...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 57.7F DEGREES WAS ABOUT A DEGREE WARMER
THAN NORMAL. THIS WAS OUR FIRST ABOVE NORMAL TEMPERATURE MONTH SINCE
OCTOBER OF 2013. THE MONTH FEATURED 3 DAYS OF 80F OR GREATER...WHICH
IS ONE MORE THAN NORMAL. OF THESE THREE VERY WARM DAYS...TWO TIED
DAILY RECORDS. THE 82F READING ON MAY 9TH AND THE 85F READING ON MAY
13TH TIED THEIR RESPECTIVE DAILY MAXIMUM READINGS.

PRECIPITATION FOR MAY WAS 3.12 INCHES...WHICH IS ABOUT A THIRD OF
AN INCH BELOW NORMAL. MOST OF THE RAIN FELL IN A 4 DAY STRETCH FROM
THE 13TH TO 16TH...TOTALING 2.23 INCHES. THERE WERE NO PRECIPITATION
RECORDS OR EXTREMES THIS MONTH.

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 FLOODING RAINS ACROSS THE SOUTHERN TIER...WITH RAINFALL MORE
MANAGEABLE IN THE BUFFALO METRO AREA. BEHIND THIS WARM FRONT CLOUDS
CLEARED THROUGH THE AFTERNOON AND TEMPERATURES SOARED TO 85F WHICH
TIED A DAILY RECORD HIGH. IT REMAINED MILD OVERNIGHT AND WAS AGAIN
WARM AND HUMID ON THE 14TH AND 15TH WITH 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. THE LAKE LOST ITS ICE IN THE
BUFFALO HARBOR ON MAY 3RD...ITS LATEST ICE OUT DATE SINCE 1996.
DESPITE THE COLD WINTER AND COOL START TO THE SPRING THE LAKE DID
WARM TO 56F BY MONTHS END WHICH IS 2 DEGREES ABOVE NORMAL. WINDS
WERE MODERATE DURING THE MONTH AND SOUTHWEST STABILIZING LAKE
BREEZES WERE COMMON.

SPRING`S (MARCH-APRIL-MAY) TEMPERATURE AVERAGED BELOW NORMAL...WITH
A COOL MARCH SENDING THE SPRING A FEW DEGREES BELOW NORMAL. IN THE
