  snow is possible in the Santa Lucia Mountains in Monterey

* Blustery conditions and low wind chills with locally strong
  northwest winds. Northwest winds will increase from late
  Wednesday night through Thursday afternoon. Strongest winds are

  and evening when gusts up to 40 mph are likely. Wind chills will
  be as low as the 20s to mid 30s by Thursday evening.
