...PLEASANT MAY...

FOLLOWING A COOL START TO THE SPRING...MAY TURNED INTO A
PLEASANT...MILD AND QUIET MONTH. OUTSIDE OF A VERY WARM AND WET MID
MONTH PERIOD...MAY WAS COMFORTABLE AND DRY.

THE AVERAGE TEMPERATURE OF 59.8F DEGREES WAS ABOUT THREE DEGREES
WARMER THAN NORMAL. THIS WAS OUR FIRST ABOVE NORMAL MONTH SINCE
OCTOBER OF 2013. THE MONTH FEATURED 7 DAYS OF 80F OR GREATER...WHICH
IS THREE MORE THAN NORMAL. THERE WERE NO TEMPERATURE RECORDS THIS
MONTH.

PRECIPITATION FOR MAY WAS 3.17 INCHES...WHICH IS ABOUT A THIRD OF
AN INCH ABOVE NORMAL. MOST OF THE RAIN FELL IN A 4 DAY STRETCH FROM
THE 13TH TO 16TH...TOTALING 2.38 INCHES. THERE WERE NO PRECIPITATION
RECORDS...THOUGH THE 1.54 INCHES ON THE 16TH WAS TIED FOR THE 12TH
WETTEST DAY IN MAY`S RECORDED HISTORY.

A LONGWAVE TROUGH REMAINED OVER THE GREAT LAKES REGION THE FIRST
WEEK OF THE MONTH WITH COOL DAYTIME TEMPERATURES AND NORMAL
OVERNIGHT LOWS. A PATTERN CHANGE ENSUED FOR THE SECOND WEEK OF THE
MONTH WITH A RIDGE OF HIGH PRESSURE ALONG THE EASTERN UNITED
STATES...AND A WARM FRONT ADVANCING NORTHWARD FROM THE OHIO VALLEY
AND TOWARDS THE NORTHEAST. ON THE 13TH A STALLING WARM FRONT SERVED
AS A BOUNDARY FOR EVENING FLOODING RAINS ACROSS A PORTION OF THE
FINGER LAKES SOUTH OF ROCHESTER...WITH RAINFALL MORE MANAGEABLE
THROUGH THE DAY IN THE ROCHESTER METRO AREA. IT REMAINED MILD
OVERNIGHT AND WAS AGAIN WARM AND HUMID ON THE 14TH AND 15TH WITH
HEAVY RAIN SHOWERS. TEMPERATURES THROUGH THE REMAINDER OF THE MONTH
AVERAGE NEAR NORMAL...WITH QUIET WEATHER CONDITIONS. MEMORIAL DAY
WEEKEND WAS EXCELLENT WITH BRIGHT SUNNY DAYS ALL THREE DAYS OF THE
HOLIDAY WEEKEND.

THERE WAS VARIABLE CLOUD COVER IN MAY AND THE MONTH FINISHED AT 2
PERCENT GREATER THAN NORMAL FOR SUNSHINE. THERE WERE 11 MOSTLY SUNNY
DAYS...AND JUST 6 MOSTLY CLOUDY DAYS. WINDS WERE MODERATE DURING THE
MONTH AND SOUTHWEST STABILIZING LAKE BREEZES WERE COMMON.

SPRING`S (MARCH-APRIL-MAY) TEMPERATURES AVERAGED BELOW NORMAL...WITH
A COOL MARCH SENDING THE SPRING A FEW DEGREES BELOW NORMAL. IN THE
PRECIPITATION DEPARTMENT A WET APRIL CONTRIBUTED TO AN ABOVE NORMAL
PRECIPITATION SPRING.
