Euro Ens Mean - not much change from the 00z run. It has the appearance of being a little colder, but that's just because it's a touch faster to bring the cold air in. Probably some decent hits on the members, but I haven't seen them yet

The Euro turns the corner late with the wave, just in time to hit Eyewall

Maybe at the surface, but upstairs it more of a Dec 2018 look (storm that hit NGA and the mtns) - that is, positive tilt trough dives down and brings the cold, then SW flow commences along the boundary.

Euro at it again

I can see the thread title now - "The Eyewall Snowstorm of Feb 2020"

More of the same ahead. Low anomaly centers in Alaska and Iceland...what a winter (image from twitter @MJVentrice)

Negative anomaly associated with the 500mb trough is over 5 standard deviations below normal

Here is the Integrated Water Vapor Transport chart showing the large values / large arrows

WPC Excessive Rainfall Discussion... ...Southeast... Widespread heavy rainfall is expected today across much of the Southeast with impressive moisture parameters in place. Both PWs (Precipitable Water) and IVT (Integrated Water Vapor Transport) are around maximum values for early February over the entire Southeast (it is quite impressive to see such a large geographic area with around record values). Thus it seems fair to say that from a moisture and moisture transport perspective you will not see a better setup this time of year than what this event will have to work with.

We’re not even getting into punt formation this winter. We’re throwing pick 6’s and getting strip sacked. Maybe we can pull a late fluke after a lot of warmth like Feb ‘89

Best we could do today (about 30 min ago)

Some large flakes mixing in with the rain in these heavier returns on radar

Light rain with a few flakes mixed in...37 degrees. Looks like this will end up somewhere between the morning 3km NAM and HRRR

Don't know about in the mtns, but man, out here the NAM has certainly been as good as any model in winter for several years now with it's overall ideas, even at range.

3km NAM sounding at 1PM for Lincolnton, NC

Go with wet bulb temperatures. You need wet bulb temperatures through the atmosphere to be close to freezing or lower I've seen snow at temperatures as warm as 43, and sleet as warm as 50.

Latest HRRR at 1PM and 2PM today

Latest 3km NAM at 2pm and 3pm today

Widespread snow from Birmingham to Raleigh is quite rare for any month, but the March 1983 storm fits the general narrative

AO has been brutal since Jan 1. AO forecast is high and trending UP

My understanding from years back is that a Meteorologist is someone who has a college degree in Meteorology. Pro Forecaster is someone who is, or has been, employed in the weather forecasting industry, but doesn’t have the Meteorology degree.
