...July 2017 was Warmer Than Normal with Near to Above Normal
Rainfall Across East Central Florida...

Scattered showers and storms occurred across east central Florida on
an almost daily basis, which is typical for this time of year. This
combined with more widespread heavy rainfall from remnants of
Tropical Depression Four mid month and Tropical Cyclone Emily on the
last day of July, helped produced rainfall amounts that were near to
above normal for much of the region.

Decent coverage of convection and increase in cloud cover from this
activity kept high temperatures closer to normal most afternoons,
while humid conditions and periods of onshore flow helped contribute
to overnight lows that were often warmer than normal. Overall, this
led to average temperatures for July that were above normal, with
most sites across the region ranking in the top 10 warmest.

...Temperatures...

The east coast sea breeze developed by early afternoon and moved
inland most days, and there were limited periods of low storm
coverage during the month. This generally kept daily max
temperatures near to just above normal, frequently ranging from the
low 90s along the coast and low to mid 90s over the interior. Lows
were often above normal, in the mid to upper 70s, especially along
the coast, with numerous warm minimum temperatures tied or broken
throughout July.

Most climate sites across the region had average temperatures for
the month that were 1 to 2 degrees warmer than normal, which ranked
in their respective top 10 warmest on record. Melbourne was the most
notable, with this July ranking as their 2nd warmest on record. This
was just two tenths of a degree shy of their record warmest July set
just last year! Orlando was the main outlier, with a monthly average
temperature that was near a half a degree below normal.

Average temperature values for July 2017 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 82.8 degrees
Fahrenheit, which was 1.2 degrees above normal. This ties 1981,
1969, and 1930 as the 7th warmest July on record for this site, with
records extending back to 1923.

-Orlando had a monthly average temperature of 82.3 degrees
Fahrenheit, which was 0.4 degrees below normal.

-Melbourne had a monthly average temperature of 84.3 degrees
Fahrenheit, which was 2.6 degrees above normal. This ranks as the as
the 2nd warmest July on record for this site, with records extending
back to 1937.

-Vero Beach had a monthly average temperature of 83.3 degrees
Fahrenheit, which was 1.6 degrees above normal. This ranks as the as
the 4th warmest July on record for this site, with records extending
back to 1942.


...Rainfall...

Ridge axis of high pressure over the west Atlantic was typically
near to north of the region during the first half of the month,
focusing greatest coverage of convection and locally heavy rainfall
across the interior. However, an easterly wave that was the remnant
of Tropical Depression Four pushed westward across the state on the
12th of July, and led to a significant increase in heavy rainfall
along the coast from the Cape southward. Many locations in this area
received amounts between 1 to 3 inches, with Melbourne and Vero
Beach setting new daily rainfall records.

Into the latter half of the month the ridge axis generally remained
across the southern Florida peninsula, which steered scattered
showers and storms across east central Florida and toward the coast.
A weak front pushed toward central Florida toward the end of July,
increasing moisture and rainfall. Then an area of low pressure
developed along this boundary, across the eastern Gulf early on the
31st, and quickly strengthened into Tropical Storm Emily. This
system pushed eastward across central Florida as it gradually
weakened to a depression, and produced 1 to 3 inches of
precipitation for many locations, with locally higher amounts of 4
to 6 inches in some spots.

Scattered showers and storms most days and the periods of tropical
heavy rainfall, led to near to above normal precipitation in July for
much of the area.

Orlando:
-July 17th: Record daily rainfall of 3.09 inches. Previous record
