...WARM AND DRY...

JULY CONTINUED A SUMMER TREND OF WARM AND DRY CONDITIONS, LEADING
TO A MODERATE DROUGHT SITUATION ACROSS THE LOWER GENESEE VALLEY.
WATER USAGE WAS WAY UP AS GREEN LAWNS TURNED BROWN AND THE AGRICULTURAL
COMMUNITY STRAINED TO KEEP CROPS FROM DRYING UP. IN TERMS OF WEATHER
SYSTEMS, SEVERAL WEAK COLD FRONTS MOVED THROUGH DURING THE FIRST
THREE WEEKS OF THE MONTH WITH LITTLE IMPACT. THESE FRONTS PASSED ON
JULY 4TH, 7TH, 18TH, AND 23RD. A FEW OTHER WEAK FEATURES MOVED
THROUGH AT OTHER TIMES, BUT NONE WERE ABLE TO ALLEVIATE THE
PREVAILING WARM AND DRY CONDITIONS. THERE WERE TWO NOTABLE WEATHER
EVENTS DURING THE LAST WEEK OF THE MONTH, AND BOTH GAVE THE
ROCHESTER AREA SOME TEMPORARY RELIEF FROM THE DROUGHT CONDITIONS.
THE FIRST SYSTEM DROPPED FAIRLY HEAVY RAIN OVER THE REGION ON THE
26TH, AND A COLD FRONT BROUGHT MORE RAIN TO THE AREA ON THE LAST DAY
OF THE MONTH.

THE AVERAGE TEMPERATURE OF 74.5F WAS 3.7 ABOVE NORMAL. THIS MAKES
JULY 2012 THE 10RD WARMEST IN OUR 142 YEAR RECORD. LAST YEAR WAS A
CLOSE 9TH PLACE AT 74.6.F. WE HAVE REACHED THE TOP 20 WARMEST JULY
MONTHS FOUR TIMES SINCE THE NEW MILLENNIUM. ALL BUT 2 DAYS WERE AT
OR ABOVE 80F. LAST YEAR HOWEVER HOLDS THE RECORD WITH 30 DAYS. A 21
DAY STREAK OF 80 OR ABOVE STARTED ON JUNE 28 AND ENDED ON JULY 18.
THIS IS THE 7TH LONGEST STRETCH OF DAYS AT OR ABOVE 80F, ALTHOUGH A
LONGER STRETCH WAS ACHIEVED IN BOTH 2010 AND 2011. THERE WERE 8 DAYS
AT OR ABOVE 90F. THE AVERAGE NUMBERS OF DAYS SINCE RECORDS WERE
REPORTED AT THE AIRPORT AT OR ABOVE 90F ARE 4. THERE WAS ONE RECORD
HIGH FOR THE MONTH. 97F WAS REACHED ON THE 17TH.  THERE WERE NO
RECORD LOWS.

RAINFALL TOTALED 2.62 INCHES WHICH IS -0.71 INCHES BELOW NORMAL.
HOWEVER, 2.38 INCHES OF THAT MONTHLY TOTAL OCCURRED DURING THE LAST
WEEK. SO, FOR AT LEAST THE FIRST THREE WEEKS OF THE MONTH, MODERATE
DROUGHT CONDITIONS WERE EXPERIENCED THROUGHOUT THE GREATER ROCHESTER
METRO AREA. 1.43 INCHES WERE RECORDED ON THE 26TH, BUT DESPITE THAT
FAIRLY HEAVY RAIN EVENT, THERE WERE NO RECORDS SET FOR THE MONTH.
WIND SPEEDS AVERAGED NEAR NORMAL, WITH A PEAK GUST OF NEAR 39-40 MPH
ACHIEVED ON THE 17TH, 23TH, AND 31ST.

THE MONTH WILL BE REMEMBERED AS A CONTINUATION OF A GENERALLY WARM AND
DRY YEAR FOR THE ROCHESTER AREA.
