It has been really cold here the last couple of weeks and it looks like that trend will continue through at least the first week of 2014. A really cold air mass will be building in Canada and eventually dive southward into the Eastern U.S. which could bring widespread subzero temperatures to more than a dozen states in the north and could make it as far south as Kentucky and Oklahoma!! Check out the mass of cold air that rolls in from Canada. The first image shows 850mb temperatures for Saturday to show some minor warming followed by the second image which is for Monday afternoon.
Look how cold it looks and just how far south it gets… ridiculous and something you only see in the month of January.
The Climate Prediction Center (CPC) seems to agree with the current forecast computer models. Check out the temperatures expected from January 5th to 9th and then from the 7th through the 13th. Remember that the CPC forecast is based on probability and not actual temperatures. So this shows the probability of above, normal, and below normal temperatures for those time periods.
They are forecasting above average chances for below average temperatures during both time periods. They are also showing temperatures to be significantly below average at times… which is temperatures 25 degrees or more below average.
"Much below average numbers" show that several bouts of Arctic air are likely which would keep highs below zero and lows 20 plus degrees below zero. Stay warm!!
