C-U goes 750 days without subzero reading
CHAMPAIGN — For the third consecutive month and the 11th of the last 14, February temperatures in Champaign-Urbana were above average — but just barely.
The mean temperature last month was 29.8 degrees, while the average February mean is 29 degrees.
Meanwhile, February was without a subzero temperature reading, meaning that it has been 750 days (including Monday) since Champaign-Urbana has had a below-zero temperature, according to Jim Angel, state climatologist at the Illinois State Water Survey. By the end of this week, the current streak will be the second-longest in local weather history.
Currently No. 2 is Dec. 25, 1951, to Jan. 16, 1954 — 754 days without a subzero reading. Subzero readings in Champaign-Urbana in March are rare, the last one occurring on March 5, 1960.
The local above-zero record — set between Jan. 24, 1937 and Dec. 30, 1939 — is 1,071 days, according to Angel.
The last subzero temperature in Champaign-Urbana was on Feb. 10, 2011. In order for the local record to be broken, temperatures in Champaign-Urbana would have to stay above zero through Jan. 21, 2014.
