      1-21-2013: Coldest in Years

      Temperatures stayed below zero over much of western Upper Michigan today. This is the first day that it has stayed below zero in over three years. The last time this feat was achieved was January 15, 2009 when the high at the National Weather Service (NWS) only reached 1 below. The core of the coldest air pushed in last night. Here are some of the coldest low temperatures in Minnesota:


      In the Upper Peninsula, lows reached into the teens below zero at some western interior locations including 16 below at Ironwood and 14 below at Champion and 17 below at Peavey Falls in Iron County. A stiff breeze along with some clouds kept the temperature from going as low as it did back in 1984 on this date. It hit 24 below zero at the National Weather Service (NWS) site near Negaunee. The high that day was only 2 above. The bitter cold made a return engagement after leaving at the beginning of the year. Some of the coldest air on record plagued Upper Peninsula shoppers and holiday revelers just before and during the Christmas season in 1983. It hit a record-shattering 28 below zero on December 20, 1983. Temperatures went below zero on 12 of 15 days to close the month.

      January 1984 featured 14 days below zero with a mean temperature over three degrees below average. When February began, the temperature went above freezing. It was a foreshadowing of what the rest of the month would bring. By the second week of February, temperatures went well above average and stayed there. Between the 8th and 23rd, there were 15 days above freezing, with a maximum of 57 degrees on February 22nd. A rainstorm occurred on February 12-13. The month ended 11 degrees above normal. Winter wasnâ??t over though; it made a huge comeback in March with subzero cold the first half and a huge U.P.-wide snowstorm during the third week of the month.

      Our current cold will stay through the week. Tonight some interior locations, especially over the western U.P. will approach or even exceed 20 below zero. However, the core of the coldest air is over us now. There will be a slight moderation at mid-week and a more substantial warm up over the weekend. Outside of lake-effect, little snow is expected.
