Tonight’s Forecast:

Tonight will once again be warm and muggy. Overnight lows will only fall to the lower-80s.

Thursday’s Forecast:

There is no relief in sight to our triple digit dangerous heat in Houston. We’ll climb to 103 degrees Thursday afternoon with a heat index of 108-114 degrees. Red flag warnings are in effect for our western cities because of the combination of hot temperatures, low humidity and strong south winds. If a fire starts these conditions make it easy for a fire to spread. Our drought continues to grow with all of SE Texas dry. Our next update to the drought monitor is Thursday.

Extreme Heat & 100 degree days:

The intense heat is not going anywhere. Heat advisories and Excessive Heat Warnings will be extended through the weekend and most likely longer. Thursday is our 47th day this summer with a heat alert, and if we hit 100 degrees it will be our 12th day in a row and 20th of the year. We average 3–100-degree days a year. We haven’t had rain in Houston since July 6th, more than four weeks ago. Avoid burning if you can even in areas not under a burn ban. Conditions are very dry across the board and with no rain expected through the weekend, conditions will get worse.

The other concern we’re watching is how the ERCOT grid is holding during this intense heat. While the entire area is under a Weather Watch, meaning to take care with conserving energy, there is still enough supply for the energy demand in this intense heat.
