... DRY JUNE WITH BOUTS OF SMOKE ...

THERE WERE TWO DISTINCT STRETCHES OF UNSETTLED WEATHER IN AN
OTHERWISE DRY MONTH OF JUNE. AFTER A VERY WARM START TO THE MONTH,
MOST OF THE DAYS WERE COMFORTABLE AND NOT UNTIL THE LAST WEEK DID
HUMIDITY LEVELS BECOME UNCOMFORTABLE. BOTH THE BEGINNING AND END OF
THE MONTH FEATURED THICK WILDFIRE SMOKE WITH UNHEALTHY AIR QUALITY
AND REDUCED VISIBILITY. LAWNS WITH A TINT OF BROWN TO START THE
MONTH RETURNED TO GREEN LUSHNESS BY MONTH`S END WITH AN INCREASE IN
CLOUDS AND WET WEATHER. 

THE TEMPERATURE AVERAGED BELOW NORMAL FOR THE MONTH, AT 65.8 DEGREES
FAHRENHEIT. THE FIRST TWO DAYS OF THE MONTH WERE ALSO THE WARMEST AT
87F AND 89F RESPECTIVELY.  AFTER THE FIRST TWO DAYS IN JUNE, THE 3RD
THROUGH THE 19TH FEATURED BELOW NORMAL TEMPERATURES. THERE WERE JUST
6 DAYS THIS MONTH THAT REACHED INTO THE 80S, FEWEST SINCE 2009 WHICH
FEATURED JUST 2 DAYS IN THE 80S FOR THE MONTH OF JUNE.   

PRECIPITATION TOTALED 2.55 INCHES AND WAS ABOUT THREE-QUARTERS OF AN
INCH BELOW NORMAL. THERE WERE TWO DISTINCT PERIODS OF UNSETTLED
WEATHER, BOTH WITH SLOW MOVING UPPER LEVEL LOW PRESSURE SYSTEMS
MOVING THROUGH THAT BROUGHT AN EXTENDED PERIOD OF CLOUDS AS WELL AS
SOAKING RAINFALLS. THE 12TH THROUGH THE 16TH FEATURED AN INCH AND A
HALF OF PRECIPITATION, AND THE 24TH THROUGH THE 28TH FEATURED NEARLY
AN INCH OF PRECIPITATION. OTHERWISE ALL BUT ONE DAY FEATURED NO
MEASURABLE PRECIPITATION.  

JUNE STARTED VERY WARM AND DRY WITH A RIDGE OF HIGH PRESSURE
OVERHEAD. DRY LAWNS FROM MAY SHOWED SIGNS OF BECOMING PARCHED IN THE
EARLY JUNE HEAT. A WEAK COLD FRONT DROPPED ACROSS WESTERN NEW YORK
EARLY ON THE 3RD, AND BROUGHT RELIEF FROM THE HEAT THOUGH NO RELIEF
IN THE PRECIPITATION CATEGORY.  COMFORTABLE CONDITIONS ON THE 3RD
AND 4TH WERE DIMMED BY THE ARRIVAL OF ANOTHER PLUME OF WILDFIRE
SMOKE. A SPECTACULAR RED SUNSET ON THE 5TH WITH WILDFIRE SMOKE
AROUND. BY THE 9TH WINDS BEGAN TO SHIFT TO THE SOUTHWEST, DRIVING
THE SMOKE OUT OF THE REGION. THE 10TH RECORDED JUST A FEW HUNDREDTHS
OF AN INCH OF RAINFALL. THE PARCHED GROUNDS FINALLY RECEIVED RELIEF
ON THE 12TH AS A SLOW MOVING UPPER LEVEL LOW MOVED OVER THE GREAT
LAKES. THIS SYSTEM BROUGHT THE FIRST OF TWO EXTENDED PERIODS OF
CLOUDY AND WET WEATHER, WITH A SOAKING RAIN ON SUNDAY THE 12TH WELL
RECEIVED BY AGRICULTURAL INTERESTS. LAWNS QUICKLY RETURNED BACK TO
GREEN. THE 15TH THROUGH THE 23RD WAS MARKED BY AN EXTENDED PERIOD OF
MAINLY DRY CONDITIONS, AND DAY TO DAY WARMING TEMPERATURES. ONLY THE
16TH FEATURED RAIN SHOWERS. ANOTHER CLOSED LOW FROM THE SOUTHEAST
BROUGHT BACK A PERIOD OF UNSETTLED CONDITIONS AS WELL AS THE FIRST
PROLONGED PERIOD OF UNCOMFORTABLE HUMIDITY LEVELS. DOWNPOURS ON THE
24TH WERE THE FIRST OF 5 DAYS OF SHOWERS AND THUNDERSTORMS IN THE
GENESEE VALLEY. THOUGH VEGETATION BECAME GREEN, DEEP MOISTURE WAS
STILL LACKING IN THE GROUND AND MODERATE DROUGHT CONDITIONS
PREVAILED THROUGH THE END OF THE MONTH. OVERNIGHT LOWS IN THE 60S
COMBINED WITH THE HIGHER LEVEL OF HUMIDITY LEFT THE NIGHTS MUGGY.
THE 26TH BECAME ACTIVE WITH SEVERAL THUNDERSTORMS BECOMING SEVERE
WITH HAIL AND DAMAGING WIND GUSTS. MUCH OF THE DAMAGE WAS NEAR THE
SHORELINES OF LAKE ERIE, AND ONTARIO AS WELL AS NEAR GENEVA NY.
THICK SMOKE AGAIN RETURNED TO WESTERN NEW YORK ON THE 28TH AND 29TH,
AND THERE WAS AT LEAST SOME OBSTRUCTION TO THE VISIBILITY THROUGH
THE END OF THE MONTH. THE FINAL DAY FEATURED WARM CONDITIONS WITH
SCATTERED THUNDERSTORMS ACROSS WESTERN NEW YORK. 

THE WATER TEMPERATURE ON LAKE ONTARIO WARMED FROM THE UPPER 40S AT
THE BEGINNING OF JUNE TO THE MID 60S BY THE END OF JUNE. THE WINDS
WERE A BIT BELOW NORMAL, WITH AN AVERAGE SPEED OF 7.4 MILES PER HOUR
LOWER THAN THE NORMAL BY SIX-TENTHS OF A MILE PER HOUR. THE
STRONGEST WIND GUST OCCURRED ON THE 3RD FOLLOWING THE PASSAGE OF A
COLD FRONT. 

IN ALL A DRY, SMOKEY MONTH WITH TWO DISTINCT PERIODS OF UNSETTLED
WEATHER.
