Happy New YearDecember 31st, 2012 at 8:56 pm by Bill Steffen under Bill's Blog, Weather
Happy 2013 everyone! Hope it’s your best year ever! Thanks for reading my blog. I’ll update this, but some preliminary climate notes: December in G.R. looks to be 5.9° degrees warmer than average with an average temperature of 35.1°. The month was 5.6° warmer than average in MKG and 5.2° warmer than average in Lansing. We had 2.72″ of precipitation in G.R., which is 109% of average. The average wind speed was 9 mph and we had roughly 17.5% of possible sunshine (average is 20%). We had more minutes of sun from 2 PM July 3rd thru July 6th (3 1/2 days) than we had in the whole month of December. We only had 5 days all month that were more than 1/3rd sunny (33%). Snowfall in December in G.R. was 7.2″ in G.R. Most of the Lower 48 states were warmer than average in 2012 (Detroit +3.6°, Dallas +3.1°, Oklahoma City +2.7°, Cincinnati +2.7°). There were a few places that were near or cooler than average (Miami +0.1°, Seattle -0.3°, San Francisco -0.6°, Honolulu -0.5°) and most of Alaska had a cool 2012 (Anchorage -2.7°, Juneau -1.9°, Fairbanks -2.5°, Nome -3.7°). NASA IR global temperature anomaly (current 1981-2010 average base) has the Earth at +0.039 degree warmer than average in 2012, with much warmer than average conditions over much of the Arctic and North America and cooler than average temperatures over Alaska, central Asia and a significant part of the Southern Hemisphere. December Global Temperature Anomaly shows the globe was pretty close to average, with warmer than average over the Eastern U.S., Eastern Canada, and the Poles – colder than average over Western Canada, Alaska and much of Central Asia.
