those cells North of Victoria seem completely determined to get into Grimes county. lol

sea breeze activity maybe?

Crazy how all of the rain has been N, S, E and W of Fort Bend county lol

With 59 closed south of El Campo, I would like to have one or two other options not under water so I can drive back to Houston from Corpus, tomorrow. I have the options planned out. But I'd hate to have to take I-37 to SA to pick up 10.

Looks like the flow from across the border at Brownsville has stopped. And it looks like the blob from Kingsville to Cuero is raining itself out, too.

Gravity Waves?
If you look at the water vapor loop of that MCS interacting with "Bill", you may also notice the gravity wave racing southward "thru" the tropical depression -- seemingly able to propagate as if it's a low frequency radio wave, penetrating every cloud on its journey southward until its finally absorbed into the ridge to the south. So my question of the evening when it comes to "unexpected" forecast features overnight: Will that wave make it SE TX and trigger the tropical moisture to produce "surprise" overnight storms -- something that the models aren't picking up on? (Eye balling it, if it holds together, it wouldn't arrive until after 2am...)

I took a look at the satellite loops of the central U.S. and that is a really neat observation of that wave going right through the low pressure system of Bill! Interesting!

Check out on my Facebook page (link below), the gravity waves originating from Cuba and traveling "against the grain" and free from influence, straight to the Yucatan, where they induced afternoon storms. Fascinating feature. They are pure, low frequency energy.

something's going to collide with the msc coming down from central tx

As if the wave can go through walls, like a ghost. Is there a kryptonite or a speed bump to hinder its travel?

the central tx storm literally "stole the thunder" from it's southern counterpart



previous hour

Cool shot of the lightning... yes, to reply to the previous poster, the "ghost" comparison is good. Gravity waves seems to act by their own rules, immune to clouds or atmospheric flow direction in their trek.

doesn't look to me like it's holding together. But: would this mean severe weather for the overnight period?

I don't think that's what Brooks meant, and what collided with that MCS was an outflow boundary I believe. I still haven't seen the gravity wave Brooks was mentioning but I simply may not know what I'm supposed to be looking for. The MCS in central Texas will not impact our weather

Then the worst we'd get from this "gravity wave" (if it affects SE TX at all) is maybe a little shot of heavy rain, nuby3. (Not a question)

yep, I really don't think there's a high chance of it making an impact, I think he was just making an observation, and posing a hypothesis. if it rains tonight, we'll know why. but more than likely it's gone until the sun comes back out, and normal scattered afternoon showers resume

Back to basics.

A sight for sore eyes for those that have been dealing with flooding, rising rivers and streams and sleepless nights. The San Antonio area is seeing some flooding this morning from the area of thunderstorms that Brooks was mentioning yesterday afternoon and training slow moving thunderstorms have remained almost stationary overnight. The Quantitative Precipitation Forecast for the next week suggests a very typical summer time pattern with heat of the day thunderstorm chances across our Region. The only fly in the ointment will be near the Rio Grande Valley where an inverted trough develops between a building SW United States ridge and the upper ridge across the SE United States. Showers and thunderstorms appear likely throughout the weekend in that area, but drier conditions set up elsewhere.

Rain chances begin to increase by mid next week as a return flow off the Gulf becomes established with a building ridge over the Central United States develops and a rather deep trough organizes to our East. The tropics look quiet across the Atlantic Basin and the Eastern Pacific Basin with no tropical development expected for the next week.
