Model Forecast Updated on 8/3/2007 7:45:41 AM. Previous Forecast in Parenthesis.



Model gave a high ozone forecast based on the NW wind and less cloudy skies. The uncertainty here is the
cloud - it appears to be more cloudy than the weather forecast, so the high may not reach the exceedance
level. With NW wind, high is likely to be in the S/SW part of the city.

Yesterday's rain and cloudy skies meant ozone won't go too high. Weather forecast was not as cloudy in the
morning and noon. Its wind pattern was also very inorganized - light and variable N/NW wind brough moderate
ozone to the Brazoria and Galveston. The high, though, was at ship channel at 2-3 LST.
