The storms that dumped 20" to the south of us didn't get going until after 10 last night, really blowing up after midnight. Impossible to pinpoint where another one of those could form later, just don't let your guard down. The atmosphere will become destabilized with sunshine starting to peak through and ample moisture should spark at least some scattered storms later this afternoon.

There remains a ton of deep tropical moisture in place across SE Texas and additional moisture streaming inland off the Gulf in the low level flow. As the airmass destabilizes this late this afternoon, additional showers and storms may develop. Then we still have to consider nocturnal tightening of storms near the circulation and additional feeder bands organizing just like they did around 3 to 4AM this morning. Those feeder bands can develop well S and W of the circulation. We will see how it plays out by the end of the day tomorrow. To add to Belmer's post, I've actually seen some peaks of sunshine a couple of brief moments up here in NW Harris County this afternoon. The atmosphere up here is very tropical and juicy right now.

We're starting to see some wrap-around mini showers as the center moves NNW on the eastern shore of Lake Livingston.

We have a pinwheel-like line of showers developing from Marlin to Conroe.

I am afraid it is far from over for your area. You may be in the 20" department by tomorrow evening.

Yeah the ‘Conroe band’ stops just a couple of miles north of me. It is an intense one.

As others have pointed out, things could get interesting again overnight. I think a lot will depend on how far west the center can move (I sound like a broken record) but it will be feast or famine again, but possibly for different people.

18z HRRR wants to fire up storms around rush hour in southeast harris county and then really hammers the metro area late night into tomorrow morning. HRRR has been rather consistent in firing up a band around 4 or 5 pm. We are getting close to that time and radar is showing a few hints of showers popping south of town.

18z NAM 3km is starting to roll in. Not sure if there is an initialization problem or not but the first couple of hours are missing data it looks like.

Seeing some storms spin up around Katy, being dragged east along I-10. Let's see if they fill in...

Well wouldn’t you know, there’s actually storms firing up sw of Houston. Not much, but I’ll take it.

I'd be extremely happy if we could manage to get in on the action even just a little bit this evening/tonight here in Cypress! Sun is out and it is steamy so hopefully that will help. Sitting at .40" to this point. However, I don't want to see the areas already hit hard get pummeled again by any means though.

We are hoping the same here in Fairfield. We got 2" last week which was nice but are sitting at about 0.2" right now from Imelda. Looks like the broken feeder band is pulling through south of us right now so we may have to hope the one near Navasota fires up and eases south.

The WPC is suggesting we need to keep an eye on tomorrow. That Moderate Risk of Excessive Rainfall includes all of Harris and Montgomery Counties. The sun is shining brightly in NW Harris County now...which is worrisome. I see several distinct bands of thunderstorms continuing to organize. And for my backyard rainfall, I emptied .70 out of the gauge at 7 AM this morning.
