Near term [through tonight]
Weak area of low pressure has moved from near panama city this
morning to near lake seminole this afternoon. Showers and
thunderstorms continue to develop in the vicinity of the low and
points eastward. With the moist southwesterly fetch continuing into
the big bend overnight, the potential still exists for additional
flooding. While rainfall amounts in southern taylor and dixie
counties have been modest so far today, even a brief period of heavy
rain could result in additional flooding. Will keep the current
flood watch as through the overnight hours. Farther north and
west, the bands of rain have remained progressive enough to
prevent any widespread flooding. However, any bands that do become
slow-moving could produce localized flooding.

Short term [Monday through Tuesday night]
A narrow upper level trough will remain sandwiched over our area
between the bermuda ridge and a ridge centered over the southern
plains. Deep layer moisture will accompany this feature. At the
surface, a weak trough will continue to meander over or just north
of our cwa. This along with pw values remaining above 2.0"
through the period, we can expect widespread rains with
thunderstorms each day. Some of the rain will be heavy at times
with rainfall rates exceeding 4" per hour. The flash flood watch
for the southeast big bend may need to be extended and possibly
expanded to encompass more zones. With the extensive cloud cover
and rains, MAX temps will be held down into the lid to upper 80s.

Lows will be in the lower 70s.

Long term [Wednesday through Sunday]
The narrow upper level trough will move off to the northeast by
Wednesday night, but is forecast to be replaced by a broader
trough toward the end of the week into the next weekend. In
addition to this upper level enhancement, pw values will remain
around 2 inches across the area through the weekend. As a result,
we will continue to see above normal chances for showers and
thunderstorms each day. Highs will be in the upper 80s to low 90s
with morning lows in the low 70s.

Aviation
[through 18z Monday]
showers and thunderstorms will impact ktlh, kvld, and kaby
through the remainder of the afternoon with reduced visibility and
lowered cigs. Showers should become less numerous overnight.

However, CIGS are also expected to drop to ifr levels overnight
before recovering by mid-morning on Monday.

Marine
Advisory level conditions will continue until late this evening,
diminishing to 15 knots though the remainder of tonight.

Thereafter, light to occasionally moderate winds with seas 3 feet
or less through the remainder of the week.

Fire weather
Low dispersions below 20 are possible tomorrow afternoon in SE al
and the fl panhandle. Patchy fog is likely in the overnight and
morning hours. The wet pattern will continue this week.

Hydrology
A flood watch remains in effect for dixie, taylor, and lafayette
counties through tonight. The storm total rainfall via radar
estimates and rain gauges shows a swath of 12 to 20 inches of rain
with locally higher amounts has fallen since Thursday along the
dixie and southeast taylor county coasts. The highest measured
rainfall total so far has been in steinhatchee where 29.54 inches
of rain has fallen in the three day period between Thursday and
Saturday, including 16.74 inches on Saturday alone. Significant
flooding exists in steinhatchee. In addition, while the heaviest
rain fell in the lower part of steinhatchee river basin south of
the steinhatchee river gauge, there was still enough rain at and
north of the gauge for it to reach minor flood stage. Future river
fluctuations will depend heavily on whether any additional
localized rain bands move over the basin.

The forecast additional rainfall from the wpc for the southeast big
bend is for an additional 1 to 4 inches of rain through Monday
with locally higher amounts possible. Elsewhere, 3 to 6 inches of
rain is possible along the panhandle coast with lesser amounts
inland. Some localized flooding could occur across portions of the
florida panhandle, but it has been drier in this area in recent
days. Convective trends will be monitored closely today to
determine if the flood watch needs to be expanded westward.

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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
