Winter Storm Update (7:30pm)

The afternoon model package has arrived, and shows a very impressive output! Most spit out a good 7-10″ across the area, with isolated 11-12″ amounts! Everything is right on track with my forecast, so there are no real changes to talk about. The ULL (upper-level low), currently located over central MO, will continue to slide southeast then east as it approaches the tri-state. Most models track it through north-central KY, which is exactly where it needs to go to have a large snow event across the tri-state. The Gulf of Mexico is now open for business as the low is already tapping moisture from it. This added moisture will allow for the snow to become very widespread and heavy. We’re still on track for a start time between midnight-3am, with scattered snow showers possible at any time before that. By sunrise, expect a solid 2-3″ on the ground, with several more inches to come after that!
