Discussion Updated for latest aviation discussion below.

Aviation Mostly clear skies and light winds prevail across deep
south texas this morning. Some passing high level clouds are
possible at times. Otherwise,VFR conditions expected for the next
24 hours. Light south-southeast winds will become moderate to
breezy by mid to late morning. Winds will gradually weaken by late
this evening into the overnight hours.

Prev discussion issued 405 am cdt Mon jul 23 2018
short term (today through Tuesday): strong 500 mb ridging centered
over new mexico will provide deep layer subsidence with the hottest
temperatures of the year across deep south texas for today. Record
to near record heat is expected today with high temperatures ranging
from the 90s to around 100 degrees across the eastern counties and
close to the coast to 105 and 110 degrees along and west of highway
281 i-69c corridor. The main concern today will be that higher dew
points near the coast that may not mix out sufficient to keep heat
indices below the 111 degree criteria. Confidence is not high enough
at this time to issue a heat advisory for this afternoon. However,
will issue a special weather statement for the elevated heat indices
and we will continue to monitor the heat index values through the
day. Mostly clear skies and lighter winds to allow for temperatures
will gradually fall to the mid to upper 70s overnight. Another hot
day is expected on Tuesday will very little change in the
forecast.

Long term (Tuesday night through Sunday): the large 500 mb
ridging that will be centered over the western half of the country
will start gradually shifting westwards later this week as 500 mb
troffing persists over the eastern half of the lower 48 states. As
the ridging retrogrades steadily westward expect a slgt break in
the afternoon sweltering heat that has plagued the region over the
last couple of weeks. Mean rh values remain pretty limited through
day 7 which will keep the conv potential down close to near zero.

However, enough humidity may edge into the region from the gulf
of mexico on Wed in order to justify some slgt chc of conv around
midweek mainly near the coastline. Otherwise will maintain only
some silent 10 % pops through next weekend.

The ECMWF max min temps in the longer range period are a little
warmer versus the GFS mex temps throughout the longer range
period. Will opt for a general 50 50 blend of the two longer range
model sets. Regardless of which model is used, temps will remain
above normal values throughout day 7.

Marine (now through Tuesday): surface high pressure across the gulf
of mexico and lower pressure inland will maintain light to moderate
south to southeast winds and moderate seas through Tuesday. Slightly
stronger winds will support small craft exercise caution conditions
on the laguna madre and the nearshore gulf waters this afternoon.

Tuesday night through Friday night: the pretty mild pgf will
prevail throughout the upcoming work week over the western gulf
and the lower tx coastline. This will maintain pretty low wind
and sea activity across the laguna madre and the lower tx gulf
waters. No SCA conditions expected through late fri.

Bro watches warnings advisories
Tx... None.

Gm... None.

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