DISCUSSION

Today's ozone will be low - cloudy skies, steady southest flows, no coming back ozone like the previous two
days. High will be in NE Houston, like Kingwood or Crosby.

Wind at yesterday's morning was weak NE, it then gradually shifted to east at late morning, southeast at
noon and afternoon. IAH and HOU reported cloudy skies most of the day, but satellite images showed that there
are about 2-3 hours (10-12 LST) that the sky is slightly covered at lower half of Houston. That coincided the
wind shift period and the day's high occured around 10-11 LST at Bayland Park (C53, around Belt 8 and 90).
The high is 112 ppb.
