Marine Weather and Tides
Lower Grand Lagoon, FL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Update
Have already seen a few showers along the coast this morning and
will continue to see an increase late this morning into the
afternoon with scattered showers and thunderstorms expected. The
best coverage today will be across the florida panhandle (30%)
with pops decreasing inland. Have increased pops for the rest of
the morning across the florida panhandle based on latest radar
trends and also across the eastern portion of the CWA for this
tonight as a few storms may linger past 00z. Heat indices today
will be in the low 100s so for those spending time outside, make
sure to hydrate and seek shade.

Prev discussion [632 am edt]
Near term [through today]
Given the wet soils from last evening's thunderstorm over
tallahassee, light patchy fog will be possible by sunrise. Surface
high pressure will continue to build into the region today, with
moist southerly flow increasing over the florida panhandle. This
will yield slightly higher shower and thunderstorm coverage than
what has been observed the past several days as pw's gradually
increase today. Nonetheless, coverage will remain somewhat limited
today, with the highest chances remaining across north florida and
far southern georgia. Thunderstorms are expected to remain sub-
severe today. Afternoon highs will reach the mid to upper 90s.

Short term [tonight through Tuesday]
The local area will reside in a weak pressure pattern surface and
aloft. Time-height cross sections and forecast soundings show a
bit more moisture available for afternoon convection as pw's
continue to increase to around 2.0". Steering flow will be light
Monday so any convection that develops will be slow movers with
the most concentrated area possibly over the florida zones with
weak penetration of the sea breeze. On Tuesday, a weak front or
surface trough is forecast to drop down into south georgia which
will act as additional focus for showers and thunderstorms. It
will continue to be hot with highs in the mid to upper 90s and
heat indices in the 105 to 110 range both days. Lows will be in
the mid 70s.

Long term [Tuesday night through Sunday]
Typical summertime pattern with diurnal convection aided by the
sea breeze. Pops generally in the 50-60% range each day with
highs in the lower to mid 90s and lows in the lower to mid 70s.

Aviation [through 12z Monday]
Vfr conditions will resume everywhere between 14 and 15z and will persist
through the remainder of the period. Iso to sct shra tsra will
develop this afternoon across the region. However, coverage will
likely not be widespread enough to confidently include in taf
package. Westerly winds prevailing generally below 10 kts.

Marine
Light west to southwest winds with low seas will prevail through
the upcoming week.

Fire weather
Hazardous fire weather conditions are not expected through much of
the next week. Chances for wetting rains will become more widespread
from mid week onward.

Hydrology
A wet pattern will return next week. Local rivers are steady or
falling at this time. QPF over the next seven days is 1 to 2 inches.

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.

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.
