Pattern Change...Colder Air Comin'

January 11, 2008

  

 It’s been a week of seasonably cold nights with above average daytime highs. This pattern should continue through early next week.

  

 Changes are on the horizon, though. All computer models are pointing to a surge of arctic air arriving by January 16th. The map at the left shows the expected

18,000’ wind pattern for Wednesday. This particular level is the one that tends to be the most reliable indicator of the  “steering” for large storm systems and cold air masses.

  

 Temperatures are expected to tumble behind the front. I’m not predicting extremely cold overnight lows due some cloud cover. Fewer clouds would bring lows down into the teens; a more robust system might set us up for some ice or snow the middle of next week. Either way, daytime highs should be about as chilly as the cold snap just before Christmas.  Brrr!

  

 We’ve got some time to watch this…but bottom line…enjoy the mild days, as much colder readings are expected with this pattern change.

  

 Take Care….
