Two jet streams, and disturbances within now coming into the West Coast, are going to combine to produce an exceptionally strong #cyclone -- with #blizzard conditions, #severe thunderstorms, heavy #rain & #snowmelt, and strong gusty #wind pic.twitter.com/DTVUSzP2A2

Plains #blizzard, #WinterStormUlmer, may bomb out and smash all-time low-pressure records in parts of the Plains. (Kudos to @DRmetwatch for perspective.) https://t.co/EwDLhC0OiE pic.twitter.com/PGRhrLxHZO

You'll likely hear the words 'Bomb Cyclone" or "Bombogenesis" tied to this next storm.
