918 AM CDT Mon Jul 16 2018
.UPDATE...
Morning aircraft soundings out of Houston show strong subsidence 
above 950 MB. Expect today be dry and hot with highs in the upper 
80s along the coast to mid to upper 90s inland as a result. 
Saharan dust has also settled in and will result in hazy 
conditions across Southeast Texas today. Updated forecast for 
latest observations with no other changes made.

.PREV DISCUSSION... /ISSUED 400 AM CDT Mon Jul 16 2018/ 
DISCUSSION...
The GOES Total PW product shows values have dropped to ~1.2"
across the CWA. This along with increasing subsidence should keep
precip chances pretty close to zero today...and for the next week.
Other than adding the mention of haze to the forecast today, the 
rest of it was left virtually the same.
Upper level ridge will build in from the west throughout the week
bringing increasingly hot conditions to the region...with the hottest
days probably between Thurs-Sun. Though temperatures will likely 
be hotter well inland, it appears drier air mix down during the 
daytime hours keeping heat index values below the 108 degree heat
advisory threshold. What has happened in the past during similar 
patterns, however, is areas closer to the coast will get a 2-3 
hour spike of high heat indices once the seabreeze passes thru 
and dewpoints shoot up. It's still too early to say, but it's just
something to keep an eye on later this week. 47
MARINE...
Generally light S/SW winds will prevail the next several days as 
strong surface high pressure lingers over the north central Gulf. 
Shower/thunderstorm development expected to be very limited/zero 
through the remainder of this week as well. Low seas should also 
persist and no significant concerns are expected at this time.41 
AVIATION...
Brief/patchy fog will remain possible over inland areas this mor- 
ning...but the isolated showers over the coastal waters that have 
featured these past several morning are now absent. Slightly low- 
ered PWs and building high pressures over the Gulf should help to 
keep things quiet across SE TX for this afternoon. So will likely 
keep the mention of VCTS out...but may sneak in a mention of haze 
given the expected influx of Saharan dust. 41
