Did thunderstorms wake you up? A band of rainfall related to a disorganized tropical disturbance moving into South Texas blew through the Houston region this morning, bringing heavy rains and some really loud thunder cracks. This band has weakened now, but a few more storms will rotate through the area today before the westward moving system clears the area. After this we will see mercifully waning rain chances for awhile.
Looking at the radar, a mass of storms associated with the tropical disturbance can be seen moving steadily westward. However, Houston will remain on the northeastern periphery of the disturbance today, so we can expect to see more showers rotate through. Right now we don’t anticipate anything too extreme, but areas that pick up 1 to 2 inches of rain in an hour can probably expect to see some street flooding, which is most likely for areas between downtown Houston and the coast, and southwest of the city.
The National Weather Service has a flash flood watch in place for coastal counties that expires at Noon today. They may extend it through this evening as a precaution. We can probably expect the heaviest rains to die down by this afternoon or this evening.
The main body of the tropical disturbance will push west of the Houston metro area on Saturday, and accordingly rain chances will be best to the southwest of Houston, nearer to the disturbance. However, atmospheric moisture levels will remain quite high across the area, so we may see some short-lived showers and thunderstorms in Houston itself. If you have outdoor plans, you might be OK—just don’t expect too much sunshine and have a plan to duck out of any storms that pop up.
I think this will probably be a nice day. We can’t entirely rule out some scattered showers and thunderstorms, but for the most part we can expect partly sunny skies with highs of around 90 degrees.
This late-summer like pattern will prevail, with highs of around 90, and the possibility of some afternoon showers and thunderstorms. We don’t anticipate anything too extreme, so this should be a good chance for the region to dry out.
Wondering about Isaac? We’ve had countless questions about the former hurricane, which became a tropical storm, which now is a depression. It is probably going to become an open wave. After that time, it most likely will plow into Central America. However, there is a chance it could regenerate and move into the Gulf of Mexico next week. Do we think Texas is a realistic threat? Not really. Are we watching it? Sure. It is mid-September, after all. Should you be concerned? Not right now, and probably never will you have to be.
As for that first cold front, I know we’re all eagerly awaiting that. Unfortunately, I don’t see that much of a chance for one during the next 10 days. During the last week of the month, however, chances for that appear to increase. Hopefully, by early next week, we’ll have a better sense of when things might cool down—just a bit—for the Bayou City.
