...A WARM DRY JULY FOR WESTERN AND NORTH CENTRAL NEW YORK...

JULY STARTED OUT MOSTLY DRY WITH SOME SHOWERS ACROSS WESTERN AND
NORTH CENTRAL NEW YORK. TEMPERATURES FOR MOST OF THE FIRST WEEK OF
JULY WERE WELL ABOVE NORMAL AS A WARM AND HUMID AIR MASS WAS IN
PLACE ACROSS THE REGION. A COLD FRONT CROSSED THE AREA EARLY ON THE
7TH BRINGING COOLER AND LESS HUMID AIR TO THE REGION FOR THE
FOLLOWING FEW DAYS. ANOTHER ROUND OF INCREASING HEAT AND HUMIDITY
BEGAN ON THE 10TH, STARTING A WARMER THAN NORMAL TREND FOR ALL BUT A
FEW DAYS FOR THE REMAINDER OF THE MONTH. THIS WARM UP ALSO RESULTED
IN THE FIRST 90 DEGREE TEMPERATURE FOR BUFFALO THIS SUMMER. THE
REMNANTS OF POST TROPICAL CYCLONE BARRY MOVED ALONG THE OHIO VALLEY
AND PENNSYLVANIA CAUSING A SURGE OF MOISTURE TO TRACK NORTH INTO
WESTERN AND NORTH CENTRAL NEW YORK AS A WEAK COLD FRONT MOVED SOUTH
OUT OF CANADA. WARM AND HUMID CONDITIONS RETURNED FOR A FEW DAYS
STARTING ON THE 18TH, BRINGING FLORIDA LIKE HUMIDITY TO THE AREA.
HEAT ADVISORIES AND EXCESSIVE HEAT WARNINGS WERE IN EFFECT FOR THE
AREA WITH THE WARMEST HEAT INDEX VALUES EXCEEDING 105 DEGREES. ALSO
DURING THIS WARM AND HUMID STRETCH, AREAS OF THUNDERSTORMS PROMPTED
SEVERE THUNDERSTORM WARNINGS FROM THE NIAGARA FRONTIER TO THE
ROCHESTER AREA.

PRECIPITATION FOR THE MONTH IS BELOW NORMAL IN MOST AREAS, WITH
BUFFALO HAVING WELL BELOW NORMAL RAINFALL AMOUNTS FOR THE MONTH. FOR
THE MONTH OF JULY, BUFFALO RECEIVED 1.83 INCHES OF RAIN WHICH IS
1.40 INCHES BELOW NORMAL OF 3.23 INCHES. FOR BOTH BUFFALO AND
ROCHESTER A MAJORITY OF THE RAINFALL RECEIVED FOR THE MONTH CAME
FROM A FEW DIFFERENT DAYS OF PERSISTENT OR HEAVY RAIN THAT QUICKLY
ADDED UP RAINFALL AMOUNTS. AN APPROACHING AREA OF LOW PRESSURE AND
COLD FRONT CROSSED THE REGION ON THE 5TH AND 6TH, AND BUFFALO
RECEIVED ITS GREATEST DAILY RAINFALL OF 0.60" FOR THE MONTH AND
CONTRIBUTED ALMOST A THIRD OF THE RAIN RECEIVED FOR THE MONTH. THE
NEXT RAINFALL EVENT FOR BUFFALO AND ROCHESTER WAS ON JULY 17TH, WHEN
THE REMNANTS OF POST TROPICAL CYCLONE BARRY MOVED SOUTH OF THE
REGION. BUFFALO RECEIVED 0.35" OF RAIN. FROM JULY 18TH ONWARD THE
AREA EXPERIENCED A FEW DAYS WITH RAIN, MOST OF WHICH WERE ASSOCIATED
WITH SCATTERED SHOWERS AND THUNDERSTORMS. SOME OF THESE SHOWERS AND
THUNDERSTORMS OCCASIONALLY PRODUCED SOME HEAVIER RAINFALL AMOUNTS
THAT FELL QUICKLY BEFORE ENDING. DURING THIS TWO WEEK STRETCH,
BUFFALO RECEIVED 0.86" OF RAIN; WITH 0.73" OF THAT FALLING ON THE
29TH AND 30TH WHEN SHOWERS AND THUNDERSTORMS PRODUCED HEAVY RAIN AT
TIMES OVER THE BUFFALO AIRPORT. IN TOTAL, THE BUFFALO AIRPORT HAD 8
DAYS THAT RECEIVED MEASURABLE RAINFALL.

TEMPERATURES FOR THE MONTH OF JULY FOR MOST OF THE AREA WERE ABOVE
NORMAL BY TWO TO FOUR DEGREES. BELOW AVERAGE TEMPERATURES WERE
EXPERIENCED SEVEN DAYS DURING THE MONTH IN BUFFALO, ALL REMAINING
DAYS WERE EITHER AT OR ABOVE THE NORMAL DAILY TEMPERATURE. THE
AVERAGE TEMPERATURE IN BUFFALO WAS 74.0 DEGREES FAHRENHEIT, WHICH IS
2.9 DEGREES FAHRENHEIT ABOVE THE NORMAL OF 71.1. A WARM HUMID
AIRMASS OVER THE AREA FROM JULY 3RD THROUGH THE 5TH CAUSED HEAT
ADVISORY CONDITIONS (HEAT INDEX OF 95F TO 104F) ACROSS PORTIONS OF
THE AREA FROM THE NIAGARA FRONTIER TO THE GENESEE VALLEY. ANOTHER
STRETCH OF HOT AND HUMID TEMPERATURES PROMPTED HEAT ADVISORIES AND
EXCESSIVE HEAT WARNINGS (HEAT INDEX OF 105F OR GREATER) FOR THE
ENTIRE BUFFALO FORECAST AREA. BUFFALO HIT 90 DEGREES FAHRENHEIT ON
JULY 10TH, FOR THE FIRST TIME THIS SUMMER. SOME OTHER STATISTICS
INCLUDE 24 DAYS THAT HAD HIGH TEMPERATURES GREATER THAN OR EQUAL TO
80 DEGREES FAHRENHEIT, AND THERE WAS 10 DAYS WITH LOW TEMPERATURES
THAT WERE GREATER THAN OR EQUAL TO 70 DEGREES.

IN SUMMARY, A WARMER AND DRIER THAN NORMAL JULY WAS EXPERIENCED FOR
MOST OF WESTERN AND NORTH CENTRAL NEW YORK.
