Near term [through tonight]
Showers and thunderstorms have developed across the florida
panhandle this afternoon and these storms will spread northward
through the remainder of the day. The highest pops into tonight will
be across the western half of the cwa, generally from tlh to aby and
west. Similar to yesterday, expect thunderstorms to persist well
into the evening and past sunset, later than the typical summertime
pattern. Lows will fall into the lower to mid 70s tonight.

Short term [Monday through Tuesday night]
A mid-upper level shortwave trough will swing into the southern ms
valley on Monday. Upper level divergence from this feature will help
develop a weak surface front out in the southern plains. Rich
moisture will remain on tap over the tri-state area ahead of this
developing system, with pw values hovering above 2". The combination
of the enhanced moisture, frontal forcing to our northwest, and a
little help from the seabreeze circulation is expected to give us
increased shower and thunderstorm activity for the next few days.

Locally heavy rainfall will be possible with these storms, along
with a low-end threat for strong to severe wind gusts (up to 50-60
mph). Highs will be in the upper 80s to low 90s and lows will be in
the low 70s.

Long term [Wednesday through Sunday]
The aforementioned front is expected to stall out to our south as
the upper level shortwave swings eastward. Behind it, however, more
shortwaves (further to the north) will eject into the longwave
trough, amplifying the pattern as we head into the weekend. This
will develop another surface front over the weekend, which will then
push into the southeast early next week. Highs will be mostly in the
upper 80s to low 90s and lows will be in the low-mid 70s.

Aviation
[through 18z Monday]
mainly MVFR toVFR conditions across the TAF sites this afternoon
but CIGS should continue to improve over the next few hours. In
addition, tsra will develop this afternoon and persist into at
least the first half of tonight. While all sites could see a
thunderstorm, the better chances will be across an area from tlh
to aby and west. Ifr CIGS are expected again Monday morning.

Marine
A weak frontal boundary will cross our coastal waters and then stall
to our south. Ahead of the front, south-southeasterly winds will
veer and become more westerly on Tuesday. On Wednesday, in the wake
of the front, they'll become northwesterly. Scattered to numerous
showers and thunderstorms are expected throughout the week.

Fire weather
There are no fire weather concerns for at least the next
several days.

Hydrology
There are no longer any local river sites in flood stage and levels
are either holding steady or continuing to fall. Scattered
thunderstorms over the next week will bring around 2-3" of rainfall
to the area, with isolated higher values. Widespread flooding is
not anticipated, but heavier showers could lead to localized
flooding.

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.

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.
