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. && THOMAS $$
