.AVIATION...

MVFR conditions at ALI for vsbys and LRD for ceilings will
continue for another hour or two. IFR/MVFR conditions at VCT will
persist through 13z as well. VFR conditions will return by mid
morning at all terminals. Winds will increase by midday with some
gusts between 18 and 22 knots during the afternoon at ALI/CRP/VCT
but will remain elevated at LRD through the evening. Some sporadic
MVFR cigs/vsbys may occur late in the period at ALI/VCT again and
have included tempo groups to account for this.

.PREVIOUS DISCUSSION... /Issued 357 AM CDT Sat Jul 21 2018/ 

SHORT TERM (Today through Sunday)...

A persistent weather pattern will continue across South Texas 
this weekend. Upper level ridge remains anchored across the Four 
Corners region southeastward across the state. This will result 
in little relief from the heat and humidity during the short term.
Temperatures today will range from 106-107 degrees near the
international border to around 100 degrees at Victoria. Across the
Coastal Plains, highs in the middle to upper 90s can be expected.
For the southern Coastal Bend, heat index values will be the
highest...between 110 and 114 degrees this afternoon. A heat
advisory was issued for inland and coastal Nueces and Kleberg
counties. For the remainder of the area, a special weather
statement will be issued for heat index values between 105 
and 109 degrees. 

Similar conditions are expected on Sunday. Highs may actually be a
degree or two warmer in most locations. Dangerous heat index 
values will occur again tomorrow afternoon. 

LONG TERM (Sunday Night Through Friday)...

The mid-level ridge begins to retrograde back to the northwest 
allowing for a mid-level trough of low pressure to slide south 
across the eastern US Monday into the northeastern Gulf. As this 
trough slides south, surface low pressure across the Ohio Valley 
will also be able to slide south into the SE US bringing its 
associated weak frontal boundary. Moisture is expected to increase 
with the trough/frontal boundary toward the mid-to-late week across 
the Gulf and the Coastal Plains/Victoria Crossroads. The capping 
remains rather strong which may inhibit rain activity, but it is 
slightly weaker with H85 temps around 18-20C across the coastal 
region so will continue a slight chance for showers and 
thunderstorms. Overall, temperatures will still run hot with mid to 
upper 90s across the coastal region to near 110 toward the Rio 
Grande Plains early in the week. Temperatures should cool a few 
degrees for the latter half of the week due to the increase in 
moisture. Heat index values of 105-109F are expected for much of the 
area early in the week, but will become more focused to the southern 
Coastal Bend and Brush Country for the latter half of the week.
