Aviation [through 12z Thursday]
Vfr through the period with light northwest winds.

Prev discussion [333 am est]
Near term [through today]
Surface high pressure centered over the southern plains will slide
east into the mississippi valley by this evening. Locally, a cooler
and much drier airmass will filter in on light northwest flow in the
wake of yesterday's cold front. Skies will be mostly sunny with only
high level cloudiness. Highs will be in the upper 50s to around
60.

Short term [tonight through Friday]
An upper level shortwave will move across the southeast tonight
with the only impact expected to be an increase in clouds. This
will quickly move east of the area with weak upper level ridging
moving in for the remainder of the week. High pressure will
dominate at the surface through the short term as a surface high
across the central CONUS moves to the east coast by Friday. The
short term will be dry with highs in the mid to upper 60s and lows
in the mid 30s, with the lower 40s along the coast.

Long term [Friday night through Wednesday]
A low will track across the southeast bringing precipitation back
to the area for the weekend. Guidance still shows some differences
with the track of the low with the ECMWF further north, moving the
low across the cwa, while the GFS keeps the low south in the gulf
of mexico. Regardless of the exact track, both will bring rain
back to the area. Have continued to confine the mention of
isolated thunderstorms to the marine area, however with a
northward track solution, thunderstorms could reach onshore.

Conditions will clear Sunday night, with a dry forecast for the
remainder of the long term.

Marine
Northerly winds will increase tonight with small craft advisory
conditions in the offshore waters beginning tonight. Winds will
remain elevated into the weekend. A low pressure system tracking
near the area will bring widespread showers and isolated
thunderstorms to the marine area for the weekend.

Fire weather
Minimum relative humidity values will drop near or below critical
levels across the tri-state region Thursday but light winds will
preclude any fire weather concerns.

Hydrology
The next chance of rain will be over the weekend with a low
pressure system bringing a widespread 1 to 2 inches to the tri-
state area. While this could cause some rises on local rivers,
flooding is not expected and overall the rain would be welcomed
given drought conditions.

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.
