An excruciatingly slow moving upper level low pressure system tracked across northern Wyoming and into the northern plains over the past five days. It was also accompanied by an abundance of moisture and some very cold temperatures aloft. This system will continue to wrap moisture around the low and into the region through Saturday.

Snow and rain will finally taper off on Saturday afternoon and evening.
