Update on California Storm Plus Its Effects on the Great Plains

Snow has been falling in Southern California today and it will worsen tonight. For the first time ever the National Weather Service's San Diego office had to issue a blizzard warning. It was for the mountains in Riverside County. 

Here are the latest warnings, et cetera. 

Here are the color codes:

• Orange = blizzard warning. 
• Pink = winter storm warning.
• Green = flood watch.
• Gold = high wind warning. 
• Sand = wind advisory.
• Dark blue = winter weather advisory. 
• Dark green (one county south of Las Vegas) = winter storm watch

Sacramento may have snow tonight. If so, it would be the first since 1967. 

This powerful storm will move east, thus the winter storm warnings you see in Nevada, Arizona, Utah and Colorado. The National Weather Service's Storm Prediction Center is forecasting unusually early tornadoes -- accompanied by large hail and damaging thunderstorm winds -- over the areas shown below. The forecast is valid from 6am Sunday to 6am Monday. 

The darker area is where the tornadoes are more likely along with the larger hail. 

More tomorrow.
