Storm timeline: Quick moving storm Sunday, stronger and colder system arrives Monday

SAN FRANCISCO (KGO) -- Our Level 1 system is on track to spread rain from north to south this morning. Amounts will range from a tenth of an inch to over a third of an inch. This is a relatively quick mover with afternoon sun for the North Bay and San Francisco.

Monday's system is a level 1 on our exclusive Storm Impact Scale as well, but it will be stronger, with heavier downpours, gusty winds and colder air quickly following the passage of the cold front.

Thunderstorms could pop up later in the day.
