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
High pressure will bring warmer and dryer weather for the next few days. The marine layer will diminish and coastal clouds will be less extensive. A trough of low pressure will bring a gradual cooling trend for the latter half of this week. Cooler weather and more coastal clouds are expected for the holiday weekend

High pressure aloft will strengthen today over Southern California, bringing a warming trend for all areas through Tuesday, though less pronounced near the coast. Temperatures will rise into the upper 80s to low 90s for the southern valleys, 100s for much of the Inland Empire, and approach 110 in the lower deserts today. Tuesday still looks to be the warmest days, with temperatures a few degrees warmer than today. While the warm-up will be noticeable, afternoon highs will only be a few degrees above normal for this time of year at most locations, with record highs reasonably safe from being broken. The Inland Empire, however, will be around 5-10 degrees above normal

SYNOPSIS FROM THE PHOENIX OFFICE
A sharp warming trend is expected today across the region. Moisture will return across eastern Arizona during the middle of the week with higher humidity values building steadily westward across the area. Afternoon thunderstorm activity initially confined to the eastern Arizona mountains will likely affect the lower deserts mid to late week. A drying trend is then likely through the weekend as a low pressure system moves through the western states
