This hazardous weather outlook is for the San Francisco Bay Area
and Monterey Bay Area.

.DAY ONE...Today and Tonight

Mild weather conditions will continue on Saturday with
temperatures around 5 to 10 degrees above seasonal averages.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

A strong cold front is forecast to sweep across the region on
Sunday morning. This cold front will potentially result in the
following weather hazards:

* Locally strong and gusty west to northwest winds from Sunday
  afternoon through Monday. The strongest winds are expected near
  the coast where wind gusts up to 45 mph are possible. A wind
  advisory may be needed for coastal areas from Sunday afternoon
  through Monday.

* Most forecast models indicate the potential for post frontal
  showers across portions of the region from Sunday night into
  Monday, mainly along coastal areas and across the Central Coast.
  In addition, snow levels are forecast to drop as low as 1,500
  feet on Sunday night and as low as 1,000 feet on Monday. A
  dusting to light snow accumulation is possible in the North Bay
  Mountains, East Bay Hills as well as the Diablo and Gabilan
  Ranges. The greatest potential for snow accumulation will be in
  the Santa Cruz Mountains with 1 to 3 inches and in the Santa
  Lucia Mountains of northwest Monterey County where 2 to 6 inches
  of snowfall will be possible.

* In wake of the frontal passage, one of the coldest air masses in
  recent years will settle in over the region. As winds subside
  Monday night into Tuesday morning, overnight temperatures will
  likely fall below freezing across most inland areas and
  potentially even in some coastal locations. Temperatures Tuesday
  night into Wednesday morning may be even colder. Freeze Warnings
  and/or Frost Advisories will likely be issued for this event
  from late Monday night through Wednesday morning. Overnight
  temperatures are expected to moderate by Wednesday night.
