TEMPERATURES WILL TAKE A PLUNGE AS A VERY CHILLY AIR MASS MOVES IN ON MONDAY… IN THE MEANTIME, THE WEEKEND WILL BE ABOVE NORMAL WITH DRY CONDITIONS

2011 will end on the mild side but Old Man Winter is getting ready to show his muscle with dropping temperatures early next week.  By Tuesday, high temperatures will probably not rise above the 30’s. Winds will be a factor, also. Does this mean that the mild weather pattern is over? I don’t think so. Temperatures are expected to moderate later next week. One factor that can create a very cold and sometimes stormy weather pattern here in the eastern part of the nation is a blocking pattern. One example of a blocking pattern is a large high pressure system over Greenland that is basically stationary. This high causes the upper-level winds (or the jet stream) to buckle and become more amplified over North America. Upper level winds then blow from Northern Central Canada south to the Gulf Coast and then turn back northeast along the East Coast. This pattern normally with the deep trough just to our west creates huge snowstorms along and near the East Coast. We haven’t seen that this year which is very different from last year, which was very stormy and cold. This year, the Arctic air masses have been locked in northern Canada. There are other factors that play into creating a stormy weather pattern such as the Artic Oscillation phase. You can search for that on the Internet for more information to better understand this climatic pattern…. So, enjoy the mild weather while it lasts and Happy New Year!
