Area Forecast Discussion
National Weather Service Jacksonville FL
319 AM EDT Sat May 27 2017

.NEAR TERM /Through tonight/...

A mid/upper ridge will build in across the area with a surface ridge
across south Fl. This will bring hot and dry conditions to the area
with a light southwest flow. Temps reaching the lower to mid 90s
most areas away from the coast. Afternoon seabreeze keeping coastal
areas in the mid/upper 80s. Low level moisture begins to advect in
from the gulf tonight which results in patchy late night and early
morning fog especially near the I-75 corridor of Ne Fl.

.SHORT TERM /Sunday-Monday/...

High pressure over the eastern Gulf of Mexico will dominate the
pattern on Sunday with slightly above normal temps especially across
interior areas. An upper level short wave trough will begin to dig
into the central Mississippi River Valley. On Monday the upper ridge
remains well entrenched across the Florida portion of the area but
the digging trough erodes the northwest periphery of the ridge over
Georgia and we could see a few showers over the Altamaha River
counties..

.LONG TERM /Monday night thru Friday/...

Early in the week the area remains between the upper level ridge
over Florida and the Atlantic and the large upper tough over the
Great Lakes. This should allow some Gulf moisture to sneak over the
area with 30 to 40 percent afternoon and evening pops. Temperatures
will be in the lower to mid 90s across the interior and in the upper
80s along the coast. By Thursday and Friday the ridge pushes
offshore with a quasi-stationary frontal system lying east-west near
the Florida-Georgia State Line. This will increase the rain chances
for late in the week. With increased moisture, temperatures will top
out near 90 inland and in the mid 80s along the coast.

&&

.AVIATION...Prevailing VFR.

&&

.MARINE...A surface ridge south of the waters will produce a
southwest flow the next few days with afternoon seabreezes near
shore in the afternoon and early evenings. Slightly stronger winds
in the early evening but below headline criteria. A frontal boundary
will wash out across the waters towards mid week producing variable
winds with afternoon and evening seabreezes.

Rip Currents: Low risk through Sunday.
