Title: Much Needed Rain Coming to California

As we have written in the past couple of weeks, the Pacific Northwest and parts of the Northern Rockies have had a great start to their water year beginning Oct. 1. Not only will the Pacific Northwest have more chances for rain and mountain snows over the coming weeks, but parched California will have an increasing chance for rain and Sierra snows as well.

A very active jet stream pattern, enhanced by a lot of tropical storm and Typhoon activity in the Pacific Basin will result in parade of stormy weather across the far western states later this week and into November. 

The Northern Sierra drainage is off to one if its best starts in regards to precipitation dating back to the wet season of 1982/1983.

The graphic below shows precipitation relative to normal across the far west and Rockies.  The green and blue areas represent above normal areas of precipitation since Sep. 23. Brown areas represent below normal amounts of precipitation for the past 30 days. By far the wettest areas are in the Pacific Northwest and portions of the Northern Rockies. We expect this trend to continue.

The long range modeling is suggesting that November into early December is likely going to be wet for the far west which is great news for California as well as early season snowpack buildup in the Sierras, Cascades and some areas of the Northern Rockies. The graphic below shows expected precipitation amounts over the next 45 days (through Dec. 5). The red, orange, purple and gray areas highlight the heaviest precipitation.

When it comes to snowfall, many areas of the USA will likely see snow by Thanksgiving. The following image reflects expected snowfall through Dec. 5.  After a pretty warm fall season to date, November into early December will bring some winter weather to most of the nation and some impressive snows in the far western mountains and portions of the Central and Northern Rockies.
