Pat's Forecast: Winter Storm Arrives Tonight

SAN DIEGO - Tonight the action begins...rain in the mountains first, then becoming more widespread as Saturday progresses.  The winter storm that formed in the Gulf of Alaska will give San Diego a wet, cold, windy weekend.

Saturday's Temperatures:

  • Coast: 62-67°
  • Inland: 51-56°
  • Mountains: 44-50°
  • Desert: 63-68°

Winds: Westerly winds will be gusty at times through the weekend, especially in the mountains and deserts. A Wind Advisory has been issued for the desert through 3 a.m. Sunday. Winds peak Saturday with west winds 25 to 35 mph and gusts 50 to 60 mph.

Timing:  Moderate scattered showers will pick up overnight into Saturday.  Peak activity will be Sunday with  showers continuing into Monday and a slight chance for Tuesday. There is a slight chance for thunderstorms that may produce heavy rain, damaging winds and small hail.

Snow: This system will be colder than last weekend's, so expect snow in the mountains. Snow levels will start off high at 7000 feet Friday night.  By Saturday night and Sunday, snow levels will drop to 4000-4500 feet so Julian could be looking like winter again. Snow totals from 4,000 to 5,000 feet could be 1 to 4 inches with 4 to 8 inches possible from 5,000 to 6,000 feet, and locally higher amounts.

Winter Storm Warning: Saturday afternoon through Monday afternoon for moderate to heavy snow at times above 5,000 feet. Gusty winds up to 60 mph may cause blowing and drifting snow reducing visibility and making travel hazardous. Avoid travel if possible.  If you must drive, carry chains.
