I see weather.com has us up to a 70% chance of snow. What do the weather gurus say for amounts?
I read 3-6" on Sunday night for eastern Iowa this morning.

Is it that time of year where we get to post weather model maps?
Earl's model says 3"-4" for Des Moines:

This is the only time of year that I know anyone named Earl.
God I hate Earls stuff...there is a lot more to take into account than what that shows.
You take that back.
If I learned one useful thing the last year, it's that you can't trust anybody named Earl.
Not a huge winter storm by any means. This will be a persistent light snow. But the key with this round is the temperatures we will be at. With surface temps in the teen and a large snow growth zone with this one, this will be light, airy, fluff. And that type of snow accumulates quite well.
Expect a snow to liquid ratio around 18 to 20:1. Meaning, if you melted the snow down you wouldn't get much liquid as those wet, soggy, back breaking snows we are accustomed to (closer to a 10 to 12:1).
I'm putting the range at 3-5" in my area (SE MN and N IA). Maybe just a touch more across central Iowa.
Below is raw model data assuming a 20:1 snow to liquid ratio.
Also have a bit of a dry surface layer at first to overcome (and a snow eater east wind at first). Going with essentially a 3.5" uniform blanket for now.
Seems like 3" is a fairly safe bet. Somewhere will likely end up in the 4.5-5" range, but I'm not going to attempt to pin that down yet.
Weather guys trying to politely argue yet engage in brinksmanship...without actually looking like they are doing it...that's what the weather threads are useful for.
Why don't you guys just come out and say "My model is returning results of your head being up your arse."
Is it just me or does it seem like 3" of snow never made headlines not too many years back? It was like, it is winter. It snows. Nothing to see here folks!
Down here in Tulsa, 3 inches have gotten us a snow day and a half.
Here in Eastern Iowa we bring it a little stronger than 3-5 inches. Just saying.
I like John McLaughlin's snow forecast last night. It is going to snow, we just don't know how much yet. At least he was being honest.
Looks like quarter million Dallas Texas homes lost power due to icing storm. Baylor and Okie teams have a game tomorrow.
