...Rainfall Was Above Normal with Temperatures Near to Above Normal
Across East Central Florida During April 2021...

A cold front that crossed the area at the beginning of April, led to
a colder than normal start to the month. A lingering front toward
mid-month produced increased cloud cover and rainfall which in turn
also produced some cooler weather across the area during this
period. However, near to above normal temperatures largely prevailed
for much of April. Periods of heavy rainfall from the aforementioned
frontal boundary that meandered across the Florida peninsula, and a
complex of strong to severe storms that moved through ahead of a
passing cold front on the 11th, produced much of the precipitation
that fell in April. With April typically being one of the driest
months for central Florida, the widespread heavier rainfall from
these events easily produced well above normal precipitation across
the area.


...Temperatures...

A stronger cold front pushed southward across the area on the 1st,
which led to a period of cooler than normal weather for the start of
April. Daily average temperatures plummeted to 10 to 15 degrees
below normal the following day, with highs in the 60s to low 70s.
Daytona Beach actually broke their record cool high for the 2nd,
with the maximum temperature only reaching 60 degrees at this site.
Dry and cool conditions continued for several days thereafter, with
highs typically in the 70s and lows in the upper 40s and into the
50s.  Temperatures then warmed to near to above normal values before
a large area of showers and strong to severe storms pushed through
the region on the 11th, ahead of another cold front. Highs didnt
get out of the 60s north of Orlando that day, with Sanford tying
their record cool high of 68 degrees, while along the Treasure Coast
highs reached the mid to upper 80s ahead of the stormy weather.

A cold front moved into north Florida early on the 16th and then
lingered across the state as it shifted south and north across the
Florida peninsula for several days. This produced periods of
increased cloud cover and rounds of showers and storms that at times
led to cooler than normal temperatures across the region. However,
overall temperatures were mostly near to above normal through this
period and especially into the end of the month when highs generally
remained in the 80s to low 90s.

The cooler periods at the start of the month and again around the
middle of April, helped offset periods of near to above normal
warmth. This led to average temperatures for April ending up
generally near to slightly above normal, ranging from 0.2 degrees
below normal at Sanford and up to 1.9 degrees above normal at
Melbourne.


Daily Record Temperatures for the Month:

Daytona Beach:
- April 2nd: Record cool high of 60 degrees. Previous record was 62
degrees last set in 1996.

Vero Beach:
- April 17th: Record high of 91 degrees. Previous record was 90
degrees last set in 2006.
- April 24th: Tied record warm low of 73 degrees last set in 2011.

Average temperatures for April 2021 at the primary climates
across east central Florida are as follows (rankings provided if in
the top 10):

- Daytona Beach had a monthly average temperature of 69.5 degrees
Fahrenheit, which was 0.6 degrees above normal.

- Leesburg had a monthly average temperature of 71.3 degrees
Fahrenheit, which was 0.4 degrees above normal.

- Sanford had a monthly average temperature of 71.2 degrees
Fahrenheit, which was 0.2 degrees below normal.

- Orlando had a monthly average temperature of 71.8 degrees
Fahrenheit, which was 0.6 degrees above normal.

- Melbourne had a monthly average temperature of 72.3 degrees
Fahrenheit, which was 1.9 degrees above normal.

- Vero Beach had a monthly average temperature of 72.1 degrees
Fahrenheit, which was 1.2 degrees above normal.

- Fort Pierce had a monthly average temperature of 72.0 degrees
Fahrenheit, which was 0.9 degrees above normal.


...Rainfall...

Showers and isolated storms moved through Okeechobee County and the
Treasure Coast on the 1st as a cold front pushed southward through
the region. Otherwise, mostly dry conditions followed through the
9th. Increasing moisture well ahead of an approaching front
generated additional showers and strong storms on the 10th. However,
significant widespread rainfall occurred on the 11th as an organized
squall line of strong to severe storms moved through central
Florida. Most locations reported precipitation totals of 1 to 2
inches with this activity across east central Florida, with some
locally higher totals of 3 to 4 inches. Fort Pierces total of 2.05
inches set a daily rainfall record for that day.

After a cold front moved through after the passage of the previously
mentioned squall line, dry conditions then prevailed for a few days
following. Another front then pushed into central Florida on the
16th and lingered across the Florida peninsula through the 21st.
This boundary helped initiate several rounds of showers and storms
across the area during this timeframe, initially near to north of
Orlando on the 16th and 17th, and then covering much of central
Florida each day from the 18th through the 20th. Rainfall totals for
this entire period ranged from 1 to 4 inches for many locations,
except around a half an inch or less across Martin and southern St.
Lucie counties. A handful of daily rainfall records were also broken
during this time at Leesburg, Sanford and Orlando (records below).

For the remainder of the month, despite some showers and isolated
storms on the 25th ahead of a passing front and some additional
rainfall south of Orlando on the 29th and 30th, dry conditions
mostly prevailed. The above normal rainfall from the squall line on
the 11th, and the showers and storms associated with the lingering
frontal boundary around to just after mid-month, largely contributed
to April 2021 being wetter than normal. Monthly rainfall amounts
generally ranged from 3 to 6 inches across much of east central
Florida, with locally higher amounts up to around 7 inches.  With
April typically being one of our drier months, with normal rainfall
around 2 to 3 inches, these totals were easily one and a half to 3
times higher than that. For Leesburg, DeLand, Orlando, and
Titusville, this April ranked among the top 10 wettest on record
(see rankings below).
