Rain wanted!!!
Hi,
I'm dying for it to rain here in the SF Bay Area. I live on the Peninsula in East Palo Alto. I just want rain, I miss it so much and everything is getting so dry. This is my first time at this website. Do you all find that the weather predictions here are accurate? Like its says it will rain in No. CA in early to mid-November. Do you think my wish will come true???
Thanks,
Susan
