Daily Climate
Posted: 16 Jan 2015 05:42 AM
Our current rebound in temperatures to levels well above freezing are certainly a nice
break from the recent few weeks of cold weather. Climatology says that the middle of
January is the coldest time of the year, but climatology can be computed different ways.
The featured chart presents three daily temperature climatology metrics. The National
Climatic Data Center (NCDC) produces 30 year normals which are updated every ten
years. The chart shows the most recent two iterations of that product as well as the simple
daily average of long term observations. The 1971-2000 product was provided in whole
degree Fahrenheit, so that is why it jumps up and down on the plot. It is interesting to note
the difference between the 1981 product and the other two metrics.
