Area Forecast Discussion

317 PM EDT Sat Jun 12 2021

.Short Term.../through Monday/...

A cold front will move into SE GA this afternoon, then nearly
stationary near the GA/FL line through Tonight. The area will also
be in the base of an 500mb trough through Tonight. The combination
of diurnal heating, frontal convergence, and upper energy will
provide for an increased chance for convection this afternoon and
evening. While the activity will decrease in coverage through the
night due to loss of diurnal heating, storm chances will linger.

On Sunday, the cold front will remain across the region with the
500mb trough in place. Scattered to numerous storms will be expected
once again.

The frontal boundary will sink to the southeast and weaken Sunday
night.

For Monday, the upper trough will remain over the region, with the
combination of diurnal heating and upper support leading to
scattered to numerous storms. The best chance will be across NE FL,
closer to the dissipating cold frontal zone.

Temperatures will trend around seasonal averages this period.

&&

.Long Term.../Monday night through Saturday/...

Another frontal boundary will slide southeast into SE GA Monday
night. The boundary will move to near the GA/FL line Tuesday and
stall through Thursday. Above average coverage of showers and storms
will be expected through Thursday due to the frontal convergence and
diurnal instability. The greatest chance for storms will be across
NE FL.

Another trough will be over the region Friday into Saturday,
enhancing the diurnally driven convective activity.

Temperatures will trend near to a little above normal early in the
period, then near to a little below.

&&

.Marine...

A few troughs will affect the region over the next week, leading
to a period with above average chances for showers and storms.

Rip Currents: SE GA: Low through Sunday
              NE FL: Low through Sunday
