High pressure has been in solid control of the local weather for about a week but low pressure returns next week and it'll bring dramatically cooler highs and rain will be likely begin across San Luis Obispo and Santa Barbara counties on Tuesday morning. A threat of showers will continue across much of the region on Tuesday night with a chance of showers continuing into Wednesday mainly in the mountains. While it is still early preliminary estimates indicate that most areas will receive between one third and one inch of rain.
Light snowfall accumulations in the Cuyama Valley with better accumulations in the surrounding foothills as snow levels start at about 4000ft but drop to 2000ft by late Tuesday PM.
Southwest winds gusting up to 45 mph in the mountains could also generate reduced visibilities due to blowing snow.
Due to the low snow levels and potential for icy roadways travel along places like the I-5 Grapevine could be impacted.
There will be a slight chance of thunderstorms across the region. Storms will be capable of producing brief heavy downpours small hail and gusty winds.
This weather system will be dangerous for unprepared hikers and campers.
But in the shorter term the warm weather lasts through Saturday with plenty of 70s once again. Sunday temps will fall 5-10 degrees into the 60s for highs, but it'll still be dry. Monday is cool but the storm system will not have arrived by then.
We need the rain, most of the region is only 50%-77% on rainfall for the season.
