What are the chances this storm comes ashore on the upper texas coast rather than lower to mid?

Remember, most storms are notorious for marking its first landfall with models then does the infamous shift eastward as days go on... We will see.

Not a drop so far... and the forecast as of this message is 70% likely rain for this afternoon/evening. Current radar says no-way. I'm not blaming the local NWS folks, just the models they rely on. How can they miss so bigly?
Same here. Another day. Another bust. Sprinklers on stun.

Euro Gone Wild on the long-term precip. 2.5 inches to 6 to 14 inches from Houston to the Hill Country, particularly related to 91L and 99L over the next 10 days. 1-3 inches on the other models. Maybe.

0z ICON model is coming in a good bit stronger and slower too. Definitely a tropical storm.

Some of the short range models develop precipitation around the Houston metro area overnight. We shall see...

Got 3 inches over the last 24 hours here by Clear Lake. Not going to be greedy, only going to ask for another 6 inches from 91L.

My hunch is recon will fly out there today. Looking at visible this morning there is clearly low level convergence in all four quadrants under the deep convection that is bubbling up right now. Looks like the 'center' is developing around 87W 25N.

Be interesting to see how well it can maintain this convection throughout the day or if it will wane off.

Lots of rain down to the SW this morning. I guess today I’m too far east 🙄

It’s looking like the models for 91L have most of the rain concentrated right along the center and just south of the center when it comes ashore later this week..that could be a bad thing if you’re wanting rain. It’s looking like areas north of 10 might be lucky to get 1-2” out of this. Jackpot seems to be from the Victotria area down towards Corpus Christi as of right now.

QPF will largely depend on how Invest 91L gets its act together and location of landfall. Though with SETX likely being on the eastern side of this system, heavy rainfall and even flooding is possible. WPC increasing rainfall totals - mainly just offshore. Where the training feeder bands set up will be the areas that will have the greatest flood threat. Even after 91L moves inland, high PW's with a strong southerly moisture feed will still be funneled right in our area as 91L moves west near the RGV.

Parts of Beaumont and Port Arthur saw 4-5 inches yesterday, much of that falling late afternoon into the evening as a convergence zone set up over the area from the remnants of the low that moved into the Victoria area a few days ago. That will be something we will need to watch for as we head into Saturday-Monday.

Im getting nervous about qpf covering the beaumont Port Arthur area more and more each day. Weve had 4-5” of rain here since yesterday and so far qpf has us for another 4-5” when the storm approaches. Which is manageable, but if it keeps climbing, I think once again we will be in trouble. Maybe not another Harvey but possibly another Imelda situation here. Just proves that you dont need a direct hit from a storm foe it to reak havoc. Keeping a close eye on this one. Time will only tell...

U model watch to much, look at the pattern, look at the total environment and ingredients in place, if it develops info trop Storm u will see more totals.

Yeah I agree it's a little too early to put too much stock in QPF amounts and locations. How organized and the size of 91L will have impacts on QPF amounts. Remember that low resolution models can often underestimate rainfall amounts when it comes to tropical rains. With southeast Texas most likely being on the dirty side,don't sleep on the potential for flooding regardless of the QPF the models are showing.
