PREV DISCUSSION... /issued 349 PM CST Thu Feb 22 2018/

DISCUSSION...Radar showing scattered showers and a few
thunderstorms over interior southeast Texas. Activity just along
and ahead of a retreating frontal boundary. A Flash Flood Watch
is in effect for this area as well as Vernon parish where
significant rains fell yesterday. Watch will be allowed to expire
at 6 pm as activity diminishes.

Unseasonably warm and humid late February weather will continue
into Saturday with rain chances remaining limited and primarily
for afternoon convection. Models bring aforementioned retreated
front back over the region Saturday night as shortwave energy
advances across the plains then northeast. Cooler temperatures
following. Boundary is expected to stall over the near coastal
waters maintaining elevated showers and thunderstorms across the
region through Sunday. A second shortwave advancing across the
plains will push active boundary deeper into the gulf late Sunday
into early Monday. Rain chances then lessen for the first half of
the work-week.

MARINE...A long fetch of warm and moist south to southeast
winds advancing over the relatively cooler shelf waters of the
northwest Gulf will continue through Saturday. This will result
in a continued high probability of sea fog development. A
shortwave trof advancing through the plains will advance a cold
front into the near shore waters Saturday night where it is
expected to stall. Showers and thunderstorms will accompany the
front and continue into Sunday, finally kicking out Sunday night
as a second shortwave trof advances through.
