November 5 - Record high temperatures


Several locations across central and western Wyoming either tied or broke record high temperatures on Thursday, Nov. 5, when an unseasonably mild southwest flow, snow-free basins and enough wind to mix out the the valleys and basins pushed temperatures into the 60s to lower 70s.


No records were broken in Big Horn County, though temperature sensors at the Greybull Airport recorded a balmy 64 degrees on Nov. 5, then heated to 70 degrees on Nov. 6.


The following table, provided by the National Weather Service, shows locations that reached or exceeded record highs (orange), and also some locations that came close to record highs today (yellow):

The warm weather follows a brutally cold October in Wyoming. Most notably, Casper experienced the coldest October on record (since 1939) with a month average temperature of 37 degrees, which is 8.7 degrees below normal. Several other cities including Riverton and Lander had near record-cold Octobers as well.  


What is the cause of this abnormal weather?  Could it be global warming or is it just a few days of fluke temperatures? What do you think?
