That number is going to go up too. Seems like everything coming out of the gulf has roation currently, if most kinda broad currently.

01z HRRR is running now. Some parts of Houston forecasted to get 9 inches over the next 5 hours.

Boy, that radar sure looks like it's moving due east.

I don't believe that map. Coming back over the I-35 corridor and dumping copious amounts of rain on wed. and then circling back with the same on thursday. Please. These long term maps are ridiculous.

Thanks for posting though. It's appreciated.

Legit question here...and apologies in advance if the answer is too obvious...but why wouldn't the system eventually "rain itself out" after a few days and just dry up? Is the simple answer because a lot of the storm is still somewhat over the gulf?

Just think about where it is, and the direction of the circulation.

Air goes from higher to lower pressure, eventually looking to equilibrate. So it's going to keep pulling in air. The roation is counter clockwise. So it's going to continue to pull mosit gulf air toward it. It's not storing the mositure so much as continuously pulling it toward the center.

It just keeps pulling moisture from the gulf. As Duke mentioned, the flow around the low is still counter-clockwise, and will remain that way regardless of the strength.



You can see how it is pulling water for hundreds of miles to the south.

NWS Houston office.

If anyone reading this is in the Houston area, check weather.gov for Houston and check it often.

Weather has been calm all day, but it's starting to get ugly out there.

To take it a step further, it is "raining itself out" on basically the entire SW side. Houston is just in the crosshairs of the moisture being pulled right off the GOM. None of it is really making its way around the entire circulation that is over land.

I'm afraid our little mini vacation is over. At least we got enough of a break to let the boat canals settle back to semi-normal levels.
