Forecast Discussion:

This week, higher pressure will slowly develop over the region today through Wednesday. Then by Thursday, a large pattern of low pressure will begin moving over the U.S. Northwest. A low pressure trough will then eject out of this larger pattern toward Arizona on Friday and move over the state on Saturday. Winds are currently forecast to be lightest during the first half of the week, particularly Wednesday, and then strengthen through the latter half of the week with the more active weather pattern.

Save for the potential for elevated PM-10 levels due to locally dust-producing activities, no issues with PM-10 are anticipated for now. Therefore, the dust risk is Low each day through at least Saturday.
