SATURDAY April 28, 2012

First, there was no forecast yesterday due to a service outage with the Internet in this area.

High pressure continues to build over California, bringing dry conditions and temps just about normal thru the weekend. As next week progresses, a large storm system will impact the PACNW (say about Wednesday) but it will stay far enough north to only bring gusty winds and a drop in temps to our area. Thereafter, continued dry and mild thru Friday.
