The 00z GFS nudged north as well. The south edge in Iowa may be razor sharp. The Chicago area at least gets a late influx of moisture as the wave reaches them, which spreads the love a bit.
A few of the models overdid the snow here, on the nw edge. I only got 0.6". The trailing energy dropping in from the north now may also produce its snow a bit farther east. I might get another 0.5" tonight.
The 00z Euro has the upper energy digging southward into Iowa pulling some moisture back northwestward through cyclone and into northeast Iowa. Models have been teasing this a bit, but it comes and goes. It wasn't there on the 12z Euro.
I received 1.1". Models never agreed, but I got about the average of all of them. The wet Euro from a couple days ago was very wrong, but so were the bone-dry CAMs.
Models have this upper low dipping across the Mexico border. That's simply too far south for Iowa. We need this to move east across NM and into the TX panhandle.
Unsurprisingly, the 00z Euro did pull back a bit from its 18z run. However, it still has a decent, light event. I'd like to get some insulation on the ground before the cold moves in. I'd take 2".
The 18z Euro suddenly greatly increased the band of snow up through Cedar Rapids. We went from 1" on the 12z to 3+" on the 18z. The 18z H5 maps show a sharper wave over my area, but it wouldn't surprise me if it's just a one-run blip. Other models are much drier.
We started as snow, but quickly flipped to mix for a while. Once we flipped back to snow much of the precip had lifted north. My mix/snow total is 1.1". The liquid total is over a half inch, so this stuff is super wet.
