Potential increases in PM10 concentrations may increase to moderate or unhealthy level.
|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
Weak high pressure aloft will move across Southern California today with a weak upper level low-pressure system moving into California on Wednesday. High temperatures near to slightly above average today and Wednesday. Following will be a weak high pressure aloft with 5 to 10 degrees above average for Thursday and Friday. Lowest temperatures early this morning in the upper deserts will fall into the upper 20s to mid 30s with areas of frost.
For late in the weekend into early next week a trough of low-pressure will move inland along the West Coast. This will bring slow cooling on Saturday with greater cooling for Sunday and Monday.
Overall, mostly weak offshore low-level flow will persist into Friday with locally gusty northeast winds near the coastal foothills and below passes and canyons accompanied by a slow warming trend taking inland high temperature 5 to 10 degrees above average for Thursday and Friday.
SYNOPSIS FROM THE PHOENIX OFFICE
A low-pressure system will leave behind much cooler temperatures for Tuesday with highs in the 70s on the low deserts. Temperatures will warm slightly on Wednesday with little change the rest of the workweek. A stronger low-pressure system will result in increasing cloudiness and precipitation chances across the region during the weekend and into early next week.
