...CHANGEABLE TEMPERATURES IN JULY...

THE MONTHLY AVERAGE TEMPERATURE FOR JULY ENDED UP 1.4 DEGREES ABOVE
AVERAGE...BUT THE MONTHLY AVERAGE DOES NOT TELL THE STORY OF THE
CHARACTER OF THE MONTH. JULY 2013 CAN BE BROKEN UP INTO THREE
DISTINCT TEMPERATURE REGIMES. THE FIRST TWO WEEKS OF THE MONTH WERE
ABOVE AVERAGE MOST OF THE TIME BUT NOT EXCESSIVELY SO. THERE WERE
ALSO A FEW SHORT STRETCHES OF BELOW AVERAGE TEMPERATURES FOR THE
FIRST TWO DAYS OF THE MONTH AND A TWO DAY STRETCH ON THE 11TH AND
12TH TO BREAK UP THE WARMTH.

A STRONG RIDGE OF HIGH PRESSURE THEN BUILT OVER MUCH OF THE
NORTHEAST AND GREAT LAKES REGION AND BROUGHT A 6 DAY LONG STRETCH OF
HOT AND VERY HUMID WEATHER DURING THE MIDDLE OF THE MONTH. NO RECORD
HIGHS WERE BROKEN...BUT BOTH THE 17TH AND 18TH SET NEW RECORD WARM
LOW TEMPERATURES OF 77 DEGREES ON BOTH DAYS. HUMIDITY DURING THE
PERIOD WAS EXCESSIVE...WHICH PRODUCED HEAT INDEX VALUES OF OVER 100
DEGREES INLAND FROM THE LAKE ON SEVERAL DAYS. THE HIGH TEMPERATURE
REACHED INTO THE 90S ON 3 DAYS WHICH IS ABOVE THE AVERAGE OF ONE IN
JULY. BUFFALO ONLY AVERAGES THREE 90 DEGREE DAYS PER YEAR. MORE
AMAZINGLY...THE LOW TEMPERATURE DID NOT DROP BELOW 70 DEGREES ON 9
DAYS...WELL ABOVE THE AVERAGE OF 4 DAYS IN JULY AND EVEN ABOVE THE
YEARLY AVERAGE OF 8 DAYS.

A STRONG COLD FRONT MOVED THROUGH THE REGION DURING THE EVENING OF
THE 19TH AND USHERED IN BELOW AVERAGE TEMPERATURES THAT LASTED
THROUGH THE REST OF THE MONTH. FOR MOST THIS BROUGHT A WELCOMED
REPRIEVE FROM HEAT AND HUMIDITY.

PRECIPITATION TOTALED 2.86 INCHES FOR THE MONTH WHICH IS 0.37
INCHES BELOW AVERAGE...BUT AGAIN THE MONTHLY TOTAL DOES NOT TELL THE
STORY. THERE WERE 14 DAYS WITH MEASURABLE RAINFALL WHICH IS WELL
ABOVE THE AVERAGE OF 10 DAYS. THE ONLY LONG DRY STRETCH OCCURRED
DURING AND JUST PRIOR TO THE PERIOD OF HOT WEATHER. THE WETTEST DAY
OF THE MONTH WAS ON THE 19TH WHEN 1.46 INCHES OF RAIN WAS RECORDED
AS A STRONG COLD FRONT CROSSED THE REGION WITH VIVID THUNDERSTORMS
THAT ENDED THE STRETCH OF HOT WEATHER. THESE THUNDERSTORMS PRODUCED
SOME SEVERE WEATHER ACROSS WESTERN NEW YORK WITH SPOTTY WIND DAMAGE
AND SIGNIFICANT FLASH FLOODING ACROSS SOUTHERN NIAGARA COUNTY WHERE
OVER 4 INCHES OF RAIN WAS RECORDED.

SUNSHINE WAS VERY CLOSE TO AVERAGE WITH 66 PERCENT OF POSSIBLE
SUNSHINE...JUST 1 PERCENT SHY OF THE AVERAGE. LAKE ERIE STARTED THE
MONTH A FEW DEGREES ABOVE AVERAGE...BUT THEN SKYROCKETED INTO THE
UPPER 70S DURING THE STRETCH OF HOT WEATHER IN THE MIDDLE OF THE
MONTH. THE LAKE RECORDED DAILY RECORD HIGH TEMPERATURES ON 5 DAYS IN
A ROW FROM THE 17TH THROUGH THE 21ST. THE LAKE REACHED A MAXIMUM OF
78 DEGREES ON THE 19TH AND 20TH...THE EARLIEST IT HAS REACHED 78
SINCE RECORDS BEGAN IN 1927. THE PREVIOUS EARLIEST 78 DEGREE READING
WAS ON JULY 23RD 1987. THE BELOW AVERAGE TEMPERATURES AND ESPECIALLY
THE COOL NIGHTS TOWARDS THE END OF THE MONTH BROUGHT THE LAKE BACK
TO THE AVERAGE OF 73 DEGREES BY THE 31ST.
