Description
Summary:Repeated outbreaks of arctic air kept the eastern half of the Nation several degrees lower than normal; but in much of the West, relatively mild weather prevailed for the seventh consecutive week. The upper level flow pattern of a ridge in the West and a trough in thc East was similar to the pattern of the minter season. This high-amplitude flow caused the freezing line to reach the Gulf of Mexico and well into Florida each week this month; the 0°F isotherm went as far south as northern Georgia. New record temperatures for the month included 27°F at Sault Ste. Marie,, Mich., and 81°F at Goodland, Kans. The only other records of note came from Lakeland, Fla., with November to February the coldest 4-mo period of record and from the San Francisco, Calif., city office with the warmest December to February of record. Dryness in the West broke February records at Denver
