Folks,

It is literally night time here in Gulfgate. It is that dark. It is that dark. I have never ever seen it this dark at 10:34 am in my 8 years of working here. Incredible.

Nearing 2 inch an hour rainfall rates in Western Harris County

See that .08" from the guage at I-45 & The Hardy? Yep...that's pretty much me. The outflow just exploded off to my south and east, leaving me with just a few showers. Looks like only a small portion of NW Harris into Montgomery County was left out of the fun (so far).

Raining harder now here in NW Harris County. I had a 10th of an inch early this morning before the complex moved in.

Wow! I just got home. Was hoping to get my errands done, but did not quite make it. I ditched the last one and headed for home. That short trek was really scarey. Roads were already starting to pond and it had only been raining for about 10-15 minutes.

[jabcwb2]

Hi all,

Are we in for much more rain today? I need to either keep office open or shut her down for the day so people can get safely home. Office is located in Galleria and employees live as far north as the woodlands, Katy and southesat harris county.

Thanks!!!!!!!

I received 3 inches of rain overnight - at work now in downtown and it was dark as night here with rain coming down in sheets.

Looking like more forming back to the west - will it make it to SE Texas - will be the big question. Wet and soggy Friday and looks like again for tomorrow.

[spadilly]

well...that was fun. wow

I guess now we just wait and see if the atmosphere re-energizes in time for the next wave to come through.

We will have to wait and see. Sun is poking out here in College Station and temps are starting to heat up but the atmosphere has been worked over pretty efficiently. The next "band of storms" (if we get another one) that come through probably won't be as strong but you never know.

[Texas Pirate]

2" of rain in the bay area where I live.

[mckinne63]

We better get some more rain or dh is going to make me eat crow for making him cancel the mulch

I measured another 2.93" today, about half early morning and the rest around mid day. Total 20.4" for the year.

[spadilly]

Several warnings out west already.

[Paul Robison]

Well, the latest HRRR model runs appear to show a credible scenario for tonight with an area of showers and thundertstorms moving through the region after midnight and into the morning hours. The lower levels of the atmosphere took a pretty good wallop after all that severe weather we had this morning so I personally am not as worried about severe weather as I am about minor flooding given the huge amount of rain we had in the last 24 hours. Now, if you live in the costal counties, you might see daytime activity akin to what we Houstonians saw today as the surface boundary moves through the region.


How did I do, folks? Anybody agree with me?
