...A WET JUNE...

THE MONTH OF JUNE FEATURED ABUNDANT RAINFALL AND MODEST HUMIDITY
ACROSS THE NORTHEAST. RAINFALL WAS SPREAD THROUGHOUT THE MONTH AND
THE NUMBER OF THUNDERSTORMS WERE NEAR NORMAL. A COMMON THEME THIS
MONTH WAS SLOW MOVING THUNDERSTORMS...WHICH WHEN COMBINED WITH THE
HEAVY RAINFALL BROUGHT FLOODING TO THE REGION...AND LOCALIZED FLASH
FLOODING.

MORE THAN HALF THE DAYS (16) THIS MONTH FEATURED RAINFALL...OF WHICH
THERE WAS A JUNE RECORD TYING 6 DAYS WITH A HALF INCH OR GREATER
TOTAL. THIS RAINFALL BROUGHT JUNE`S PRECIPITATION UP TO 7.16 INCHES
WHICH PLACES 6TH WETTEST FOR THE MONTH. RAINFALLS WERE FROM BOTH
SYNOPTIC LOWS PASSING NEAR THE REGION AND CONVECTIVE COMPLEXES
PASSING ACROSS THE REGION. FOR THE BUFFALO METRO AREA THE MAIN
IMPACT FROM THESE THUNDERSTORMS WAS THE HEAVY RAINFALL. DESPITE THE
HEAVY RAINS NO EXTREME DAILY RAINFALLS OCCURRED.

JUNE`S TEMPERATURES RAN CLOSE TO NORMAL THROUGH THE MONTH WITH ONLY
THREE DAYS WITH A 10 DEGREE OR GREATER SPREAD FROM THE NORMAL.
MAXIMUM TEMPERATURES FOR THE MONTH FINISHED ABOUT 2 DEGREES BELOW
THE NORMAL...WHILE OVERNIGHT MINIMUMS WERE ABOUT A DEGREE ABOVE
NORMAL. THIS BROUGHT JUNES FINAL MEAN TEMPERATURE TO 65.7...WHICH IS
ABOUT A HALF A DEGREE BELOW NORMAL. THERE WAS ONE RECORD WARM
MINIMUM...ON THE 24TH THE LOWEST TEMPERATURE RECORDED WAS 72F WHICH
BROKE THE OLD RECORD OF 70F SET BACK IN 1923.

JUNE STARTED VERY WARM AND MOIST AHEAD OF A SLOW MOVING COLD FRONT
FROM THE CENTRAL GREAT LAKES. MORNING SUNSHINE ON THE 1ST
DESTABILIZED THE ATMOSPHERE SUCH THAT TORRENTIAL RAINFALLS WITHIN
THUNDERSTORMS CROSSED THE BUFFALO METRO AREA LATE ON THE 1ST AND
INTO THE EARLY MORNING HOURS OF THE 2ND. THIS RAINFALL BROUGHT A
RISE TO LOCAL CREEKS AND STREAMS...THOUGH MANY STAYED WITHIN THEIR
BANKS. A DRY AND QUIET STRETCH FOLLOWED...AND THE 58F DEGREE READING
ON 3RD WAS THE FIRST SUB 60F MAXIMUM IN THE MONTH OF JUNE SINCE 2003. A
LOW MOVING OUT FROM THE OHIO VALLEY BROUGHT STEADY RAIN ACROSS
WESTERN NEW YORK ON THE 6TH. A MORE CONVECTIVE CLUSTER OF SHOWERS
AND THUNDERSTORMS RODE ALONG A WARM FRONT ON THE 13TH AND THIS
BROUGHT ANOTHER INCH TO TWO INCHES OF RAINFALL TO WESTERN NEW YORK.

AFTER SEVERAL ADDITIONAL DAYS OF LIGHT SHOWERS A BEAUTIFUL STRETCH
ENTAILED ACROSS THE REGION. SPRAWLING HIGH PRESSURE DROPPED
SOUTHWARD FROM CANADA AND ANCHORED ACROSS THE REGION FROM THE 18TH
THROUGH THE 21ST. THIS AIRMASS BROUGHT US COMFORTABLE...LOW HUMIDITY
AFTERNOONS WITH PLENTY OF SUNSHINE TO GIVE US A BREAK FROM THE
UNSETTLED FIRST HALF OF THE MONTH. DAYS OF RAINFALL WOULD SOON
RETURN AS HEAT AND HUMIDITY SLOWLY BUILT WITH THUNDERSTORMS
OCCURRING AGAIN ON THE 22ND AND 23RD. A STALLED AMPLIFIED PATTERN
LATE IN THE MONTH BROUGHT A CONTINUED SOUTHERLY FLOW OF MOISTURE
WITH THIS MOISTURE FUELING SLOW MOVING THUNDERSTORMS THAT BROUGHT
LOCALIZED FLOODING ON THE 27TH AND 28TH.

SUNSHINE FOR THE MONTH WAS BELOW NORMAL WITH ONLY 57 PERCENT OF
POSSIBLE SUN FOR THE MONTH. THIS IS 7 POINTS BELOW NORMAL. THERE
WERE 15 MOSTLY SUNNY DAYS...WHILE 5 DAYS RECORDED NO SUNSHINE AT
ALL. WINDS WERE LIGHTER THAN NORMAL FOR THE MONTH WITH THE 45 MPH
GUST ON THE 2ND THE HIGHEST GUST RECORDED. LAKE ERIE CONTINUED TO
AVERAGE A FEW DEGREES ABOVE NORMAL WITH LAKE WATER TEMPERATURES
RISING TO 69F BY MONTHS END.

IN ALL JUNE FINISHED TO BE A WET MONTH...WITH SEVERAL HEAVY RAINFALL
EVENTS.
