...A MORE TYPICAL JUNE FOR WESTERN NEW YORK...

AFTER THE SECOND WETTEST SPRING ON RECORD, A MORE TYPICAL JUNE
UNFOLDED, WITH A JUNE GLOOM PROVIDING FOR A COOL START TO THE MONTH.
BY MID MONTH SUMMER`S WARMTH WAS UPON US COUPLED WITH SHOWERS AND
THUNDERSTORMS. A MIX OF COOL AND WARM DAYS CLOSED OUT THE MONTH. THE
BULK OF THE RAIN THIS MONTH FELL THE SECOND HALF OF THE MONTH.

THE AVERAGE TEMPERATURE OF 67.3F WAS A DEGREE ABOVE NORMAL. THE
NUMBER OF DAYS THAT REACHED 70F WAS EXACTLY THE NORMAL OF 24, AND
THE NUMBER OF DAYS THAT REACHED 80F WAS 10 (11 NORMAL). THERE WAS
ONE RECORD WARM MINIMUM TEMPERATURE REACHED, AND THIS WAS 70F ON THE
11TH, TYING THE RECORD FROM 1942. WARM NIGHTS WERE GREATER THAN
NORMAL THIS MONTH, WITH 6 CALENDAR DAYS REMAINING 68F OR GREATER.
THIS IS THE 4TH GREATEST JUNE TOTAL SINCE RECORDS MOVED TO THE
AIRPORT IN THE SUMMER OF 1943.

PRECIPITATION WAS WELL BELOW NORMAL THIS MONTH, WITH 2.21 INCHES
MEASURED. THE FIRST TWO WEEKS OF JUNE MEASURED JUST 0.28 INCHES OF
RAIN, WHICH IS THE DRIEST START TO JUNE SINCE 1977. THE WETTEST DAY
THIS MONTH WAS FATHER`S DAY, THE 18TH WHEN A HALF TO ONE INCH OF
RAINFALL FELL ACROSS THE METRO BUFFALO AREA.

THROUGH THE FIRST 9 DAYS OF THE MONTH AN UPPER LEVEL TROUGH OF LOW
PRESSURE DOMINATED THE GREAT LAKES REGION, WITH TEMPERATURES
GENERALLY BELOW NORMAL. HOWEVER PRECIPITATION EVENTS WERE GENERALLY
ON THE LIGHT SIDE WITHIN THIS TROUGH. BY THE 10TH AN UPPER LEVEL
RIDGE FROM THE PLAINS SHIFTED EASTWARD, AND BROUGHT BOTH SUMMER`S
HEAT AND HUMIDITY TO THE EASTERN GREAT LAKES REGION. A FEW SHOWERS
AND THUNDERSTORMS MID-MONTH CULMINATED ON THE 18TH WHEN WIDESPREAD
SEVERE THUNDERSTORMS FORMED OVER WESTERN NEW YORK WITH DAMAGING
WINDS. AN UPPER LEVEL TROUGH OF LOW PRESSURE THEN SETTLED OVER THE
REGION FOR THE FOURTH WEEK OF THE MONTH. COOL TEMPERATURES SETTLED
BACK ACROSS WESTERN NEW YORK, WITH SCATTERED SHOWERS AND
THUNDERSTORMS. AT THE HEIGHT OF THE COLD PERIOD, AFTERNOON
TEMPERATURES WERE IN THE UPPER 60S TO LOWER 70S WITH WATERSPOUTS
FORMING ON BOTH LAKE ERIE AND ONTARIO ON THE 26TH AND 27TH.

SOUTHWEST WINDS WERE PREVALENT THIS MONTH, WITH THE MONTHLY AVERAGE
WINDS SPEEDS 1.4 MPH ABOVE THE NORMAL OF 9.3 MPH. LAKE ERIE
CONTINUED ITS RECORD WARMTH PACE, WARMING FROM 59F AT MONTHS START
TO 73F AT MONTHS END.

IN ALL A FAIRLY TYPICAL MONTH WITH NO PROLONGED EXTREME EVENTS.
