White Christmas? Probably not ...
From The Sun's print editions:Baltimore Sun reporter Candus Thomson offers this guest post:
Chances of a white Christmas this year are about as good as the Orioles making the 2012 playoffs, gas prices dipping below $3 a gallon or Donald Trump sporting a mohawk.
Based on history, the National Oceanic and Atmospheric Administration puts Baltimore’s chance at 10 percent. Ditto the Farmer’s Almanac. The Weather Channel’s long-range forecast shows daily highs at about 50 degrees going into the holiday weekend. For a better than 50-50 chance, travel to northern New England or the Great Lakes region.
UPDATE: Here's what Baltimore professional meteorologist Eric the Red has to say about Christmas weather:
"After looking like we would get colder and stormier for the end of December, models are backing off almost entirely of this idea. The north Atlantic high is now forecast to be farther south, making it the non-north Atlantic high ... and now, the models show a continuation of a low over Greenland. Classic North Atlantic Shop Vac -- the low to the north spinning counter clockwise, while the high to the south spins clockwise, and in between, a very fast west-to-east flow aloft -- sucking all the cold air out of North America. We've avoided this for the last 2 winters (we've had a blocking high over Greenland or thereabouts), but I'm beginning to suspect it may end up being our fate this year. ... If indeed this continues, we will not only see below-normal snowfall, we may struggle to get any snow at all. ... El Nino and La Nina play a role, but for us, the money is in the North Atlantic Oscillation, which is essentially what we're talking about here."
