Updated Fairbanks Temperatures
Heading into some of the warmest late October weather in years, here's an update of normalized daily temperature departures for Fairbanks for 2013. The upper plot is the daily values, the lower plot the 5-day running mean (to help see the patterns). Recall that standardized anomalies are nothing more than the departure divided by the standard deviation, and makes for an equal comparison across the seasons. This is highly useful in Interior Alaska, where typical variability of cold seasons temperatures is several times greater than the warm season. Each passing day now without snow cover becomes more significant, with daily mean temperatures falling at nearly a degree a day, and it's quite likely that daily departures will exceed two standard deviations later this week,

I'll be interested to see the end of year results...and how closely the area of Red compares with the area of Blue for 2013.

By my count, there have been 38 days in 2013 where Fairbanks has been +/- 2.0 standard deviations from the mean. That is the highest total for any year. Both 1992 and 1975 had 37 such days for the entire year (see: http://ak-wx.blogspot.com/2013/08/most-extreme-year-ever-for-fairbanks.html ). Looks like we'll be adding to that total in the next 14 days.
