweaked" with different physics) are in good agreement for a colder look and the NAO is negative; I don't see why that wont come to fruition. I am concerned for recently planted corn, not for a freeze risk, but more so from a soil temperature standpoint. 

I'll post tomorrow on the Severe Weather Risk for this weekend.
