.AVIATION [06Z TAF Issuance]...

Dense fog and LIFR conditions seemed confined to the northern
half of the TAF sites. But KCXO has recently become MVFR after
being socked in with fog. The expectation is for KCLL/KUTS/KCXO to
remain with dense fog through the morning hours. The Houston
terminals southward have MVFR/VFR conditions but like the other
areas, there is still the potential for IFR conditions to develop
with fog and low clouds. Along the coast VFR/MVFR conditions may
be more likely. TAFs at KLBX/KGLS still indicate a transition to
IFR but there is more of a chance that this may not happen. Models
continue with rain chances starting in the morning hours and with
isentropic upglide with the front stalled off the coast, think
thunderstorms will be limited. Rain/drizzle along with fog and low
clouds should continue for much of the day Monday with only brief
periods of improving conditions.

.PREV DISCUSSION /Issued 901 PM CST Sun Dec 17 2017/...

A dense fog advisory has been issued for portions of the Brazos
Valley and Piney Woods region from 10 PM tonight through 10 AM
Monday. Visibilities in those areas have already fallen to 1/2
mile in some locations and will likely only worsen as the night
goes on. This fog, along with grey and rainy conditions closer to
the coast could really slow down the Monday morning commute across
the area. The advisory may need to be expanded southward later
tonight, but there is currently not as much confidence that those
areas will see widespread dense fog.
