[Rip76]

The line is moving along up here.
Looks like training will setup towards the Southwest tonight down towards Matagorda, Bay City, Port Lavaca areas.

Yep

My street is flooding right now here in the Heights.... Remember this is a multi day event and the forecast is likely to change quickly due to the mesoscale driven nature of the event. For example the storms moving through now were not even forcasted by most models as late as this morning....Like the last few days we really won't know how tomorrow will play out until,tomorrow. And that will be the case through Friday.

[tireman4]

Really kicking up a fuss in Humble

[Cromagnum]

Southwest part of viewing area gonna take a bath tonight.

[Texashawk]

Just lost power in Sienna

[cureduchenne]

I am in Jackson county, southern portion, and the rain has been heavy for awhile now. We got plenty of rain Sunday so won’t take much to flood.

[Cpv17]

Picked up 4” tonight bringing my total up to 6.50” since Sunday. Still raining steadily out there.

[djmike]

Just hit Beaumont. Waaaaaaay sooner than expected. Sheets of heavy rain. Neighborhood is flooded again! No real wind gusts so thats good. Lightning is pretty intense. Besides flooding right now, no damage that Im aware of thank goodness. Stay safe everyone.

[djmike]

This is getting old in Beaumont.

Beaumont May 2021 Flood

[don]

Very impressive that there is still plenty of convection around, after the heavy rain last night still getting rumbles of thunder also.We need to keep an eye on the disturbance this afternoon coming out of Mexico at the moment.

[jasons2k]

One of the longest, maybe the longest lightning show I’ve ever seen.
1.16” before midnight
1.00” since midnight
Still a steady shower here...

[djmike]

When is the next system? Afternoon? Evening? Overnight? Fence damage and want to try repairing before the next round.

[Cromagnum]

2.6 inches overnight here and still raining, though not nearly as hard

[don]

Alot of what will determine the strength of the storms later today will be by how quick the storms in the gulf dissipate. And allow a return flow of moisture from the gulf.If the storms take their time to dissipate the system later today will be weaker once it enters the area.If they dissipate quicker the storms later will have the potential to be stronger with a heavy rain threat. Like the last few days we will have to watch trends on the radar and mesoscale models today.

I dunno. It's rampaging down in Matagorda Bay right now.

[jasons2k]

No updates this AM from the local Mets.
I think there’s a lot of uncertainty about the rest of today which will obviously affect how tonight/tomorrow goes. Nobody is ready to walk the plank just yet - probably wait and see for a couple more hours.
I think the fact that the MCS pushed so far south and held together out in the Gulf threw a curveball.

[Texashawk]

It looks like an absolute maelstrom in South Texas. Is that our future if the stuff in the Gulf dissipates, I wonder?
