Has anyone ever seen something as insane as this--a 1066 mb ridge of high pressure in the forecast?? From this morning's Dallas/Ft Worth NWS forecast discussion . . .
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.
