This line will get to the mountains around noon and slowly work south, getting to the foothills and central highlands between 3 and 5 p.m. From there it will continue to sink south, getting to the coast after dinner. Here's a look at the timeline:

We'll be tracking these storms all afternoon and evening and will pass along any warnings both on TV, online, and through our various social media platforms.
