About 1/2 of the local weather stations that are in the network I am involved with have not reached 32 this season yet. Wed AM is a legit chance. Not sure if MDT (Canadian says yes, others not so much) but outside the HIA areas it may be more likely. It is actual cold air provided via a trough and not radiational based as some of the other cold snaps have been. So, elevation finally has a shot.
