area forecast discussion
national weather service tallahassee fl
129 am edt Sun apr 22 2018

Aviation [through 06z Monday]
Strong easterly winds will become southeasterly this afternoon as
a cold front pushes toward the area. MVFR CIGS are mostly
affecting our southeast al sites at the moment, but are expected
to develop across the region through the period and may drop to
ifr near ecp and dhn around sunrise. Conditions may deteriorate
further late this morning and this afternoon as storms move into
the area ahead of the front.

Prev discussion [841 pm edt]
Near term [through tonight]
Low-level easterly flow will continue across the region overnight
under the influence of strong surface high pressure parked over the
mid-atlantic and new england. Upper low currently over the high
plains will gradually shift westward into arkansas overnight.

Onshore flow above the boundary layer will increase across the local
area as a result, providing enough lift for scattered showers to
develop after midnight. Rainfall amounts should be light with this
activity. Expect low temperatures in the lower to mid 60s
overnight.

Short term [Sunday through Monday night]
Quiet weather will come to an end on Sunday as an upper level low
and associated surface front move into the region. At the beginning
of the period, showers and thunderstorms will be ongoing across
eastern portions of the lower mississippi valley and southeast. This
activity will move into the tri-state region late Sunday
afternoon early Sunday evening and is expected to persist through
Monday morning before conditions gradually improve from west to
east. The main threat from this system will be heavy rainfall, with
forecast rainfall totals of 2 to 4 inches generally west of the
apalachicola chattahoochee rivers and 1 to 2 inches east. Though
heavy rain will be the main threat, deep layer shear on the order
of 40+ knots and CAPE in the range of 500 to 1000 j kg will yield
an environment capable of supporting isolated strong to severe
thunderstorms, particularly on Sunday evening. It is noteworthy
that low level directional shear looks fairly substantial in the
current model guidance, and storm mode will likely consist of
broken cell clusters semi-discreet cells. An isolated tornado is
not out of the question in this kind of environment. Isolated
instances of damaging wind gusts are possible, especially with any
cell to cell, cell to cluster mergers that may occur. Seasonal
temperatures will persist through the period.

Long term [Tuesday through Saturday]
The upper low that will be responsible for Sunday and Monday's
showers and thunderstorms will slowly lift poleward on Tuesday
before getting kicked eastward by an approaching clipper system from
the west Tuesday night Wednesday morning. Model guidance remains
consistent this afternoon in depicting some wrap around moisture
yielding showers across southeast alabama southern georgia on
Tuesday. Quiet weather will be short-lived on Wednesday, as a quick
moving shortwave trough will bring another chance of showers to the
region late Wednesday early Thursday time-frame. After this system,
model guidance diverges significantly moving into the weekend, thus
pops for Friday and Saturday are low confidence at this point.

Temperatures will remain seasonal through the period.

Marine
Elevated easterly winds will continue to yield advisory level
conditions across coastal waters through Sunday afternoon. A small
craft advisory remains in effect until Sunday afternoon. Showers and
thunderstorms are likely Sunday through Monday as a cold front
approaches.

Fire weather
While winds will be elevated over the next few days, rh values
will preclude red flag warnings. Widespread showers and thunderstorms
are expected Sunday into Monday.

Hydrology
All river points are below action stage this afternoon. Rainfall
totals of 2 to 4 inches can be expected west of the
apalachicola chatahoochee rivers Sunday through Monday, with general
amounts of 1 to 2 inches east. Rainfall will be heavy at times,
likely causing minor flooding issues in urban and poor drainage
areas. Instances of flash flooding cannot be ruled out at this time,
given the rainfall rates that will be possible with some of this
activity.

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.
