.AVIATION...
Scattered, outflow dominated shra/tstms around the metro area
should dissipate in the next couple hours with the loss of
heating. Further n/ne toward the UTS/CXO terminals we're watching
a slightly more organized cluster of storms sagging into the area.
These too should diminish, but may persist and impact those
terminals through 2-3Z or so. Localized heavy rain and wind gusts
to 40kt possible in the strongest cells. After 3z or so, expect
VFR conditions to persist areawide. As with previous days, iso/sct
precip development offshore before sunrise, transitioning inland
late morning & afternoon. Boundary that is presently generating
the east Tx storms moves a bit closer on Sunday, so would
anticipate generally more coverage than we saw today - especially
east of a CLL-GLS line. 47
