Cold Night, Slight Snow Chances, Major Southwest US Storm

After a chilly day with scattered showers and breezy conditions, a cold night is expected. The map below from NWS Seattle shows expected low temperatures.

Expect low temperatures of 25-30 degrees on Tuesday morning. This could cause some spotty black ice, so be prepared.

Regarding snow: 

You might see flakes. The best chance of flakes falling will be Tuesday night into Wednesday morning. If you do see snow, it will not accumulate much, if at all. 

The map below from NWS Seattle shows snowfall from Monday night to Wednesday morning.

Higher hills, mainly above 500 feet, could see a dusting of snow on the grass from Tuesday night into Wednesday morning. If that occurs, don't expect big impacts. The most likely amounts of snow are 0.1-0.5 inches.

Expect high temperatures in the 40s with lows in the 30s for most of this week. Rain will make a return as well.

While major snow is not happening in the state of Washington, a pair of winter storms are moving through the Southwest United States. 

Below is a photo from my relatives in the Flagstaff, Arizona area that shows heavy snow accumulations of 10-25 inches as of Monday afternoon.

Look at all that snow!!! Additional impacts of heavy rain, strong winds, blizzard conditions, and incredible amounts of snow will be impacting California this week. The graphic below from NWS Sacramento shows the massive snow coming to the Sierra Nevada through the end of the week.

Let's put this into perspective: 80-100 inches of snow is 6-8 FEET of snow! (Makes our fuss over a few flakes disappointing!) Where the precipitation is rain, there will be 1-4 inches of rain over a couple days, and that is a major threat with the massive (500,000+ acre) burn scars in the area. California will surely be in the weather headlines this week.
