...THUNDERSTORMS MONDAY COULD BRING DRY LIGHTNING...

A LOW PRESSURE SYSTEM OFF THE COAST WILL BRING MID-LEVEL MOISTURE
AND INSTABILITY FROM THE SOUTH ON MONDAY. THIS WILL CREATE A
CHANCE OF THUNDERSTORMS MONDAY THROUGH TUESDAY. THE LOWER LAYERS
OF THE ATMOSPHERE WILL REMAIN VERY DRY MONDAY AND WILL CONTRIBUTE
TO A THREAT OF DRY LIGHTNING. DUE TO THE STRENGTH OF THE LOW
PRESSURE SYSTEM...THERE COULD BE FREQUENT DRY LIGHTNING FROM THE
MOUNTAINS WESTWARD TO THE COAST. MOISTURE WILL INCREASE MONDAY
NIGHT AND LOWER THE RISK OF DRY LIGHTNING.
