DISCUSSION

Still mostly southerly wind in the area but sky is getting less cloudy and wind gets weaker. There is a low
probability of rain. All these pointing to a higher ozone today. Clean background and southerly wind will
prevent ozone going higher.

Yesterday's steady southerly brought the pollutants originated from ship channel to the north, preventing a
local build up. The high is at Crosby at NE Houston.
