Yes, it's hot, but there's a chance for heat-relieving showers later this week

HOUSTON, Texas (KTRK) -- Record highs will be challenged later this week as a sprawling dome of heat presses on Texas, but we do have a chance for heat-relieving showers by the weekend. Until then, it's mostly dry with the humidity and heat combo flirting with dangerous levels.

Tuesday afternoon brings more bright sunshine under a partly cloudy sky. The sunshine will help temperatures rise quickly into the mid-upper 90s with an afternoon heat index as high as 110 degrees expected. A Heat Advisory has been issued for all of Southeast Texas until 7 p.m. Tuesday.

How hot will it get this week?

We expect a few days this week with triple digit heat thanks to that summertime heat dome. Morning lows temperatures will still be in the upper 70s, giving us some time to enjoy the day before the true heat sets in during the afternoon. But by the latter portions of the week, morning lows will be in the low 80s.

When will the rain chance return?

A summer cool front will get close enough to us by the weekend to warrant at least a 20-30% chance of rain Saturday and 40% on Sunday. There's also the chance a few showers and storms could be on the strong side, especially Saturday night. And while that front may not bring a refreshing cool down, it could help keep a daily rain chance in the forecast next week as temperatures dip back closer to their seasonal range for the first week of August.
