The Euro Control looks good though.

Looks like the multiple storm chances in succession to one another are from various runs bring different amounts of energy, with some leaving it trailing, others bringing the whole package, etc. I'd assume these ensemble means & Winter weather maps are going to be confusing as all Hell over the coming days.

EPS Mean was more positive tilt with the wave this run...resulting in a more suppressed look

I hate to see that 850mb 0c line already retreating North in South Carolina so early on in the runs. Guess we know where this is going for the Central Midlands.

Really like where this one sits 6 days out.

Have to wonder if this is one storm next weekend the models don't have a handle yet though

So when do we expect the pieces of energy to get onshore and sampled better? Until.then trust nothing and just watch the trends at H5

looks like we’re already beginning the event at hour 126yet again, this setup looks to feature a very deep cold air damming setup with a 1039 HP to our north, in fact the mean high for areas north of I-20 is already in the 20s On Friday

This really is the best part of this threat and that's by tonight it will be inside 120 already.

The members that have snow to our N on the EPS still have well below temps, signaling mixed precipitation, we’re getting into that range where it’s almost safe to say this might be legit

Does the EPS pick up on the late weekend system the euro and gfs op have ?

Geez… it’s like mother nature wants to make up for all these weak CADs we’ve seen the last few years, with super CADs

Yeah, this was the 00z EPS

Normally I’d be nervous about a trend like that, but temps/HP placement and everything looked absolutely great, just H5 was more supportive a flatter system, definitely still like the 06z EPS

The mean is further south with the precip though so that's a good sign

It's slightly warmer at the 850s because the n/s wave is a little weaker, but it's rather trivial.

The 0c is like is but the runs are getting colder for us in midlands. Maybe this will be the real ice storm?

Control run is just getting started too....usual caveats apply with a day 5-6 model run
