Up and to the Right

With temperatures struggling this week well below climatology, it is a good time to check in on what climatology is for this time of year. The featured chart presents a comparison between three climatologies. The NWS official one is currently the green line which represents the thirty year period between 1981 and 2010. The red line was the previous official climatology representing the previous 30 year period. Its values were whole degree, so that is why it is choppier than the other two plotted values. The bars represent the arithmetic average based on period of record data. It is interesting to notice small differences between the three lines. The official climatology is smoothed to remove noisey day to day variability present over just a 30 year sampling period. Regardless of all the above, we should be much warmer today with highs closer to 60 degrees than 40!
