Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

We continue to monitor a very complex system that will bring a mix of precipitation types to the region, not to mention strong winds.
We're looking at some very high ranges in snowfall for this system, there are a lot of moving pieces. It should also be noted that while these are total ranges, there may be a period during the day Tuesday in which some of the morning snowfall melts, or we get rain, before changing back over to snowfall Tuesday night/Wednesday morning.
Hopefully this will give you a good idea of what types of precipitation to expect during certain periods with this storm system. Though again, there are a lot of moving parts and a small change in one could have a significant impact on the types of precipitation and accumulations.
Winds will be an issue with this system with gusts of 30 to 40 mph. This will result in low visibility at times. If we do see ice it also means the potential for power outages
