Be Advised
High wind levels have the potential to suspend particulate matter into the air. High levels of PM10 may pose an impact to public health. It is recommended that active children and adults, and people with respiratory disease, such as asthma, limit their outdoor activities.

Potential increases in PM10 concentrations may increase to moderate or unhealthy level.

Imperial County Weather Synopsis
High pressure will build into the region for a significant warming trend beginning today and continuing the end of the work week. Many lower desert locations will warm into the 100 to 105 range Thursday into Saturday. Another Pacific weather system is forecast to move into the western states, mainly north of Arizona, late Sunday and early next week. Although this system will be dry for southern Arizona, it will result in breezy afternoons along with cooler high temperatures

The generally quiet weather pattern will continue for our region into the middle of next week. The marine layer will remain in place west of the mountains...especially near the coast...where low clouds may linger into the late morning and early afternoon. Inland temperatures will increase to 6 to 12 degrees F above normal through Friday...before returning to near normal for this weekend and into early next week.

The upper low located over the Eastern Pacific forecast to gradually accelerate ENE through this weekend...helping to break down the west coast ridge...and then gradually opening up into a wave as it moves across far Northern California on Saturday. Although this system will have little sensible effect on SoCal weather will help to deepen the marine layer substantially for the weekend...and diurnally-driven gusty westerly winds across the mountains and deserts will also be possible at times
