Houston weather: Another scorcher on the way for Wednesday

We got within a few degrees of record highs on Tuesday and we'll come close again Wednesday as we head toward 100. Much of the country is under heat advisories or extreme heat warnings, so widespread dangerous heat will continue impacting over 150 million people nationwide. We are not under any advisories because our overnight temps and even hot afternoon highs are below those warning criteria. However, we are under an air quality alert for higher ozone levels. So please limit time outside if you do have any respiratory issues. A gradual increase in rain with a good chance for showers and storms Friday through Sunday will cool things off a bit.
