Super Tuesday has no Super consensus.

The noon model runs yesterday looked promising in that we had a general idea of what the storm was going develop and general range of 2-6 inches. It wasn't perfect, but a general idea.

Then the Midnight model runs took place.

NAM and Canadian split the storm-- one piece to our north and one piece to our south.

Euro, which was the driest model at 1-2 inches in our area held serve, but it's parrallel model which takes over in ONE week looks like the NAM.

The GFS has decent liquid getting into our area but the storm is faster and most falls as rain.

There are off hour runs of GFS and NAM.

GFS is faster, wetter and snowless because of warmer temps (Not far off from the midnight run)

There is also a para GFS, which 2 runs yesterday showed 6-10 inches across all of our region.

2 options.

GFS- while warm doesn had the system bringing us precipitation. This is faster than the models and still could bring a 1-3 inch snow fall.

 NAM like solution where the northern energy is separate from the southern and snow falls to our north and rain falls to our south and we are basically dry...(Maps VIA Wxbell)

If the models had held server last night, I would have felt pretty good that we see a 2-4 inch event around here. The fact that even the Euro, which verifies best at 500 MB is split between it's current version and upgrade is even more confounding.

The official Virginiawx.com position is:


I'm going to punt until the next model cycle. Obviously, when a decent storm is on the way at 72 hours out we usually have a pretty good handle on it, so this doesn't bode well. Having said that, I think we could still squeeze 2-3 inches out of it if everything goes well.
