WY2016 Storm 56

Scroll down for latest – I don’t like inserting updates on top because everything reads as happening in reverse order.

I. Welcome Storm 56!

Coming in from a far NorCal position and sweeping south, Storm 56 is expected to be a minor-to-semi-significant storm for Tuesday, 160308. Associated with it is winds and light rain. The real weather doesn’t start up again until Storm 57’s arrival on Thursday. This was a day off. Great day to ski due to very minor weather hassles.

Lake Tahoe on 160308 at 1200 PST: the new storm clouds are here.

II. Storm 56 Progress

Tuesday, 160308

1100 PST Tuesday… light morning rain from storm 56…Storm-56-160308-radar-1100PST.jpg

1600 PST Tuesday… weather chart shows major cyclone in the Gulf of Alaska, and below a series of developing storms just offshore of Northern California and Oregon. Storm 56 is one of them currently developing and intensifying. GofACyclone-Storm56below.jpg

Wednesday, 160309

1115 PST Wednesday – light to moderate rain with high winds up from the south from Calif Border  to Seattle. Storm56radar160309-1115PST.jpg

1200 PST Wednesday – The jet stream has left its El-Niño influenced positioning in the Western N. Pacific for the first time since November 2015! The mass dissipation is rapidly advancing across the sea. Forecasts of weekend storm intensities have been scaled back. Once this series of storms is through, the next chance at California storms is sometime in April, according to projections. PacificJetStream160309-1200PST.jpg

1630 PST… Wednesday: the storm that is horribly stranded offshore (that’s our storm 56) has a unique feature – two cyclones working together to power the atmospheric river into the Pacific Northwest. Good news, though. Starting Friday, California is going to get some sloppy seconds. Wonder-Twins-Storm.jpg

1647 PST… Wednesday: The storm’s eastward progress is stuck. There’s a huge, delicious atmospheric river rocking and rolling its way into Seattle, kind of also hitting western Oregon, and clipping the far NW corner of California, the only part of California not in any sort of drought stage. It’s no good. Should have hired a rain dancer. They’re calling Storm 56 the “wonder twin powers” storm up there. It has two cyclones. It’s a binary storm system. See the two twists in the clouds west of WA and OR?Storm56-Day3-AtmosphericRiver.jpg

1627 PST… Wednesday: radar shows Portland, Seattle, all those places, which have already broken all sorts of rainfall records in Water Year 2016, is getting all the rain from this screwed up El Niño of 2016 all the way to the end. California got the surfing waves. Cowabunga.Storm56Day3.jpg

1650 PST… Wednesday: Storm 56 is two systems in one. Usually when two cyclones get close together, they merge. I suppose this will happen eventually.  CdJVQ6VUEAAKyEf.jpg

2300 PST… Wednesday: Storm 56 has begun to move east. The Atmospheric river band is now coming ashore in Northern California and traveling over land on its way to the storm core offshore of Washington State.  It is expected to stall again in this position, and cause a significant rain event in the North Bay Area of California.

1430 PST…  The second atmospheric river in the picture belongs to Storm 57. Those two “rivers” are going to get smashed into each other when storm 57 arrives in California because Storm 56 is not moving. Supposed to happen from 4-8 am Friday. That merge will be happening as the fronts, one right behind the other, and rain arrive in the central San Joaquin Valley. Could be a very interesting morning tomorrow.

2200 PST… The red arrows are supposed to show where the center of Storm 57 is moving to by 0400 PST Friday. The yellow arrows are cloud movement. Bigger=faster. AS SOON AS STORM 57 AND STORM 56 TOUCH, STORM 56 IS OVER.Storm57-vs-Storm56.jpg

0300 PST… 160311. Storm 57 is touching Storm 56. Storm 56 is dead. Skip to last section to see the storm totals.

IV. How Storm 56 becomes Storm 57

How Storm 56 comes to an end is tricky. Storm 57 is going to ram the atmospheric river, currently feeding along the stationary cold front of Storm 56, which is running out of steam, which is stalled over the San Francisco Bay. When the Atmospheric River is shoved towards Fresno, supposed to happen around 8am Friday, Storm 57 takes over the atmospheric river and takes it southward to the rest of California.
