.AVIATION...
All sites excluding LRD expected to see LIFR conditions from
around 00z this evening to 12z Wednesday morning as a nearby
coastal trough brings a low stratus deck into the area. LRD is
expected to remain MVFR through this TAF cycle. Have extended the
potential for freezing drizzle south to include ALI and CRP as
temperatures have not warmed up as previously expected and are
still below freezing. Light ice accumulations are possible as the
precipitation pushes through tonight into tomorrow. All sites are
expected to return to MVFR conditions by 21z Wednesday.
