A: It looks as if the fog is here to stay for a while, however we do have interesting “doings” beginning Wednesday!

The area of low pressure which is enhancing our marine layer is roughly 300 miles west of San Francisco. This morning the marine layer was 2,000 feet deep, resulting in localized drizzle!

Here’s where it gets interesting – computer models suggest the low pressure system will push onshore by Wednesday, tap into subtropical moisture, and produce a chance of showers and thunderstorms.

While the Bay Area needs the rain, the main concern and worst case scenario will be no rain and for dry lightning. The lack of precipitation with this system is due to the fact that the moisture is in the mid and upper levels. I will continue to monitor the changing weather pattern and keep an eye out for A Fire weather Watch if the confidence in thunderstorm development increases for us here in the Bay Area.

By the way, the Greater Lake Tahoe area is under a Flash Flood Watch Monday until 9pm due to expected slow moving afternoon thunderstorms producing brief heavy rain.

I would love to hear from you! Please send weather questions, observations and photos to me, and I look forward to hearing from you!
