Merry Christmas to all of you! What a beautiful day with highs well into the 50's. Several waves of low pressure look to knock down temperatures over the upcoming week, but nothing will compare to a monster trough that's forecast to ring in 2008.





Notice the plunge of 850 temperatures. We're talking -12 to -13 degrees Celsius at 5000 ft. The GFS does have a cold air bias, so that's something to take into consideration, but it has been showing this cold blast for several runs now. That provides confidence with the cold solution. This cold air mass would likely mean highs in the 30s and lows in the teens! We'll have more on the cold air as we gather new information.
