Update
Surface high pressure remains well north of the area this
evening with light northeast to east wind flow in place. Dry
sensible weather to continue overnight and into the day
Saturday. Only concern for the overnight will be the
potential for patchy fog. Latest model guidance suggests
best potential will be across the nature coast. Current
forecast has an excellent handle on this and no changes
needed to the ongoing forecast. Comfortable seasonal temps
continue tonight and into Saturday with low temps in the
low 50s to lower 60s.

Aviation
MainlyVFR conditions expected to continue tonight into
Saturday evening. May see some patchy fog overnight in the
normally vulnerable terminals of lal and pgd. Light
easterly winds overnight will become more westerly Saturday
afternoon less than 10 kts.

Marine
Weak high pressure and relaxed gradient for light winds and slight
seas through Saturday. A cold front will quickly move through the e
gulf Sunday with increasing NW winds and seas as a strong canadian
high pressure area builds into the region producing scec to sca
conditions late Sunday, Sunday night and into Monday. That high
pressure area quickly moves into the W atlantic into Tuesday ahead
of next week's gulf storm system.

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.
