Update
For 00z aviation.

Short term

through tonight.

Upper level ridge axis from the west and slightly warmer upper
level temperatures have kept showers and storms isolated or
confined to the far southeast so far today. Heat indices at a few
locations in the northwest have warmed above 100-103f. With an
hour or so of additional warming and lack of convection in that
area, will maintain the heat advisory.

A weak shortwave remains across southeast alabama this afternoon,
aiding in thunderstorm coverage south of i-85. Expect most of the
activity to remain across the southeast through early evening, but
with colliding outflow boundaries, isolated to scattered coverage
is possible areawide. Rain chances diminish tonight. Another muggy
night expected with lows in the low to mid 70s.

Long term

Wednesday and Thursday.

By tomorrow, upper level ridging weakens slightly across the area
as does the weak shortwave. With similar upper level temps and no
real focus for convection, expect mainly scattered diurnal
activity and have lowered rain chances slightly. Although hot and
muggy, heat indices should remain below advisory criteria.

By Thursday, the upper level ridge strengthens across northeast
florida, extending westward across the deep south. Low level winds
across the area become southerly, bringing additional gulf
moisture northward. Pw values reach 2 inches by Thursday
afternoon. Upper level winds do remain cyclonic around the ridge
axis with no significant focus in the low levels. Will lower rain
chances to 40-50%, keeping activity scattered and mainly
diurnally driven.

Friday through Monday.

at the same time Thursday, guidance is developing an upper low
pressure over the southwestern gulf of mexico and dragging it
northward toward the texas louisiana coast by Friday. Thankfully,
at this time, there is no indication of any significant surface
feature to accompany it. That will be something that will bear
watching over the next couple of days.

By the weekend, guidance is in fair agreement bringing this upper
low around the ridge and onto the louisiana mississippi alabama
coast. This low should eventually get absorbed into the mean flow
across most of CONUS during Sunday. At the same time over the
weekend a surface front will be attempting to make progress
southward. The question is how much influence will the upper low's
timing have on the mean flow thus affecting the southward
progression of the surface front. This front should stall
somewhere across alabama Sunday into Monday. Regardless of where
the surface front stalls, we remain in an overall moist airmass
with rain chances continuing through the extended part of the
forecast thanks to the upper low then lingering trough across the
state.

00z TAF discussion.

Sct convection will continue thru 02z for areas north of i-85.

Earlier storms have stabilized air mass along and south of the
i-85 corridor, and no additional rain expected overnight for kmgm
or ktoi. Vcsh will at kbhm and keet, with vcts at kanb kasn ktcl
thru 02z. Fog will likely develop at ktcl and ktoi between 05z and
12z. Lifr conds likely at ktoi between 08z and 12z due to
prevailing rain that occurred Tuesday afternoon. Chance of diurnal
storms again on Wednesday and handled with prob30 groups.

Fire weather
Increased rain chances continue each day this week, with scattered
to numerous mainly afternoon showers and thunderstorms. Friday is
the best chance for more widespread rainfall. Localized fog is
possible each morning, but locations will vary depending on the
previous day's rain coverage. Temperatures will gradually return
to normal levels by mid week as relative humidity values continue
to rise.

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.
