May Notes...

     Flip the coin... After April was 3° below average, May was 3° above.  The big story was the lack of rain....

    Of the eight days that received recordable precipitation, three of them were 0.01”.  The two ‘biggest’ storm systems dropped 0.32” and 0.31”.  Rain coming in under one inch was a shock to me, but it should not have been because it made it easy to bike every day of the month.

    On the temp front a few notes: the lack of rain, therefore cloud cover, allowed warmer daytime temps but also cooler nights.  Note the difference comparing this month to the average.  Also the cooler nights would keep down the cooling degree days, even if daytime temps were quite warm.

    There were 2 record highs set this month, and no record lows. Through May the count for this year is 7 record highs and 6 record lows.
