The weather pattern over the American River Basin is colder at the outset of the project compared to last year. In fact, the storm that impacted our domain over this past weekend and into today has left about 6 inches of snow at Blue Canyon coming from about 1 inch of liquid. Cold core showers may continue through the day and into tonight, but will likely diminish on Tuesday. The rest of the week looks dry, with valley fog being the biggest forecast issue. Therefore, no Intensive Operating Periods (IOPs) are anticipated for the next several days. Klaus Weikmann says that several tropical diagnostics indicate a possible pattern change in 2-3 weeks. This change would involve a strenghening of the subtropical jet, which would presumably aid in the development of atmospheric rivers capable of tapping tropical and subtropical moisture.
Web/Instrument Status Issues
Web page: The project web page is close to being finalized. We are trying to fix a few bugs associated with the Project Information blogs that we used last year. It is anticipated that these problems will be fixed by close of business on Tuesday.
Instruments: More profilers and surface instrumentation are being deployed in northern California this week by PSD staff. The balloon sounding site at Sloughhouse will be ready to go on 2 December (this Saturday). The SMART-R will arrive in the American River Basin by Friday 1 December and will be ready for action on Saturday 2 December,if not on Friday 1 December.
