Indeed. The radar signal seems to show a bit of circulation there, with the center somewhere around, or shoreward of Beaumont.
There was some circulation yesterday as well.

Pinwheel shower are rotating around a diffuse center and underneath the ridge. Hope we see a few. Just missed out on a line that is becoming more robust.

A bigger stunner -we have not reached 90°F yet. A nice change!

Most of the models are ejecting the system quicker and reducing the western movement late this week. If that scenario plays out most of the precipitation will stay east of the region over Louisiana. Something to continue to monitor but the current trend is a good one.

...FLASH FLOOD WATCH IN EFFECT FROM MIDNIGHT CDT TONIGHT THROUGH
MONDAY EVENING...

The National Weather Service in Houston/Galveston has issued a

* Flash Flood Watch for a portion of southeast Texas...including
the following counties...Brazoria Islands...Chambers...Coastal
Brazoria...Coastal Galveston...Coastal Harris...Coastal
Matagorda...Fort Bend...Galveston Island and Bolivar
Peninsula...Inland Brazoria...Inland Galveston...Inland
Harris...Inland Matagorda...Matagorda Islands...Montgomery...
Northern Liberty...Polk...San Jacinto and Southern Liberty.

* From midnight CDT tonight through Monday evening

* Slow moving thunderstorms are expected to develop over the watch
area producing periods of heavy rainfall. Deep tropical moisture
will spread over the region tonight and Monday fueling the
development of storms beginning around midnight. These storms
will be capable of 2 to 3 inch per hour rainfall rates given the
moist environment and slow movement. Rainfall totals of 1 to 3
inches can be expected with isolated totals of 5 to 6 inches.
Some areas that received moderate to heavy rainfall today will
be more prone to runoff and street flooding. The storms should
weaken by late Labor Day afternoon.

* Primary impacts will likely be street flooding and low water
crossings. Minor flooding is possible of streams and bayous in
the area though any flooding would likely be limited to just the
smaller watersheds.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

Whew! Dont need too much rain from 7. An eastern landfall woul be best for us but bad for them. Any chance it continues an eastern shift or a more western shift? Thoughts? I though the high was supposed to block it from going nortward and send more on a western track. Ensembles still show a southern Louisiana into setx. Track is now eastern Louisiana into northern Louisiana and onward north. Im confused.

I think the current track is going to verify pretty nicely. A lot of the models that were showing a strong west shift have adjusted further east. For instance, the ECMWF ensembles for the most part shifted a good bit east with a less west bend after landfall. .

I used to gripe about the NWS and modeling, etc.

But after Harvey, I’ll lean with what they have to say.

I’m not expecting much of anything here in SETX from the storm. We’ll be on the dry side.
