After a pleasant weekend, major changes are in store.

A powerful, moisture-driven storm is placed over Northern California as of Sunday evening and will then make its way down California toward San Diego County. It will lose some strength as it passes over land, but will still bring significant rain totals to Southern California.

The timing of this storm will favor Monday in the afternoon and evening hours. Monday morning, there could be some light rain, but starting in the afternoon, that rain really picks up, peaking in the dinnertime hours. By Tuesday morning, it will push east and sunny skies will return.

Rain totals in Northern California are high so far. Some parts of the Bay Area have already seen 4-5 inches in the last day. Totals in San Diego County will be a fraction of that, with tenths expected for coastal and inland areas, but half an inch possible. Mountains could surpass half an inch of rain. Deserts will not see that much, with hundredths or tenths more likely.

Winds will also pick up simultaneously with this storm. Monday, areas west of the mountains will see gusts in the 15-20 MPH range. Mountains and deserts could see gusts up to 40-50 MPH.

Monday will be the coolest day of the week with temperatures dropping below average across the map. Tuesday, gradual warming will begin, with highs quickly jumping back to the 80s for coastal and inland areas by Thursday. Sunshine will persist for the remainder of the week.

Monday's Highs: 
Coast: 65-67°
Inland: 63-68°
Mountains: 51-64°
Deserts: 75-86°
