236 pm edt Wed apr 25 2018

Near term [through tonight]
An upper level low over the central plains will sweep southeast to
the lower mississippi valley by 12z Thursday. The associated cold
front will be pushing across central and southwest alabama at that
time. Ahead of the front, high pressure will remain in control of
our weather through the overnight with partly cloudy skies. After a
pleasant afternoon of temperatures in the upper 70s to around 80
degrees, overnight lows will drop in the mid to upper 50s inland,
with lower 60s near the coast.

Short term [Thursday through Friday night]
The upper level shortwave currently centered over kansas will
continue to quickly move southeastward, bringing a brief end to
quiet weather across portions of the tri-state region on Thursday.

Given the quick movement of this system and the likelihood of the
jet streak rounding the base of the trough and lifting the system
northeastward, rain chances will be confined to mainly our
alabama and georgia counties. Despite this, there will be a period
from mid to late Thursday afternoon where several strong storms
will be possible across southeastern alabama and
southwest southcentral georgia. Moisture will be sufficient, as
pwats are forecast to recover to 1.25 to 1.50" across these areas.

Uninhibited diabatic heating will allow for pockets of cape
ranging from 500 to perhaps as much as 1000 j kg as depicted by
some of the latest model guidance. This combined with 40 to 50 kts
of deep layer shear will support robust convection, with the
strongest storms capable of yielding damaging wind gusts. Given
last weekend's event, it is worth noting that shear profiles
across southeast alabama and southern georgia will likely be
unidirectional, which is not conducive for any rotating storms or
tornadoes.

This system will quickly clear the region late Thursday night early
Friday with another upper level shortwave trough on it's heels. This
feature will traverse the region Friday afternoon evening. However,
with mid level moisture largely being cleared out of the area by the
previous system, this feature will likely only yield cloudy
conditions across the region. Temperature wise, expect highs
ranging from the mid 70s to low 80s and lows in the mid 50s to low
60s.

Long term [Saturday through Wednesday]
A trough centered over the central great lakes will be ejected
eastward late this weekend, opening the door for deep layer ridging
across much of the eastern u.S. Through the end of the period. Dry
conditions are expected with temperatures gradually warming through
the period.

Aviation [through 18z Thursday]
Vfr conditions will prevail through the TAF cycle. Northwest winds
will become gusty this afternoon. Winds will drop off overnight
before becoming even gustier on Thursday. Scattered showers and
thunderstorms, some possibly strong will develop in this northwest
flow on Thursday. Most of this activity will hold off until after
this TAF period, but felt it was prudent to indicate the potential
impacts to the dhn and aby terminals as early as midday tomorrow.

Marine
Winds will generally range from 10 to 15 knots through the weekend
with resultant seas of 2 to 3 feet. Slight chance for showers
Thursday night into early Friday morning.

Fire weather
Aside from high dispersion values Thursday afternoon, there are no
other fire weather concerns.

Hydrology
Rainfall amounts with Thursday's system will generally be less
than a half of an inch and remain confined to a small area
northwest of a line from dothan through albany. Thereafter, no
rain is expected through early next week. Thus, flooding is not a
concern at this time.

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.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
