yep shaping up to be a cold first 2/3 of March..reminds me somewhat of March 2011 which was brutally cold.

A large extratropical cyclone located over Ontario has an associated cold front that extends all the way down into the Deep South and Mexico. H/t MV

Massive cyclone; central pressure in Canada now down to ~964 millibars

Still on track for the Arctic plunge

Apparently 850mb temps down to -45C under the Trop. vortex represents historical cold for March. The tropopause at Resolute was at 493mb

Brutally cold!  Looks like spring is very much on hold up north.

On the other side of the coin, there is some pretty big heat being drawn up into the SW corner as the subtropical ridge re-establishes with temperatures in the mid 30s this week, and well into the middle of next week.

It's the time of year when these huge contrasts between the advancing heat in the south and retreating cold in the north collide to give the spectacular storms and tornadoes, some of which have already materialised.
