HOUSTON, Texas (KTRK) — Rain chances are on the rise as we head into the holiday weekend, and you’ll want to draw up some indoor options in case your outdoor plans get rained out.
A deep surge of tropical moisture arrives from the Gulf on Saturday, and as it gets lifted by an upper low over Texas, slow-moving downpours will develop in a widespread fashion during the afternoon. These thunderstorms could drop up to 3″ of rain in just an hour and lead to street flooding. Frequent lightning could also knock out the power. Temperatures will be kept down by the thunderstorms with highs only in the mid 80s. Once the storms begin, temperatures will cool off into the 70s.
Will the entire holiday weekend be a washout?
No, but there is washout potential at times, especially on Saturday afternoon. If you have outdoor plans, it would be wise to draw up a “plan B” in case the weather rains them out. Sunday’s rain chance hinges on how the storms develop on Saturday, and there is a chance it will turn out mostly dry inland with the rains confined mostly to the coastal counties throughout the day. Labor Day will be similar with high rain chances in the coastal counties and lesser rain chances farther inland.
How much rain could we get?
Rainfall totals over the next 7 days will generally range from 1-4″ north of I-10 and 4-6″ south of I-10. There will be locally higher amounts, especially near the coast, and street flooding is possible.
What’s happening in the tropics?
Hurricane Danielle is now spinning in the North Atlantic, but we’re keeping a closer eye on a tropical system developing over the Pacific Ocean south of Mexico. It will be a wild card in our rain chances for next week. For the very latest check out our daily tropical update.
