Rain & Snow for California
An active weather pattern will be developing in the eastern Pacific this week and next and the result will be a good chance for first significant rains in a long time to reach California and other parts of the west this week. The rain will go a long way to help with the fire danger in California but will also cause some headaches with heavy rain causing mudslides and other issues. However, the rain is needed and the rain this time of year is expected.
Below is the most recent drought monitor which shows many areas of the in drought or very dry conditions. Over the next few weeks, some progress will be made in these areas with rain and mountain snow on the way.
In addition to the rain, the first heavy, snowpack building snows of the season will develop in the Sierras and the Cascades. The mountains of Washington, Oregon, Idaho, Montana, Utah, Wyoming and Colorado will also have good chances for significant mountain snows in the next few weeks. Early season snowpack conditions will be off to a good start.
The graphic below shows areas of predicted precipitation, relative to normal over the next two weeks. Notice the green and blue areas (above normal) in California and other western states. These areas of above average precipitation match up well with the major mountain ranges.
