Rain? You Don't Say

Tomorrow the Valley of the Sun has a 30% chance of rain.
Forecast Discussion: Low pressure to the west will spin in place through much of the week. The southwest-to-northeast flow will keep the potential ozone and precursor train from southern California moving into Arizona. The good news is that smoke from southern California wildfires won't be much of an influence as crews have mostly subdued them. Local ozone levels continue to decrease steadily with highest levels in the lower Moderate range. With the churning trough of low pressure to the west, Arizona can expect gusty winds Tuesday and Wednesday. This could cause localized pockets of dust in the vicinity of recently disturbed soil. Overall maximum PM10 levels, however, should remain mostly in the Good range. Conditions improve Thursday as winds decrease.
