Aviation
[through 12z Saturday]
ridge of high pressure will be situated across the southeast third
of the CWA into the northern gulf. This will act to suppress much
of the convection today with isolated coverage. Out west the
effects of the ridge will not be as strong and widely scattered
coverage is possible. Winds will be light this morning becoming
southerly later this morning.VFR outside of convection.

Prev discussion [349 am edt]
Near term [through today]
Upper ridging is present in the gulf and western atlantic with
southerly low-level flow toward the western fl panhandle. Dry air
aloft and subsidence in the eastern portion of our CWA should keep
pops low in the big bend. Best chance for showers and thunderstorms
will be in the western panhandle and southern al via seabreeze-
driven convection. Highs will be in the low-to-mid 90s.

Short term [tonight through Sunday]
Pwats increase through the short term as a tropical wave moves
near florida and a weak frontal boundary sags southward. This will
cause the mid level ridge to weaken and retreat as a shortwave
trough moves through the central plains. This will help deepen the
northeast long wave trough and aid in pushing the front
southward. The combination of these features will add the
convergence needed for scattered to locally numerous thunderstorms
especially into Sunday where likely pops are advertised. Highs
will be in the low to mid 90s Saturday with upper 80s to around 90
degrees Sunday with added cloud cover and rainfall.

Long term [Sunday night through Friday]
High atmospheric moisture will be the story next week with pwat
values in excess of two inches through the period. Storm coverage
early in the week will mainly be diurnal sea breeze driven and given
the degree of moisture expect pretty good coverage over the inland
areas along with locally very heavy rainfall. Later in the
period... Wed thu... Heights fall as a trough digs into the eastern
conus and a weakening cold front tries to make a run at the region.

The front won't make it but another surge of moisture will keep the
threat for convection going. Temperatures will remain around
seasonal normals throughout the week.

Marine
Light winds and low seas will prevail into next week, with an
uptick in rain chances starting late in the weekend.

Fire weather
A wet pattern will return this weekend and linger through next
week. Patchy fog is possible in the early morning hours. Otherwise
no fire weather concerns.

Hydrology
Just isolated storms are expected through Saturday which will allow
elevated rivers over the eastern big bend to continue to subside.

Shower and thunderstorm coverage will increase early next week as
deep tropical moisture returns. Locally heavy rains are likely each
day next week but widespread flooding is not anticipated at this
time.

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.
