Despite a gusty southeast wind the temperature did not rise above the freezing point until late afternoon. At 5 P.M. it was still 32 degrees but by late evening had soared to 47 degrees. The temperature dropped very sharply early today when the cold front passed with an 11-degree drop recorded in just ten minutes just after midnight.
