The days around mid-January have long been associated with the proverbial “January Thaw”, when winter briefly loosens its icy grip.
Annual averages really do show a slight temperature increase, and subsequent dip, during the final week of January.
This year winter has not let up. In fact temperatures were anything but warm. The weather got below freezing at times causing building closings etc.
According to farmersalmanac.com, “During the January Thaw, which usually lasts for about a week, temperatures rise an average of 10° F higher than the previous week, then drop back down in time for February’s arrival. Though it’s called a “thaw,” the January Thaw doesn’t necessarily melt away snow and ice during its stay. In areas where winter weather is exceptionally cold, temperatures during the thaw may not even rise above freezing.” Which happened to us. Temperate regions may experience a “false spring.”
According to The Weather Channel, “The January Thaw is considered a singularity, which the American Meteorological Society defines as “a characteristic meteorological condition that tends to occur on or near a specific date more frequently than chance would indicate.”
“Many residents in the north-central and northeastern part of the country have noticed that after a period of cold temperatures in early to mid-January, a thaw occurs around the Jan. 20-24 time frame. This “January Thaw” doesn’t necessarily happen every year, but when it does, it is usually around those dates.” according to The Weather Channel.
