623 am cdt Fri aug 23 2019

Aviation [12z TAF issuance]
Fairly messy day of flying conditions ahead as an upper trough
moves up the western gulf coast. Main hazard will be the
development of scattered to numerous showers and thunderstorms
from cxo coastward.VFR CIGS and vsby for the most part, but both
ceilings and visibility may degrade to MVFR or worse when rain and
storms impact any terminals.

Have tried to sketch out the most likely time for impacts to
specific terminals with tempos, but be on the lookout for
amendments today!

Prev discussion issued 359 am cdt Fri aug 23 2019
Discussion
- best chances of storms today and Saturday. Main hazard will be
locally heavy rainfall with mainly street flooding possible.

- chances of storms continue early next week but with coverage
closer to isolated to widely scattered.

- ridging builds over texas again leading to high temps back in
the upper 90s next week.

Short term [today and tonight]
Radar shows a bit of activity over the gulf waters and immediate
coastal areas late tonight, setting the stage for another day of
scattered showers and thunderstorms. Goes-east shows precipitable
water increasing towards the gulf, associated an upper trough that
shows up very nicely on mid-level WV imagery.

There is not a ton of convection going on with this feature quite
yet, but there's a handful of showers popping up over the gulf. As
the upper low and its moisture surge make their way up the western
gulf coast, we should see it enhance the typical diurnal pattern
of showers and storms. Because of this, I go as high as likely
pops near the coast, but still keep a pretty sharp gradient with
slight chance low end chance pops in the far inland around college
station.

Given the amount of moisture - precipitable water exceeding 2.25
inches - with deep warm cloud depths making for efficient precip
moving into the picture, I certainly can't rule out some
localized torrential rainfall from the strongest of the storms. If
that falls over the wrong spots, we would certainly see a
smattering of flooding on roads and poor drainage areas. However,
a lot of the items on the checklist for widespread heavy rain
aren't really there, which is reassuring.

Luchs

Long term [Saturday through Friday]
Saturday's forecast looks to be a wash rinse repeat of today's
forecast as higher moisture lingers over the area and the tropical
wave located between SE texas and SW louisiana. Upper level
ridging is virtually non-existent over the area so no real
subsidence to worry about and convective initiation will be more
of a function of day time heating and convergence from local
boundaries moisture gradients. Precipitable water values will
certainly be in that 2.1 to 2.3 inch amounts. Storm motions should
be enough to keep storms moving to limit the overall flood threat
but no doubt a storm could cause street flooding with this much
moisture. Sunday into Monday we see a decrease in rain chances as
precipitable water values rapidly decrease with the tropical wave
moving east away from the region.

To start the work week next week, there is a strong trough over
the northern plains that supports NW flow aloft. Any frontal
boundary with this trough stays north of the area likely stalling
along the red river. By midweek the upper level ridge over the
southern rockies expands over texas. This feature should persist
through the rest of the week so have precipitation chances
lowering through next Friday with high temperatures increasing
back into the upper 90s for a larger portion of the area.
