Dry December Update

“Rain, rain, rain, rain,
Why’d you cause me so much pain?”
—”The Rains Came,” Sir Douglas Quintet

Southern California got a little spritz of rain over the weekend—nearly a fifth of an inch yesterday in the desert town of Blythe. Here, it’s dry, and the California-Nevada River Forecast Center sees only a small chance that rain will fall over the northern part of the state in the next week (and that will be far north of the Bay Area). Our local National Weather Service forecast office, in Monterey, reads the models the same way: “Dry and mild weather will continue through at least the next 7 days … with little variation in the upper level weather pattern. A series of storm systems will move towards the region over the next week … but pass to the north and east of the area. ” The longer-range outlook from NOAA’s Climate Prediction Center is for drier and warmer than median weather.

Here’s the local NWS table on precipitation so far this year. And below that, today’s theme song

Coming Attractions: Autumn Rain

There it is: our first storm of what we’d like to call our rainy season (the live version of the image is here). The National Weather Service has been advertising this as a “rather weak” system that won’t drop much rain here. Maybe so, but the radar image–which doesn’t always depict what’s out there in the atmosphere–seems to indicate some moderate to heavy precipitation off the coast. We’ll see in the next few hours.
