Signs of a weakening #LaNina with warming of sea-surface temperatures in the eastern equatorial Pacific, easing of trade winds & both the 30 & 90-day Southern Oscillation Index averages being near the La Nina threshold. ENSO likely returns to neutral soon.

Stick with me on this next wave! It's still way too early to say for sure what the weekend will look like around East Tennessee, but models are indicating another deep trough to form a surface low somewhere in the southeast. You're likely already seeing images all over social

Dangerously cold temperatures continue across the eastern half of the country. In some places this could be the longest duration of cold in several decades.

EURO FOLDS BOYS. We’ll see where we go from here!

Yes. Recon dropsonde data will be in tonight's 0z model runs. These could conceivably be used as "first benchmark" of which to start looking at guidance a bit deeper tomorrow 12z on. Thereafter maybe seeking trends on subsequent runs becomes a viable practice.

WPC DISCUSSION: ...Southern Appalachians & Mid-Atlantic... Days 3-3.5... ...Confidence In Impactful Snowfall Increasing For the Southern Appalachians and Southern Mid-Atlantic... To say there remains a large amount of model spread in the potential winter storm beyond Day 3

Looks like the 18z GFS/CMC runs got 13-14 dropsondes of 50 total to be dropped. EVMWF gets these as well. 0z modeling should have just about all of em especially Euro. nco.ncep.noaa.gov/status/data/re…

Wait what 💀

Going live to discuss weekend BLIZZARD potential! 🔴LIVE - BLIZZARD Potential Growing This Weekend youtube.com/live/fQw_NCKlj…

Tight western grouping in the 18z EPS. The ensemble members far east are clear outliers. These OTS outliers are likely progressive/squashed or far east ULL solutions. Some of these lows are sub-990mb but have little gain in latitude, doesn’t match overall pattern.

I AM BEGGING

The way this storm will just heal all of us if it can actually happen

1:00 AM: Here come the snow showers. Might be some surprise light accumulation with these for somebody.

Orographic lift on Bays Mountain gonna shock some people again in the morning?…oh boy ❄️😆

December 25th-26th, 2010 continues to look like a great analog for this system. I think we’re in good shape.

Hope you like Winter!
