The Pacific pattern looks great for below average temps during this time period with a huge GOA low/-EPO/+PNA, but without a Greenland block I realy don't understand how that much amplification and phasing can occur in September. We'll see though. Could well end up below average but not well below average.

I'll believe it more if the 12z happens to back it up. -------------------- First Snowfall: Covering on 12/8/09 First Winter Storm Watch:Issued 2/3/10 First Winter Storm Warning:Issued 2/4/10 # of Winter Storm Warnings:2 Biggest Snowfall: 7.5 inches on 2/5&6/10

I'll believe it more if the 12z happens to back it up. The 0z run from last Evening was not as "cold" as previous runs either. The ECMWF is and has been warmer than the GFS. So this may be a product of the GFS coming around to the "warmer" solution like the ECMWF shows.

With another shot behind a second storm a few days later. I figured the 6z was wrong in not even showing a trough coming down during this time period. At least it still shows the next shot at the end of the month like you said. -------------------- First Snowfall: Covering on 12/8/09 First Winter Storm Watch:Issued 2/3/10 First Winter Storm Warning:Issued 2/4/10 # of Winter Storm Warnings:2 Biggest Snowfall: 7.5 inches on 2/5&6/10
