Antarctica Temperature Satellite
The 3AM UTC image is where it is obvious there was a huge movement of frigid air off the top ice. It's noted to only be -10 C to - 20 C. The -20 was directly over the Polar Plateau.

Antarctica Wind Satellite (click here for animation)
Noted the diminished winds throughout the continent except for the areas where the high disturbance was noted in the jet stream. The transcending air mass due to the change in temperature which caused the temperature over the Blue Ice 'fell' off the three mile high ice to the surface thus resulting in high winds in those locations.

Antarctica Jet Stream (click for 1 week loop) It's pretty clear the arrival of heat transfers and the absense of them. The most significant disturbance is noted arriving on October 25, 2007 at 2 o'clock and continues to circulate to the current 6 o'clock position.
Noted significant disturbance that forced the frigid air mass over the Blue Ice to diminish in capacity of coldness to counter the warm air arriving at 6 o'clock and another approaching at 8 o'clock.
