How much snow does there need to be for an avalnche to happen?

An avalanche can happen with just a foot of snow (even less) if it's on top of snow that has already iced over.\nMuch more to it than amount.

You actually have seasons. \n\nWinter can be very cold and more snow than usual.

I'm in Salem, Oregon.  It's not snowing right now.  But there is a good chance of it snowing tonight and/or tomorrow.

Cold and snowy (supprisingly enough)

It depends on what you mean by "does it get warm?". See below.\n\nIt can snow even at incredibly cold temperatures as long as there is some source of moisture and some way to lift or cool the air. It is true, however, that most heavy snowfalls occur with relatively warm air temperatures near the ground - typically 15 F or warmer since air can hold more water vapor at warmer temperatures.\n \nWhen is it too warm to snow?  How does snow form if the ground temperature is above freezing?  Snow forms when the atmospheric temperature is at or below freezing (0 C or 32 F) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, of course the snow will reach the ground.\n\nHowever, the snow can still reach the ground when the ground temperature is above freezing if the conditions are just right. In this case, snowflakes will begin to melt as they reach this warmer temperature layer; the melting creates evaporative cooling which cools the air immediately around the snow flake.This cooling retards melting. As a general rule, though, snow will not form if the ground temperature is 5 C (41 F).

A huge factor in snowmaking is not only temperature but humidity. I believe some of the more advanced snowmaking systems can get around this but at my resort I know that freezing temperatures alone are not enough to make snow. Our systems requires that the humidity to be very low or we can't get the water to freeze.

it can never be too cold to snow, as long as you have moisture.  I have had snow where I live at 38 degrees F.  Some people think the temp has to be at 32 or below for snow but it can snow at 35 to 40 degree F, but nothing higher.  As long as you have very cold air in the upper atmosphere, and the snow is heavy enough, then the snow does not have time to turn to rain, so you get snow.

About 6 inches of natural snow base.

It seems to be snow fall.

Really doesn't matter too much.  You want enough that rain water rolls off easily.  Depending upon your area, you might also consider snow load.  Otherwise, do your own thing.

Right now?  It's about 40 degrees Fahrenheit, but it's also night time.  On average, in December, it doesn't get TOO cold yet, it usually stays between 30 degrees (Fahrenheit) and 50 degrees.  It will start snowing and getting really cold in January and February.

I think it would be about 1/3 of theearth gets snow.

Powder is great, and it´s bad when there´s ice! But it´s also good, when the snow is almost melting. But then yah should not fall...

Sure, plenty of snow already - parking lots are full on Mt Hood. The mountains look great from the city already.  Yup, it'll snow some more, even in low elevations... could begin in PDX overnight. basically whenever it looks like it could get below 35 degrees farenheit, there's the possibility of lower actual temps.  Probably won't stick long, tho - unless a ton falls - and it gets clear to keep things frosty.  (AM commuters will need to use extreme caution for hidden black ice and slick spots)

It could snow, or it could be beautiful, I'm afriad you will  need to be prepared for both, as well as the obvious rain!  Smart trousers would normally be fine, it would depend on the person hosting it.  Take scarf, gloves and an umbrella if you will be outside for any of the time.  I would probably prepare 2 outfits and decide on the day, or choose an outfit you can dress up for warmth e.g a dress which you can then wear with a top underneath, boots and tights instead of heals and a pretty jumper and smart coat.  My birthday is late march and last year I was sitting outside the pub in the afternoon, howe3ver a few weeks before it had snowed!.  Have a great time!
