...A DRY BEGINNING BUT A WET ENDING TO MAY...

MAY BEGAN WARM AND VERY DRY AFTER A COOL AND WET APRIL. JUST A
QUARTER OF AN INCH OF RAIN FELL BETWEEN THE FIRST AND THE 20TH OF
MAY BUT NEARLY THREE INCHES OF RAIN FELL BETWEEN THE 21ST AND 31ST.
THERE WAS ALSO A LACK OF SEVERE WEATHER THROUGHOUT THE
MONTH...HOWEVER A SERIES OF THUNDERSTORM COMPLEXES OVER THE LAST
THREE DAYS OF THE MONTH BROUGHT DAMAGING WINDS AND FLASH FLOODING TO
PORTIONS OF THE REGION.

HIGH TEMPERATURES WERE ABOVE 70 DEGREES DURING THE FIRST
NINE DAYS OF THE MONTH AND HIGHS WERE AT OR ABOVE 70 ON 23 DAYS
DURING THE MONTH. DESPITE BEING A RELATIVELY WARM MONTH...THERE WAS
A LARGE CONTRAST IN TEMPERATURES. THE WARMEST HIGH TEMPERATURE WAS
90 ON THE 20TH WHILE THE COOLEST HIGH TEMPERATURE WAS JUST 50
DEGREES ON THE 12TH. THERE WAS A LOW TEMPERATURE RECORD TIED AS
WELL. THE LOW ON MAY 13TH WAS 30 DEGREES...TYING THE OLD RECORD SET
IN 1996 AND 1928. ON MAY 21ST...A RECORD WARM LOW TEMPERATURE OF 70
DEGREES OCCURRED...TYING THE OLD RECORD SET IN 1911.

THE AVERAGE MONTHLY TEMPERATURE FOR MAY WAS 62.9 DEGREES...3.6
DEGREES ABOVE NORMAL. THIS RANKS AS THE T-21ST WARMEST MAY ON
RECORD. PRECIPITATION FOR THE MONTH WAS 3.25 INCHES...0.58 INCHES
BELOW NORMAL. THIS RANKS AS THE 58TH DRIEST MAY ON RECORD.
