Preliminary climate summary for December 2013

Preliminary climate summary for December 2013
Clearly the coldest month of December statewide since 2000, this month brought average temperatures across the state that were 7 to 13 degrees F colder than normal, with many nights well below 0 degrees F. Some communities will report average monthly temperatures for December that fall within the coldest ten historically. Some of these locations include:

International Falls 3rd coldest
Mankato 4th coldest
Grand Rapids 5th coldest
St Cloud 6th coldest
Duluth 8th coldest
For the Twin Cities, an area greatly affected by the urban heat island, December of 2013 will rank 17th coldest (back to 1871), and for Rochester it will rank 14th coldest. On a statewide basis it appears that December 2013 will be ranked as the 7th coldest in history (back to 1895). Extreme values for the month ranged from 48 degrees F at Pipestone on the 3rd to -35 degrees F at Embarrass and Babbitt on the 24th and at Hibbing on the 8th.

Happy winter solstice!

HAPPY WINTER SOLSTICE! The winter solstice will occur Saturday morning (Dec 21), officially, at 11:11 am CST. At that time, the earth's spin axis will be oriented so that the sun appears to be the farthest south in the local sky (midday over the Tropic of Capricorn in the Southern Hemisphere). While most of us consider this event to be the start of astronomical winter, the British call this day the "Midwinter Day", as the apparent sun will begin its northward climb again, back toward the equator. For essentially all locations in the Northern Hemisphere, Saturday night will be the longest of the year. On a brighter note, starting Monday the length of darkness will begin to shrink as we head toward the summer solstice on 21 June 2014.
