Discussion
The upper mid level ridge will continue to build into the
southeastern us and gulf of mexico through the rest of the
week, slowly moving into the western gulf of mexico during
the weekend and early next week. At the surface, the
subtropical ridge axis will gradually strengthen across
northern florida through the next few days, favoring
easterly flow. Low level wind speeds will become lighter
early next week as the surface ridge axis slides slowly
south into the florida peninsula.

Under strong subsidence from the stacked ridging, very warm
and stable conditions will hold through early next week,
with limited rain chances. Temperatures will run near record
levels, with afternoon highs in the low to mid 90s away
from the immediate coast through the next few days.

Temperatures will get even warmer during the weekend and
into early next week as the ridge gets even stronger
overhead, with highs in the upper 90s expected over the
interior. Morning lows will run from the mid 60s to mid 70s
during the next few days, then increase to low to upper 70s
by the end of the weekend and into early next week.

Aviation
Vfr conditions will hold through the next 24 hours.

Marine
Atlantic high pressure will continue to ridge into the
northeastern gulf of mexico through the rest of the week,
with generally easterly winds turning onshore near the coast
with the afternoon sea breeze. Nocturnal easterly surges
will bring wind speeds up to near cautionary levels each
evening. Rain chances will remain minimal through early next
week.

Fire weather
High than usual mixing heights will cause high afternoon
dispersion indices once again Thursday afternoon. Relative
humidity percentages will drop into the high 30s Friday
afternoon.

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.
