...WELL ABOVE NORMAL RAINFALL OCCURRED ACROSS EAST CENTRAL FLORIDA
DURING SEPTEMBER 2014...

ATLANTIC HIGH PRESSURE RIDGE DOMINATED INTO THE FIRST HALF OF
SEPTEMBER WITH NEAR TO ABOVE NORMAL TEMPERATURES AND SCATTERED
AFTERNOON CONVECTION MOST DAYS. THEN A WEAK FRONTAL BOUNDARY MOVED
INTO THE REGION AND LINGERED THROUGH THE LATTER HALF OF THE MONTH
INCREASING SHOWER AND THUNDERSTORM COVERAGE. SEVERAL DAYS OF
WIDESPREAD RAINFALL LED TO WELL ABOVE NORMAL PRECIPITATION ACROSS
THE REGION WITH AVERAGE TEMPERATURES NEAR TO BELOW NORMAL.


.TEMPERATURES...

FOR THE FIRST HALF OF SEPTEMBER TEMPERATURES WERE GENERALLY NEAR TO
SLIGHTLY ABOVE NORMAL ACROSS MUCH OF THE REGION. OVERALL HIGHS
RANGED FROM THE UPPER 80S TO LOW 90S AND LOWS WERE IN THE LOW TO MID
70S. HOWEVER INTO THE LATTER HALF OF THE MONTH CONVECTION AND CLOUD
COVER INCREASED DUE TO A FRONTAL BOUNDARY THAT STALLED AND LINGERED
ACROSS THE REGION. THIS KEPT TEMPERATURES NEAR TO SLIGHTLY BELOW
NORMAL WITH HIGHS MANY DAYS FROM THE 17TH THROUGH THE 30TH ONLY
REACHING THE LOW TO MID 80S. SEVERAL LOCATIONS ALSO SAW LOWS IN THE
UPPER 60S DURING THIS TIMEFRAME. AT ORLANDO AND SANFORD EARLY ON THE
25TH...TEMPERATURES DROPPED TO 69 DEGREES WHICH WAS THE FIRST TIME
THESE SITES SAW LOWS BELOW 70 DEGREES SINCE EARLY JUNE.

OVERALL MONTHLY TEMPERATURE DEPARTURES WERE WITHIN A HALF A DEGREE
OF NORMAL. THE EXCEPTION WAS VERO BEACH WITH A MEAN TEMPERATURE THAT
WAS ALMOST TWO DEGREES BELOW NORMAL AND TIED FOR THEIR THIRD
COOLEST SEPTEMBER ON RECORD.

.RAINFALL...

AFTER COMING OUT OF A DRIER THAN NORMAL AUGUST...A WETTER PATTERN
SET UP OVER EAST CENTRAL FLORIDA INTO SEPTEMBER. BELOW NORMAL
COVERAGE OF SHOWERS AND STORMS WERE INITIALLY OBSERVED THE FIRST FEW
DAYS OF THE MONTH DUE TO A DRIER AIRMASS IN PLACE. HOWEVER DEEPER
MOISTURE AND AN INVERTED TROUGH ALOFT THAT MOVED INTO THE REGION
INCREASED CONVECTIVE COVERAGE FOR SEVERAL DAYS EARLY IN SEPTEMBER.
LOCALLY HEAVY RAINFALL WAS OBSERVED AT TIMES WITH DAYTONA BEACH
RECEIVING 3.54 INCHES OF RAIN ON THE 7TH...BREAKING THEIR DAILY
RAINFALL RECORD.

SHOWER AND STORM COVERAGE REMAINED FAIRLY NORMAL THROUGH THE MIDDLE
PORTION OF THE MONTH BEFORE A WEAK FRONTAL BOUNDARY MOVED INTO
CENTRAL FLORIDA ON THE 19TH AND STALLED ACROSS THE STATE. DEEPER
MOISTURE ASSOCIATED WITH THIS BOUNDARY AND A DISTURBED WEATHER
PATTERN ALOFT LED TO HIGH COVERAGE OF SHOWERS AND STORMS ACROSS THE
REGION. AN EXTENDED PERIOD OF ABOVE NORMAL RAINFALL OCCURRED THROUGH
MUCH OF THE REST OF SEPTEMBER AS A QUASI-STATIONARY FRONT LINGERED
OVER THE FLORIDA PENINSULA AND KEPT DEEP MOISTURE IN PLACE.
WIDESPREAD RAINFALL...HEAVY AT TIMES...LED TO MORE SIGNIFICANT
FLOODING OF ROADWAYS AND LOW LYING AREAS IN SOME LOCATIONS. THIS WAS
ESPECIALLY TRUE ALONG THE VOLUSIA COUNTY COAST THROUGH THE EVENING
OF THE 23RD INTO THE EARLY MORNING OF THE 24TH WHERE RAINFALL
AMOUNTS UP TO 6 TO 8 INCHES OCCURRED FROM PERSISTENT CONVECTION.
DAYTONA BEACH HAD THE HIGHEST 24 HOUR RAINFALL TOTAL (ENDING AT 8 AM
ON THE 24TH) OF 7.95 INCHES. THE HEAVIER PRECIPITATION IN THE LATTER
HALF OF SEPTEMBER ALSO CAUSED THE ST. JOHNS RIVER AT ASTOR TO GO
INTO MINOR FLOOD STAGE.

NORMAL WITH DEPARTURES BETWEEN 3 TO 5 INCHES ABOVE NORMAL AT MANY
SITES. MOST NOTEWORTHY EXCEPTION WAS DAYTONA BEACH WHICH HAD THEIR
