Vfr conditions areawide this morning although some patchy fog has
reduced vsbys at aex over the past hour or so. Klch radar shows
widely sctd -shra acrs coastal areas with activity dissipating
rather quickly as it moves inland. Convection expected to become
more sctd over inland areas as daytime heating gets underway over
the next few hours, with activity persisting and spreading
northward through the day. Inserted tempo groups for southern
terminals as shra tsra should be a little more widespread through
early mid aftn as it moves north. Outside of convection,VFR
expected to prevail, with southerly winds less than 10 kt. Showers
and storms should dissipate around or shortly after sunset.

Prev discussion issued 407 am cdt Sat aug 17 2019
discussion... Another warm and muggy night across the forecast
area. Satellite imagery showing some patchy and eroding mid-level
cloudiness left over from evening convection over the inland area.

Radar depicting an uptick in nocturnals over the near coastal
waters and immediate coast.

Moisture profiles across the area showing significant moisture in
place from the surface to 700 hpa with weak capping aloft. An
active sea breeze and easily attained convective temperatures
suggest scattered diurnal thunderstorm development on the horizon.

This includes the weekend and well into the coming week as the
pattern remains persistent. Hot and humid days, and warm and muggy
nights will continue.

Have held back on a heat advisory for today with the forecast
numbers falling slightly short of advisory criteria. If forecast
temps or dewpoints are underdone by just a degree or two, criteria
would be reached and day crew will accordingly issue advisory.

Marine... A ridge of high pressure extending across the gulf of
mexico will maintain a light and occasional moderate onshore flow
through the weekend and well into the new week. A daily chance
for showers and a few thunderstorms will continue, primarily
developing after midnight and continuing through the morning
hours. Rain chances will be highest over the eastern gulf waters
of the forecast area.

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.
