...A COOL AND WET MAY...

METEOROLOGICAL SPRING CAME TO AN END WITH A RATHER COOL AND WET MAY.
MEASURABLE PRECIPITATION FELL ON NEARLY HALF OF THE DAYS IN THE
MONTH AND TEMPERATURES WERE BELOW NORMAL ON 19 DAYS. THE AVERAGE
DAILY TEMPERATURE WAS AT OR BELOW NORMAL FOR THE FIRST 9 DAYS AND 6
OF THESE DAYS WERE 10 DEGREES OR MORE BELOW NORMAL. THERE WAS A NICE
STRETCH OF WEATHER FROM AROUND THE 14TH THROUGH THE 18TH WITH ABOVE
NORMAL TEMPERATURES AND NO PRECIPITATION. THIS BRIEF WINDOW DID
ALLOW MANY FARM FIELDS TO DRY OUT WHICH GAVE FARMERS A CHANCE TO GET
THEIR SPRING CROPS IN. UNFORTUNATELY THIS WINDOW CAME TO A QUICK
CLOSE AS MORE RAIN RETURNED WITH OVER AN INCH FALLING ON THE 19TH
AND 20TH COMBINED.

THE AVERAGE MONTHLY TEMPERATURE WAS 56.8...2.5 DEGREES BELOW NORMAL.
THIS RANKED AS THE 35TH COOLEST MAY ON RECORD. THE HIGHEST
TEMPERATURE WAS 85 ON THE 16TH AND 18TH AND THE COOLEST TEMPERATURE
WAS 28 ON THE 8TH. THERE WERE 3 DAYS DURING THE MONTH WITH A LOW
TEMPERATURE BELOW FREEZING.

MONTHLY PRECIPITATION WAS 4.92 INCHES...1.09 INCHES ABOVE NORMAL.
THIS RANKED AS THE 33RD WETTEST MAY ON RECORD. MEASURABLE
PRECIPITATION FELL ON 13 DAYS AND A HALF INCH OR MORE OF RAIN FELL
ON 4 DIFFERENT DAYS.
