area forecast discussion
national weather service tallahassee fl
114 pm edt Fri oct 20 2017

Aviation [through 18z Saturday]
Vfr conditions will prevail through the evening. Some MVFR cigs
and vsby will develop in the predawn hours across our georgia
terminals. MVFR vsby could extend into al as well.

There is a vigorous smoke plume evident on satellite (and out our
window) just south of tlh. The plume extends to about 2500 feet.

Prevailing ene surface and transport winds should keep any vsby
restrictions away from the airport proper.

Prev discussion [943 am edt]
Near term [through today]
Deep layer ridging over the area will deliver another rain-free
day to the forecast area. Some clouds over the apalachee bay will
impact the coastal big bend. Otherwise, skies will be mostly
sunny. Look for afternoon highs in the lower 80s, expect for
portions of the big bend where mid 80s are expected.

Short term [tonight through Sunday]
A deep-layer ridge will be the dominant weather feature over much of
the eastern CONUS through Saturday. On Sunday this ridge will begin
to break down with the approach of an upper trough surface cold
front over the mississippi valley. Weak q-g ascent will begin across
northwest portions of our forecast area late Saturday, but very dry
air aloft and poor buoyancy will prevent significant cloud
development. This will begin to change by Sunday afternoon,
however, as deep southeast to south flow increases moisture
across our region, and q-g forcing continues to increase. Pops
will increase into the 20 to 30% range Sunday afternoon. Our
recent warming trend will continue through the weekend as
temperatures climb above average. Lows will be in the upper 50s
(north) to lower 60s (south) tonight, then in the mid to upper 60s
Saturday night. Highs will be in the mid 80s.

Long term [Sunday night through Friday]
There is good agreement among the latest global nwp models in
bringing a potent upper-level short wave trough through our
forecast area Monday and Monday night, followed by gradually
clearing skies and cooler temperatures on Tuesday. As if often the
case with these types of systems passing through our region in the
cool season, there are competing signals as to the potential for
severe thunderstorms. Relatively strong ascent and vertical wind
shear, as well as ample low-level moisture, would indicate at
least some threat of organized severe storms. On the other hand,
poor low-layer and mid-layer lapse rates suggest weaker updrafts
(less intense storms). Perhaps the threat will become more clear
in a few days when we begin to see some of the cam runs for that
period.

After the initial short wave trough passes, the eastern half of
the CONUS will be dominated by a mean, broad, upper trough for
the remainder of the work week. At the surface, a cool, dry
airmass will be in place across the southeast, and it will
actually begin to feel like fall by mid week as temperatures
gradually cool to below average levels.

Marine
A relatively strong high pressure system will remain centered
northeast of the marine area through Saturday night, maintaining
generally east winds in the 15 to 20 knot range and seas of 4 to
6 feet offshore. Winds will become southerly on Monday ahead of a
low pressure system, but winds and seas will remain elevated.

Fire weather
High dispersion values over 75 are possible today in big bend
florida. Otherwise no fire weather concerns.

Hydrology
Dry conditions will continue into the weekend. Widespread rain will
occur late Sunday through Monday night as a cold front move through
the area. Storm total QPF is generally 1 to 2 inches, but locally
higher amounts are possible. This is unlikely to cause widespread
flooding or have a major impact on river stages.

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.
