area forecast discussion
national weather service houston galveston tx
401 am cdt Mon aug 26 2019

Discussion
- today we will have a heat advisory for this afternoon covering
all areas except the immediate coast. Hot conditions should
continue into Tuesday and may need to continue the heat
advisory.

- upper level ridge over texas through mid week might contract and
retrograde back to the desert sw. This might allow for a front
to move into the area for the end of the week weekend.

Short term [today and tonight]
After a period of inactivity earlier in the night, the radar is
again beginning to see the development of nocturnal gulf showers
over the waters just before 08z. It's a sign that the atmosphere
is trying to keep the typical late summer pattern going
- and with onshore flow and precipitable water just shy of two
inches, that's not a terribly big surprise. But now that we're
looking at rising heights and anticyclonic vorticity advection on
the back side of the merging gulf upper low northern stream upper
trough, I expect that we will be hard pressed to squeeze much more
than isolated showers and maybe a couple thunderstorms out of
today near the coast.

Instead, after days of focusing on rain potential, we quickly snap
back to our previous theme from this summer - heat. With ample low
level moisture in place, my forecast lows
are... Distressingly... Close to record warm minimum temperatures
for something like the millionth time this summer. While college
station and houston are already at their record and are probably
safe... Hobby and galveston have not yet cleared their records and
the cloud cover in place so far will keep temps from dropping
terribly quickly.

Of course, with the warm start, less rain, and clouds scattering
out through the day... Yup, you guessed it - heat advisory. The
bulk of the area was already in an advisory when I came in the
door. With only slight tweaks made, that advisory covers the
bulk of things, but did feel the need to add coastal jackson and
northern liberty as my area of hottest apparent temperatures was
ever so slightly larger.

Long term [Tuesday through Monday]
Overall we get stuck back into a hot stagnant weather pattern for
the middle of the week through the weekend. Other than some
subtle model differences in the strength and evolution of the
upper level ridge, model guidance remains on track from previous
forecasts. We might get a weak front into the area late
Tuesday Wednesday but that front look to stall more across the red
river area than anything else. Guidance has suggested that the
front could sag as far south as say lufkin to waco but will take
some strong convective cold pool re-enforcement to get the front
to push any farther south. Beyond that we get some return flow and
then another "front" over the weekend. Neither of these fronts
will be enough to "cool" the airmass at all but might be able to
get some "drier" air into the area. Its still summer so how the
air feels will be all relative to the recent hot conditions.

Marine
Stronger southerly winds are expected again tonight going into
Tuesday so we might need small craft exercise caution again. For
the rest of the week winds should remain around moderate levels
from the south with low seas. Winds might decrease more Wednesday
into Thursday as a weak front pushes near the area. Return flow
should set up on Friday.

Overpeck

Tropical
Ts dorian looks some better on IR satellite imagery this morning.

It has something resembling a central dense overcast but it is
still very small and compact. It is fighting some drier air around
it and this will likely hinder some development although shear is
low and ssts are high. Due to dorian being quite small and
compact, confidence in the track intensity beyond the first couple
of days is pretty low. As NHC notes in latest discussion, both
the GFS and ECMWF have dorian dissipating over the caribbean. At
this point, TS dorian will be something to monitor and nothing
more than that for now.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
