Aviation
Ifr MVFR stratus evident on split channel satellite imagery this
morning may impact all terminals through 13-14z except lbx and gls
based on latest trends. Heating later this morning will allow
ceilings to lift and scatter, but may result in a secondary round
of brief MVFR at lbx as cumulus build along the sea breeze.

Otherwise,VFR is expected to prevail by mid to late morning.

Another round of ifr MVFR stratus will be possible again Monday
morning. South to southwest winds are expected to remain between
5-10 knots through the period.

discussion...

patchy fog this morning over the southwestern counties should be
short lived after the Sun comes up. Yesterday was hot with
numerous sites reporting 108 heat index and that was with cirrus
that helped to keep temperatures down below the forecast highs.

Today the cirrus has departed and skies should be mostly sunny to
sunny by 9 am. Some cirrus will probably move into the area this
afternoon but not nearly as widespread nor as thick. Winds will
again start out west- southwesterly peaking in the morning then
becoming more southwest and even south by late afternoon.

Soundings indicate a little more moisture is present today and
that mixing will still occur but will likely not be as dry as
yesterday. This should yield higher heat index readings today than
yesterday. Will continue the heat advisory and given that
temperatures will probably even warmer Monday with nearly the same
moisture heat advisory criteria should be reached again with 108
or greater popping up throughout the afternoon. Sharp ridge axis
over the area will finally rotate southwestward and flow aloft
will become more northerly late Monday. A S W is progged to drop
into the area Tuesday along with a weak frontal boundary and
could spark a few showers and thunderstorms but will bring cloud
cover. This should lead to lower afternoon temperatures and heat
index readings closer to 105 Tuesday. The front washes out over
the area Wednesday with moisture pooled over the area. Subsidence
returns and could see capping develop lessening the rain chances
at least over the north. A jumbled wind pattern ensues wed-fri
dominated by the seabreeze and low level ridging. Temperatures
should warm up Wednesday through Friday and will remain well above
normal.

Record high minimum temperature at iah is possible today - 80 is
the record set back in 1995.

A large plume of saharan dust currently over the eastern caribbean
will move into the gulf and could get carried into setx on
Wednesday... Possibly more concentrated in the southwestern
counties. Plenty of time to refine that forecast in the coming
days.

marine...

surface high pressure over the southern gulf will keep south to
southwest winds in place through Tuesday morning. Winds may briefly
strengthen into the 15-20 knot range tonight as this surface high
wobbles northward, strengthening the surface pressure gradient, and
caution flags may be needed. A weak cold front approaching the
waters during the day Tuesday may bring a few showers and storms as
well as a light variable to light offshore flow during the mid-week
period. Light onshore flow looks to resume by late in the week.

Huffman
fire...

little change in overall conditions are expected today and tomorrow
with minimum relative humidities falling into the 25-35 percent
range during the afternoon hours. However, light winds will limit
overall fire weather threats during this time. The texas a&m
dispatch tracker reported one fire yesterday in houston county and
hot and dry conditions will continue to aid isolated fire starts as
finer fuels cure further.

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.
