.UPDATE...
A complex of showers and storms continues to push east near the Rio
Grande and is beginning to impact our western Counties. This complex
should maintain itself for awhile and have increased PoPs in this
region. The environment will support some severe weather as well
with damaging winds and severe hail. Updated products have been sent.

UPDATE...
See below for the 00z aviation discussion...

AVIATION...
Currently VFR at all terminals, with breezy southeasterly winds
continuing at AUS/SAT/SSF. Storms west of DRT may drift eastward
toward DRT later this evening, so have maintained VCTS at DRT from 2z
this evening through 6z early Saturday morning. Otherwise, generally
a repeat of the previous two nights is in store. MVFR CIGs are
expected to develop at AUS/SAT/SSF around midnight tonight, with DRT
joining the MVFR party by around 11z Saturday morning. CIGs should
improve to VFR around noon on Saturday. Southeasterly winds will
remain elevated overnight, with gusts up to 25 knots returning by
late Saturday morning and continuing through the afternoon hours.

PREV DISCUSSION... /ISSUED 248 PM CDT Fri Jun 21 2019/

SHORT TERM (Tonight through Saturday Night)...
On this Summer Solstice day, it's no surprise that it is hot and
humid in South Central Texas. Underneath high pressure ridging, dry
conditions expected for the rest of the afternoon and into tonight,
with only slight chances along the Rio Grande Plains as some
convection building over the high terrain in Mexico may cross over
into that area. Moisture increases in the mid levels as the ridging
moves east, leaving Saturday just slightly cooler than today which
may be enough to stay out of heat advisory level. Only slight
chances for showers and storms for Saturday.

LONG TERM (Sunday through Friday)...
Sunday the rain chances go up starting with any remnant outflow
boundaries from previous convection in North Texas. As the pattern
continues to become more unstable in the southwest flow aloft, Sunday
night through Tuesday carry higher rain chances. Higher chances and
heavier downpours will be east of I-35, though most of the area will
have at least a slight chance. By Wednesday, ridging moves back in
from the west and dry conditions are expected through Friday.
Temperatures, of course, remain warm with highs ranging from the low
90s in the Hill country and mid to upper 90s elsewhere.
