401 pm cdt Fri aug 18 2017

Short term
No significant issues expected through the weekend with weak
surface high pressure in place along the coast with little
synoptic scale influences. Typical lake and gulf breeze boundary
convergence to be main focus of afternoon convection each day but
near climatological coverage. Temperatures, though warm to hot,
are also within a degree or two of normal each day. MAX heat
indices outside rain areas could still reach 105 for middle of the
afternoon.

Long term
Of particular interest will be viewing conditions for Monday's
total solar eclipse. At this time, still looking like 60% sky
cover and 35% chance for thunderstorms during the shadow window.

This is pretty much climo. Some marginal influence on temperatures
to flatten diurnal curve a bit during the early afternoon.

Tropical storm harvey will be in the process of moving through the
caribbean sea and across yucatan peninsula during the latter
portion of the forecast period. Little to no local affects
expected as long as the track remains in the lower bay of
campeche. Otherwise, barotropic air mass conditions to persist
with convection focused on gulf and lake breezes each day. 24 rr

Aviation
Vfr conditions should prevail at all of the terminals through the
forecast period. At kmcb, a weak inversion around 12z could result
in some patchy fog and reduced visibilities of around 3 miles. Any
fog should clear by 14z as the inversion mixes out. After 17z, some
scattered convection should develop and will have prob30 or vcts
wording in the forecast to reflect this risk. 32

Marine
A broad ridge of high pressure will remain in control of the
northern gulf of mexico through the middle of next week resulting in
fairly benign weather over the coastal waters. Variable winds of 5
to 10 knots and seas of 2 feet or less can be expected through the
period. 32

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.
