FLASH FLOOD...RADAR AND GAUGE INDICATED
EXPECTED RAINFALL...1-2 INCHES IN 2 HOURS

It's really coming down here in Richmond now. Frequent lightning everywhere and already at 1.5" on the rain gauge in the last 45 min or so.

20 degree temperate drop with that outflow that pushed west across Brazoria county.

Almost 4 inches of rain between Mo City and Sugar Land around Austin Pkwy!

Nice outflow breeze now from the boundary as we hit 92-93°F this afternoon. We may see a couple of drops.

Swamp Shack in Kemah.

Reports of flooding all over the area south of I-10.

Wild weather flow. Was moving north earlier today, then West to Southwest. Now kind of north again

Thundering like crazy down in Rosharon.

That was very interesting here in W League City. Almost 3" of rain however the winds were amazing for 1.5 hours. I experienced TS force winds gusting 40-50MPH with the bursts of heavy rains like a feeder bands. Another sign to be ready for the 2020 hurricane season.

The boundary literally split into north and south halves over our house.

Geez, it seems like every time it rains, somebody floods.

Yeah we’re only a few weeks away from the start of the 2020 hurricane season and from what I’m hearing early preparation may be a great idea.Now would be a good time to buy gas for that generator while it’s around a 1.35 a gallon.

Some interesting trends to monitor. Convection to our south and southwest has been persistent. We need to watch and see if it cuts off the inflow for all the activity in west Texas moving east. We will need to get unstable southerly flow re-established overnight if we want decent rain tomorrow. If that doesn’t happen, could be a giant bust.

Stay weather aware tonight

We got half an inch today, but 2 miles down the road they got 2” and then another 3 miles from there they got about 4”. I just took a drive to El Campo to visit my grandma and many streets in EC are flooded. Basically the closer I got to EC, the more it rained.

I don’t really think much will happen. Yesterday and today I think were the days to watch for flooding. The storms just popped up and moved very slowly. Tomorrow all I see is a quick moving squall line that’ll be in and out in one hour or so.

Something to keep an eye on for tomorrow is how the 00z HRRR wraps up that the low tomorrow afternoon just to our north.

Its moving offshore and fizzling out as I type this. Should be z non factor.

Lighting cranking back up in GalCo.
Storms moving in from the west.
