...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.
RAINFALL WAS EVENLY SPREAD OUT THROUGH THE MONTH.

THE AVERAGE TEMPERATURE OF 67.7F WAS A DEGREE AND A HALF ABOVE
NORMAL. THE NUMBER OF DAYS THAT REACHED 70F WAS ONE BELOW THE NORMAL
OF 24, AND THE NUMBER OF DAYS THAT REACHED 80F WAS ONE ABOVE THE
NORMAL OF 12. THERE WERE NO EXTREMES OR RECORDS SET THIS MONTH. WARM
NIGHTS WERE GREATER THAN NORMAL THIS MONTH, WITH 3 CALENDAR DAYS
REMAINING 70F OR GREATER. THIS IS THE 7TH GREATEST JUNE TOTAL IN
RECORDED HISTORY.

PRECIPITATION WAS CLOSE TO NORMAL THIS MONTH WITH 3.54 INCHES
RECORDED. THIS IS THE 7TH CONSECUTIVE MONTH WITH ABOVE NORMAL
PRECIPITATION FOR ROCHESTER. THE WETTEST DAY THIS MONTH WAS THE 15TH
WHEN WIDESPREAD ONE AND A HALF TO TWO INCHES OF RAIN FELL TO THE
SOUTH AND EAST OF ROCHESTER. AT THE AIRPORT 0.88" OF RAIN WAS
RECORDED. THERE WERE 9 DAYS WITH THUNDERSTORMS THIS MONTH, ABOUT 4
DAYS GREATER THAN NORMAL.

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 ACCOMPANIED THIS WARMTH, WITH WIDESPREAD SEVERE
ACTIVITY ON THE 15TH AND 18TH. 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 0.6 MPH ABOVE THE NORMAL OF 8.0 MPH.

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