940 pm est Sat feb 17 2018

Near term [through tonight]
02 utc surface analysis shows a cold front across central alabama
and into north central georgia. Ahead of the frontal boundary
southwesterly flow is in place, keeping the local airmass humid
with dewpoints in the mid 60s, and some upper 60s near the coast.

With a similar set up to last night, expect another round of low
cloudiness and dense fog. Current 10.3-3.9 imagery shows an area
of fog stratus across the southeast florida big bend moving ne.

Over the next few hours hours, fog should spread further inland
and expansion of the dense fog advisory will likely be needed by
06z Sunday.

Prev discussion [703 pm est]
Short term [Sunday through Monday night]
The weak front will stall across our area Sunday and then lift
north as a warm front Sunday night into Monday. This boundary will
bring only a slight chance for showers, mainly over our northern
georgia zones on Sunday. Otherwise, it will be dry with above
seasonal temperatures. Highs will be in the upper 70s to low 80s
Sunday and the lower to mid 80s Monday. Lows will be in the upper
50s to low 60s.

Long term [Tuesday through Saturday]
The amplified trough over the western CONUS will slowly lift
northeastward through the week, allowing another cold front to
develop and approach our area by mid to late week. Deep layer
ridging centered just east of florida will hold and prevent the
front from reaching our cwa. However, deep southerly flow along
with warm temperatures will keep slight to low end chance pops in
the forecast for most of the upcoming week. Highs around 80 to the
lower 80s with lows around 60.

Aviation [through 00z Monday]
Vfr conditions currently prevail across our area with scattered
mid-level clouds under light southwesterly flow. However, areas of
fog are expected to move inland from the gulf later tonight,
starting at ecp and spreading inland overnight. Lifr visibility
and CIGS are possible, especially at ecp, tlh, and vld. Conditions
will gradually improve after sunrise, andVFR conditions will
prevail from noon through the remainder of the period.

Marine
Marine dense fog remains a problem over our eastern coastal waters
and a dense fog advisory is in effect through Sunday afternoon.

Otherwise, winds will be light to occasionally moderate though
the week.

Fire weather
No fire weather concerns are expected for the next several days.

Minimum rh values will remain well above critical thresholds, and
winds will remain light.

Hydrology
The choctawhatchee river at bruce will continue to gradually fall
through minor flood stage into next week. Spotty rain over the next
several days will have low accumulations (less than half an inch),
and is not expected to cause additional river flooding.

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.
