OK, I agree with you that forecasting 2 weeks out is not dependable. For the forecast to pan out, the Arctic high will have to build rapidly, and move southward as the model predicts.
We will see how this situation evolves.
I think that OK or nearby states could be looking at a possible winter storm by the 12th of Dec. You have arctic air moving down into the Midwest with the southwest wind at 850 mb. Maybe even some ice. What do you think ?
