In what has already been a frigid December, yet another cold plunge is on the way. Here's how cold it will get and whether there is any relief ahead.

Another Alberta clipper system will bring snow from the northern tier into the Midwest and Northeast this weekend. Major cities along the Interstate 95 corridor, like New York City and Philadelphia, could see their first measurable snow of the season. Widespread snow totals of 1-3 inches are expected with totals up to 8 inches possible in some locations. Check out the timing here.

The National Weather Service warned of potentially "catastrophic" impacts from the flooding that's setting new records.

The heaviest rain will shift north into Canada Friday and Saturday, so expect rain to ease across the state of Washington. However, rivers are still running high, so it will take another day or two for water levels to come down. Unfortunately, more rain will move back into the Pacific Northwest on Sunday. The flood threat returns through at least the middle of next week as the rain becomes heavier and more widespread. Watch this video for the latest update.

Repeated storms from September through November have revived a prehistoric lake in one of the driest places on our planet.
