... Changes coming to the Southern California weather pattern over the Holiday weekend...
A developing weather system over the western United States will intensify and push southward over the weekend. This will bring a variety of weather to Southern California.
In advance of a strong cold front associated with this system... winds will increase out of the west and southwest today and tonight. The strongest winds will be in the mountain and desert areas through Saturday morning. A Wind Advisory is in effect through late tonight for the mountains and deserts. Winds in these areas will be sustained 25 to 35 mph with gusts as high as 50 mph in some locations. A red flag warning is also in effect for the High Desert areas intil 8 PM this evening. The winds will diminish after the front passes Saturday morning.
As the storm system moves east on Saturday and Sunday... cold air will spill into the Great Basin area of Nevada and begin to move into southwest California. Saturday will be the coolest day since last winter. The cold air will also set the stage for the first significant offshore wind... .or Santa Ana... event of the season. The strongest winds will be from late Sunday night through Monday morning. The winds will continue... but weaken Monday night and Tuesday. Humdities will also be dropping rapidly beginning Sunday afternoon and will stay low until Wednesday. Temperatures will be above normal in the 80s west of the mountains... but not the low humidities... combined with strong winds and very dry vegetation... will produce hazardous fire conditions. It is expected a Fire Weather Watch and a red flag warning will be issued for late Sunday through Tuesday.
With the Santa Ana event winds are expected to be in the 20 to 40 mph range... and gusts in favored passes and canyons may top 60 mph.
Please take a moment to review you fire safety plans... and take extra care to prevent the start of wildfires. Smoking materials should be handled with caution.
