Mississippi State just barely escaped defeat yesterday in overtime against Arizona. We play LSU next Saturday at 11. After that, we play South Carolina then Alabama. It's going to be a rough next few weeks.

Since this is now a college football board…..Geaux Tigers!!

I’m taking my kids to their first ever away LSU game at Mississippi State next weekend from League City. Can’t wait!
Starkvegas, here come the Pas Bon’s. Whoop!

High temp next Saturday in Starkville should remain in the 70’s. :D

I am bit happy with UH performance last night. Quite frankly their first two games have been a disappointment. Their season is over already :roll:

Maybe the Texans will surprise some folks. Doubtful but can’t be worse than the last almost decade

Rookie QB, rookie OC, and a banged up OL sounds about like David Carrs rookie season 2.0.

For me personally, I don’t really care about cooler temps. I just want some rain. Fronts coming in changing the humidity and temperatures gets people sick, including me. If a front comes in, I wouldn’t want it to be anything too strong. A slow gradual decline in temps over the next few months is what I’d prefer.

But no, you’ll have to wait till October for that. The rest of September will be above average temps.

Dewpoint in the upper 50s here. No rain, but when the heat index actually matches the ambient temperature, I'll allow it. :lol:

...New AVIATION...

.SHORT TERM...
(Today through Monday Night)
Issued at 343 AM CDT Sun Sep 10 2023

Some southward moving showers and embedded thunderstorms have dotted
the area early this morning, mainly near and to the west of the I-45
corridor where deeper moisture levels are found. The shortwave partly
responsible for this activity will continue sagging southward into Deep
South Texas this morning, and will gradually/eventually take our activity
off the coast. The remainder of the day looks dry and warm with lowering
dew points and precipitable water values along with decreasing clouds.
High temperatures inland will range from the low to mid 90s northeast
to the mid to upper 90s for the remainder of the area. Looking for a
cooler September night? Expect to see lows tonight in an upper 60s to
low 70s range for much of the area (could see a couple spots drop into
the mid 60s in/around the Crockett area and surrounding locations).

We will start out the week on Monday with mostly sunny skies and highs
mainly in the mid to upper 90s. Monday night should be mostly clear
with lows in an upper 60s to mid 70s range.

.LONG TERM...
(Tuesday through Saturday)
Issued at 343 AM CDT Sun Sep 10 2023

An upper level, cutoff low over the Upper Great Lakes will attempt
to push a weak cold front into SE Texas around Tuesday
night/Wednesday morning. This boundary should become quasi-
stationary, looming over the region in the days following as it
gradually drifts further north. Shortwave impulses and PWs ranging
from 1.6" to 1.9" should bring daily shower/thunderstorm chances
with the aforementioned boundary. Global ensembles have
Thursday/Friday progged for the highest rainfall totals, with PWs
looking to exceed 2.0" during this period. 850mb temperatures look
to drop to around 17-20C, ushering in "not as hot" weather for
Southeast Texas. Daytime highs should be in the upper 80s to mid 90s
with overnight lows in the 60s and 70s.

On Saturday, global models feature another shortwave trough digging
across the Plains, pushing another weak cold front through SE Texas
into the Gulf of Mexico. This should drag temperatures down a tad
more, with Saturday`s highs progged to drop into the mid 80s to
lower 90s.

A PSA about Heat and heat illness, especially in the elderly or susceptible because of illness. Last Saturday the high reach 104°F before gametime and it was more humid (higher DP) than expected. Evidently, one of the neighbors died while gardening last Saturday. :( They were a retired geologist.

Limit exposure, especially in the sun of 15-20 minutes if the heat index approaches 100°F or more, before hydrating and cooling off.


Slow down. Strenuous activities should be reduced, eliminated, or rescheduled to the coolest time of the day. Individuals at risk should stay in the coolest available place, not necessarily indoors.
Dress for summer. Lightweight, light-colored clothing reflects heat and sunlight, and helps your body maintain normal temperatures.

Foods (like proteins) that increase metabolic heat production also increase water loss.
Drink plenty of water or non-alcoholic fluids. Your body needs water to keep cool. Drink plenty of fluids even if you don't feel thirsty.

Do not drink alcoholic beverages.

Spend more time in air-conditioned places. Air conditioning in homes and other buildings markedly reduces danger from the heat. If you cannot afford an air conditioner, spending some time each day (during hot weather) in an air conditioned environment affords some protection.
Don't get too much sun. Sunburn makes the job of heat dissipation that much more difficult.

I was at that game and never even really broke a sweat. It was fairly comfortable for me but I was in the shade so that helped a lot.

It feels great in the shade with 50's dew points and 20's humidity currently! Having football on with better weather just feels right!

Just got to southwestern Utah and it's pouring. Crazy that I had to go all the way to the desert to see rainfall and can't get anything 20 miles from the GoM.

Of course. Zion usually gets about 16 inches of rain a year!

We have an epidemic of BDS: Battered Donut Syndrome.

- CLL has virtually the same NWS forecast for Friday.

...New AVIATION...

.SHORT TERM...
(Today through Tuesday Night)
Issued at 236 AM CDT Mon Sep 11 2023

A drier airmass has filtered into much of Southeast Texas as most
2 AM temperatures are in a mid 60s to mid 70s range and most dew points
are in the 50s and 60s. Some high clouds are edging toward the area
from the north. Look for mostly sunny to partly cloudy skies today with
highs mainly in a mid to upper 90s range. Eyes turn toward the northwest
and west for the rest of the period as shortwaves/disturbances edge
eastward across the state. Area moisture levels will gradually rise,
and we`ll have very low rain chances back into the forecast Tuesday
and Tuesday night for our far northern counties and for some spots
close to the coast/bays and offshore. Tuesday could end up being the
last very warm day for a majority of the area with highs in a low to
upper 90s range.

.LONG TERM...
(Wednesday through Sunday)
Issued at 236 AM CDT Mon Sep 11 2023

A quasi-stationary boundary should loom over the region on
Wednesday, gradually drifting further north in the days following.
Shortwave impulses and PWs ranging from 1.8" to over 2.0" should
bring daily shower/thunderstorm chances with the aforementioned
boundary. 850mb temperatures look to drop to around 16-20C, ushering
in "not as hot" weather for Southeast Texas. Daytime highs should be
in the upper 80s to upper 90s with overnight lows in the 60s and
70s.

Over the weekend, global models feature another shortwave trough
digging across the Plains/Mississippi River Valley. This feature is
currently progged to bring another weak frontal boundary to SE Texas
Saturday night/Sunday morning. This should drag temperatures down a
tad more, with highs progged to drop into the mid 80s to mid 90s.
PWs drop quickly behind the front, with drier conditions progged to
set in early next week.

.MARINE...
Issued at 236 AM CDT Mon Sep 11 2023

Periods of light to moderate onshore flow can be expected over the
next several days. Rain chances increase on Tuesday as a weak front
approaches the area. Afterwards, expect scatted to isolated showers
and storms daily with seas of 1 to 3 feet.

.FIRE WEATHER...
Issued at 236 AM CDT Mon Sep 11 2023

Dry air sticks around today with minimum relative humidity values in
a 25-35% range with east to southeast winds peaking at around 10 mph.
Similar winds can be expected on Tuesday, but minimum humidities will
be a little higher, around 30-40%. Fire weather conditions will remain
elevated until rains come back to the area beginning around midweek
and continuing into the start of the weekend. Burn bans remain in effect
across all of Southeast Texas.

Update from Jeff Lindner:

Increasing rain chances continue in the forecast for mid to late week.

Surface high pressure to the northeast of the area this morning has allowed a dry air mass to move across the region with the passage of a weak frontal boundary on Saturday. This taste of drier air will be short lived as moisture will begin to return on Tuesday with increasing dewpoints and southerly winds.

A series of upper level disturbances will round the northern and northeastern portions of a flattened upper level ridge of high pressure over MX and these disturbances will result in complexes of thunderstorms over NW TX into NC TX. The first of these complexes will approach SE TX on Tuesday, but it is likely that the local air mass will still be in the process of moisture recovery and this activity will weaken and dissipate…could see some showers and storms around the College Station area.

Better rain chances begin on Wednesday and continue into Thursday and Friday as a weak front sags southward and stalls near the region. With moisture having recovered by this time and several disturbances aloft moving into and across the area…periods of showers and thunderstorms will be likely especially on Thursday and Friday.

While it is likely not going to rain everywhere each day…much of the area stands to see the potential for 1-2 inches of rainfall north of I-10 and .50 to 1.0 inch south of I-10 in the Wed-Fri period.

Weak front will push south into the Gulf waters late Friday into Saturday allowing another dry air mass to move across the region. This air mass also looks a bit cooler than this weekend, but this is still several days out so won’t get overly excited about any truly cooler temperatures, but certainly a drier feel to the air is likely by next Sunday.

Fire Weather:
Dry dewpoints and low afternoon humidity values still plague the area and there were several fire starts yesterday even across areas that saw rainfall on Friday afternoon into Saturday morning. With the dry air mass in place again today and much of the fuel loads remaining critically dry…fire concerns will be high. Good news is winds will be light from the northeast and east and humidity values start to increase on Tuesday. Hopefully mid to late week rain chances materialize into widespread wetting rainfall before yet period of dry air and slightly stronger winds arrive next weekend.

Forecasted Rainfall (7 Days):
