UPDATE: Thu 27 Feb 2014 / 10:30 p.m.
Ice is looking more likely for Sunday as the cold air is speeding up in the model output. Frigid air masses' forward speed is often underestimated by computer models, and then they start to cue in on the pattern about 60 to 72 hours out. This is exactly what happened Thursday night, so I am now more confident Texoma will have some type of ice event Sunday. The intensity of this event is uncertain, but it will definitely be very cold with a high chance of precipitation (70%).

===================Original post on 26 Feb=================
Winter hangs on in the new month of March: another batch of very cold air over the Great White North heads our way this weekend.
The polar vortex we’ve heard so much about this winter will be positioned over Hudson Bay and the flow around its western side will interact with a building upper high to dislodge this cold air:
This upper-air pattern gives it a good shove southward over the weekend:
The leading edge of the air mass, an arctic front, is expected to pass on Sunday morning with the possibility of cold rain that may change to sleet or snow before ending later in the day Sunday.
Maximum temperatures for the first week of March will be some 20 to 30 degrees below the average. In fact, the upper air flow could push another surge of northern air our way March 7 or 8th.
The abnormally cold winter of 2013-2014 continues.
