I thought that’s what Texas was gonna do against Rice but nope, they looked pathetic. Honestly, I doubt A&M will look much better. We’ll see.
Weigman is far more accurate than King, Johnson. WR corps is more talented. We're scoring more now and will. Just have to remain healthy...

Durkin's defense looks the same, although the talent is monstrously massive and good. They will be the concern this season. A&M should have fired Durkin after last season as well.

Weatherwise, about 30% chance of rain in CLL Sun - Tuesday. Not anticipating much - maybe an impulse or seabreeze hit.

50% chance in HOU.

Then, back to the usual.

Area Forecast Discussion
National Weather Service Houston/Galveston TX

...New AVIATION...

.SHORT TERM...
(This evening through Sunday Night)
Issued at 350 PM CDT Sat Sep 2 2023

Latest radar and satellite imagery continue to show scattered
showers with a few thunderstorms slowly moving inland along the
seabreeze. Most of this activity should remain over the coastal
counties; however outflow wind boundaries could potentially move
further north through early this evening. This could result in gusty
winds up to 20 knots along any boundary(ies). Any showers/storms
should gradually taper off through sunset with the loss of daytime
heating. A quiet night can be expected with light and variable winds
and lows mainly in the upper 70s.

The weather pattern will gradually change in the next 24h as an
upper-lvl low moves just north of the region and PVA increases. In
fact, PWATs into the 1.6 to 1.9 inch range can be expected on
Sunday.
This scenario should allow for widespread chances of rain
and storms on Sunday. The best chances should be in the afternoon
with the sea/bay breeze.

Well above normal temperatures continue with us. Highs will
generally climb into the upper 90s to 101F. The main difference on
Sunday will be humidity levels. With increasing WAA and moisture,
it will feel more humid. Peak heat indices up to 108F will be
possible.

.LONG TERM...
(Monday through next Friday)
Issued at 350 PM CDT Sat Sep 2 2023

Starting next week, a mid/upper low looming over the Lower
Mississippi River Valley should slide north, subsequently getting
ingested into a stronger upper trough/low passing through the
Northern Plains. The associated surface low over the Plains with
surface high pressure across the SE CONUS should tighten the
pressure gradient and usher in steady onshore flow throughout most
of the week. PWs rise to 1.6 - 1.9 inches, with weak capping and
weak impulses conducive for scattered showers/storm development,
especially during the afternoon along the sea breeze.
Areas that
don`t receive rainfall will likely see highs in the 90s/lower 100s,
with heat indicies of 101-107.

Ridging rebuilds across the SW CONUS by mid next week, with peak
500mb heights climbing to 596 dam by the end of the week.
While SE
Texas looks sit on the peripheral of this ridge, increasing
subsidence should work to reduce rain chances through Friday. 850mb
temperatures climb to around 21-25C near the end of the forecast
period, bringing more widespread triple digit highs across the
region.

Man, Idalia is taking the scenic route and still chugging along. Caribbean, Florida/Georgia/ S. Carolina, Bermuda and next stop, Nova Scotia then off to Newfoundland.
I wonder what was the longest trekking storm ever.

Yes, I have a sister across 45. It’s been a scary couple of days. I hope they get it contained soon.

I have 30% today and 50% tomorrow and Tuesday. Wouldn’t be surprised if those are trended down as the day goes on and into tomorrow.

There were some scattered storms with the sea breeze yesterday south of I-10. Fingers crossed they continue or cover more area before the the faucet is sealed shut. Back to 100+ in the foreseeable future after Tuesday. :roll:

The activity yesterday was more than what many of the CAM mesocales were showing, actually. We'll see what happens today through Tuesday.

A brief tropical shower enough to get the yard wet but that was it. Hoping for more widespread showers and thunderstorms tomorrow.

It seems to rain in your area more than it does in most others.

The immediate coast at Brazoria + Galveston counties (including Galveston Island) represents a good microclimate that stay relatively wet and humid throughout these prolonged-dry spells: if nothing else, the area maintains high dewpoints that mitigates the worst of dessication/wildfire threats that spring up inland.

The coast at Brazoria county, most crucially, has a sort of "convex" shape: this enhances sea-breeze convergence, which can aid in favoring convection. Another "convex convergence zone" exists from Galveston county up I-45 (often into Hobby Airpoty/Inner Loop Houston), provided that Galveston Bay produces its own breezes in addition to the main Gulf breeze (which I think it does, since you can often see clear skies over the bay, while land areas have cumulus development).
