Forecast Discussion: Updated Tuesday, April 22, 2014 at 9:50 a.m. A trough will move through the area today and bring breezy conditions and noticeably cooler temperatures for the middle of the week. The PM10 levels will be elevated today as breezy to gusty southwest winds reach speeds of 20-25 mph this afternoon. The ozone levels will be in the good AQI category today due to stronger winds and less favorable wind direction for transport. However Wednesday will be an interesting day from an air quality perspective, cooler temperatures (80s) aren’t usually synonymous with elevated ozone levels. However favorable transport winds from southern California will help bring in ozone precursors which will react with the sunlight to form ozone. So the local ozone levels on Wednesday are expected to be higher (moderate AQI category). Warmer temperatures on Thursday along with continued favorable transport winds will help the ozone levels rise a bit more. Meanwhile the PM10 levels on Wednesday and Thursday will be in the good to low moderate range on the AQI scale. A strong low pressure system will move approach the area on Friday and eventually move through the area on Saturday. Breezy conditions on Friday will help elevate PM10 levels. The strong low will cause a significantly cool down on Saturday with afternoon high temperature only around 80 degrees. Check back on Wednesday for an updated air quality forecast. Forecaster – S.
