Jac... how does the potential 1066MB surface high north of Alaska (being forecast by the ECMWF) fit into what you think will happen next week? Here is the Dallas NWS mention of it in the final paragraph of their 536 AM CST SUN DEC 27 2009 discussion as copied in the link and narrative below:

FINALLY...A LOOK BEYOND THIS FORECAST PERIOD SUGGESTS WE WILL NEED TO KEEP AN EYE ON THE FATE OF AN EXTREMELY COLD AIRMASS THAT WILL BE ORGANIZING IN NORTHERN CANADA. GFS/ECMWF FOR SEVERAL DAYS HAVE BEEN BRINGING A POLAR VORTEX FROM SIBERIA ACROSS THE NORTH POLE INTO THE CANADIAN ARCHIPELAGO. GFS KEEPS THE COLD AIR BOTTLED UP...BUT THE ECMWF FOR A COUPLE DAYS HAS BEEN INDICATING A GOOD UPPER PATTERN TO ALLOW THIS AIRMASS SOUTHWARD JAN 5-8. LAST RUN OF
THE ECMWF HAS A SURFACE HIGH OF 1066MB NORTH OF ALASKA...WHICH IS THE HIGHEST I HAVE EVER SEEN THAT MODEL FORECAST.
