1148 PM CDT Sun Aug 25 2019

.AVIATION [06Z TAF Issuance]...
Band of MVFR ceilings 1500-2000ft spreading inland and expect
periods of VFR/MVFR conditions through sunrise for mainly
CXO/UTS/CLL. High-res guidance has been doing a good job of
capturing the lower ceilings. Showers should develop over the
coastal waters around 09z and then move inland 11-15z but should
be mainly over the southern terminals. Guidance has been trending
much drier than yesterdays runs and have kept with the VCSH
wording in the TAF for the 15-20z time frame. Can`t rule out
isolated thunderstorms for the HOU area southward. Skies should
again clear out quickly Monday evening.

.DISCUSSION...

Per WV imagery, we are seeing a good bit of drier air move into
CWA from the NW at this time. This looks to be helping with the
decreased activity and clearing skies at present. Did make some
tweaks to the near-term grids to account for these trends. 41
