small geographic area, but a large population that is worried

Yes, indeed. I read the mesoscale discussion - the 20% of watch issuance was a shocker to me as there were already right-turning supercells feeding off that inflow headed right into the metro area. They have issued small watch boxes before given the situation - this was one that warranted it.

Certainly understand and I just wanted to explain to those interested what I believed the reasoning was for not issuing a Watch. No disrespect intended toward you or Jason what so ever. We have a very knowledgeable and unique group weather folk and I appreciate you ALL...

Jeff says the Fort Bend cell is a 'classic' supercell. Approaching Needville at 3:43.

The Waller county cell he referenced is a 'hyper-producing supercell' feeding off the boundary from last night. Upper part of Spring Creek around Hegar Road is a concern for excess water.

He was chatting live with Frank on channel 2.

Watching the Montgomery/N Harris Counties cell closely. Looks like it is cycling back up. That's been the history of these super cells all day. Cycle up then cycle down.

[txbear]

that fort bend cell really had the classic hook that you see up in OK/KS, N TX and the Panhandle. the velocity signature was really bright, which you hope wasn't a debris ball.

definitely has been that way all day - it's like a Nintendo game monster that you thought you killed, then it split into 3 monsters ! (just to give a perspective to the younger crowd )

Gotta keep an eye on the southern and SW flank of that storm.

That SW storm finally pissed itself out.

[srainhoutx]

Flash Flood Watch coming shortly for areas along and N of the I-10 Corridor. It will include Harris County, but not include Wharton and Ft Bend as well as the Coastal tier of Counties. Current thinking is a general 1- 2 inches possible overnight into tomorrow with some 3 to 4 inch amounts possible in training slow moving storms.

Storms are beginning to fire over the Mexico Mountains to the West of the Rio Grande River and upscale growth is expected to increase and expand with the evening hours. PW's are running high at just below 2 inches and radar estimates today have been less than actually what fell.

[srainhoutx]

Update from Jeff:

Flash Flood Watch is being issued for SE TX for tonight along and N of I-10.

Heavy rainfall over the last few days and again this afternoon has resulted in saturating ground conditions. Air mass will begin to recover from the current round of storms and as another strong disturbance approaches tonight a new complex of thunderstorms with heavy rainfall will likely develop over SW/SC TX and move toward the area.

Additional rainfall amounts of 1-2 inches with isolated totals of 3-4 inches will be possible with this next round or storms. Most Harris County watersheds will be able to handle this amount of rainfall. However, increasing run-off from both rainfall today and yesterday into the San Jacinto River (west and east forks) as well as Spring Creek and Willow Creeks in N Harris County needs to be monitored.

Main threat from high rainfall rates both this afternoon and tonight will be street flooding.

Update:
Spring Creek at Hegar Rd has risen to 3ft below bankfull and will continue to rise. Minor low land flooding on rural lands near the creek from the headwaters to Hegar Rd is possible this evening. Additionally, low bridges crossing the creek could be impacted.
