Storms are firing again this morning, primarily to the south and east of Interstate 69, where a few areas have already picked up 1.5 inch of rainfall. We’re going to remain in a pattern where there is the potential for storms through the next 12 to 24 hours before higher pressure returns to the area until the weekend.
Tuesday
Overall, our atmosphere should remain moist for pretty much all of today, with precipitable water values of 2 inches or greater, meaning it won’t take too much of a spark to generate showers and thunderstorms. This pattern will allow for the development of on-and-off showers, moving generally to the east-northeast. Unfortunately, storm movement will be fairly slow, which will allow for some areas to see totals of 1 to 3 inches, and some street flooding. Although the rain has developed near the coast this morning, various models show the potential for development at most any location later today. Clouds and intermittent showers should help keep highs in the upper 80s for most of the region.
Wednesday
Pressures begin to build, and this should help to limit storm activity. However, with a still-moist atmosphere, I think at least about 30 percent of Houston should see at least some brief showers. Highs will get into the low- to mid-90s, as some sunshine returns.
