What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tallahassee, FL wrote its last area forecast discussion before this special weather statement went out at Aug 3, 3:13 PM EDT, 2 hours 33 minutes earlier.

Area forecast discussion, Aug 3, 3:13 PM EDT, 2 hours 33 minutes before
Area Forecast Discussion
National Weather Service Tallahassee FL
313 PM EDT Sat Aug 3 2019

.NEAR TERM [Through Tonight]...

Scattered convection will continue into the evening hours before
diminishing overnight. With precipitable water values near 2 inches
as observed on the 12z KTAE sounding in addition to weak steering
flow, isolated pockets of heavy rain are possible. Overnight lows
will generally be in the 70s.

.SHORT TERM [Sunday Through Monday Night]...

An upper level long wave trough is in place aloft of the eastern
CONUS with a ribbon of PV that stretches across the north-central
Gulf waters and into the tri-state area on Sunday. Though the trough
will remain in place, the PV anomaly will lift northeastward Monday.
This upper level feature will continue to enhance seabreeze
convection for the next couple of days. PW values in the 1.5-2" will
be common across the forecast area, with a few spots over 2".
Rainfall totals will generally be around 1 inch, but locally higher
amounts of 2 to 4 inches remain possible. This could lead to
localized flooding during slow moving thunderstorms for the next few
days. Highs will be in the low 90s and lows will be in the low 70s.

.LONG TERM [Tuesday Through Saturday]...

The upper level long wave trough over the eastern CONUS should
finally shift eastward late in the week, with a weak pressure
pattern remaining in place at the low levels. PoPs will generally
hang around the 40-50% range through Thursday, finally lowering to
30-40% for Friday and Saturday. Highs will be in the low-mid 90s and
lows will be in the low-mid 70s.

&&

.AVIATION...
[Through 18Z Sunday]

Scattered showers and thunderstorms across the area are expected
to continue into this evening and diminish overnight. Mainly VFR
conditions are expected away from convection.

&&

.MARINE...

Light winds from the west will prevail through most of the period
with seas of 1 to 2 feet. The only weather concern for mariners
for the next several days will be daily chances for showers and
thunderstorms.

&&

.FIRE WEATHER...

No critical fire weather conditions are expected over the next
several days.

&&

.HYDROLOGY...

Local rivers are below action stage. A wet pattern will be in place
through Monday. Slow moving storms may produce some localized
flooding today. Ponding of water on roadways and flooding of low
lying areas is likely with the stronger storms.

&&

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @NWSTallahassee.
