DISCUSSION

Same weather pattern continues with a pressure high sitting at central Gulf. Mostly SW wind and very cloudy
skies over whole HGB. Rain chance is in the 40% range. Expect low ozone in the region and high in the
40s-50s. High ozone spot remains to be around Crosby/Baytown.

Yesterday's weather is very similar to Jul 12 except for it is more cloudy. There was almost the same
convergence and stagnation just north of ship channel but the overcast skies depressed ozone production.
Therefore the actual ozone is much lower than forecast.
