Spring And Winter In One Month


With the arrival of very cold arctic air tonight, January 2007 is shaping up as a month of big contrasts. The first 16 days of the month had an average temperature of 47.1F, an amazing 14.7F above normal for better than two weeks! Pending the final numbers from tonight’s cold blast, the period from January 17th through the 25th has had an average temperature of about 31.1F. Now that’s just one degree below normal for those nine days, but compared to the way this month started, dropping the average temperature by over 15 degrees is fairly dramatic. The extended outlook keeps the cold locked into the eastern United States into at least early February. With El Nino still keeping the southern branch of the jet stream energized, we’ll have to keep a close eye on possible storm developments to our south that would pose a winter weather threat while this cold pattern is in place. The image posted shows the National Weather Service Climate Prediction Center 8-14 day temperature outlook for the U.S., covering the period from February 2nd through the 8th. Below normal temperatures are expected in the blue shaded areas east of the Mississippi. Bundle up!
