0z NBM looks good. Off to a good start for the night. Some folks may not know what exactly the NBM is. It is the National Blend of Models (NBM) and is a nationally consistent and skillful suite of calibrated forecast guidance based on a blend of both NWS and non-NWS numerical weather prediction model data and post-processed model guidance. So the 00z version is actually based on model data from earlier in the day. So the 00z output reflects output from earlier in the day... not the 00z models. |

It’s always nice to see the NBM go up consistently. That’s a good sign

18z Euro only goes out 90 hours, but it is digging the energy further SW compared to the 12z run. Unfortunately 90 hours is the crucial point. But, I do see the Hudson low shifted east flattening the ridge side of the system and just barely opening up the upper low level in North Dakota. This gives the thermal gradient a more zonal orientation. It's certainly not a cave to the GFS but it is a step in the right direction. It is at least trying to start cyclogenesis further south and west on this cycle and hints at the possibility of GYB potential. |

NAM at 84h looks good, much more in the GFS camp

It’s always more exciting when you get with in NAM /SREF range two more models to watch come out

00z Icon has the most amazing temp gradient I’ve ever seen.
Very impressive run for STL.
Actually, a bit too far west for me lol.

Man there are some amazing ingredients to work with, it’s almost like the perfect setup for a massive storm for Stl . Definitely things could change, i but currently we’re in a good spot for a crazy storm

GFS looks a little west through 84
Still digging. Going to be another monster but definitely west.
This sounds crazy but it looks like it’s going tonight be a bit more amped as well.

STL goes from 40 to 12 degrees in 3 hours on that run
Talk about flash freeze

This run seems very weird to me, the center of low pressure hits central Mo and then goes straight east over StL it looks like.

The GFS is not a complete miss by any means
We would still get several inches of backside snow
