Health Message for Wednesday, May 02, 2012: Unusually sensitive people should consider limiting prolonged or heavy exertion outdoors.


Synopsis and Discussion
Models continue to project lower than potential ozone concentration today and Wednesday, perhaps because of the increased mixing related to a developing trough of low pressure to the west.  Though the Valley is not expecting to see gusty winds, other parts of the state may see gusts near 30 mph at times on Wednesday.

Another positive result of the nearby trough is cooler temperatures (if you can call low 90s cool...).  Earlier models were projecting highs pushing towards the triple digits by the end of the week.  Now they have backed off, keeping temps in the low 90s as longs as the persistent trough remains in the vicinity.  We don't expect any major dust issues this week as PM10 levels hold mostly in the Good range of the Air Quality Index (AQI).

Check back tomorrow for the latest.  Until then, have a good day!    -J.Paul
