Area Forecast Discussion
National Weather Service Jacksonville FL
350 PM EDT Thu Jul 20 2017

.NEAR TERM...
Rest of the afternoon into Tonight...isolated to scattered
convection expected with isolated storms strong to possibly severe
given the amount of instabilty that is building up. SBCAPE noted
peaking out around 3500-4000 J/kg and DCAPE of about 1000 J/kg.
Activity should be moving roughly south to southwest at about 10
knots. Main threats will be brief damaging wind gust and some hail.
Activity should be winding down by 11 pm or so as the low levels
continue to cool. Some guidance suggests indicates patchy fog over
NE FL and mentioned some fog near the I-75 corridor late tonight.
Lows in the lower to mid 70s. Upper level low, off the NE FL coast,
is expected to be moving through NE FL this evening and begin to
drift slowly west Friday.

Friday...sfc ridge stays to our south, while mid to upper level low
drifts west toward the FL panhandle/SW GA/SE AL later in the day.
Better forcing associated with being on the eastern side of the
upper level combined with sufficient moisture, though only near the
average for July at about 1.7 inches will lead to scattered aftn
showers and storms again. Best favored areas will be around the I-75
corridor up into inland SE GA. Highs will be in the lower to mid 90s.

.SHORT TERM /Saturday and Sunday/...

Our area will be between upper low to our west and upper high to our
east. Steering flow will become southwesterly. Hot and humid
conditions will prevail, especially on Saturday with lower than
normal thunderstorm activity expected. Isolated to widely scattered
storms on Saturday shifting east during the day and continuing deep
into the evening hours. Convection will become more scattered to
numerous on Sunday across northeast Florida.

.LONG TERM /Monday through Thursday/...

Model blend yields at or below normal temps early in the week, then
at or slightly below normal by mid to late week as thunderstorm
coverage increases with upper low moving back into the region. Light
offshore flow will continue through the week. Scattered storms
expected early in the week becoming numerous Wednesday and Thursday,
especially along and north of the I-10 corridor.

&&

.AVIATION...
A few showers and storms expected around the TAF sites rest of the
aftn except probably not for SGJ and CRG as the east coast sea
breeze has moved well inland. Showers and storms will end through
the late evening, with prevailing VFR continuing. Some fog may sneak
into GNV late tonight but lower confidence suggests to leave out at
this time. Another round of showers and storms Friday mainly in
aftn.

&&

.MARINE...
Surface ridge axis will remain south of the area through early next
week. We expect southwest flow through Saturday then becoming
southeast as the Atlantic sea breeze develops. Seas will generally
remain in the 2 to 4 foot range with winds and seas below Small
Craft Exercise Caution criteria. Somewhat stronger southwest flow
Sunday through early next week may mute the east coast sea breeze a
bit...as a sfc trough and front push into the Carolinas and possibly
north GA.

Rip Currents: Mainly low risk, though rip currents will be more
prevalent around piers and jetties.
