Anomolies and Other Chilly Questions
With the end of this cold snap in sight, here is an update of the standardized daily temperature anomalies plot through Friday. Every day since Nov 10th has been below normal and yes indeed, Monday was the most anomalously cold day of the year; the mean temperature of -35F was 2.29 standard deviations (SD) below normal, just edging out May 2nd, which was 2.26 SD below normal. The warmest day relative to normal was September 21st; at 2.13 SD above normal, it's the only day this year to be more than two SDs above normal. A cold snap trivia question: Friday was the 14th consecutive day with a maximum daily temperature 0F or lower. What's the longest consecutive streak of days a maximum daily temperature 0F or lower in Fairbanks?
