GFS ensembles are forecasting brutally cold air to come down from the south in droves as Old Man Winter aims to make his presence known. Most of the ensembles are showing extremely cold air, while others show not as bad temperature anomalies but still well below average across the board. The 12th ensemble in the mix (counting from right to left) breaks the lowest this legend can go for below normal temperature anomalies. That's right, that ensemble member has temperatures forecasted to be at least 42 degrees below normal. That would certainly go below 0 degrees Fahrenheit. However, this is hour 240 of the forecast, considered long range. We will monitor this prospect however, and keep you informed nonetheless.
