Short term (today through Tuesday)
Temperatures will continue to moderate today with highs in the 70s.

High level cirrus is expected to move across the region today, but
still plenty of sunshine is in the forecast. Sfc winds will remain
light from the west and southwest today through tonight. Reinforcing
high pressure cold front is progged to push south across the area
by early Tue resulting in slightly cooler highs Tue afternoon as
well as a strengthening north wind. Winds across the gulf waters
are expected to become moderate with scec conditions. No precip is
anticipated with the surge of high pressure as the airmass
remains dry.

Long term (Tuesday night through Sunday)
The GFS and ECMWF deterministic runs generally consistent with the
development movement of an upper disturbance moving sewd across swrn
canada nwrn CONUS Wednesday, then across the plains ERN conus
Thursday Friday. The GFS deterministic predicts an increase in pwat
values to near normal over the ern CWA by Thursday afternoon. The
gfs deterministic predicts a persistent subtropical jet extending
from NRN cntrl mexico and across the gulf coast states from the
beginning of the period, with the CWA msa under the rrq of the
associated jet streak late Wednesday Thursday. Will forecast
isolated showers for the ern CWA msa Thursday afternoon. In response
to the foregoing upper disturbance, a front is predicted to enter
the CWA late Thursday (gfs ecwmf deterministic) and will likely
trigger additional isolated showers over the ern CWA msa. Drying
subsidence expected Thursday night Friday as the upper system and
associated cold front moves east. Anticipate at least scec
conditions over the msa Thursday night Friday after frontal passage.

The GFS ensemble mean suggests a more quasi-zonal upper pattern over
the CONUS Saturday Sunday and also predicts isentropic lift
Saturday Sunday over region, yet with low condensation pressure
deficits restricted mainly to the msa beginning Saturday night.

Anticipate patchy light rain isolated showers Saturday night Sunday
over the extreme ern CWA msa.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
