...New AVIATION...

(This evening through Wednesday Night)
Issued at 218 PM CDT Tue Apr 23 2024

A look at the satellite this afternoon will confirm from above
what you can also likely see from your nearest window - it`s
mostly cloudy out there. The exception is out towards the Piney
Woods in parts of Houston, Trinity, and Polk counties, where it
will remain tree canopy that blocks your view of the sky, not the
clouds. Despite that, we are continuing the expected warming
trend, with temperatures reaching into the middle 70s throughout
the region, on pace for highs in the upper half of the 70s for
most in the next few hours.

If you like your nights a bit chillier - firstly, I congratulate
your good taste, but also I have some bad news. With clouds
staying in place, and onshore flow continuing to pump in higher
dewpoints, we are assured to have a higher temperature floor
overnight as well. Lows tonight look to be a good 10-15 degrees
higher than last night, ranging from the low 60s in the far north
to right around 70 degrees on the Gulf. This of course, sets us up
for another warm day tomorrow, in spite of another day that`s
anticipated to be mostly cloudy. Starting as warm as we are, highs
should nudge up to around or above 80 degrees area-wide.

Outside of the temps and continued onshore winds, there`s not a
whole lot else of note in the short term. I did struggle with rain
chances. We`ve got a decently low cloud base and increasing moisture,
which has me thinking we can manage a smattering or real light,
real quick sprinkles/light showers. But since these tend to struggle
to manage more than a trace of rain, and the PoPs are defined by
having measurable rain, I chose to keep those rain chances low,
below the threshold for a slight chance mention. Even if you stipulate
one of these quick hitter sprinklers, the odds aren`t great for
getting even a hundredth of an inch out of them.    Luchs


(Thursday through next Monday)
Issued at 218 PM CDT Tue Apr 23 2024

Upper level ridging from Mexico into Texas will be transitioning
eastward on Thursday. This will open us to more of a swly flow
aloft with broad mid-upper troffiness situated across the western
CONUS as we close out the week.

As far as the local forecast goes, look for increasingly breezy
conditions as we head into the weekend as the pressure gradient
tightens. With steady winds coming in off the Gulf, I`d anticipate
mcldy skies, humid conditions and overnight low temperatures
resembling those of early June (low 70s). Though slightly above
normal, cloud cover should keep readings in the 83-87 range most

Despite somewhat moist conditions, other some some diffuse impulses
moving overhead from time-to-time, there really isn`t much in the
way of distinct triggers or focusing mechanisms needed for
widespread chances of rain. There are a few possible exceptions
we`ll be keeping an eye on (mainly for the northern parts of the
CWA). Looks like there will be a few shortwaves drop into the base
of the trof then eject into the Plains. As this occurs we might
see the tail end of some associated bands of shra/tstms try to
sneak into portions of the area. Friday and Sunday would be the
days I`d be looking at if so. 47


(00Z TAF Issuance)
Issued at 632 PM CDT Tue Apr 23 2024

Mixture of VFR/MVFR CIGs this evening. A few sites projected to
drop to lower end MVFR and perhaps even IFR briefly during the
overnight into early morning hours. S/SE winds will become light
and variable later tonight before returning to S/SE Wednesday
morning. Light showers will be possible, briefly, Wednesday


Issued at 218 PM CDT Tue Apr 23 2024

Onshore flow will continue through the week. Winds and seas will
be on an upward climb later in the week and weekend as a long fetch
of moderate to strong southeast winds set up across the Gulf.
Small craft advisories are looking increasingly probable as are
high risks of rip currents on area beaches this weekend. 47
