Area Forecast Discussion
National Weather Service Jacksonville FL
806 PM EDT Thu Aug 15 2019

.UPDATE...Evening radar shows heavier activity has cleared out
of eastern counties, with just patchy areas of light rain or
drizzle, while fairly good coverage of showers interior ne FL and
a band of convection over our northern counties in s-ctrl GA.
Think we will see a decrease in precip coverage later Tonight,
except for potentially an increase over interior ne FL before dawn
that will spread NE across ne FL during the day Friday. Low
temperatures Tonight should be in the mid 70s inland, upper 70s
coast.

&&

.AVIATION...Forecast a bit challenging, as have seen areas of IFR
CIGs not picked up by model guidance. Models suggest potential
for MVFR CIG to develop across the area Tonight, continuing
Friday, and this is reflected in latest TAFs, which will be
updated when local IFR conditions appear. Have included TEMPO for
TSRA during the period when most likely, but could see
showers/isolated TSRA in TAF sites during the late morning/midday
hours.

&&

.MARINE...The Atlantic ridge continues to be positioned to our south
over Bahamas and the FL straits through Friday, then should lift
a bit northward into Friday night into Sunday. Will see continued
south and southwest winds for the local waters. Prevailing seas
will be 2-4 ft near few days. Main concern for boaters the next
couple of days will be offshore moving showers and storms capable
of producing gusty winds, frequent lightning and reduced vsby in
heavy rainfall.

Rip Currents: Low to a marginal moderate risk of rip currents due
to weak swells the next couple of days.
