312 am edt Sat apr 21 2018

Near term [through today]
With a surface ridge to our north and a deepening area of low
pressure to our west, the area will be under strong easterly winds
today. This will bring a return flow of low level moisture from the
atlantic, brining in some low level clouds and slight chances for
rain today. Temperatures today will peak in the mid-upper 70s.

Short term [tonight through Monday]
In the upper levels a trough will move into the region Saturday
night. At the surface a low over the lower mississippi valley will
will produce showers and thunderstorms well ahead of the cold front.

Rain and or thunderstorms can be expected from Saturday night
through at least Monday. The best chance for rain will be Sunday
afternoon through Sunday night. There is a marginal threat for
severe weather on Sunday afternoon or Sunday night. The major models
are in disagreement on instability and deep layer shear values but
either way it looks like there will be some potential for a few
strong to severe storms to develop. Conditions may be favorable for
damaging winds. Skies will be mostly cloudy and highs will be in
the 70s. Lows will be in the lower 60s.

Long term [Monday night through Saturday]
In the upper levels a trough will be over the southeast with a few
major shortwaves moving through the pattern this week. At the
surface a low will be over the southeast this week. A cold front
will move through on Monday and another one is likely on Thursday.

Highs will be in the 70s and lows will be in the 50s.

Aviation [through 06z Sunday]
MVFR CIGS will move in from the southwest this morning into north fl
and south-central ga. Winds from the east will occasionally gust too
15 to 20 knots during the daytime hours and will remain moderate,
around 10 knots, overnight ahead of an approaching front.

Marine
Strong easterly winds will decrease and become southerly on 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
Transport and 20 foot winds will be elevated for the next few days
as a cold front moves across the southern u.S. Relative humidity and
other variables will not reach our other red flag thresholds,
however, so no red flag conditions are expected.

Chances for showers and thunderstorms return today and could last
into Tuesday.

Hydrology
Most local rivers are currently below action stage. Rain is expected
Saturday night through Monday. Rain will be moderate to heavy at
times. 2 to 3 inches of rain is forecast for most locations with
higher totals possible particularly in SE alabama and SW georgia.

The typical flooding of low lying areas and ponding of water on
roadways can be expected. Flash flooding cannot be ruled out
completely 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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
