Temperatures as whole ran below normal at night with the many clear and dry mornings we saw during the month, but daytime highs were 4 degrees above the average. This daytime warmth offset the night-time coolness, so the month ended up 1 degree above normal, which is not a lot.
When all the numbers are crunched, October 2010 in Texoma ended up slightly warmer than average and much drier than average. This a typical La Nina conditions and I expect similar numbers for November: drier and warmer than average, with several bouts of cold nights.
