0.9 inches of very wet snow here. That was followed by a little sleet and then light rain, plus the trees dripped all over the place. It was like shoveling water. Nearly all our snowfall this winter has been very dense (sleetstorm) or wet and heavy. Most winters drop mostly cold, dry snow.

Last hour I experienced heavy snow with four rumbles of thunder. The snow has lightened up, so we won't accumulate much.

Jim Cantore just tweeted that he is moving from Omaha to Sioux City to cover the storm.

So the Euro caves to the nw GFS, realizes it just can't hold back the warm surge. I'd say it's just about towel-throwin' time for southeast Iowa. I'm happy for the Nebraska folks, though.... should be a good one.

This..... Compare the 12z and 00z nam. The 12z has a big closed H5 low, while on the 00z run it's totally gone. Hence, the weak surface low and eastward slide. It's real tough to buy what this run is selling.

Does weatherbell have the parallel gfs maps?

I wonder why the models are so different with the earlier lead wave. There is a 15 mb difference between the 12z CMC and UK.

This was a strange Euro run. It takes the low nearly due north and then even back west a bit well into Iowa. It's like the upper low captures the surface low and yanks it back. This would be the worst case for southeast Iowa.

Sneaky decent system we got today. I was expecting no more than a half inch of snow, but I ended up with 2.3 inches. One little pocket that moved over CR dropped the best snow of the season. Of course, this happened after dark again so I still haven't really seen snow during daylight this season.

0.4" here. It's only the sixth time it has snowed this winter.

Given the official hourly precip totals from Omaha and Lamoni, it appears the snow ratios are only in the 10-12 to 1 range... so the cold temp isn't help much. At one point later yesterday it was looking like we may not get anything at all, but the HRRR is trending toward an inch or so this evening.

Every run of every model is south since late yesterday. Now, the 18z nam has removed the snow completely for eastern Iowa north of I-80. Onward to better systems, hopefully. Still should be a decent modest snow event for se NE to St. Louis.

I'd rather go back to the warm, rainy pattern than what we have now. We have one inch of glacier left on the ground, with some grass showing, while we get arctic cold and any precip systems dive to the sw. We may head into February with no daytime snowfall. Things can certainly change, but as of now this winter is a D or F.

This system is really drying up for northeast Iowa. Cedar Rapids is down to maybe an 1 inch on the models. It's just not a good pattern for us.

No, it's not looking good for Iowa again. The cold air will be lifting out before the system arrives, which seems to be a trend this winter. By the time the system revs up and pulls in cold air and moisture, it'll likely be well to our east.

One issue I'm seeing is this system starts out with very limited moisture. It never does have a good feed off the gulf, it just gradually brings in more moisture and matures as it heads into the lakes/OHvalley. It would have to rev up earlier to drop much snow on Iowa.

12z UK revving it up pretty good, albeit way too far east for Iowa to get anything. http://img.meteocentre.com/models/ukmet_amer_12/GZ_D5_PN_096_0000.gif

I picked up a few tenths of an inch of snow yesteday morning. That was supposed to be it, but then another weak disturbance dropped 3/4 inch of snow late last evening to boost my daily total to 1.1 inches. My December snowfall total is 5.4 inches and my precip total is 4.43". My season snowfall total to date is 11.6 inches. Waterloo has already had two 10+ inch storms. My 2015 precip total is 47.13, way above average.

I got some decent snow for a couple hours first thing this morning and a bit more at the end, but the nine hours in between was all sleet. I ended up with about 4 inches. The gauge catch was 1.26", although the real precip total is likely higher because of strong wind. The models generally had me right on the steep cliff with much more accumulation just west and north and not much to the southeast, and that is exactly how it panned out. Our temp never rose above 28, so the stuff isn't wet, but it's very dense and heavy and there's a crusty layer next to the pavement. It was a real beotch to clean. Our first storm back in November was heavy slop, so this winter isn't making it easy.

The warm layer has finally won out over here. I picked up probably 1.5 inches of snow, but now it's light sleet and should stay that way for a while.

Except far northeast Iowa will probably remain all snow. I'm skeptical of 18 inches, but there should be some big totals up that way.

After perhaps an inch of snow, the sleet line has moved in. Areas up by Waterloo should stay snow and get dumped on, but I'm on the wrong side of the fence.

It's still snow here, but radar shows sleet moving in quickly. Waterloo and points north and west are in a sweet spot for 8-12 inches of snow, but sleet should hold us down quite a bit.

The new euro has the low moving up to my east, but there is still an issue with mid level above-freezing air getting pulled back into my area. That's why the wxbell snow map has the heavier snow totals in western and northern Iowa.
