The 18z Icon match the Euro and did this also. Seems there's no avoiding that track, it stays further south initially and the HP moves offshore when the low's further south and has more time to pull it back west before it gets here.
We need it to trend 300 miles ENE to make a big difference which doesn't happen with disturbances tracking across the gulf coast. That's why I gave up on big snows for 95% of the area this morning.
Almost ready to give up on this. The shortwave isn't going to trend east, and the high isn't going to stick around. Likely a lakes /Midwest snowstorm.
Only hope is if the shortwave cuttsoff over the southwest or something ejects ahead of it.
Nothing off the table, could track easily track over Detroit, or end up a cutoff low over Arizona. There isn't anything really pinning this pattern down.
Got a high in the perfect spot, a 50/50 low and the shortwave is a well defined 540-546 split. This is usually how a KU storm starts, not saying it will happen though.
JFK: 8.1" on .9 precip but Flushing Meadows 7.9" on .53" precip.
Didn't happen they were both along the same band.
The .53" is probably correct for both sites. Gives about 15:1 ratios.
