through tonight.

With increased moisture and a weak shortwave over the area,
storm coverage has been higher this afternoon than this past
weekend. While the added cloud cover and rain kept temperatures
and heat indices in check at some locations, heat indices have
reached over 105f in others. At 3pm, many locations are reporting
heat indices above 100f.

Main area of convection will be across the west and extreme
northeast for the next couple hours, as activity is becoming
mainly outflow driven. Coverage will decrease this evening, but
will need to watch clusters of storms in northern georgia and
southwest georgia as they move to the southwest and west this
evening. Expect all activity to diminish late tonight, with lows
in the low to mid 70s.

Long term

Tuesday through Sunday.

Much of the extended forecast remains on track for this update. On
Tuesday, high pressure sits over the eastern plains while a large
anticyclone remains over the western atlantic. In between these two
circulations, a weak low-level inverted trough and low height center
will situate over portions of the southeast including southern
georgia and the florida panhandle as southeasterly anticyclonic flow
aloft shifts the disturbance slowly westward over the forecast area
through Wednesday. This feature will provide support for afternoon
convection as we begin to see lower temperatures with highs
decreasing into the low to mid 90s, although higher humidity levels
will make it feel a bit warmer. The overall wind and height fields
become rather messy on Thursday with the aforementioned weak
troughing becoming much less defined, but with the bermuda high
extending to our southeast, a few periods of southerly low-level
winds appear likely enough to continue fueling a moist airmass
such that scattered to numerous afternoon thunderstorms can be
expected during peak heating on Thursday and Friday.

Meanwhile, deep-layer troughing deepens over the eastern CONUS by
the end of the week driving a cold front south through the ohio and
tennessee valleys. Uncertainty remains between model guidance on
whether the tail edge of the front will ultimately pass through the
forecast area this weekend, and confidence remains low on any one
given outcome. Therefore, the forecast for Saturday and Sunday, and
associated 50 to 60 percent pops, will be focused on the broad
cyclonic flow aloft over central alabama as the base of the trough
moves through the southeast in conjunction with a rich axis of
moisture (pwats ~2 inches) ahead of the front. Periods of rain over
the next week will help keep us cooler during the daytime with
highs in the upper 80s to near 90f Saturday and Sunday as ridging
becomes less pronounced over the forecast area.

Aviation
18z TAF discussion.

Afternoon convection will be biggest forecast challenge for this
taf period.VFR conditions & variable winds at 5-7 kts should
continue outside tsra activity, which may impact most if not all
terminals at some point today. Best chances reside this afternoon
& have handled with tempo groups generally after ~20z. Though
scattered shra & tsra will likely continue into the evening,
expecting decreasing coverage & intensity after dark. Have
included MVFR vis at eet toi towards 10-12z tomorrow morning,
especially since rain-cooled air may be in place overnight. Will
watch trends for MVFR conditions at other terminals, as well as
monitor obs for any needed amendments due to tsra activity this
afternoon.

Fire weather
Increased rain chances continue each day this week, with scattered
to numerous mainly afternoon showers and thunderstorms. 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.
