Another weak low pressure center will then traverse the deep south on Sunday night and Monday, pushing the frontal boundary through the georgia waters on Monday morning before stalling over the northeast florida waters by Monday afternoon. This front will then lift northward through the georgia waters on Monday night as another low pressure center moves northeastward from the western gulf of mexico through the lower mississippi valley.

area forecast discussion
national weather service jacksonville fl
221 pm est Fri feb 15 2019

Short term through Monday ...

warm and moist southwest flow tonight will lead to patchy to areas
of fog advecting off the northeast gulf, and into NE fl. This fog
will then linger into the morning hours Saturday, before
dissipating.

A cold front will move into northern forecast area Saturday and
stall through the weekend into early Monday. Expect shower potential
to be confined to area along the boundary this weekend. The front
will sink south to near the ga fl line Monday afternoon with an
increase in shower chances.

Temperatures will be well above normal this weekend. Temperatures
will be above normal again Monday, but warmest will be south of the
front over NE fl.

Long term Monday night through Friday ...

a low will develop over the northwestern gulf Tuesday, helping to
lift the stalled boundary back to the north as a warm front. The
region will be in the warm sector largely south of this warm front
with a cold front west northwest through Friday. The warm front could
slide back south into forecast area at times next week, as waves
ride northeast along boundary. Therefore, can not rule precipitation
chances any day next week, especially SE ga.

Temperatures will be well above normal this period.

Marine
High pressure will be southeast of the region over the weekend with
a frontal boundary to the northwest. This boundary will sink south
across area waters Monday, then lift back to the north through the
week as high pressure builds to the east southeast.

Rip currents: low risk through Saturday.

Aviation
Vfr conditions will prevail at the regional terminals
through at least 06z, with broken high cloudiness
expected to continue through tonight. MVFR visibilities
will likely develop at vqq shortly after 06z, and ifr
conditions will then be possible towards 10z at gnv as
low stratus and fog advect northeastward from the gulf
of mexico. Low stratus ceilings will be possible at the
rest of the northeast florida terminals after 12z, but
confidence remains too low to include in the recent taf
package.VFR conditions should then prevail by 16z
Saturday, with broken ceilings of 4000-5000 feet expected
to develop. Southwesterly surface winds will increase to
near 10 knots at the regional terminals after 14z.

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.
