HOUSTON — KHOU 11 Chief Meteorologist David Paul says temperatures will be dangerously high this weekend and we could reach the 100 degree mark for the first time this year.

We are under a significant hot spell due to a high pressure system that is sitting on top of us. Triple digit temps are expected Saturday through Monday. Overnight temps will stay near the 80s.

The heat index will reach 110 degrees in some parts of the state. A heat advisory is in effect for the entire Houston area from noon until 8 p.m.

The next chance for rain won't come until next Tuesday. That could break the heat wave in some places, Paul says.

Make sure you are using your hot weather precautions. Drink plenty of water, stay indoors as much as possible and don't forget to triple check those backseats.
