Of Note:
As you've probably heard, today a slow-moving front (unusual for July) is teaming with Gulf moisture to form a slow-moving line of heavy rain from NW→SE. Right now northern Hill Country is getting hammered - some parts of San Saba/Lampasas Cos. have gotten over 6" of rain since midnight. This is all moving SE and unfortunately should affect the Kerr/Upper Guadalupe area later this morning/early afternoon. I don't think any floods will be huge/catastrophic (can it be anyway after last week? How much more is "catastrophic?"), but could cause evacs and issues.

ATX will also get a good amount of rain out of this it looks like - easily 2" upward and more in some spots until this passes through. Very possible that main streams/creeks (Shoal? Onion?) and low-lying areas could see some flash and/or minor flooding. Be alert today. NWS has had flood watches posted since early Sat. a.m. for this, now a series of flash flood warnings for upper Hill Country, will almost certainly be extended this way (unfortunately) if rain keeps up. It could lessen by the time it hits over ATX but with all the moisture in our ground/air I don't think so.

I haven't had time to look at the weather background, but this is a July reminiscent of 2007. The big summer highs have stayed away - it's possible the huge tropical situation we've had the last 2 weeks has and will impact our weather more this summer. The mid-upper air patterns aren't typical for us, but why/how long, if I look through it I might get a better idea. Like I said, although this front is "cool" (i.e. not changing temps much) it's still a front in July, so that's not usual. Two-week outlook calls for rain to stop and July to come back (hot dry) but that was supposed to happen now - and well, it's not at least this weekend, another "slight" rain forecast expanding to "heavy rain". But it happens.

Meantime, heed warnings, watches.

I've had that same thought several times. But I don't remember flooding that summer, just constant rain.

Yeah Lampasas got a whole bunch of rain. It flooded Sulphur Creek and the annual Spring Ho festival. They put a bunch of booths at the park and I saw some pictures of the water. Probably damaged a lot of stuff for vendors that left their things out overnight.

The last time I remember Lampasas getting rain like this I was maybe 10 or so and the road by our house on CR1020 that took us into town went from a small creek to a river-sized body of water that was about 150 yards across at least. Never forget seeing all that water go up so quickly.

That was the year of the rain bomb around Marble Falls - June 27 (19"). There was significant flooding, but the only reason why it wasn't worse is that it was so close to the lake the flooded area was a relatively short distance. I think I had about 7" out of that system in W. Travis.

But yeah, it also was just a rainy summer, I believe 100° temps were never achieved - or very few of them. In fact I don't think it got above 90° until July. Something like that.

Called my mom to see how they were doing. They never get flooded where she lives because the house is on the high ground just outside of Lampasas on CR 1020. However, she did say that the electricity has been out since 2:30 this morning. Pedernales is usually faster about getting it restored so they must be having some bigger issues right now. I’m honestly surprised Lampasas doesn’t have more flood issues since the town is bowl shaped. That it has been almost 70 years since the big flood in 1957 seems like they are overdue for a big one.

LCRA has dropped Lake LBJ over 1.5' in the last 12 hours. That's more than they dropped it on the 4th. Wonder if they are planning on starting to release water from Buchanan.

Rain, imo.

Agreed - the Llano is flooding again, and I suspect they don't want a repeat of getting behind the inflows.

Update:
Well at least this thing has a shape - and it's a pretty common "frontal curve" line. It's moving through the immediate ATX area now. Behind it the rain is lighter and not as intense, though it's a big blob of it, but it's more moderate. Point: I think most of the worst of the rain will soon pass then light/moderate rain up through dinner.

If stuff regenerates behind it and causes further potential consequences I'll be back. Otherwise I think this is the worst of the day (fingers crossed) as this frontal thing s-l-o-w-l-y creeps through our region.

If it's any consolation, rain has ended in the Upper Guadalupe Valley - looks like for a good while if not for good with this. I'll be back if not.

Yeah, they took a lot of flack last week for waiting to long to lower LBJ. I think (hope?) they are being over cautious this week.
