Again much like yesterday; winds same direction but slightly stronger, but background levels (judging from Galveston obs) are slightly higher, over 60 ppb. Winds are currently from the west just about everywhere, so the Houston nighttime plume is probably not over the Bay. Winds will develop from the south during late morning, bay breeze will develop along the coast by noon or so, and gradually move inland during the afternoon. By evening winds will be from the south at about 10 kts everywhere. Exceedances of 130-150 ppb seem likely, especially north of the ship channel and north of downtown. High ozone is also likely in Beaumont (lighter winds and possibly dirtier air) and Tyler/Longview (Houston plume; 88 ppb at 1 AM today)

Max T near 100 F (39 C) Clouds few or none

Same general pattern; ozone should not be much different unless background levels change.

High pressure will remain over the area until Monday. A ridge building over the southeastern US will bring unsettled weather with possible widespread showers Mon-Wed, with Tuesday looking wettest at this point. The latter part of next week will be a different regime, with less subsidence and flow either from the East Coast or from the Gulf of Mexico and subtopical Atlantic.
