Update
No significant changes were made during the evening update.

Showers and thunderstorms have mostly diminished.

Aviation
[through 00z Thursday]
vfr conditions are expected this TAF cycle. Thunderstorms will be
isolated to scattered tomorrow afternoon with probabilities of 30
to 50 percent.

Prev discussion [214 pm edt]
Near term [through tonight]
Convection initiating along the gulf seabreeze as well as along a
surface trough through al and ga will continue moving northward
through the remainder of the afternoon. The greatest chance for
slower moving storms and the possibility of isolated flooding
issues would be in al and ga where steering currents are
converging. As is typical in the summertime, land-based storms
should come to an end within a few hours of sunset and then
transition to offshore late in the night.

Short term [Wednesday through Thursday night]
In the mid to upper levels, the western extension of the bermuda
ridge will gradually build further westward and extend across the
gomex. The surface ridge axis will remain over or just south of
our cwa. While the upper level ridging will bring warmer
temperatures and somewhat drier conditions to our area by
Thursday, there will continue to be ample moisture for diurnal
convection just not as widespread and heavy as we've seen the past
several days. Highs will be in the low 90s and lows will be in
the low 70s.

Long term [Friday through Tuesday]
Not much change in the overall pattern surface and aloft through the
extended period. Both the euro and GFS do hint at possibly a weak
surface low approaching and moving inland over the central gulf
coast around southeast la over the weekend. The models then spread
the moisture associated with this feature eastward which would bring
increasing rain chances beginning on Sunday. Highs will be around 90
to the lower 90 with lows in the low 90s and lows to mid 70s.

Marine
Winds and seas will remain low through the period outside of
thunderstorms, which will peak in the late night and early morning
hours.

Fire weather
Hazardous fire weather conditions are not expected over the next
several days.

Hydrology
A more typical threat of scattered summertime storms is expected
over the next week, with any sort of widespread flood threat
diminishing. However, both the econfina and steinhatchee rivers
remain in flood from the last week of heavy rain. The silver
lining is that both are cresting or have already crested, with a
gradual lowering of water levels over the next few days.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.

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.
