Heat and isolated storms this weekend
Another round of hit-or-miss thunderstorms will push through Southeast Texas Saturday. It'll be super hot as well.

HOUSTON, Texas (KTRK) -- Temperatures Saturday afternoon were close to the triple digits! And it's going to be hot once again for Sunday but with the chance for a few more isolated storms in the afternoon.

Temperatures Saturday evening will fall into upper 70s by Sunday morning. Sunday will start off sunny as clouds build through the day. There's a 30% chance for a passing shower or storm as the sea breeze pushes in from the coast. High temperatures will vary depending on if you get rain or not, but most of Southeast Texas will likely warm into the mid 90s Sunday afternoon. So expect another hot day!

What should we expect if we're going to the opening game at Reliant Stadium Sunday?

Stay hydrated and wear sunscreen! It's going to go from a warm, humid morning to hot afternoon pretty quickly Sunday. Temperatures in the morning will quickly climb through the 80s to be near 90 degrees at kickoff. Heat index values through the morning could reach as high as 99 as the temperature climbs too. During the game we'll see a few isolated storms develop with the sea breeze. and depending on their timing, a few storms could be near the stadium in the afternoon after the game. Otherwise, we'll have a mix of sunshine and cloud cover after the game with temperatures in the low-mid 90s depending on if there's rain near the stadium or not.

Are you seeing any signs of a fall front coming this way?

We do have a weak front reaching Houston about 8 days from now on Sunday, September 20th. It's too soon to know if this front will have enough strength to push all the way through and bring us lower humidity or cooler temps. Regardless, the front should at least bring a chance of rain.

What are you tracking in the tropics?

Norbert has formed in the Pacific, meanwhile the Atlantic remains quiet here at the peak of hurricane season as El Nino remains the strongest on record for this time of year. For a more in-depth discussion on what's happening in the tropics, visit our Daily Tropical Update page.
