My morning first-takeaway is higher confidence in freezing rain for Chattanooga. I'm still working through digesting what that will exactly mean.
Not a great update.

A major winter storm and potential ice storm will move through the Eastern U.S. this weekend. Impacts are expected in north Georgia and now is the time to prepare! The forecast isn't as certain for central Georgia, but this is still a situation you should monitor closely. #gawx #Georgia #ice

This is the chance of "Moderate" impacts this weekend due to the winter weather system... Meaning travel will certainly be impacted along with utilities. #SpectrumNews1 #ncwx

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

This should protect confidence in my winter weather forecast, but showing that I'm hedging on icy conditions.

This is one of my favorite plots to convey relative forecast uncertainty for heavy snow — think of it as “1-5 inches is a more significant spread than 8-12 inches, even if both have a 4 inch spread”.
Relative confidence is highest from OK into VA/MD & is low near the north/south gradients.

One of the higher impact winter storms in several years looks poised to impact the southern half of the country this weekend with serious travel and power issues, along with extreme cold farther north. More about what we know - and what uncertainties still remain and why: tinyurl.com/26ysrvhv
High impact winter storm likely to impact parts of the southern half of the country by this weekend, with extreme cold for northern tier
Still lots of details to resolve, but serious impacts look increasingly unavoidable

Models are in decent agreement this AM on a winter storm impacting a large part of the South/SE this weekend. For us, *for now* there's a 65% chance of 3+ inches of snow and a 30-50% chance of 5+ inches of snow. Could be some freezing rain mixed in, but confidence is low on that. More in the blog.

There are different types of winter weather:
There's fun - and then there's dangerous.
This weekend's event is looking dangerous in NC.
Timing: Saturday *and* Sunday
Impacts: Dangerous travel and power outages
Snow amounts and ice amounts could be very high, and stick around for days.

This will be a crippling ice storm for millions of residents in the Deep South and Southeast.
While the placement of the axis of heaviest ice remains uncertain, it's looking like a high-end event that will essentially shut down commerce and travel for days.
