Not So Normal Temperatures

Here's an update of daily temperature anomalies for Fairbanks through Sunday. At the top is a plot of the actual daily mean temperatures. The gray shading represents one standard deviation from the 1981-2010 normal, so temperatures outside of the shading are "unusually" warm/cold for the date.
The bottom plot is my usual daily standardized anomaly plot, which is simply the departure from normal divided by the standard deviation of the normal temperature for that date. Sunday, at 2.2 standard deviations below normal was not quite the most anomalous day of the year (May 2 was 2.3 SD below normal), but with an apparent high temperature Monday of 32 below, Monday will likely claim that title at midnight.
