This is shaping up as a very warm year.  January was about 6 degrees warmer than average, and February came in nearly 5 degrees above normal.  March was an incredible 11 degrees above average (probably our warmest March ever recorded), but April actually fell to about a half degree cooler than normal.  May put us back on the hot side with temperatures more than 6 degrees above average; the National Weather Service in Pittsburgh called it their warmest May since 1944!

Our average high in May was 78.4 degrees, 6.5 degrees above average, and the average low of 55.1 degrees was 6.2 degrees above normal.  We set three daily high temperature records, with 87 degrees on May 25, 88 degrees on May 26, and 90 degrees on May 27.  The hottest day of the month was 91 degrees on May 28, just one degree shy of the record.  The coolest reading of the month was 38 degrees on May 17.

There was close to normal precipitation in May, although rain only fell on 9 days during the month.  We recorded 3.34 inches of rain in May, a quarter inch below the average of 3.59 inches.  No daily rainfall records were set, but we did pick up 1.55 inches of rain on May 8, by far the wettest day of the month.  Severe weather was relatively rare, with only three days noted during the month (May 1, May 27, and May 29).
