.AVIATION...
VFR conditions late this evening should continue through the next
6 hours or so before we begin to see stratus developing/moving
northward from the SE TX/S LA coast and effecting our terminal
airspace overnight. Believe this will come in as mostly MVFR
ceilings with heights near 1-2kft but will need to watch for some
IFR ceilings briefly late tonight through the early morning hours
on Wed. Pressure gradient will remain strong but with a developing
inversion overnight, we should see winds decouple slightly. Strong
SSE winds will return with earnest on Wed with gusts upwards of
25kts possible across all but the MLU/ELD terminals.

Convection will be moving our way overnight in the form of a
broken line of strong to severe thunderstorms but should begin to
weaken in coverage and intensity to our west and northwest near or
just after 12z Wed. Made mention of tempo TSRA at the TYR/GGG
terminals for the morning hours on Wed just in case this
convection moving our way stays in tact. Otherwise, we await on
daytime heating and reorganization of strong to severe
thunderstorms by late afternoon into the evening hours mainly
along and east of a line from the LFK/SHV/TXK terminal eastward in
the 21z-00z period and advancing eastward towards the ELD/MLU
terminals just beyond this TAF cycle.

PREV DISCUSSION... /issued 1022 AM CDT Tue Mar 28 2017/

DISCUSSION...
Current forecast is on track this morning. Weak frontal boundary
across mainly the I-20 corridor could be the focus for scattered
showers and thunderstorms this afternoon. Skies to remain mostly
cloudy due to fairly thick layer of low-level moisture across the
region. May see a few breaks in the afternoon but would still
qualify as mostly cloudy. High temperatures forecast to range
from highs in the 80s south of the front and mid to upper 70s
north of the front. /05/
