... September 2016 was warmer than normal across east central
Florida...

Early in September, tropical cyclone Hermine and a lingering frontal
boundary in the wake of this system increased rainfall and kept
temperatures generally closer to normal. Then into middle and late
month, scattered showers and storms occurred on an almost daily
basis with temperatures remaining near to above normal. Above normal
temperatures, however, were more dominant during this period,
leading to warmer than normal conditions overall. The more scattered
nature of showers and storms during the month led to varying
precipitation totals across the region, but much of the area had
rainfall amounts near to above normal.

Temperatures...

Temperatures in September were often a few degrees warmer than
normal, with highs reaching the upper 80s to low 90s most days and
lows in the low to mid 70s. Some brief periods of near to slightly
cooler than normal temperatures also occurred, especially early in
the month with increased cloudiness and rainfall associated with
Hermine and drier air that built in behind a front left in the
systems wake.

Average monthly temperature values were around one and a half
degrees above normal, ranking this September in the top ten warmest
for all primary climate sites.

Daily record temperatures for the month:

Orlando:
-September 18th: tied record warm low of 76 degrees last set in 1990.

Melbourne:
-September 7th: tied record warm low of 79 degrees last set in 1956.


Average temperature values for September 2016 at the four primary
climate sites across east central Florida are as follows (rankings
provided if in the top 10):

-Daytona Beach had a monthly average temperature of 80.8 degrees
fahrenheit, which was 1.3 degrees above normal. This ties 2005,
1991, 1973 and 1931 as the 7th warmest September on record for this
site. Records for this site go back to 1923.

-Orlando had a monthly average temperature of 82.2 degrees
fahrenheit, which was 1.1 degrees above normal. This ties 2002 and
1989 as the 9th warmest September on record for this site. Records
for this site go back to 1892.

-Melbourne had a monthly average temperature of 81.8 degrees
fahrenheit, which was 1.2 degrees above normal. This ties 2002 as
the 4th warmest September on record for this site. Records for this
site go back to 1937.

-Vero Beach had a monthly average temperature of 82.2 degrees
fahrenheit, which was 1.6 degrees above normal. This ranks as the
second warmest September on record for this site, just three tenths
of a degree shy of the record set in 1996 of 82.5 degrees. Records
for this site go back to 1942.


.Rainfall...

Outer rainbands from Hermine produced widespread rainfall across the
region during the first couple days of September, but totals were
generally around a half an inch or less except across lake and
Volusia counties where amounts reached up to 1 to 2 inches. Deep
moisture and a lingering boundary across the region as Hermine
lifted northeast and away from the area, kept higher coverage of
showers and storms over central Florida through the 5th. Then as the
boundary shifted south, drier air built in and produced lower than
normal coverage of afternoon convection for several days. A tropical
low, which later became Tropical Storm Julia as it lifted north of
the area, brought additional widespread rainfall toward mid month,
with locally higher amounts along the coast. A more typical wet
season like pattern than followed through the remainder of
September, with isolated to scattered sea breeze generated showers
and storms in the afternoon and evening hours most days.

Since rainfall coverage was often scattered and locally heavy at
times, precipitation amounts for September varied across east
central Florida. However much of the area had end of month rainfall
totals that were near to above normal, expect for portions of
interior Volusia County and the Treasure Coast where rainfall
amounts were generally 1 to 2 inches below normal. A couple of
extreme exceptions that characterize the significant differences in
precipitation this month were Melbourne and Stuart. Melbourne had
its 6th wettest September on record with 14.17 inches of rain and
Stuart only received 3.35 inches, ranking as the 7th driest
September on record for this site.

Daily record rainfall for the month:

Orlando:
-September 4th: record rainfall of 2.32 inches. Previous record was
1.95 inches set in 1905.

Melbourne:
-September 13th: record rainfall of 3.51 inches. Previous record was
3.40 inches set in 1976.
-September 19th: record rainfall of 3.58 inches. Previous record was
1.85 inches set in 1998.


September 2016 rainfall totals for the four primary climate sites
across east central Florida are as follows (ranking provided if in
the top 10):

-Daytona Beach received 8.24 inches of rain for the month, which was
1.28 inches above normal.

-Orlando received 7.26 inches of rain for the month, which was 1.20
inches above normal.

-Melbourne received 14.17 inches of rain for the month, which was
6.53 inches above normal. This ranks as the 6th wettest September on
record for this site.

-Vero Beach received 4.90 inches of rain for the month, which was
1.89 inches below normal.

Co-Operative observer station rainfall rankings:
-Stuart had 3.35 inches of rain for the month, which ranks as the
7th driest September on record. Records for this site go back to
1909.
