Houston weather: Slight weekend rain chances before heat wave

Houston weather: Your July 18 overnight forecast

This weekend will be a bit of a mixed bag with muggy air and a few storms on Saturday, followed by the start of a heat wave on Sunday.

Tropical disturbance brings rain to Louisiana, Texas

HOUSTON - The tropical disturbance that began near Florida on Monday and tracked across the northern Gulf Coast through the week moved into Louisiana yesterday, bringing heavy downpours. 

Leftover moisture and a weak circulation will most likely help us to see some scattered thunderstorms through tonight. 

We are not under any sort of flood-related advisories, and it doesn't look like it's going to be a huge deal, but plan on seeing some scattered showers and a few storms today. 

Outside of rain and storms, plan on plenty of summer heat and humidity.

Heating up for the weekend

This weekend will be a bit of a mixed bag with muggy air and a few storms on Saturday, followed by the start of a heat wave on Sunday. 

Look for high temperatures in the low 90s on Saturday and in the middle 90s on Sunday when the heat index will rise above 100° for much of the day. 

The rain chance on Saturday is about 30% and then down to 20% on Sunday. 

Beyond that, next week looks mostly dry with lots of sunshine and high temperatures rising into the upper 90s.

Still looking quiet in the tropics

Tropical Weather Update - Gulf disturbance moves across Louisiana

Other than that tropical disturbance we've been tracking this week, there's really nothing else happening across the Gulf, the Caribbean Sea or the Atlantic Ocean, at least not yet. We're still in a time of the hurricane season where it's not at all unusual to have little to no activity, but as we head into the month of August, you can expect that activity to pick up quite a bit. For right now we're still in Saharan dust mode across the tropics and so not much is expected to happen over the next several days.
