area forecast discussion
national weather service tallahassee fl
147 am edt Sun jul 23 2017

Aviation [through 06z Monday]
Patchy fog and low clouds are expected to develop before daybreak
but any reductions in visibility or CIGS should be brief.

Scattered to numerous showers and thunderstorms will expand
inland from south to north across our area. As usual, any
visibility reductions due to showers storms will be brief.

Prev discussion [816 pm edt]
Near term [through tonight]
Convection is limited today primarily to the florida big bend and
panhandle. Though the sea breeze fronts are approaching the florida
border, satellite imagery show cumulus growth in SRN ga al has been
anemic and drier air aloft is likely having an inhibiting factor on
more widespread convective development. As a result, expect the best
rain chances through the early evening hours to remain in north
florida. After sunset, convection over land should rapidly diminish.

Model guidance is in excellent agreement for another round of
offshore convection developing after 06z Sunday across the marine
area and possibly spreading toward shore by daybreak, particularly
along the florida panhandle coast. Otherwise, should be mostly clear
well inland with temperatures inland in the low to mid 70s
overnight.

Short term [Sunday through Monday night]
The eastern CONUS trough will amplify slightly on Sunday, before
beginning to lift northeast on Monday. While the core of the
shortwave will move through the great lakes and the northeast, a
trailing ribbon of +pv will trail through the central plains and
eventually the mississippi valley. Locally, a flat east-west ridge
will prevail with afternoon storms generated by the seabreeze
fronts. With forecast westerly steering flow on Monday, expect
storms that generate just west of the tri-state region under broad
synoptic forcing to move into the region late in the day and mix
with seabreeze convection. High temperatures will be seasonable,
in the lower 90s with heat indices in the low 100's.

Long term [Tuesday through Saturday]
Lee cyclogenesis and the +pv ribbon moving over the appalachians
Tuesday through Wednesday will result in continued high pops.

Expect seabreeze convection in addition to storms dropping into
the region from the north that form closer to a surface low over
ga and sc. Later in the week, an eastern CONUS trough is forecast
to amplify again, increasing pops into the weekend. Highs will
continue to be near average.

Marine
Relatively light winds and low seas will prevail over the next
several days. Minor wind and chop enhancements near the coast in
the afternoon seabreeze will be possible each day. Showers and
thunderstorms will be most likely between midnight and noon.

Fire weather
No concerns.

Hydrology
A typical summertime scattering of storms is not expected to
produce any river flooding. Isolated minor flooding could be
possible in urban locations under slow moving storms.

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.
