WARMEST OF 2014

It took 178 days and in that span we dealt with: over 30 tornadoes, 4.5 feet of snow, bitter cold of -15° and wind chills of -40°,  but we finally reached the 70° mark Thursday afternoon.  As first foretasted last week, the official high of 74° is the warmest here since mid-October (October 13 71°).  The stretch of non 70° warmth is one of the longest on record, ties the 1937 stretch of 178 days as well.  The longest spell of non 70s – came in 1958 with 189 days.

Gusty southwest winds of over 40 mph ushered in the warmth, a wind shift to the northeast is expected around 11 pm in the city, winds will subside later tonight and overnight.

A strong cold front passes late Sunday night into Monday morning bringing more rainfall and a sharp drop in temperatures.  Late season cold air spills in through the day dropping early morning temperatures in the 60s down to the 40s by the evening commute.  Lingering moisture could allow some of the rain to mix with wet snow late Monday or early Tuesday with  afternoon temperatures likely to remain just below 50° Tuesday and Wednesday
