(KPIX) — An unseasonably cold spring snowstorm will cause temperatures to plunge and drop up to 6 inches of snow clear down to 3,500-4,000 feet on Mount Hamilton, the Santa Lucia Mountains, the Los Padres Mountains, and Mount St. Helena. Even Contra Costa County could get snow at the peak of Mount Diablo, at 3800 feet.

Parts of the Bay Area will see hail, thunder and lightning as the storm front moves through between 6 p.m. and 6 a.m. Tuesday.

The storm will be stronger than the Sunday rain that pushed so many Easter egg hunts indoors before afternoon clearing.

Wind gusts in the mountains could top 40 miles per hour Monday and Tuesday.

KPIX 5 Meteorologist Roberta Gonzales writes it will be an interesting week in weather.
