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
SYNOPSIS FROM THE SAN DIEGO OFFICE
Not as hot this weekend with weak offshore flow and high pressure aloft continuing. Coastal low clouds and fog may move a few miles inland each morning. Cooler early next week with more clouds as the marine layer deepens under weak low pressure aloft. A more Fall-like weather pattern is possible for the end of next week as a deeper trough develops along the West Coast.

Skies are mostly clear apart from smoke from the Wildomar Fire. Winds are mostly light under weak offshore flow.

SYNOPSIS FROM THE PHOENIX OFFICE
Expect northerly winds through the lower half of the troposphere through tonight. The exception will be at the surface during the nighttime and morning hours prior to 10:00am where light drainage patterns will be favored. After the inversion breaks, by 10:00am, northerly surface winds will prevail with some areas seeing some gusts of 23 to 28 mph otherwise clear skies.

At 2am (MST) this morning, dry north to northwest flow aloft was present across the state and IR imagery indicated clear skies area-wide. The dry generally northerly flow aloft was a result of the upper ridge axis being centered to our west, and near the west coast. Model guidance is consistent and depicts very little change overall in the weather pattern today through the weekend. Heights aloft are not expected to change much and under generally sunny skies, we can expect high temperatures over the central deserts to remain mostly in the lower range of the 90s today through Sunday
