PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE KEY WEST FL
433 PM EDT TUE MAY 7 2013

...AN ABNORMALLY WARM APRIL OBSERVED IN THE FLORIDA KEYS...

IN CONTRAST TO THE MONTH OF MARCH...THE MONTH OF APRIL IN THE
FLORIDA KEYS WAS ABNORMALLY WARM. AT KEY WEST...THE MONTH OF APRIL
2013 WAS THE 9TH WARMEST SINCE RECORDS BEGAN IN 1872. THE AVERAGE
TEMPERATURE DURING APRIL AT THE KEY WEST INTERNATIONAL AIRPORT WAS
79.6 DEGREES WHICH WAS 3.0 DEGREES ABOVE THE 30-YEAR NORMAL VALUE OF
76.6 DEGREES. AT MARATHON...THE AVERAGE TEMPERATURE WAS 81.6 DURING
APRIL WHICH IS CORRESPONDINGLY 4.3 DEGREES ABOVE NORMAL.

RAINFALL DURING THE MONTH OF APRIL WAS UNEVENTFUL WITH ONLY SIX DAYS
OF MEASURABLE RAINFALL RECORDED. THE HIGHEST RAINFALL TOTAL WAS ON
APRIL FIFTH WITH 1.41 INCHES OF RAIN AT THE KEY WEST INTERNATIONAL
AIRPORT. THE MONTHLY TOTAL...2.12 FOR KEY WEST...WAS FAR LESS THAN
THE RECORD OF 12.00 INCHES SET IN APRIL 1985.

ONE OF THE MORE INTERESTING FEATURES FOR THE MONTHLY CLIMATE RECORD
IS THE FACT THAT KEY WEST INTERNATIONAL AIRPORT TIED...OR EXCEEDED
THE DAILY RECORD WARM MINIMUM TEMPERATURE FOR A PERIOD OF 9
CONSECUTIVE DAYS DURING THE MIDDLE OF THE MONTH. THIS PROLONGED
PERIOD OF WARM OVERNIGHT LOW TEMPERATURES WAS ENCOURAGED BY SERIES
OF LONG-LIVED ATLANTIC RIDGES THAT INDUCED PERSISTENT EAST
SOUTHEASTERLY FLOW ACROSS THE ISLAND CHAIN. CONSEQUENTLY...
ABNORMALLY MOIST CONDITIONS DURING THAT PERIOD LIMITED THE DIURNAL
RANGE OF TEMPERATURES THAT WERE OBSERVED. BELOW ARE THE DAILY RECORD
WARM MINIMUM VALUES THAT WERE SET THAT WERE MET OR EXCEEDED DURING
THAT PERIOD. RECORDS OF NO OTHER TYPE WERE SET DURING THE MONTH. ALL
VALUES ARE PROVIDED IN DEGREES FAHRENHEIT.
