It's a Two Horse Race for Hottest June

Here are two ways to look at the temperature for June so far.  In the first, we compare the mean temperature for June 1–22 to similar periods in the past.  This year stands as the hottest such period on record, 0.1ºF warmer than June 1–22, 1918.

In the second, we compare the mean temperature for June 1–22 to that of prior Junes (i.e., June 1-30).  The mean temperature for June so far would rate as the 2nd warmest on record, behind only last June.

Although there's a cool down on tap for Friday and Saturday, we look to rebound again for the remainder of the month.  It looks like a two horse race for hottest June on record between 2015 and 2016.  My money is on the latter.
