Forecast Discussion:

Over the next week, the jet stream will generally remain over the Southwest/Mountain West. This will ultimately prevent any strong high pressure some setting up over the regions. Instead, various low pressure waves will move through. One such wave will begin to approach the northern coast of California on Sunday and slowly expand into the Southwest on Monday and Tuesday.

Weather-wise, high temperatures are forecast to continue in the 80s through at least Sunday, before dropping back into the upper 70s again by Monday because of the said low pressure wave. Skies will also remain mostly sunny during this time, with perhaps a slight increase in clouds on Saturday. Afternoon breezes are expected most days, with winds looking to be lightest on Saturday. Monday is forecast to have the strongest winds, out of the south-southwest.

Dust-wise, stagnant morning conditions will be favorable for the build-up of locally produced dust. And perhaps we can't rule out some pockets of dust on Monday with the winds. But overall, the dust risk will stay Low for now.
