Wintry Dec 8-10th Winter Storm

[Yellow Snow]

The storm has Ryan Maue's attention...

I got a question. Where is the cold air coming from? A HP in the NE or a HP in the Plains?

There's a push of colder air in SE Canada that allows the high located in the Northeast to funnel colder than average air (this time of the year) down.

The High in question that sets up, moves in tandem with the low pressure system... timing is key here, of course.

Really both!

From the 12z Euro Ensemble Mean, this is about as good as you can get with a signal for a Wintry event.

Needs to keep coming south I honestly hope this thing doesn’t look good until the day before the event and then rip out my heart by going way north. Already had that with Georgia football

Perfect track for central AL and GA. Just need enough cold air.

Agreed

I will make a call for upstate, 3-8" sn/ip and up to .25" ice. That's a pretty safe bet.

That LP did get a little suppressed from earlier runs.

This is fun but can we skip to NAM time??? Trying to patiently wait....

I'm predicting 12-18" snow for the Greenville area with less than .10" of ice.

The amounts and distribution of precipitation on last available frame of the 12z UKMET certainly looks nice on weathermodels.

Rah NWS has "snow likely" Saturday night, aggressive for them to say the least, especially as far east as mby

There are no safe bets with southeast winter storms ESPECIALLY 6/7 days away

Agree, that is heavily unlike them!! I remember quoting them on multiple occasions when everyone was snow-weenieing and saying well "RAH isn't calling for that", and everyone tried to tell me why (they are conservative).

Man, don't we know that too well.

Mets may be willing to take things a big more seriously after what has happened in recent years, particularly in the Atlanta area.
