Will this December be the warmest one on record?
Trung, This will of course depend on how the rest of the month turns out. The highest December mean temperature is 10.4F in 1914 and the warmest modern era December is 7.6F in 1985. Through the 18th the average temperature has been 12.9F. So to beat 1914 it would have to remain about as warm as it's been the next 12 days, while to exceed 1985 it could cool off some. Of course, even two or three days of -30s would knock down the monthly average by a fair bit. Models are no help in this case as they are all over the place for temperatures during the next two weeks.
Trung,The numerical models have now (Tuesday morning)come around to agreeing on a major pattern change late this week, with very cold weather next week. This would mean no record warm December, though at this point it is probably too late to be anything other than "significantly above normal". Rick
