.AVIATION...
VFR conditions should prevail across most TAF sites through the
TAF period. Could see lower visibilities down to 4 SM at CLL and
CXO based off the what the model soundings and MOS guidance are
indicating. With PWs filtering into the region more over the
western half of the CWA, think the moisture along with the
decoupling of the winds at CLL, could lead to some BR and lower
visibilites. Since CXO sits a little lower in terms of elevation,
winds should decouple and with the available moisture also
thinking could some BR at CXO. A MVFR deck at IAH and HOU will set
in early morning tomorrow, but SH and TSRA development should
remain south of HOU and hold along the coast. Therefore, indicated
possible MVFR during the morning hours for GLS and LBX as well,
but decided to keep out VCSH and VCTS for now.

DISCUSSION...
Only a few tweaks to the forecast for the update...mainly to ac-
count for ongoing cloud cover trends (particularly at the coast).
Not expecting much by way of precipitation this afternoon given
the slightly lower PWs and stronger cap over the area. 41
