national weather service jacksonville fl
946 am edt Thu jun 20 2019

Breezy and muggy with morning rain across NE fl then severe
threat across SE ga late afternoon early evening...

Update
Synopsis... Localized flooding potential mainly along and south of
the i-10 corridor this morning with a few rotating cells gusty
winds, then transition to severe storm focus across SE ga near the
altamaha river basin late afternoon into the evening. Muggy and
breezy even outside of rainfall today, gusts up to 30 mph at
times.

Change in weather ingredients across the local area today with
increased shear thanks to a low level 925-850 mb jet near 35-45
kts out of wsw streaming over the local area this morning, but
with less deep layer moisture in place (precipitable water down to
1.78 inches this morning compared to 2.20" yesterday morning per
jax 12z raob). A very saturated low low level airmass remained in
place, however, with surface dew pts in the mid to upper 70s
across the entire forecast area this morning under moist wsw flow
out of the gomex below 770 mb. A low level boundary extended w-e
across north florida, with speed shear and convergence triggering
early start to convective growth edging inland from the gomex.

Through mid-afternoon, best chances of training rainfall which
could could cause localized flooding issues will continue to
focus across the suwannee river valley under ideal moisture
transport from the gomex. In addition to the minor flood concern,
elevated low level helicity values (~150 m2 s2) will produce some
shallow rotation this morning across the suwannee river valley,
with a low potential for a weak, brief tornado, but weak mid level
lapse rates do not support significant stretching.

Expect additional bands of showers developing and moving quickly
east ward on either side of the meandering boundary through mid
afternoon.

Into the mid-late afternoon, the boundary will settle farther
south with a gradual decrease in both convective coverage and
intensity across NE fl as dynamical forcing weakens, while an
increase in thunderstorm potential is expected across our northern
ga zones as a squall line organizes north of the local area
associated with strong upper level dynamical support. Shear will
increase as temps to rise into the lower 90s combined with dew
pts in the the low mid 70s creating very high surface based
instability. Thus, convective ingredients for severe storms
expected to phase with the potential for a couple waves of severe
storms edging ese across our ga zones late afternoon into the
evening. Main hazards will be downburst winds and large hail,
with a lower potential for isolated tornado.

Strong low level winds will mix down to the surface in cloud
breaks today with gusts up to 30 mph outside of shower activity.

Gusty to near 35-40 mph will be possible in just shower given
strong low level jet this morning.

Temperatures will remain in the low mid 80s across suwannee river
valley due to morning clouds, with highest temperatures in the low
90s focus across inland SE ga and toward the atlantic coast where
a sea breeze is not expected to move inland due to strong wsw
flow.

Aviation
Ifr to MVFR stratus will gradually break up through late morning
and lift to MVFRVFR cumulus deck. As stratus breaks, will see an
increase in wsw winds with gusts to 22-26 kts given strong low
level winds of near 35 kts at 2 kft. This wind maxima will gradually
decrease into the afternoon. Restrictions in passing showers and
tstorms expected, with rain chances advertised at all fl terminals
late morning through evening. Ssi rain chances not introduced until
late afternoon, although a rogue shower may near the terminal. Evening
rainfall potential generally fades by midnight, although low chance
of morning rainfall will exist across NE fl as well as stratus which
could again cause restrictions.

Marine
Advisory conditions gradually fading over the outer waters as buoy
41008 grays reef was down from sustained 21 kts at 5 am to 19 kts
at 830 am edt. Combined seas were 4-5 ft at grays reef to 3 ft at
near shore buoys 41112 and 41117. Into the afternoon, a brief
decrease in wind speeds expected as winds back ssw with a decrease
to 15-20 kts with exercise caution conditions anticipated, thus
the current advisory is expected to be able to drop at 10 am edt
this morning. A return to advisory conditions expected tonight as
low pressure tracks nne of the local waters.

Rip currents: low risk under breezy offshore flow.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
