Update 7:29 p.m. from KSBY Chief Meteorologist Dave Hovde
If you scroll down you'll see the history of our coverage from earlier today.
The severe storms have ended but not before doing significant damage in the Grover Beach area. At this point it is not clear if the damage was from straight-line winds or a tornado. The National Weather Service will be on the Central Coast Thursday morning to determine how the damage was caused.
Here at the top of the article, I'll cover the upcoming forecast and you can find out more about what happened earlier by scrolling further down.
The storms Wednesday were caused by a surface trough rotating thru a larger upper-level trough still over the Central Coast and California. The line of storms included small hail, strong winds, and thunderstorms. The line also moved very rapidly, at 50-60mph. The brief but strong line was already into Ventura county by 7pm.
Even though the main band is done, there is still upper-level instability in the area and on-and-off showers, and small downpours are possible thru Thursday but the upcoming activity will be more brief and much less powerful. The trend will be for more "off" than "on" activity.
By Friday a ridge builds over The West and temps slowly warm back into the 60s and even mid-60s early next week.
