The forecast is on track right now for two waves of energy to move through the area in the next four days.
The first round will push into the area late tonight bringing with it rain to our northern areas (San Luis Obispo and Santa Barbara) and light showers to the south. This will move through fairly quickly Tuesday morning and we actually will see some clearing in the middle of the day.

The second cold front will move through on Wednesday, starting along the Central Coast well before sunrise and we may see some pre-frontal rain in our viewing area during the morning. The rain will pick up in the middle of the day and into the evening.
We are looking at about six hours of steady rainfall for the area, and we could get up to 1/2 of an inch when all is said and done.
Once the system moves out, the atmosphere will still be unstable, so there will still be a chance for a thunderstorm early Thursday. Things will gradually warm up into the weekend.
At the end of the day the system is moving fast, so it is not really a huge deal. However as it is the first real powerful winter-type storm of our rainy season, it will appear bigger than it actually is to all of us who have been bathing in sunshine for the summer.
I’ll have more updates for you tomorrow.
