area forecast discussion
national weather service tallahassee fl
931 am edt Sat aug 18 2018

Update
Precipitation coverage continues to increase across the western
fl panhandle and will expand northeast this afternoon. Forecast
is on track with no major changes.

Prev discussion [644 am edt]
Near term [through today]
An upper level trough will persist over the area between a ridge
trying to build in from the west and the bermuda ridge to our east.

Global models show a southwest to northeast oriented deep plume of
moisture cutting through all but the southeast big bend of our cwa.

Forecast pw at tallahassee this afternoon is 2.2" compared to 1.7"
at cross city. This moisture combined with daytime heating and sea
breeze interaction will result in scattered to numerous showers and
thunderstorms. Pops today will be tapered highest(70%) west to
lowest (20-30%) across the southeast big bend.

Short term [tonight through Monday]
The general upper-level northern stream pattern will be driven by
a couple of shortwaves through early next week. The first will
move through the ohio valley and mid-atlantic Sunday through
Sunday night, with a brief period of ridging building in ahead of
the second wave forecast to be in the middle mississippi valley
towards the end of the period. At the same time, a tutt is
forecast to move over the florida straits and across the extreme
southern gomex. Favorable upper-level forcing on the NW quadrant
of the tutt, combined with deep layer southwesterly flow will
result in an early start to shower and thunderstorm activity,
becoming more widespread through the day. The most favorable
region for widespread and potentially heavy rain will be along and
northwest of a line from apalachicola through tifton. On Monday,
drier air will move in aloft, with deep layer ridging taking hold
in the wake of the northern stream trough and tutt. Expect a more
typical scattering of summertime seabreeze convection Monday.

Long term [Monday night through Saturday]
The shortwave in the middle mississippi valley will start the
anomalous amplification of the northern stream longwave trough,
with a couple more shortwaves superpositioning over the eastern
conus through the week. Tuesday's convection will likely still be
seabreeze driven, though mid to late week storms should be more
widespread associated with the northern stream trough and
associated cold front. It's unlikely we'll get a 'clean' frontal
passage, so wet conditions should be expected as the front will
likely stall and dissipate over the southeast.

Aviation [through 12z Sunday]
Brief period of MVFR CIGS vsbys at dhn and vld this morning.

Otherwise, showers and thunderstorms currently developing along
the panhandle coast and inland near ecp this morning will
gradually spread north and east through the day. Expect at least
brief impacts from storms with gusty winds and possible MVFR
vsbys cigs.

Marine
Seasonably low winds and seas are expected over the next several
days, but could increase as we near mid-week as a cold front
approaches.

Fire weather
Outside of possible low dispersions across portions of the florida
panhandle Sunday afternoon, hazardous fire weather conditions are
not expected.

Hydrology
In general, 1-2" of rain is forecast along and west of the
apalachicola and chattahoochee rivers over the next couple of days
and around 1" to the east. Isolated higher amounts are possible
especially through the weekend. Ensemble guidance for area rivers
suggests the potential for action stage along the most reactive
basins west of the aforementioned delineation. Scattered 'nuisance'
urban and rural flooding will also be possible through the next
week.

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.
