December 2009 weather preview for Grand Rapids

 

December is the month when winter typically kicks into high gear for West Michigan. The Winter Solstice is on December 21st at 12:47 PM. When we have the least amount of potential daylight, only 9 hours sunshine are possible. I say potential because December is our cloudiest month with only 23% of possible sunshine.

December is our second snowiest month with an average of 18.8”; our snowiest month is January, with 20.3”. You may remember December 2008 and all the snow we received. That turned out to be the second snowiest December on record with 54.6”. It was also the fourth wettest with 6.27” of liquid precipitation.

The temperatures continue to fall with an average high of 39° on the first and only 30° by the end of the month. The low temperatures take a similar slide going from 26° down to 17°.
