.AVIATION...
VFR conditions continue with 8000-12000 ft decks in place across 
the region. Most of the light rain has pushed out over the Gulf
waters this evening. Light and variable NE flow will continue
through the overnight hours, increasing in speed to between
6-11 kts by tomorrow late morning. The possibility of some light 
rain along the coast continues to decrease, as latest model
guidance continues to keep most precipitation offshore.

.PREV DISCUSSION... /ISSUED 955 PM CDT Sat Mar 16 2019/ 

UPDATE...
Very few changes made with this update...as going forecast has
things well handled.

Pattern to continue with surface front offshore but stream of
mid and high level moisture streaming up from the SW with
subtropical jet. Disturbances now and then ripple up. One such
disturbance now exiting to the east taking with it and area of
showers...mainly offshore. 

Although another disturbance will likely ripple up 
tomorrow...trend will be for the showers to be displaced farther 
south...so think most land areas will be dry for rest of tonight 
and Sunday. This scenario consistent with bulk of the model
guidance. Exception may be right along the coast...especially 
near Matagorda Bay Sunday morning. Going forecast has this well 
handled. Looking at RH fields looks like the 10000 foot deck will
also be displaced farther south...with overcast likely thinner
than occurred today...in some areas primarily high cirrus.
Northern counties will likely even see some sun on Sunday.
