This looks a little different than their current map... NWS tempering down their own forecast?

This is through Wednesday morning. There is suppose to be a second weaker(1-3")storm on the heels(Tuesday pm) of the big one. So maybe these are 3 day totals. It seems weatherstreet and some of skip talbot's models are showing this. Some are worse.

Are we all gonna die? ****, I don’t have bread or milk, how will I make it?

All seriousness though, how flimsy is that northern cutoff at the moment?

It seems as if the north end of the storm has gone from Interstate 80 to Hwy 30 and now Hwy 20. I suppose we will have to see what the afternoon runs look like

I'm aware Earl is known for some crazy predictions when the storm is still days away, but is it typically more accurate with its predictions this close to the actual event?

I think at this point it doesn’t really matter. 10+ Inches of snow in from one storm is an obscene amount in this state no matter how much ends up falling.

Not typically. What's getting posted here as "Earl" is just whatever the highest model is at that moment. Sometimes NAM, sometimes GFS, sometimes whatever.

Which ever model shows the best Armageddon.

Despite the fact that the raw models , or "Earl", like to throw out 14 and 16 inchers a couple times a week...it only happens once a decade or two.

It will happen again eventually. This one maybe has a better shot than most of recent memory.

Our latest is here...but the way things are trending maybe 8-12 by this evenings update.

I think 6 to 8 is almost a low end lock. Question right now is just how high top end risk is. Will the 12" streak come to an end?

If this thing shifts north at all this could be really wild. Is it trending north at all?

I will put on my Earl cap for a second and say just about every model right now is putting out 10 to 15 from 80 to Missouri.

So this may be as close to the real deal as we've been in a while.

Can't remember the last time we've had a textbook storm like this, four corners low, tracks over St Louis. Thought they'd gone extinct.

This is the traditional set up to hammer Central/Southern Iowa though, if you're rooting for double digits.

You are correct. When I was young the "panhandle" lows like the "oldtimers" told of that swept up around the St. Louis area into the Great Lakes were common at least once a month during the winter season. If you look back a majority of the headline storms came from that direction. Maybe patterns like this cycle every 30-40 years and we are getting back to it.
