Here's an update of daily mean temperatures in Fairbanks for 2013. As usual, the gray shading is plus or minus one standard deviation from the 1981-2010 mean. Although Wednesday was the warmest day of the year thus far, with the first 50ºF max temperature since October 7th and a daily mean of 36ºF, this was still 1.6 standard deviations below normal. The 215 days with a high less than 50ºF is the fourth longest such streak, although more than two weeks shorter than the 1963-64 record.
Watch the bouncing ball of 500-hPa height anomalies of cold Canadian air over Alaska from early April to early May.
