Another storm heading our way, this one should be more impressive than the last, at least in eastern Iowa. 4-8 inch marks, locally higher east of I-35 look to be what the models are pointing at. West of I35 things are a bit more dicey just depends on where the snow sets up.
Winterstorm: 2/7-2/9

Just when I thought it was safe to start enjoying the nice weather, you drop this on me. :wink:
The main thing to watch for with this system will be how quickly and how strong the dry slot comes in from the southwest. If it's strong and fast, less snow. Weaker and slower... more snow.
It'll be more than that, although if your just talking about Sunday that could be right, Sunday the precip will be pretty light before picking up some on Monday.
Here I'll link you the bufkit sounding models estimated precip for Des Moines(these have jumped up in the latest runs).
GFS: http://www.crh.noaa.gov/bufkit/dmx/gfs3_kdsm.dat
Shows 12 inches actually(too high imo)
NAM: http://www.crh.noaa.gov/bufkit/dmx/nam_kdsm.dat
Little more than 6 inches, seems more likely to me.

I live in Cherokee, IA and you were pretty much spot on with ice Friday morning and a few inches of snow.
So as I look at your links, one model looks to predict 6 inches while the other is aiming at 12 inches of snow.
What part of Iowa is this for? None of the stations in Des Moines or Sioux City are calling for more than 2-4 inches by the end of Monday night. I think if we are looking at 6 inches we should be in a winter storm watch and 12 inches should be a winter storm warning.
I know that I'm happy I got my snowblower fixed today if this storm is going to be as significant as your talking! Thanks for any additional clarification.

Winter Storm Watch will be going up for Central Iowa Monday- Tuesday. Here's some quotes from the DSM Weather Discussion:

Holy cow, I looked at Earls 120hr precip map this morning and it didn't show a lot of snow. Now after finding this thread I go look again and boy how it has changed.

Didn't they announce last week that DSM (or Central Iowa or something) just set a new record for continuous snow cover of at least 4". Something like 55 days.
With these new systems, that record will be absolutely CRUSHED by the end of winter.

What I linked was the output for just Des Moines. The general site is right here:
Bufkit Data Available from NWS Des Moines
Just scroll down to where it says:
Cobb Precipitation Type (ver. 5.4) Output (NAM) and Cobb Precipitation Type (ver. 5.4) Output (GFS).
Then just click on the town/city thats closest to you and you have a general idea what 2 of the models that forecasters look at are thinking.
As far as forecasting goes: Anywhere east of I35 looks be solid for 8+ inches of snow now. West of I35 totals will gradually taper off as you head west, by the Missouri River there might only be 3 inches or so. Towards the end of the storm the winds will pick up creating visibility and drifting problems Monday night into Tuesday. This is not a storm thats going to drop a ton of snow at once, more just steady snow over a prolonged period. Just pay attention to what the NWS is saying, they seem to have a good handle on the storm(they placed the Winter storm watch pretty much exactly how I figured).
