Update
Forecast for tonight is largely on track, so most things only
needed minor, cosmetic changes to be seamless with observations.

Have gone ahead and trimmed down pops in the near term as any
rainfall this evening has been far, far to our northwest so far.

Ultimately, this is not a large change, but should reflect better
certainty based on trends of this evening.

Discussion...

surface high pressure over the sabine river valley has kept
regional winds light but its eastward movement into the eastern
u.S. Tomorrow will assist in swinging near to medium term winds
south to southeast. Clouds will begin to thicken up and lower
from west to east overnight and return flow off the gulf will
strengthen to breezy daytime levels over the weekend. This in
response to a somewhat shallow central plains trough low on its
eastward trek from the lees tonight into the ohio river valley
late Sunday. Rain chances will be low with the highest chances for
experiencing any measurable 60 hour rain occuring across the
northern half of the cwa. Most southeastern texas communities will
experience an occasional period of light rain or sprinkles... With
northern tier counties experiencing an isolated thunderstorm...

during the daytime hours either Saturday and or Sunday. Increased
lower level moisture will ensure more mild evenings with days
still warming into the average middle to upper 70s despite the
mainly overcast skies.

A weak cold front will move across east texas during the day Monday.

Areas of rain with isolated thunderstorms may form out ahead of
this boundary as it slowly moves through during the warmth of the
day. Other than turning winds north to northeast by Monday evening,
this front will have little to no impact on the day-to-day weather
pattern going into the final week of the month. A spring weather
pattern that appears to be in-line with the season as Tuesday
through Thursday's conditions will be nice. Partially cloudy to
sunny days with onshore winds re-establishing themselves Wednesday
afternoon. Weak southern plains upper ridging spells dry days
with overnights cooling into the low to mid 50s... Days warming
back up into the middle to upper 70s at mid week. A much more
aggressive Friday (or Saturday?) cold frontal passage will
significantly increase precipitation chances and introduce the
mention of possibly strong or severe storms. 31

Aviation
For most TAF sites,VFR overnight. Similar to last night, could see
some fog develop at lbx and sgr with low visibilities ceilings. For
now, just indicating MVFR but will monitor amend if it looks like
lower restrictions will develop.VFR tomorrow, and expect a cloud
deck around 6000-8000 feet to develop during the day. Look also
for increasing S to SE winds with some locations getting gusts to
around 20 knots. For now, only mentioning vcsh at cll, but we'll
have to see how things evolve as the day progresses. 42
marine...

winds will remain light out of the southeast tonight, before
increasing tomorrow as high pressure shifts eastward and next
weather system approaches. In response, expect seas to build
through the weekend up to 2-4 feet Saturday afternoon into early
next week. A cold front moves through the region Monday with north
to northeast winds behind the front probably necessitating a sca.

We could see a few showers pop up Saturday, with rain chances
increasing for Sunday and Monday as front nears. Evans
