Forecast Discussion:

A reduction in storm chances through the weekend as the upper levels winds keep mountain storms away from desert locations. Additionally no significant local dust causing activities are expected, therefore have low dust risks forecast for Saturday through Monday. An increase in storm chances early next week, especially Tuesday where outflow winds may be strong enough to cause widespread blowing dust and so have a high dust risk forecast. The chances remain for outflow winds on Wednesday, though at this point they are forecast to be weaker and so have a moderate dust risk forecast.
