OUR clouds and precipitation are being sent down to those poor folks in drought-plagued California. They desperately need the precipitation. And we need the late fall sun.
Let's take a look at this grand exchange, by starting with the visible satellite image this afternoon.
Pretty much clear in Oregon and Washington, but California is enshrouded. Good to see.
The 7 PM Sunday surface chart shows the situation. High pressure over us and a frontal band bisecting California.
Here is the storm total (last two days) from the San Francisco radar--lots of areas got 1-2 inches!
Californian's are seeing something there are not used to: rainbows. Perhaps a sign from providence that their suffering is ending.
And yes, the weather gods seem to be taking a liking to CA folks. Let's take a look at some upper-level (500 hPa) maps, starting with Tuesday evening. A closed low off CA, with strong flow (lines close together) heading into central and southern CA.
4 AM Friday? A trough offshore and moist southwesterly flow heading into CA. You can bet on precipitaton.
They need a lot more than this, but a good start. This is an weak to moderate El Nino year, and El Nino years (particularly strong ones) bring enhanced rainfall to southern CA. The latest NWS Climate Prediction Center 3-month precipitation forecast is going with that idea.
This event is literally a drop in the proverbial bucket for California, but it is a welcome first step, considering the historic drought hitting that state.
