For the 24/06z TAFs, mid and high level clouds will prevail for
most of the TAF period. However, showers are beginning to develop
across Central Texas ahead of an approaching upper trough. As this
trough ejects from the Rockies and into the Plains, the showers
will spread from southwest to northeast across the area during the
day Wednesday. All TAF sites will be affected. Showers should
begin at KLFK around sunrise and should reach KELD and KMLU late
in the period. Expect ceilings to lower into the MVFR category at
all terminals after 26/00z as the rain prevails.

Hazardous Weather Outlook For LOWER ST. MARTIN County, LA

435 PM CDT Tue Oct 23 2018

 DAY ONE  Tonight
Showers will diminish through the evening. Additional showers will
develop and begin moving into southeast Texas and western
Louisiana late tonight. Rainfall totals will be light, generally
less than one tenth of an inch.

 DAYS TWO THROUGH SEVEN  Wednesday through Monday
Showers and isolated thunderstorms will become more widespread 
Wednesday into Thursday as a strong upper level disturbance lifts
the remnants of Eastern Pacific Hurricane Willa across old 
Mexico, Texas, and the northwest Gulf of Mexico. 

Periods of heavy rainfall will be possible during this time, with
rainfall amounts estimated to be 1 to 2 inches along and north of
I-10, with 2 to 3 inches expected further south to the coast. 
Isolated higher amounts will be possible, but widespread flooding 
is not expected at this time. Low lying locations and urban areas 
could see some minor flooding during heavier rains. In addition, 
water levels on area rivers could rise, leading to localized 
flooding in a few locations.

The risk for severe weather is low, but a few strong storms could
develop over south central Louisiana Thursday afternoon. The
stronger storms will be capable of producing gusty winds and heavy
rainfall, as well as occasional cloud to ground lightning.

Dry weather is expected for Friday through Monday.

Spotter activation is not expected at this time.
