HOUSTON – High heat and a chance for severe afternoon thunderstorms are giving some of us a double dose of dangerous weather conditions for Tuesday, according to KHOU 11 News Meteorologist David Paul.

Tuesday kicked off with lows in the 80s and highs are expected to top off around 103 degrees. The heat index, however, is going to make it feel as hot as 110 degrees outside.
Some neighborhoods could see a thunderstorm while others will be left to deal with the extreme heat.
“There is a disturbance that is heading southwest and it enters the Houston area as we head toward maximum daytime heating today so dangerous heat, and some of these storms that pop up this afternoon could be dangerous with damaging straight line winds as a severe weather,” Paul explained. “So an interesting day; everyone gets the heat and then some of us could see a severe thunderstorm late in the afternoon.”
In an effort to not overload the power grid, ERCOT is asking consumers to conserve energy between 3 and 7 p.m.
The extended forecast shows the heat wave will break on Thursday, dropping highs back into the 90s and temperatures are expected to remain in the double digits—with a slight rain chance—this weekend.
KHOU 11 News is still keeping an eye on Tropical Storm Debby.
Parts of the main interstate highway across northern Florida were closed by flooding Tuesday as Debby hung stubbornly offshore over the Gulf of Mexico, threatening up to two feet of rain in places.
After raking Florida’s Gulf coast with high winds and heavy rain, Debby promised to bring more of the same in the coming days as it drifted on a path forecast to take it over the state and east into the Atlantic by Friday.
The National Hurricane Center said Debby was about 85 miles west of Cedar Key, Fla., and moving eastward near 3 mph. It had maximum sustained winds near 45 mph, barely tropical-storm status.
But the wind, high surf and relentless rain have made the storm’s presence felt.
