First "Sizable" Sierra Snow Storm?

Rain & Snow Forecast Thurs Night through Daylight Hours of Friday

Wet weather coming to Mother Lode from Gulf of Alaska,
Union Democrat, October 16, 2017.

 

This will be the third and strongest of snow events in the Sierra approaching the Winter of 2018. The first two were unexpected little local Lows that laid down some snow. Sweet. This one comes out of Gulf Alaska, as is traditional for the Sierra Nevada. Sweet.

We need rain to break drastic fire conditions up and down the West Coast of the US, from the Pacific Coast to the Sierra Crest. Everything in-between has all been drastically hot & dry.

I have been watching the low dragging this dissolving front towards us, thinking, "that's going to get pushed further North than they expect." Initial forecast was for light rain on Wednesday, but was pushed back to Thurs. and Fri. I would be ready for this weak front's worse, most powerful potential, but not surprised at all if this instability weakens further and passes to our North.

That means this weather could be more dangerous. The failure of snow typically means cold rain, which is harder to defend/insulate against than cold snow. Thus our gear requirements must favor defense from cold, wet rainy conditions, & wet snow.
