... WARM AND HUMID JUNE ...
AFTER A PLEASANT MAY, THE HEAT AND HUMIDITY WERE TURNED ON FOR JUNE,
ESPECIALLY THE FINAL HALF OF THE MONTH WHERE DAYTIME HIGHS ROUTINELY
RAN IN THE 80S AND SEVERAL NIGHTS REMAINED UNCOMFORTABLE IN THE 70S.
A SOUTHWEST LAKE BREEZE DID OFFER SOME RELIEF DURING THE AFTERNOON
HOURS. THERE WERE SEVERAL ROUNDS OF THUNDERSTORMS THIS MONTH,
HOWEVER, THE OVERALL PRECIPITATION AVERAGED YET AGAIN BELOW NORMAL.
THE TEMPERATURE AVERAGED 69.2F THIS MONTH WHICH IS THE 9TH WARMEST
JUNE ON RECORD. THIS TEMPERATURE AVERAGE WAS ABOUT TWO AND A HALF
DEGREES ABOVE NORMAL. OVERNIGHT LOW TEMPERATURES HAD A LARGE
POSITIVE TEMPERATURE DEPARTURE. THE 5 DAYS REMAINING 70F OR WARMER
IS TIED FOR 5TH GREATEST ON RECORD. THE 59F DEGREE READING ON THE
1ST WAS THE FIRST MAXIMUM TEMPERATURE IN THE 50S FOR JUNE SINCE
2019. THE HIGHLIGHT OF THIS WARM MONTH WAS THE 22ND THROUGH THE 25TH
WHEN DAILY MEAN TEMPERATURES WERE ABOUT 10 DEGREES ABOVE NORMAL.
WITHIN THIS STRETCH OCCURRED TWO RECORD WARM MINIMUM TEMPERATURES,
WITH THESE BEING BOTH 73F ON THE 23RD AND 24TH.
PRECIPITATION FOR THE MONTH TOTALED 3.35 INCHES WHICH IS JUST TWO-
HUNDREDTHS OF AN INCH BELOW THE MONTHLY NORMAL. THIS IS NOW THE 11TH
MONTH OF THE PAST 12 MONTHS TO FEATURE BELOW NORMAL PRECIPITATION.
THE PRECIPITATION THIS MONTH WAS MAINLY DRIVEN BY CONVECTION. OF THE
9 WEEKEND DAYS THIS MONTH ONLY SUNDAY THE 15TH AND SUNDAY THE 29TH
REMAINED RAIN-FREE. THE 10 DAYS WITH MEASURABLE PRECIPITATION IS 1
DAY FEWER THAN NORMAL.
THE MONTH BEGAN ON THE CHILLY SIDE WITH A DEEP UPPER LEVEL TROUGH OF
LOW PRESSURE OVERHEAD. THE COOL PATTERN WAS SHORT-LIVED AS A WARM
AND DEEP MOISTURE AIRMASS PUSHED INTO WESTERN NEW YORK ON THE 5TH,
PRODUCING LARGE HAIL AND FLASH FLOODING ACROSS THE WESTERN SOUTHERN
TIER. ON THE 9TH ANOTHER WARM FRONT LIFTED INTO WESTERN PORTIONS OF
NEW YORK STATE; AND THUNDERSTORMS BECAME ABUNDANT UPON THIS FRONT,
BOTH NEAR LAKE ONTARIO AND ALSO WESTERN NEW YORK. ONE OF THESE
THUNDERSTORMS SPAWNED AN EF-1 TORNADO THAT TORE THROUGH THE TOWN OF
GREAT VALLEY, NEW YORK DAMAGING SEVERAL STRUCTURES AS WELL AS
BRINGING HARDWOOD TREES DOWN. ON THE 18TH A COLD FRONT STALLED TO
THE WEST OF NEW YORK STATE, WITH A PLUME OF DEEP TROPICAL MOISTURE
STREAMING ACROSS WESTERN NEW YORK. THIS AIRMASS FUELED SEVERAL
CLUSTERS OF DRENCHING THUNDERSTORMS, OF WHICH SOME PRODUCED FLASH
FLOODING ACROSS PARTS OF FAR SOUTHERN ERIE COUNTY EASTWARD INTO THE
GENESEE VALLEY AND FINGER LAKES REGION WHERE MOST OF THE FLOODING
OCCURRED ON THE 18TH. WARM AND STICKY CONDITIONS REMAINED ACROSS
WESTERN NEW YORK THE REMAINDER OF THE MONTH. IN FACT, FOR THE ENTIRE
MONTH OF JUNE THE DEWPOINT AVERAGED 59.7F WHICH IS THE HIGHEST
AVERAGE IN THE PAST 20 YEARS AT THE AIRPORT. FROM THE 22ND THROUGH
THE 25TH THE TEMPERATURES NEVER DROPPED BELOW 70. THIS IS JUST THE
THIRD 4-DAY STRETCH OF CONSECUTIVE 70 DEGREE OR WARMER TEMPERATURES
IN THE MONTH OF JUNE, WITH THE OTHER TWO OCCURRING IN JUNE 2021 AND
JUNE OF 2024. ON THE 27TH THUNDERSTORMS STALLED AND EXPANDED ACROSS
LIVINGSTON COUNTY, BRINGING FLASH FLOODING TO GENESEO, YORK AND
LAKEVILLE AREAS. OVER 5 INCHES OF RAIN SWELLED SMALL CREEKS INTO
RAGING RIVERS, FLOODED MANY ROADS AND BASEMENTS AND INUNDATED A
SCHOOL. NUMEROUS SHOWERS AND THUNDERSTORMS THE FINAL DAY OF THE
MONTH BROUGHT THE MONTH`S GREATEST RAINFALL TO THE BUFFALO AIRPORT,
BUT NOT QUITE ENOUGH RAINFALL TO PUSH THE MONTHLY PRECIPITATION TO
ABOVE NORMAL.
LAKE ERIE WATER TEMPERATURE ROSE FROM 55F TO 70F THROUGH THE
MONTH, WITH THIS 70F READING 3 DEGREES HIGHER THAN NORMAL. WINDS
WERE A BIT ABOVE NORMAL THIS MONTH, FINISHING ABOUT A HALF A MILE
PER HOUR ABOVE NORMAL. THE STRONGEST WIND GUST WAS 47 MPH ON THE
19TH, WITH THIS SOUTHWEST GUST OCCURRING AS A DEEPENING AREA OF LOW
PRESSURE PASSED JUST TO THE WEST AND NORTH OF NEW YORK STATE.
IN ALL, A HUMID SUMMER MONTH.
