DISCUSSION
A SURFACE LOW OFF THE IMMEDIATE COAST HAS DRAWN IN
A PLUME OF MONSOONAL MOISTURE AND IS CREATING AN UNSTABLE
ENVIRONMENT. CHANCES FOR THUNDERSTORMS AND DRY LIGHTNING QUICKLY
LOWER IN NORTHERN MENDOCINO COUNTY AS THE MOISTURE SURGES
NORTHWARD. THE INCREASED INSTABILITY WILL BRING HIGHER MIXING
HEIGHTS THIS AFTERNOON, AND WILL AID IN EFFECTIVE VENTILATION.
THUNDERSTORM ACTIVITY ON SATURDAY IS EXPECTED TO BE LIMITED TO FAR
NORTHEAST TRINITY COUNTY.
