Winter Storm Update from CWG

Update from Capital Weather Gang (via x / twitter viewer.com)

Major winter storm possible this weekend in the D.C. area 👀

We’re tracking a storm that could bring substantial snow + record cold to the Mid-Atlantic if key pieces come together. Here’s what you need to know right now:

🗓️ Timing • Snow could begin late Saturday or early Sunday • Could last into Monday morning • Long-duration event = possible school + business impacts next week

🌡️ Bitter cold setting the stage • Arctic air arrives Friday • Highs could struggle to reach 20° Saturday • Whatever snow falls would stick around a long time with freezing weather next week

❄️ How much snow? (Big range!) Model averages for D.C. range from 0 to 15+ inches; way too early for exact numbers. • Most model averages: 8–10 inches • Some show double digits • A few keep us much lighter Bottom line: Confidence in accumulating snow is rising, but totals are still highly uncertain.

⚠️ Why this could bust If the southern and northern systems don’t merge well, moisture may not reach us — keeping the storm mostly south. Some models still show this lower-impact outcome.

🚨 Why this could be big If the systems merge efficiently and pull in Gulf moisture, we could see prolonged snow with powdery accumulation that piles up fast — even without huge precipitation totals.

🛒 What you should (and shouldn’t) do now • Too early to cancel flights or major plans • Smart to start thinking about a Plan B • Not a bad time to grab salt + shovels before any rush

📌 Bottom line: This is a high-potential, high-uncertainty setup. We’ll gain much better clarity by Thursday–Friday.
