This system will arrive tonight and linger into Thursday morning.
Ahead of this winter storm – strong winds will begin over the mountains and deserts this afternoon before reaching the coast and valleys tonight.
This will be more of a wind than rain event. If we do see any rain, it will either be sprinkles or 0.10″ or less.
There could be a Winter Weather Advisory issued later today. There isn’t one now for our local mountains but there are talks that one could be issued.
