...A WET JUNE LACKING ANY PROLONGED HEAT...

ON THE HEELS OF A SOAKING END TO MAY...THE MONTH OF JUNE CONTINUED
THE ROUNDS OF SHOWERS AND THUNDERSTORMS. OVER HALF THE DAYS
CONTAINED MEASURABLE RAINFALL...AND THIS RAINFALL WAS SPREAD EVENLY
THROUGHOUT THE MONTH. THE MAJORITY OF WESTERN NEW YORK FINISHED AN
INCH OR MORE ABOVE NORMAL JUNE PRECIPITATION. ALONG WITH THIS
RAIN...DAYS WERE CLOUDIER THAN NORMAL AND AIR TEMPERATURES FINISHED
THE MONTH SLIGHTLY BELOW NORMAL.

THE AVERAGE TEMPERATURE FOR JUNE FINISHED AT 65.6F DEGREES WHICH IS
0.7 DEGREES BELOW NORMAL. THE WARMEST TEMPERATURE IN JUNE WAS A MERE
84F DEGREES ON THE 12TH. THERE WERE ONLY FIVE DAYS THAT REACHED THE
80S...AND THIS TOTAL WAS THE 7TH FEWEST AMOUNT OF DAYS SINCE
OBSERVING RECORDS MOVED TO THE AIRPORT IN 1943. ON THE 28TH THE
TEMPERATURE REACHED A HIGH OF ONLY 61F...WHICH WAS THE COOLEST
MAXIMUM TEMPERATURE FOR THE DATE...BREAKING A RECORD OF 63F SET BACK
IN 2004.

PRECIPITATION TOPPED FIVE INCHES FOR THE 18TH JUNE IN RECORDED
HISTORY (RECORDS START 1871). THE 5.03 INCHES WAS AN INCH AND A
THIRD ABOVE NORMAL AND CAME ON 16 DAYS OF MEASURABLE PRECIPITATION.
OF THE PAST SIX JUNES...THREE HAVE HAD OVER FIVE INCHES OF RAINFALL.
THERE WAS ONE RECORD RAINFALL EVENT...WITH THE 1.72 INCHES ON THE
27TH BREAKING THE OLD RECORD OF 1.29 INCHES SET BACK IN 2006. THERE
WERE FOUR DAYS THAT RECEIVED A HALF AN INCH OR MORE OF
RAINFALL...TWICE THE TYPICAL AMOUNT OF TWO DAYS. EVERY SUNDAY THIS
MONTH RECORDED MEASURABLE RAINFALL.

THE RECORD SOAKING RAINFALL OF LATE MAY...THAT ENDED IN THE WEE
HOURS OF JUNE WAS JUST A SIGN OF THE PATTERN FOR THE MONTH OF JUNE.
A MEAN LONGWAVE TROUGH REMAINED OVER THE GREAT LAKES REGION THIS
MONTH...A TROUGH THAT FAVORED STORM DEVELOPMENT OVER THE EASTERN
GREAT LAKES REGION. SEVERAL STORM SYSTEMS PRODUCED MODERATE TO HEAVY
RAINFALL THROUGH THE MONTH. THE FIRST SIGNIFICANT STORM SYSTEM CAME
THROUGH WESTERN NEW YORK ON THE 8TH AND 9TH OF THE MONTH...SPREADING
A HALF TO ONE INCH OF RAINFALL...AND ALSO GUSTY THUNDERSTORM WINDS
ON THE MORNING OF THE 9TH. MORE WIDESPREAD SEVERE THUNDERSTORMS
DROPPED ACROSS THE REGION ON THE 11TH...WITH BOTH THE HEAVIER
RAINFALL AND DAMAGE FOUND EAST OF BUFFALO ACROSS THE GENESEE VALLEY
AND FINGER LAKES REGION. A BRIEF TORNADO SPUN UP JUST NORTH OF
CANANDAIGUA DURING THE LATE EVENING HOURS OF THE 11TH. THE NEXT
SYSTEM OF NOTE CAME SEVERAL DAYS LATER WHEN ANOTHER WARM FRONT AND
HUMID AIRMASS EDGED INTO WESTERN NEW YORK THROUGH THE EARLY MORNING
HOURS OF SUNDAY THE 14TH. ONE SLOW MOVING THUNDERSTORM PRODUCE FLASH
FLOODING ACROSS WARSAW IN WYOMING COUNTY LATE SUNDAY AFTERNOON.
ADDITIONAL SHOWERS AND DRENCHING THUNDERSTORMS PASSED ACROSS WESTERN
NEW YORK LATER SUNDAY NIGHT. ANOTHER COLD FRONT CROSSED THE REGION
ON THE 23RD WITH EARLY MORNING HEAVY RAIN SHOWERS AND A FEW SEVERE
THUNDERSTORMS DOWNING TREES ACROSS WESTERN NEW YORK. LASTLY ANOTHER
SYNOPTIC STORM SYSTEM ROSE NORTHWARD FROM THE SOUTH WITH A LENGTHY
PERIOD OF HEAVY RAIN SHOWERS ON THE 27TH-28TH. THIS WEEKEND SOAKING
RAINFALL BROUGHT SEVERAL INCHES OF RAIN TO WESTERN NEW YORK AND
RUINED MANY OUTDOOR PLANS.

LAKE ERIE`S WATER TEMPERATURE RANGED FROM 55F DEGREES AT MONTH`S
BEGINNING TO 65F DEGREES ON THE 26TH. WIND SPEED AVERAGED 9.2 MPH
WHICH IS NEAR THE NORMAL OF 9.3 MPH.

IN ALL A COOL...AND VERY WET START TO SUMMER.
