Your Storm #40 Headquarters!

Update 6

Wow! Storm 40 Delivered! We got quite possibly a half inch, maybe more. But it Came through hard and strong with wind and rain and is now roaring into Utah with snow and ice.

Update 5

Here it is bringing extensive heavy rain and snow to inland Central California.

Update 4

The storm is here. Looks pretty tame.

Update 3

3:30 am. Outside, still night air, heavy and moist, hazy starry sky, and a very slight steady movement of air from the south, creeping deliberately. And a small chorus of nearby nightbirds, chattering loudly, echoing about the walls and fences.


Watches and warnings have been expanded for the valley eastwards into the great western wilderness.

Update 2

Tonight at about 9:30pm, we are under clear skies -- no sign of any storm. But there it is, coming for Northern California, making impressive tracks south. The Cyclone really churning fast! You gotta see the animated sequence. Still a tad disorganized looking. Doesnt have a strong look.

Update 1

On the extreme left of the image, below that front headed for Washington and Oregon. I think that's Storm 40. Weather service now calling it strong and upper air disturbance. Predicting .25 of an inch for the valley, 2 inches for the foots, but probably not since it appears to be a Northern California storm.

This is Storm 39, responsible for yesterday's cloudy afternoon.


Welcome to the Storm 40 Headquarters. –Insert Theme Music Here–
Watch for updates to this blog as Storm 40 develops, then either winds up being a dud, a memorable weather event or a nice topper for this year’s generous glass of precipitation!
Wow! I badly interpreted the visible light satellite photo from yesterday of Storm 39 above. This is a very stormy picture! Check out the “eye” just off Puget Sound! That is the hub of a strong Alaskan low. It is way south of where you’d expect it to be right now. It’s April. It should be retreating north. When this happens, usually it’s because El Niño has pulled the weather map to the south. Warm ocean surface temperatures have a suction effect. This is a strong storm setup. The weather service has already thrown up watches for a fresh, new storm. A cyclogenesis right off the California coast would have great potential. Add in the fact that the sun is stronger now, creating more instability, and things could get interesting!
