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 Jacksonville, FL wrote its last area forecast discussion before this special weather statement went out at Aug 1, 3:28 PM EDT, 42 minutes earlier.

Area forecast discussion, Aug 1, 3:28 PM EDT, 42 minutes before
Area Forecast Discussion
National Weather Service Jacksonville FL
328 PM EDT Sun Aug 1 2021

.Near Term.../through Monday/...

High pressure will be southeast of the area Today, with a frontal
zone just to the north. Scattered to numerous convection anticipated
this afternoon and evening. The front will sink southeast Tonight
into SE GA counties, which could keep activity going into the
overnight hours.

The surface front will stall over area during the day Monday, as
500mb trough digs into southeastern US. The combination of diurnal
heating, convergence along the front and added instability
associated with upper trough will yield a fairly active convective
day on Monday. With the surface flow largely running along the
surface boundary could see rounds of heavy rainfall training over
the region. So, in addition to potential for strong to a few severe
storms Monday afternoon, will also anticipate localized flooding.

Temperatures Tonight will trend above normal, with a near to
slightly below normal day on Monday.

&&

.Short Term.../Monday night through Thursday/...

The region remains in the base of a 500mb trough with a stalled
frontal zone at the surface in place through Wednesday. This pattern
will continue the stormy period, with rounds of convection expected.

The pattern begins to change into Thursday, as the upper trough
flattens, and the surface frontal zone lifts back to the north, as
surface high pressure builds toward east. While it will still be
moist and unstable enough for diurnally driven convection on
Thursday, the chances will begin to trend down.

Overnight lows will be near normal this period, while highs will
trend below normal due to rain and cloud coverage.

&&

.Long Term.../Thursday night through Sunday/...

High pressure will extend across the area from a center to the east
this period. While convective chances will be a little lower than
earlier in the week, chances will still be higher than average.

Temperatures will trend near normal at night, and a little below
normal for highs.

&&

.Marine...

A frontal boundary will sink southeast into area Tonight, and stall
through Wednesday. The boundary will lift back to the north and
weaken later in the week, as high pressure builds toward the east.

Rip Currents: Low through Monday.
