The cold air, as indicated by the following NOAA forecast map for Tuesday’s high temperatures, is beginning to make inroads back into the northern part of the United States. The question many of us have is whether it will return to the intensely cold pattern of December into the first half of January, or whether this new shot of cold air will be a glancing blow in our march toward spring.
Cold to Return for East and South
According to the coupled forecast system (NOAA long-range computer forecast model), it will be somewhere in between–cold in the South and East, but the cold will not be as extensive across the country or as intense. (Note: The February 2010 forecast is indicated on the map in the upper-left in the following image.)
