.AVIATION...
[Through 18Z Friday]

Low cigs are currently present across the region with vicinity
showers and thunderstorms. This will continue into the evening
with increasing cigs after sunset. Patchy fog may be possible
tomorrow morning impacting all terminals except ECP a few hours
before sunrise with cigs increasing a few hours after sunrise.

.PREV DISCUSSION [1045 AM EDT]...

.NEAR TERM [Through Tonight]...

A mid level trough remains overhead pumping in high PWAT moisture
content (2.1-2.2 inches) on southwesterly flow. Upstream, a
shortwave trough is noted in the Louisiana/Mississippi area and is
progged to move east through the day, arriving over our area this
afternoon. At the surface, a weak frontal boundary stretches near
the state lines of Florida and Alabama/Georgia.

Widespread cloud cover and low instability will once again be a
challenge for the forecast rain chances and temperatures. It is
possible to have some breaks in the clouds through the Florida Big
Bend, thus a little more instability to work with. Overall, kept
high rain chances today with showers and storms moving in from the
west, added mid level support from the approaching trough, and
the possible increase in stability in our southeast counties.
Chances will be in the 50-80% range, favoring our western areas
and Big Bend associated with the seabreeze. Locally heavy rainfall
is also a concern as the entire area is in a marginal risk for
excessive rainfall. Highs will be in the mid to upper 80s.

.SHORT TERM [Friday Through Saturday]...

A stationary boundary along the FL border has been keeping us in
a particularly wet pattern. This is still the case for Friday but,
upper level ridging will build in to our north through the short
term. This will allow the stationary boundary to move south
towards the gulf but, unfortunately we won't get the benefit of a
drier air mass moving in. We will still have ample moisture with
PWATs of 2" over the region. Showers and thunderstorms remain in
the forecast with the potential for heavy downpours and training
storms that could lead to localized flash flooding. PoPs for
Friday and Saturday range from around 80% on Friday and 70% on
Saturday. PoPs are higher for Friday due to a shortwave passing
around the larger upper-level trough that will provide extra
forcing for shower and thunderstorm development. Temperatures for
this period will be in the mid-upper 80s for the afternoon highs
and low 70s for the overnight lows.

.LONG TERM [Saturday Night Through Thursday]...

The upper-level ridging to our north will not be drying us out.
Showers and thunderstorms will remain in the forecast in a typical
summertime diurnal cycle for the long term. PWAT values will
continue the potential for heavy downpours that could lead to
flash flooding with any shower or thunderstorm. PoPs for the long
term range from 50-70% during the afternoons. Temperatures for the
long term will be in the upper 80s to low 90s for the Highs and
the Lows will be in the low 70s.

There are some global ensemble members and deterministic models
indicating the potential for a tropical disturbance/feature to
reach the western Caribbean by the end of the long term. As it
currently stands, the ridging that develops to our north should
help deflect any approaching disturbance to our west into the
western Gulf of Mexico, should anything materialize. That being
said, since we are approaching the climatological peak of the
season it is recommended to remain prepared as we continue to
monitor the tropics.

Now would be a good time to look over your hurricane preparedness
kits, be sure to check out www.weather.gov/safety/hurricane-plan
for valuable planning resources.

.MARINE...

Light and gentle breezes will prevail through Sunday, varying in
direction from northeast to southeast, as a weak bubble of high
pressure continues over the Southeast Coastal Plain. Showers and
thunderstorms can be expected each day, especially in the
overnight to morning hours.

.FIRE WEATHER...

Above average rain chances will continue for the next several
days. This, along with recent wetting rains, will keep fire
weather concerns to a minimum. The exception is afternoon low
dispersions which will continue into this weekend.

.HYDROLOGY...

No areal or river flooding is expected for the next 7 days. Any
thunderstorms of course are capable of producing heavy downpours
which can lead to short-lived drainage issues.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur (while following all local, state, and CDC guidelines) by
calling the office or tweeting us @NWSTallahassee.
