Area Forecast Discussion
National Weather Service Jacksonville FL
317 PM EDT Tue Jun 23 2020

.Short Term.../through Saturday/...

The region will be in the base of an upper trough through Wednesday.
With the upper low pretty far to the north, the flow through the
troughs base will be pretty progressive, allowing a series of
surface troughs to move east through the flow. The first of these
troughs will continue to pass through this afternoon, aiding in the
diurnally intitiated convective chances. Another surface trough will
move through SE GA Wednesday, with weak ridging at the surface and
aloft over NE FL. So, expect best chances for convection Wednesday
across SE GA.

High pressure builds at the surface and aloft Thursday into Saturday.
While can not rule out afternoon and evening convection due to
diurnal instability and sea breeze interactions the chances will be
less than normal.

Temperatures will trend above normal this period. The west southwest
flow will limit the push of the east coast sea breeze Wednesday and
Thursday, pushing readings above 90 all the way to the beach
communities. The flow will be more south to southeast Friday into
Saturday, which will allow the east coast sea breeze to push further
inland, helping to cap highs east of I95 to around 90.

&&

.Long Term.../Saturday night through Tuesday/...

The upper ridge will flatten late in the weekend, but surface
ridging will remain. The potential for convection will exist Sunday
due to diurnal instability and sea breeze interactions, but chances
will be lower than normal. Troughing at the surface and aloft will
extend south across the region from a low in the northeast early in
the week, which will increase chances for mainly afternoon and
evening storms.

The above normal temperature trend will continue this period.

&&

.Marine...

High pressure ridge will be southeast of the region through
Thursday, with troughing extending into area from the north. High
pressure will build over the area Friday through Sunday, with a
trough settling over region early next week.

Rip Currents: SE GA: Moderate risk Wednesday
              NE FL: Moderate risk Wednesday
