I don't know if anyone has already started this. But parts of the SE US is forecast to experience its most brutal Arctic blast in 5-9 years, depending on the model. While they differ on the coldest morning, both the GFS (Fri am) & Euro (Sat am) forecast Birmingham to drop to 5-8 F/-15 to -13.5 C in this extreme cold event. The local guys are predicting 10-11 F/-12 to -11.5 C, but the models keep showing Temps under this.
