Snow is creeping further and further west
Looks similar to the 12z run, although the snow is a bit more widespread. The coastal low precip also ticked a bit west. It gets some 0.5” totals across the sounds now onto the mainland.
Looks quite exciting for the CLT area, IMO. Not as enthused over here in the Triangle, but we’ll see…

I think we’re going to start seeing precip flourish more the closer we get as the dynamics of the ULL take over. The trough is actually in a really good spot for the upstate and Piedmont to get a decent clip of snow for 4-6 hours and could really drop a solid widespread 1-4”
Right now I see a bombing mid latitude cyclone off the east coast, specifics for the southern Mid Atlantic coastal plain are TBD.
Upstate usually in a favorable spot for Lee side convection. Seen it a time or two. Cant rule it out entirely but Charlotte and central NC seem to be the early model favorites. Worth watching at least.

I’m flying to Boston
certainly feels like there's a little more to be written here. can't wait to see the 3km take a crack at all of this

Here’s what the K index is
The K-Index or George's Index is a measure of thunderstorm potential in meteorology. According to the National Weather Service, the index harnesses measurements such as "vertical temperature lapse rate, moisture content of the lower atmosphere, and the vertical extent of the moist layer."[1] It was developed by the American meteorologist Joseph J. George, and published in the 1960 book Weather Forecasting for Aeronautics.[2]

Well at least RDU still has the SREF NMB control.

Exactly why the SREF is awful. The plumes suck too

Is the western part of the upstate such as Anderson Pickens and Greenville are not going to see any thing for this storm
