An oncoming storm that consists of snow. Snow + Storm = Snorm
Damn, those clouds look like a HUGE snorm is comin on, Mothafucka!

Snorm means snot storm. As in a log of snot that is storming out of your nose uncontrollably and you need to always have tissues at hand.
Last night I went to visit my sister and her cold was giving her a snorm.
