|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
A fair but cooler day today will be the prelude to a weak storm system moving through Southern California tonight and Saturday. Strong winds in the mountains and deserts are expected afternoons and evenings. Showers will move through the region tonight through Saturday morning. Fair and seasonal weather will follow Sunday through at least Wednesday. Another weak storm system could arrive later in the week for the next chance of showers.
SYNOPSIS FROM THE PHOENIX OFFICE
A Pacific low pressure system and associated front will swing into the western states this weekend resulting in strengthening winds on Friday and especially Saturday. Precipitation chances will be focused across the northern half of Arizona, and will be minimal across the lower deserts. Much cooler temperatures will filter into the region Sunday before another modest warming trend next week. Westerly surface winds will also begin to strengthen this afternoon across southeast California, and become more widespread on Saturday as deep-layer flow increases in concert with the approaching trough. The current forecast calls for sustained wind speeds of 20-25 mph, with gusts of 30-40 mph, on Saturday area-wide. Will have to continue to monitor for the potential for advisory criteria being reached, especially across parts of southeast California.
