A lot of people without power right now, with more to come:

In the peak of summer, no less. Sucks.
Also, big chlorine fire at plant near Lake Charles.

Chlorine was used as a chemical weapon in WW1.

Far too close. Props to NHC for keeping the track consistent while diurnal model fluctuations could have caused more chaos.
T&P to the people of SW Louisiana, and major destruction and devastation in Lake Charles. Som many people still without power and/or damage to their homes.
Watching the tropics while back to the usual summer weather. At least the back fence is shored up.

I saw a lot of comments online about not moving the track westward near Houston when this ECMWF ensemble plot came out. #Laura actually made landfall outside of that ensemble (and that model usually has too much spread). Trust the professionals and don’t just worship one model!

^^ I hope it works!
Our daughter was born yesterday at 10:40am and all back home. Thankful as all get out Laura spared us here in Houston! Prayers to all affected. That first cool front can’t get here fast enough!

Yep, agreed. The NHC did a fantastic job. But I saw plenty of Pro-mets with forecasts of this going into Texas. Here is a snippet of a reply I posted on S2K, replying to one of our own friends about falling for the "Euro Ensemble" trap:DoctorMu wrote: ↑Thu Aug 27, 2020 5:19 pmTBF, 3 out of 4 Ensembles had a Texas solution.

That's easy to say in hindsight, so don't be too hard on yourself. It wasn't just the 'Euro ensembles' and some anecdotal evidence the west trend would continue. There were plenty of solid arguments [at the time] for Laura going more west into Texas:
1) Laura, for most of her entire track, had been tracking on the west side of the guidance.
2) The Euro ensembles that showed the western shift, when analyzed individually, made the most meteorological sense at the time [for example, almost all of the ensembles with a stronger storm - a hurricane - went to Texas - and we all knew Laura would be a hurricane]
3) Verified pressures of the ridge versus the model verification, esp. the GFS, showed the SE ridge was a bit stronger than modeled.
4) The Euro Ensembles weren't alone. The UKMET was west, the PARA GFS had shifted west, and a most of the GFS ensembles were on Texas.
For a short period of time, it appeared that Texas, perhaps Galveston, was becoming a certainty.
Indeed. A major hurricane landfall is no picnic. It is made worse with the COVID-19 pandemic.tireman4 wrote: ↑Thu Aug 27, 2020 8:01 am The Houston/Galveston Metro Area dodge a bullet. I want to personally thank all on this board who have and continue to contribute. For the pro and amateur mets, a hearty thank you. This is the third inning of a nine inning game ( or 20 inning like Jason stated). We are on the letter M and the peak month is September, the heart of the Cape Verde season. Be aware. Be vigilant. You have your kits ready. You have your plan worked out.Think of this as a Hurricane Preparedness drill. Our heart and prayers go out to the folks in SWLA and Lake Charles.
I’m ready for cold weather. Lol
Egads, we have much more tropics-watching to go. Ugh.

Ugh. Line of storms just missed my house to the south. Getting hammered at the office though.
Thanks for the best wishes everyone! Stay cool in this heat box!

.AVIATION...
Scattered showers and storms along the coast will expand inland
with heating. Will carry a VCTS for inland TAF sites through the
aftn. Conditions will settle down with the loss of heating after
sunset. NAM fcst soundings show some potential for MVFR cigs after
09z. Not terribly confident and went with scattered decks for now.
Looks considerably drier on Saturday with only isolated PoPs in
the afternoon but probabilities look too low to mention in TAFs.
Moderate SSW winds will become south and decrease later tonight
and should be lighter on Saturday. 43

SHORT TERM [Today through Saturday]...
Main story in the short term will be the potentially dangerous heat
developing across southeast Texas. Temperatures this afternoon will
be able to climb into the upper 90s to low 100s, which combined with
lingering high dew points will lead to heat index values climbing
into the 108 to 110 degree range with some isolated spots even a
degree or two higher. So, a heat advisory has been issued across the
area for today. The main limiting factor for this will be how much
coverage showers and thunderstorms develops this afternoon. Early
this morning, a cluster of thunderstorms developed north of Houston
County, which CAM guidance brings into Houston, Trinity, Polk
counties by mid-morning. If these storms end up getting a bit
further south or west than expected, then heat index values may end
up struggling to get into the heat advisory criteria. Isolated
showers and thunderstorms may also develop along the coast this
afternoon.
Overnight low temperatures tonight will continue to be unseasonably
warm with temperatures only getting down into the upper 70s to low
80s and even higher along the coast. Record high minimum
temperatures will be possible at Galveston tonight.
Saturday is looking to be around just as hot as today, so additional
advisories may be needed, but will wait to see how today pans out
before issuing. Precipitation chances look lower on Saturday, so
temperatures may have even less trouble getting into potentially
dangerous levels.
Fowler
LONG TERM [Saturday Night Through Friday]...
Saturday the upper trough will be departing into LA/MS and the
trailing shear axis shifts into the coastal waters with the
eastward expansion of the subtropical ridging over Nrn Mexico.
this should suppress convection over the northern counties but
the models all continue to support the spread of much high PW air
from the southern Gulf up into TX/LA Sunday afternoon and Monday.
Soundings showing a stout cap over the northern areas Sunday but
closer to the coast and over the Metro 2500-3300 j/kg - little CIN
and K index of 31+. Upper level wise not much of source of
development and at the surface only some very weak
convergence/seabreeze. Earlier runs were more generous with rain
chances Sunday and Monday and now the trend appears to be a little
drier Sunday and more focused on Monday. This overall pattern with
the surge of moisture looks promising but without much upper
support will limit rain chances mainly just chance and see what
later runs come up with for chances. The well above normal
temperatures should see some slight moderating with the
introduction over more moisture into the column but the afternoon
heat indices could well still be hovering in in the 105-108
degree range through Monday. Next issue is a weak early September
cold (cool) front pushing into the Red River late Tuesday
afternoon and eventually getting it close to or possibly even into
the CWA Wednesday late. Don`t want to get any hopes up about
temperature drops...rain cooled maybe along with a chance for
showers and thunderstorms Wednesday night and Thursday.

MARINE...
Moderate southerly flow continues across the Gulf Waters with
seas at around four to five feet, so the caution flags remain
through mid- morning. The flow weakens this afternoon and the seas
should lower, which will continue through the weekend. A chance
of showers and thunderstorms will also continue through the
weekend with the highest change of precipitation occuring on
Sunday. These conditions will continue through midweek next week,
although seas may rise slightly.
Fowler
TROPICAL...
NHC has two areas of interest in the central/eastern Atlantic.
Looking through the GFS/ECMWF the guidance looks to favor these
for some development as they move west/slowly west but dry air may
hamper them. Eventually these move into the Caribbean and possibly
into the area east of the Yucatan/Bay of Campeche in the
Thursday-Saturday time frame next week. The ridge over the eastern
Atlantic looks to strengthen and shift west and the MDR gets more
active mid week. As one would expect for the peak of hurricane
season which says it is still a great idea to check back every few
days to see what is brewing.
