Another round of pop-up storms Tuesday, Saharan haze arrives Thursday

HOUSTON, Texas (KTRK) -- We'll all get another chance to win the rain lottery on Tuesday when more pop-up showers and thunderstorms develop in the afternoon heat. Rain chances drop to near zero by Thursday as Saharan dust returns to Southeast Texas, but those daily downpours are back by the weekend.

Tuesday will be another hot and steamy one with morning lows in the upper 70s and afternoon highs climbing into the mid 90s under a partly cloudy sky. The afternoon heat index will range between 101 to 107 degrees. Once again there's about a 30% chance for a shower or thunderstorm to impact parts of Southeast Texas, mainly in the afternoon and early evening. These storms could bring briefly heavy rainfall, wind gusts over 40 mph, small hail, and frequent lightning.

When does the Saharan haze impact us?

The next cloud of Saharan dust starts arriving late Wednesday, peaks on Thursday, and lingers into the weekend.

What is the weekend weather outlook?

We'll still have some Saharan haze around this weekend, but there's also a surge of Gulf moisture arriving to boost rain chances both Saturday and Sunday. We expect lows in the upper 70s, highs in the mid 90s, and a 40% chance of scattered thunderstorms each afternoon.
