.AVIATION [06Z TAF Issuance]...

Nighttime Microphysics RGB shows a pretty good progression of
cloud cover increasing over SE Texas from 01Z to 0530Z tonight.
Most terminals have had ceilings lower to MVFR and IFR levels.
That trend should continue and expect IFR/MVFR ceilings to
continue through much of the morning. There still looks like a
chance of showers in the area in the morning ahead of the lead
short wave trough and jet streak. Ceilings still look to improve
through the afternoon. 00Z guidance not all that different from
previous guidance with possibly some TSRA for KCLL and KUTS but
the capping will be stronger south of those terminals. A line of
showers with the front looks like a good bet so will go with SHRA
in the rest of the TAFs. Frontal boundary should push towards the
coast after 06Z Sunday with a line of showers. Cap may erode
enough for some TSRA but still enough time to evaluate that with
future TAF updates.
