Oct. 4 20

 The sky looked to be clear, at my house in northwest Houston, TX, during the early and mid-morning, and night. High white alto stratus clouds looked to cover most of the sky, at my house and neighborhood, during the late morning. White and grey low stratus clouds started to cover most of the sky, in northwest Houston, TX and Katy, TX, during the early afternoon. White and grey stratus clouds looked to cover most of the sky, at my house in northwest Houston, TX and Katy, TX, during the mid-afternoon. Low white and grey stratus clouds, looked to cover most of the sky in northwest Houston, TX, during the evening. It felt cool, almost cold, during the early morning. It felt cool during the mid-morning. It felt warm during the late morning, afternoon, evening, and night. The wind speeds were calm with maybe some occasional moderate gusts. There was a slight chance for a stray shower in the Houston, TX area. I did not see, feel, or hear any rain drops where I was. I do not know if the Houston, TX area got any rain.

Thoughts: Cold fronts and the tropics. Maybe one of them will bring Houston, TX some rain. Although I am still enjoying the sunny, warm, and dry weather!

.AVIATION...

For the 00Z TAFs, clouds around 6000-8000 feet partly associated with
a weak cold front will continue working their way southward this evening
and gradually diminish/dissipate. Still watching for possible evening
SHRA development, generally to the E of I-45. VFR overnight and throughout
the day tomorrow with mainly NE under 10 knots. 42

.PREV DISCUSSION... /ISSUED 356 PM CDT Sun Oct 4 2020/

SHORT TERM [Through Tuesday Night]...

A weak cold front will be pushing southward through the area over
the next few hours. You really won`t notice the FROPA other than
an increase in cloud coverage and a slight northeasterly wind
shift. However, CAM guidance continues to show some isolated
showers popping up along the boundary as it moves southward this
evening east of I-45. If these showers do materialize you may get
a light sprinkle, but the rain will most likely evaporate before
reaching the ground (virga). The temporary increase in clouds
quickly dissipates tonight, and mostly clear skies (maybe some
cirrus) will remain in place through Tuesday as high pressure
settles in over Texas.

Don`t expect much change to the temperatures that we have been
seeing with daytime highs in the mid 80s and overnight lows in the
upper 50s to low 60s.

LONG TERM [Wednesday Through Sunday]...

Much what goes on in the long term period will be determined with
what goes on in the tropics (see the tropical section below for
more detailed information). Latest guidance has trended to a
stronger mid-level ridge over Texas midweek, keeping Tropical
Storm Gamma further south. With Gamma further south, the tropical
moisture will struggle to makes its way into our area. So have cut
back PoPs slightly on Wednesday/Thursday from the previous
package. Gamma will still be in the Bay of Campeche by the end of
the week, but uncertainty beyond Friday is fairly large with
respect to both its track and strength. There is also (now)
Potential Tropical Cyclone 26 that is located in the southern
Caribbean. The aforementioned ridge should help to steer this
system east of our area by the end of the week. However, a weaker
or further westward high could allow for the system to slip
closer to our area. So, please continue to monitor the forecast in
the coming days as things can always change.

High temperatures through the week will be continue to stay in the
mid 80s, though if the high pressure remains in place then
temperatures could climb into the upper 80s by the end of the
week. Overnight lows will also stay in the upper 50s to low 60s
through midweek, then begin to rise by the end of the week (mid to
upper 60s) as moisture increases.

MARINE...

Northeasterly winds prevail with high pressure to the north and
Tropical Storm Gamma meandering in the Bay of Campeche. Potential
tropical cyclone 26 in the Caribbean is expected to move into the
Gulf during the middle and late parts of the work week. Expect
increasing swell heights and water levels in association with both
systems. Caution and/or advisory flags may be required at times
(mainly offshore) Tuesday night and beyond. Current guidance
projects water levels will probably run 1.0-1.5ft above
normal...below a significant coastal flood threat, but still worth
keeping an eye on things. Same goes for an increasing risk of rip
currents along area beaches.

TROPICAL...

First lets talk about Gamma. Tropical Storm Gamma is currently located
over the northern tip of the Yucatan Peninsula where it will
remain through the next day or so before turning southwest towards
the Bay of Campeche. Once it gets into the southern Bay of
Campeche through the end of the week, it is not expected to move
much as high pressure to the north keeps it suppressed. It will be
dealing with upper level shear and potential land interaction, so
weakening is expected through the next several days. Forecast
confidence in the track and intensity is very low beyond Thursday
and Friday.

The tropical wave that the NHC has been monitoring for the past
several days in the Caribbean has been classified as Potential
Tropical Cyclone 26. It is expected to strengthen into Tropical
Storm Delta by tomorrow afternoon and continue to strengthen as it
heads towards western Cuba. It will move into the southern Gulf of
Mexico in a few days, where additional strengthening is
expected. High pressure over Texas and the western Gulf should
steer the potential Delta to the east, so those along the northern
Gulf Coast should closely monitor the forecast in the coming days.
As of right now, it is not likely that Delta will bring direct
impacts to SE Texas, but we will continue to monitor the situation
in case things change (for both Gamma and PTC 26).
