Coldest weather since mid-march across the region tonight...

Near term [through today]
Light to moderate rain will make a quick exit this morning as low
pressure moves away from the area and high pressure moves in with a
drier and cooler airmass. Despite clearing skies this afternoon,
cold air advection will keep high temperatures on the cool side,
ranging from the upper 40s across southeast alabama to the lower 60s
around cross city.

Short term [tonight through Saturday]
The coldest air mass of the season will descend upon the region
tonight into Friday morning. Low temperatures away from the gulf
coast will dip down into the low to mid-30s, 10 to 15 degrees
below normal. Those in hurricane impacted areas should check on
individuals that are in temporary housing, especially without
adequate heating. Vulnerable populations include the elderly and
infants, who are more prone to hypothermia. Check with local
officials on cold weather emergency shelters. In addition, make
sure any portable heating methods are properly ventilated, to
prevent carbon monoxide (co) poisoning.

High pressure settles into the lower mississippi valley tonight.

Aside from some high clouds mainly northwest of the big bend,
skies will be mostly clear. The surface pressure gradient relaxes,
but not entirely, so northwest winds will remain around 5 mph
or less. Given slightly elevated winds, owing to the surface high
being further west than the climatologically favored position
for a widespread frost, expecting patchy frost at this time.

However, if guidance trends cooler with temps and or lighter
with winds, then a frost advisory may eventually be needed for
portions of the area.

For Friday and Saturday, a zonal flow aloft with the column
remaining dry, as high pressure gradually shifts north into
the tennessee valley. Expect a few high or cumulus clouds,
otherwise mostly sunny and dry weather. Temperatures on a
moderating trend through the period. Highs around 60 Friday
and well into the 60s on Saturday. Lows around 40 Saturday
morning.

Long term [Saturday night through Thursday]
With the northern stream removed well to the north, and a zonal
west to northwest flow in the southern stream across the southeast
us downstream of a western CONUS ridge, a fairly tranquil period
of weather is in store. There is the potential for some increased
mid and high cloudiness at times during the early to middle part
of next week in association with fast moving shortwaves, but the
column remains dry, so no precip is expected. The surface flow
remains northerly with high pressure generally situated to the
north of the area and the air mass gradually modifying. Temps
will be in the upper 60s to lower 70s through the period, about
5 to 10 degrees below average.

Aviation
[through 06z Friday]
light to moderate rain with ifr ceilings will come to an end from
west to east this morning. Expect clearing skies with a return to
vfr conditions by afternoon.

Marine
A small craft advisory remains in effect for the waters 20 to
60 nautical miles offshore through this morning. For the near-
shore waters, a small craft exercise caution headline remains in
effect for today. Northerly winds will remain in the 15 to 20
knot range through Friday morning, mainly for the waters 20 to
60 nautical miles offshore. For this weekend into the middle of
next week, more tranquil boating conditions with northerly winds
generally 15 knots or less and seas at or below 3 feet.

Fire weather
Red flag conditions are not expected for the next several days.

Hydrology
Periods of rain will continue through this morning with
additional amounts up to one inch, the heaviest of which will be
across the eastern big bend and southwest ga, then dry weather
returning this afternoon through the rest of the period.

There are some river basins, especially across the fl panhandle,
that are in action stage with forecasts into flood such as the
chipola and apalachicola (the choctawhatchee near bruce is no longer
expected to reach flood stage). The kinchafoonee creek may also
reach flood stage over the next few days in southern georgia. In the
longer range, the flint river is expected to eventually rise into
action stage due to increasing flows from moderate to heavy rain in
central georgia.

please visit http: water.Weather.Gov ahps2 index.Php?wfo=tae.

Spotter information statement
Spotter activation is not requested. However, spotters are always

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.
