area forecast discussion
national weather service tallahassee fl
359 am edt Mon mar 27 2017

Near term [through today]
Upper level ridging will move east as a short wave translates from
the central plains to the ohio/tennessee valleys with the southward
extending trough just to our west by this evening. The associated
surface cold front will remain well to the west of the local region.

However, increasing instability along with warm temperatures and
increasing gulf moisture will be sufficient to generate isolated
showers/thunderstorms this afternoon, mainly along and north of
i-10. Temps will be in the mid 80s inland and upper 70s to around 80
along coastal areas.

Short term [tonight through Wednesday]
The aforementioned upper-level short wave trough will continue
translating east-northeastward tonight and Tuesday over the
eastern conus. A ridge will build in its wake over much of the
eastern CONUS on Wednesday. With minimal large scale forcing and
unimpressive amounts of deep-layer moisture, pops will be 20% or
less. High and low temperatures will generally be 5 to 10 degrees
above average for this time of year.

Long term [Wednesday night through Monday]
The large scale upper-tropospheric winds will be characterized by
a split-flow pattern over the conus, with the polar jet across
the northern tier of states and the southern stream across mexico
and the fl peninsula. A more active southern stream could help
benefit portions of our forecast area with better chances of
needed rain.

An upper-level cutoff low will lift slowly northeastward across
the ohio valley late in the week. The associated surface cold
front will move southeastward through our forecast area on Friday,
preceded by a good chance of rain (though pops will diminish from
west to east as the strongest ascent shifts north with time). The
gfs and cmc solutions suggest there will be enough vertical wind
shear and ascent for at least some storm organization (including
rotating updrafts) late Thursday night or early Friday, though
forecast MLCAPE values are below 500 j/kg and there may be
significant cin. The ECMWF upper level winds are less impressive,
suggesting less of a threat of severe storms.

Fair weather will return to our region next weekend as a deep-layer
ridge develops over the southeast. Rain chances will begin to
increase west to east at the beginning of next week. The airmass
behind Friday's cold front is unlikely to be significantly cooler
than the warm airmass it replaces, so we expect highs in the lower
to mid 80s, and lows in the mid 50s next weekend (as opposed to
highs in the mid to upper 80s and lows in the 60s Thursday).

Aviation [through 06z Tuesday]
As expected, fog and low level cloudiness is developing across
coastal and western portions of our region. Ifr/lifr conditions are
expected at all sites except vld by daybreak.VFR will return to all
terminals between 14-15z. Winds will be southerly between 10 and 15
kts today. There is a slight chance for an afternoon shower or tstm
at dhn, aby and vld but the chance is too low to include in tafs.

Marine
With a high pressure ridge across the coastal waters, low winds and
seas are likely through Wednesday. South winds and seas will
increase Thursday and Thursday night ahead of an approaching cold
front.

Fire weather
Aside from high dispersion today and dry conditions, there are no
other fire weather concerns.

Hydrology
Isolated showers or thunderstorms through mid week will have no
significant impact on the local river systems, which were well
below flood stage. Our current QPF for the cold front moving
through our forecast area late Thursday and early Friday ranges
from half an inch around dothan and destin to less than a tenth of
an inch around valdosta and cross city. However, ensemble output
from the GFS indicates that these forecast values may increase
with time, mainly from tallahassee north and westward.

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.
