It's really coming down, I think it's going to settle.
When we say that snow is settling, we mean that the snow is staying on the ground and not melting. It is a common phrase in the UK where it doesn't snow often - "it's not going to settle" "it's not settling, again".
We say 'it's really coming down' to describe when it is snowing a lot, blizzard like. You can use this phrase for rain too.

I think the snow will have settled by tomorrow morning
I think we will have a 'White Christmas' scene tomorrow when we wake up!
Sometimes the snow falls but the ground temperature is too warm for the snow to remain as sno - it melts almost immediately. However, when the ground temperature is sufficiently cold: 0 Celsius or less, then the snow will 'stick' or 'settle'. If you talk about a 'White Christmas' it is probably in reference to a famouse Christmas song sung by, among others, Bing Crosby. In the UK, a White Christmas means that snow falls and settles on the ground for Christmas Day itself, and it is a well-used phrtase that this time of year.
It looks like the snow will settle by tomorrow morning
By tomorrow morning the ground will be covered at this rate
There will be alot of snow on the ground tomorrow morning if it carries on like this
When the snow is really heavy or snowing alot it tends to all build up or 'settle' whereas if it only snows a little bit it melts and doesn't lay or settle
at this rate means if it keeps going or doing what it is now or 'carries on like this'
雪は激しく降ると地面に 'settle'（積もる）しますが、少ししか降らないとすぐに溶けて積もることはありません。
'at this rate' は「このまま行くと／この調子だと」の意味です。

After this blizzard settles down, we'll probably have several inches of snow on the ground.
"I't been snowing like crazy for awhile now, we're going to have a lot of snow in the morning." Crazy means out of the norm, and here it expresses how unusual the snowfall is.
"After this blizzard settles down, we'll probably have several inches of snow on the ground." Settles down means to slow or stop, and most people refer to the amount of snow on the ground in inches.
"It's been snowing like crazy for a while now, we're going to have a lot of snow in the morning."（しばらく勢いよく雪が降っているから、明日の朝にはたくさん積もっているだろう）
- "crazy" は「普通でないほどに」という意味です。ここでは、雪の激しさを表しています。
"After this blizzard settles down, we'll probably have several inches of snow on the ground."（吹雪が収まったら、たぶん数インチは積もっているだろう）
- "settles down" は「弱まる／やむ」という意味です。たいていの人は地面に積もった雪の量を "inches"（インチ）で表します。
