Forecast Discussion:

The main story this week, as has been much advertised, is the heat. High temperatures are forecast to cruise at or above the 110°F mark today through at least Tuesday, peaking on Sunday just below 120°F. The National Weather Service has an Excessive Heat Warning out for Saturday-Monday, so keep that in mind as you plan your outdoor activities.

In regards to winds, winds near the ground are expected to be generally out of the south through this period. This is good for Yuma's air quality as south winds help to prevent ozone transport from California. However, if any ozone were to drift into Yuma when winds are light over the area, ozone levels should still remain low in Yuma since they have been low in southwest California recently.

Monsoon-wise, there will be a potential for thunderstorm outflow winds to affect the Yuma area overnight or in the early morning hours on Saturday, Sunday, and Monday. Such winds could result in blowing dust and therefore, higher PM10 (dust) levels. But by later Monday, that threat should diminish.
