Super soaker ‘Pineapple Express’ organizing for heavy rain in California this weekend – as much as 20 inches in some areas

This was a post on Watts Up With That, the worlds most read climate blog, providing analysis from Dr. Ryan Maue at the Weatherbell.

Looking at the model output below, I tend to agree, if the pattern holds. It sets up Northern California for the perfect orographic lifting enhancement in the Sierra Nevada mountain range that will not only provide a bounty of liquid precipitation, but a significant boost to the well below normal California snowpack.

The Quantitative Precipitation Forecasts show some parts of Northern California getting as much as 20″, along with many mountain areas getting 5″ or more.

How much will be snow, we will have to wait and see. On the other hand we could have some serious flooding. In winter of 1861-1862 it was series of these events that flooded the valley from end to end like a bath tub 20 feet deep. In Sacramento, they came and went from the second story windows in boats. According to historical climate data, these serial rivers of rain come about every 150 years and we are over due. Stay tuned.
