[Rip76]

Pretty tricky set up.
I'm debating on whether I should head out to League City Village Fair or not.

If I don't, the cells split up right before it gets to Metro Houston.
If I do, I get my new Vans all muddy.

Update from Jeff:

Band of heavy to excessive rainfall slowly approaching NW/W Harris County.

Line of active thunderstorms extends from near Conroe to Waller to Columbus and is slowly moving S to SSE at 10-15mph. Additional storm shave been developing ahead of this line and feeding into the main line. Doppler radar indicates rainfall rates of 1.25 to 2.0 inches over northern Waller County with storm totals upwards of 4.0-5.0 inches over southern Grimes County.

Activity will continue to slowly progress into a greater part of Harris County for the next 1-3 hours. Slow storm motions and cell mergers may result in hourly rainfall rates up to 2.0 inches per hour. While grounds are very dry these type of rainfall rates in urban areas can lead to quick ponding and flooding of low lying areas (roadways) and this will be possible this evening.

Storms should gradually weaken during the evening hours with the loss of daytime heating and portions of SE Harris County may not see much rainfall if the storms weaken prior to reaching that area.

[srainhoutx]

Absolutely pouring here in NW Harris County. Already an inch in the old rain bucket and still storming with a lot of CG lightning.

It got dark and really windy here at about 5:00. The gust front passed by really fast, and so did the main line and heaviest rain as it started to build more to the east. Happens to me every time. I doubt I have an inch so far. I just hope it rains this moderate rain long enough to get me over the 1" mark. We'll see, but at least it is raining and I still hear thunder.

[Rip76]

annnnnnd.... Poof

[Cromagnum]

I've been watering the hell out of my yard all day today. Let's see if I can tempt the fates.

[Kludge]

That didn't last long.

Maybe I should have washed the car.

...

...naaaahhh I can't.

Just too easy.

[vci_guy2003]

The storms fell apart right over houston. Wtf

[jasons2k]

.55" here.

I had .07" for April, and I've had 1.28" in the last 60 days. The last decent rain was .96" on March 9th. The last 1" rain was on Feb 26, and that was exactly 1.00".

7.62" for 2014 so far.

[Ptarmigan]

The storms fell apart right over houston. Wtf

Probably the cooler than normal water of the Gulf of Mexico from the past winter. Generally areas near cooler waters are drier as cooler air from the water holds less moisture. Not always the case. The Aleutian Islands are quite wet due to extratropical storms hitting the area. This also applies to Tierra del Fuego in the Southern Hemisphere.

Also, the dry air from Mexican deserts are a factor. However, storms in South Texas held together.

[BlueJay]

1.09 inches IMBY yesterday! Soooo happy!

8.71 inches so far in 2014.

[MontgomeryCoWx]

1.8 inches at my house yesterday. Not bad
