Update
A much quieter evening than 24 hours ago... Clear inland skies to
partly cloudy along the coastline. This morning's front stalled
along the coast with drier air slowly filtering into the region

Lower 50 dew points into the city with coastal lower 70 tds.

As southwesterly coastal breezes back more southerly... Per the
washing out of the remnants of today's frontal boundary... Southern
county middle to upper 60 dew points will creep further inland.

This will create lower dew point depressions as ambient coastal
/central interior county evening temperatures in the upper 60s to
lower 70s fall into the low to mid 60s past midnight. This will
produce an environment conducive to fog development... Possibly
more dense over those areas that received higher fri-sat rainfall
and still have moist grasses or soils. Slow post-sunrise improvement
to a stratus deck tomorrow morning... Scattering out to partly
cloudy by early afternoon. A shortwave upper trough passing into
the central plains tomorrow will lower inland pressures enough to
generate a tight onshore pressure and produce moderate daytime
southerlies. This stout onshore flow will advect ample moisture
inland... Equating to a partially cloudy afternoon with maxts in
the near 10 degree above normal inland middle 80s/coastal lower
80s. 31

aviation...

quiet evening expected, but expect some areas of fog to begin
developing south of i-10 and west of i-45 later. This should
gradually expand further inland overnight and toward sunrise with
mclr skies, light winds and wet ground in place. Most guidance
showing the bulk of more significant fog remaining mostly west of
i-45, then burning off by mid morning with a transition to a few
hours of MVFR cigs. CIGS continue to lift but pressure gradient
tightens up late morning and during the afternoon on Sunday.

Would look for some southerly wind gusts >20kt during this time
period. 47

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.
