Temperatures that were stuck in the 30s this afternoon managed to help deliver the first below normal day since mid-December. Wind chills that peaked in the 20s in most spots are dipping again with sunset. Those winds will be subsiding somewhat as we head into tomorrow, but temperatures stay on the chilly side.

The streak is over: With an average (so far, it may drop) of 35 degrees, today is the first day since Dec. 12 that temperatures ended up below normal in the city. The normal temperature today is 35.8 degrees, close to the coldest of the year at 35.7, which comes on Jan. 15-16. The four weeks of above normal temperatures ends up the longest wintertime streak since 2006-2007, when 30 days of above normal readings happened over almost the exact same period.
