REMARKS...

2012 WILL BE REMEMBERED FOR EXTREME WARMTH. THE AVERAGE TEMPERATURE
FOR THE YEAR WAS THE HIGHEST FOR ANY YEAR ON RECORD. THE MAGNITUDE
OF HOW FAR ABOVE NORMAL IS PUT IN PERSPECTIVE BY THE FACT THAT THE
YEARS WITH THE FOLLOWING NINE WARMEST AVERAGE TEMPERATURES WERE
WITHIN ONE DEGREE OF EACH OTHER...BUT WERE ALL OVER ONE DEGREE BELOW
THAT OF 2012.

- TOP TEN WARMEST YEARS -

           AVERAGE
  RANK - TEMPERATURE - YEAR
----------------------------------------
   1   -    59.8 F   - 2012
   2   -    58.7 F   - 1938
   3   -    58.6 F   - 1939
 TIE 4 -    58.5 F   - 1934, 1946
   6   -    58.1 F   - 1931
   7   -    57.9 F   - 1933
 TIE 8 -    57.8 F   - 1921, 1954, 2006

THE LOWEST TEMPERATURE MEASURED IN 2012 WAS 8 DEGREES. THIS BREAKS
THE RECORD FOR THE HIGHEST MINIMUM TEMPERATURE FOR A YEAR. THE
PREVIOUS RECORD WAS 6 DEGREES...IN 1931. BREAKING DOWN THE WARMTH BY
MONTHS...EIGHT OF THE TWELVE MONTHS RANKED IN THE TOP TWENTY OF
THEIR WARMEST VALUES...AND SIX MONTHS IN THEIR RESPECTIVE TOP TEN.
THE BULK OF THE ABOVE NORMAL TEMPERATURES TOOK PLACE FROM MARCH
THROUGH JULY. MARCH 2012 WAS THE WARMEST MARCH ON RECORD AND MAY WAS
THE SECOND WARMEST MAY ON RECORD. THE AVERAGE TEMPERATURE FOR MARCH
WAS 14.5 DEGREES ABOVE NORMAL AT 59.3 DEGREES...WHICH IS NEAR THE
NORMAL AVERAGE TEMPERATURE OF LATE APRIL. DAILY RECORDS FOR THE
HIGHEST MAXIMUM OR HIGHEST MINIMUM TEMPERATURE WERE SET OR TIED ON
26 OCCASIONS...EIGHT OF THOSE OCCURING IN MARCH. THE LAST DAY THE
MERCURY FELL TO AT OR BELOW THE FREEZING POINT IN THE SPRING WAS
MARCH 9...WHICH IS THE EARLIEST OCCURRENCE OF THE LAST FREEZE ON
RECORD...ECLIPSING THE PREVIOUS RECORD OF MARCH 10...1946. THE
LOWEST TEMPERATURE MEASURED ON MARCH 18...69 DEGREES...TIED THE
RECORD FOR THE HIGHEST MINIMUM TEMPERATURE FOR ANY MARCH DAY. THE
SAME SUCH RECORD OCCURED ON MAY 26 WHEN THE LOWEST TEMPERATURE WAS
76. THE APRIL 25 HIGH TEMPERATURE OF 97 TIED FOR THE HIGHEST MAXIMUM
ON RECORD FOR THAT MONTH...AND TWO OTHER DAYS IN APRIL SAW THE
MERCURY REACH AT LEAST 90 DEGREES WHICH TIED FOR THE MOST TIMES OF
THIS HAPPENING IN APRIL. THE WARMEST FIVE...SIX...AND SEVEN DAY
PERIODS FOR MAY WERE SET IN LATE MAY 2012...AND THE MAY 1 THROUGH
MAY 6...2012 PERIOD WAS THE WARMEST SUCH PERIOD ON RECORD. THE JULY
AVERAGE TEMPERATURE OF 86.3 DEGREES PLACED IT AS THE SEVENTH WARMEST
MONTH ON RECORD AND INCLUDED SIXTEEN DAYS WITH HIGHS OF AT LEAST 100
DEGREES.

IN TERMS OF CLIMATOLOGICAL SIGNIFICANCE...NOT TOO FAR BEHIND THE WARM
TEMPERATURES OF 2012 WAS THE LACK OF PRECIPITATION. THE 23.06 INCHES
OF PRECIPITATION WAS THE TENTH LOWEST ANNUAL TOTAL ON RECORD.

- TOP TEN DRIEST YEARS -

   9  -  22.33 INCHES - 1939
  10  -  23.06 INCHES - 2012

ONLY TWO MONTHS HAD PRECIPITATION TOTALS ABOVE NORMAL...INCLUDING
FEBRUARY WITH THE EIGHTH HIGHEST AMOUNT ON RECORD FOR THAT
MONTH...AND CONVERSELY ONLY TWO MONTHS WERE IN THE BOTTOM TWENTY IN
TERMS OF TOTAL PRECIPITATION FOR THEIR RESPECTIVE MONTHS. THE TOTAL
AMOUNT OF SNOW RECEIVED WAS THE FIFTEENTH LOWEST AMOUNT ON RECORD.
NOT ONLY WAS THE OVERALL AMOUNT OF PRECIPITATION LACKING...THE
NUMBER OF DAYS THAT MEASURABLE PRECIPITATION FELL ALSO WAS
RECORD-BREAKING. ONLY 69 DAYS HAD MEASURABLE PRECIPITATION...SETTING
THE RECORD.
