Record Cold Outbreak On or About Jan. 20, 2008?

If the 18z GFS 384 Hour Model run is close to being accurate, we could be looking at some record breaking arctic air for much of the northern half of the United States. 850 Temperatures in Northern Minnesota are forecast to max out a -36 degrees Celsius. This would likely relate to surface temperatures not exceeding the -20's F (or even -30 F) for highs.

If this does pan out, Florida will be in really big trouble with a deep freeze and crop damage/loss and this weeks cold weather with be something they wish they had. Will watch and wait to see if the models are consistent with this or if it will do the flip-flop thing.
