THE INCREDIBLE WARMTH THAT BEGAN WITH AN EL NIO WINTER AND CONTINUED THROUGH THE SPRING MONTHS CARRIED ON INTO THE START OF THE SUMMER, WITH BUFFALO YET AGAIN RECORDING A TOP 10 WARMEST MONTH ON RECORD. THIS JUNE, THE FIFTH CONSECUTIVE TOP 10 WARMEST MONTH ON RECORD, FINISHED 6TH WARMEST IN 154 YEARS OF DATA. SEVERAL ROUNDS OF SUMMER STORMS THROUGH THE MONTH KEPT LAWNS AND VEGETATION GREEN, YET WITHOUT ANY SIGNIFICANT FLOODING. THE TEMPERATURE AVERAGED 70.2F THIS MONTH, WHICH IS JUST OVER THREE DEGREES ABOVE NORMAL. THE MAXIMUM AND MINIMUM TEMPERATURE DEPARTURES WERE ESSENTIALLY THE SAME FOR THE MONTH, AND THE ABOVE NORMAL DAYS OUTWEIGHED THE BELOW NORMAL DAYS BY A TWO TO ONE RATIO. THERE WERE TWO COOL SPELLS THIS MONTH, THE FIRST OF A WEEK MAGNITUDE OCCURRING FROM THE 7TH THROUGH THE 12TH, AND A SHORTER PERIOD 3 OF THE FINAL 4 DAYS OF THE MONTH. BETWEEN THESE COOL SPELLS, A STRETCH OF MID-JULY LIKE HUMIDITY AND HEAT OCCURRED FROM THE 17TH THROUGH THE 22ND. SEVERAL DAYS HAD DEWPOINTS TOP 70F WHICH WITH TEMPERATURES IN THE LOWER 90S CREATED HEAT INDEX VALUES AROUND 100F. THE TEMPERATURE FOR 6 DAYS BETWEEN THE 17TH AND 22ND REMAINED ABOVE 70F, THE LONGEST JUNE STRETCH ON RECORD. THE 15 DAYS OF 80 DEGREES OR WARMER TEMPERATURES ARE FOUR DAYS MORE THAN NORMAL. THERE WERE THREE RECORDS, THE 90F ON THE 19TH TYING WITH 2001 FOR WARMEST EVER FOR THE DATE, AND THE 76F TEMPERATURE ALSO ON THE 19TH BREAKING THE FORMER RECORD WARMEST MINIMUM TEMPERATURE BY 3 DEGREES (1919). THE THIRD RECORD WAS ALSO A RECORD WARMEST MINIMUM TEMPERATURE, WITH THE 74F READING ON THE 22ND TYING WITH 1888. PRECIPITATION FOR THE MONTH TALLIED 4.78 INCHES, WHICH IS ABOUT AN INCH AND A HALF ABOVE NORMAL. THROUGHOUT MUCH OF THE MONTH THE MONTHLY DEPARTURE REMAINED CLOSE TO NORMAL, STRAYING JUST TWO THIRDS OF AN INCH ABOVE NORMAL ON THE 9TH. A RECORD BREAKING 1.66 INCHES OF RAIN ON THE 30TH SENT THE MONTHLY DEPARTURE TO ABOVE AN INCH. THIS 1.66 INCHES OF RAIN ON THE 30TH WAS ALSO THE WETTEST DAY FOR THE MONTH, AND BROKE A LONG STANDING RECORD FROM 1897 (0.84 INCHES). THE 4 DAYS TALLYING MORE THAN HALF AN INCH IS TIED FOR 6TH GREATEST NUMBER OF DAYS IN JUNE RECORDS. HIGH PRESSURE STARTED THE MONTH OF JUNE PLEASANT. AFTER A BEAUTIFUL SUNRISE, A WEAKENING AREA OF LOW PRESSURE BROUGHT RAIN SHOWERS TO WESTERN NEW YORK ON THE 2ND. A TOUCH OF HUMIDITY BUILT INTO THE REGION ON THE 5TH AND 6TH WITH A FEW SHOWERS AND THUNDERSTORMS AROUND. MORE STORMS FORMED ON THE 7TH AHEAD OF A COLD FRONT. THIS FRONT BROUGHT A COOLER AIRMASS ACROSS THE EASTERN GREAT LAKES, ONE THAT WOULD LAST THROUGH THE 12TH. UNDER AN UPPER LEVEL TROUGH RAIN SHOWERS WERE PLENTIFUL DURING THE FIRST HALF OF THIS COOL STRETCH. EVENTUALLY DRIER AIR WON OUT AND THE 12TH THROUGH THE 15TH OF THE MONTH FEATURED FABULOUS EARLY SUMMER WEATHER WITH DAY TO DAY WARMING. THE 17TH THROUGH THE 22ND FEATURED A HOT AND HUMID AIRMASS THAT BROUGHT EARLY SUMMER`S UNCOMFORTABLENESS TO WESTERN NEW YORK. THE 17TH ALSO SAW THUNDERSTORMS BLOSSOM THROUGH THE AFTERNOON AND EVENING HOURS, WITH SOME OF THESE STORMS BECOMING SEVERE, DOWNING TREES AND WIRES ACROSS THE INLAND PORTIONS OF WNY. HEAVY RAIN EARLY ON THE 18TH ACROSS NIAGARA COUNTY AND FAR NORTHERN ERIE COUNTY BROUGHT LOCALIZED THREE INCH AMOUNTS WITH FLASH PONDING OF WATER ON ROADWAYS. THIS ACTIVITY IN A WEAKER STATE ALSO DROPPED PAST THE BUFFALO AIRPORT. THE FIRST 90 DEGREE TEMPERATURE OF THE YEAR OCCURRED ON THE 18TH WHEN A TEMPERATURE OF 93F DEGREES WAS MEASURED AT THE AIRPORT. A FEW STORMS DID FORM ON THE AFTERNOON HOURS OF THE 18TH BRINGING RELIEF FOR SPOTTY LOCATIONS ACROSS WESTERN NEW YORK FROM THE HEAT. A COLD FRONT ON THE 19TH BROUGHT ANOTHER ROUND OF STRONG TO SEVERE THUNDERSTORMS, WITH INLAND AREAS AND THE SOUTHERN TIER RECEIVING THUNDERSTORM WIND DAMAGE. SUNDAY, THE 23RD FEATURED A FEW SHOWERS AND THUNDERSTORMS, BUT ALSO NOTABLE SOUTHWEST WINDS THROUGH THE AFTERNOON AND EARLY EVENING HOURS. IT WOULD NOT BE UNTIL EARLY ON THE 24TH THAT A MUCH STRONGER FRONT WOULD PASS ACROSS WESTERN NEW YORK THAT SWEPT SUMMER`S HEAT AND HUMIDITY EASTWARD. ON THE 29TH A MOISTURE RICH AIRMASS ALONG A WARM FRONT PRODUCED HEAVY SHOWERS AND A FEW THUNDERSTORMS THROUGH THE MORNING HOURS. THE FINAL DAY OF THE MONTH REMAINED MOSTLY CLOUDY AND LESS HUMID WITH A NORTHWEST FLOW. THE WATER TEMPERATURE ON LAKE ERIE REMAINED NEAR OR AT RECORD LEVELS THROUGH THE MONTH. STARTING THE MONTH AT 62F, THE LAKE TEMPERATURE ROSE TO 70F ON THE 19TH, WHICH IS THE EARLIEST 70F READING EVER FOR THE LAKE. BY THE END OF THE MONTH THE WATER TEMPERATURE WOULD REACH 75F. WINDS WERE A TAD BELOW NORMAL FOR THE MONTH, AND THE GREATEST WIND GUST OCCURRED IN SYNOPTIC SOUTHWEST WINDS WITH 53 MPH RECORDED AT THE AIRPORT ON THE 23RD. THIS 53 MPH GUST IS THE 2ND HIGHEST GUST RECORDED IN THE MONTH OF JUNE SINCE 2007. IN ALL ANOTHER MONTH NOTED FOR ITS WARMTH. && THOMAS $$
