DISCUSSION

Wind is mostly from ESE this morning, relatively strong wind brought in some ozone from other areas and
reached 40s with little production. Yet the morning shower suppressed the ozone and ozone has since been
falling. Forecast has overcast skies, and normal SSE/SE wind in the afternoon. Depending on the cloud, the
region's ozone may come back to 40s-50s in the afternoon.

Yesterday's ozone is generally like predicted. The shower resulted in overall low ozone in the region. The
high ozone spot located at Galveston due to the transport by the ESE wind early evening.
