|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
Fair weather today with variable high clouds. A trough passing by to the north will bring stronger onshore flow and a deeper marine layer Saturday, and perhaps generate light showers Saturday night and Sunday. Fair and seasonal weather Monday through Wednesday, followed a stronger storm that could bring showers late next week
Zonal flow over the lower 48 extends westward over the Pacific all the way to the International Date Line High. This zonal pattern will be in place through early next week with embedded shortwaves over the Pacific passing by to the north from time to time. One of these waves will move inland across California this weekend and deepen the marine layer to 5000 feet by Sunday morning. This may generate a few light showers west of the mountains Saturday night into Sunday. The lifting mechanism is weak so the precip amounts in most areas will be light, with trace amounts to a few hundredths of an inch in most areas, with locally higher amounts of 0.10-0.20". The precipitation will end Sunday afternoon as drier air moves into the lower layers. Mild Monday and Tuesday with scattered to broken high clouds in prevailing moist zonal flow aloft
SYNOPSIS FROM THE PHOENIX OFFICE
Dry weather with seasonably comfortable temperatures will persist through the weekend and into at least the middle of next week. Only periods of passing high clouds will interrupt an otherwise beautiful stretch of early winter weather while no precipitation will affect communities into next week
