If you'd like to brew tomorrow, you can visit your LHBS and purchase a comparable dry yeast(us-05). If you plan to wait, you can either make a starter for the yeast in your possession or purchase a different yeast. I wouldn't go through the time, effort, and trouble of brewing a batch of beer for a "maybe my yeast will be viable to ferment my batch with good results".
US-05 would be the cali ale dry replacement.
