Hawkeye Posted January 10, 2020 Report Share Posted January 10, 2020 another nice run of the RAP for many reading and still snowing heavily at HR 21- https://www.pivotalweather.com/model.php?m=rap&p=snku_acc&rh=2020011004&fh=21&r=conus&dpdt=&mc= I don't like the way that snow plume is aimed into northeast Iowa. I'm definitely concerned that strong warm air advection may lead to this. It's going to be a pretty picture just north of that snow/sleet line.... will probably be dumping big flakes.

Grizzcoat Posted January 10, 2020 Report Share Posted January 10, 2020 I've noticed that as well. The only real change I expect is a juicing-up of the first wave because the last couple runs have been pretty weak and dry.Maybe the UKie's had a govt shutdown.... ) Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

I'm definitely concerned that strong warm air advection may lead to this.I hear ya. Of course when you are in the heavy snow potential - the sleet isn't far away and warm air. Concerned about that here. But a reason I had some hope being NW of this for most of time was that this would happen and shove things NW. Pick your poison I guess. 2 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Grizzcoat Posted January 10, 2020 Report Share Posted January 10, 2020 Thing that most outside the weather field fail to understand is how incredibly difficult it is to get a snowstorm (or even several inches this year) as so many atmospheric variables have to be just PERFECT. Too cold- and no moisture. Too warm and it's rain. Too much warm air aloft with cold ground temps = freezing rain etc...The ways NOT to get a snow event are nearly endless and only several ways exist to actually get one and why they are so special (outside the fact I enjoy winter) meteorologically. 4 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Hawkeye Posted January 10, 2020 Report Share Posted January 10, 2020 I was a bit annoyed this morning when models were dancing around, but I'm content with whatever happens. If the waves split me and I get nothing, oh well. We'll get a good storm again sometime. If there is little/no snow, I won't have to shovel much and I'll be able to continue to walk outside on dry ground. That said, it'll be tough to take if I get nothing while 10 miles nw gets 4-6" of snow. 2 Quote season snowfall: 34.8" '22-23: 30.2" '21-22: 27.1" '20-21: 52.5" '19-20: 36.2" '18-19: 50.2" '17-18: 39.5" Average snowfall: ~30" Link to comment Share on other sites More sharing options...

Hawkeye Posted January 10, 2020 Report Share Posted January 10, 2020 Welp, this is why you can't just throw out the GFS and hug the Euro.

bud2380 Posted January 10, 2020 Report Share Posted January 10, 2020 Well even the euro shows 6” for Iowa city. GFs 5, NAM 7, 3k NAM 10” and HRRR 5” even though the storm isn’t done. So up to 6” is still a real possibility Quote Link to comment Share on other sites More sharing options...

Hawkeye Posted January 10, 2020 Report Share Posted January 10, 2020 00z UK is about as expected. It's a bit juicier with wave 1, about the same with wave 2.

snowstorm83 Posted January 10, 2020 Report Share Posted January 10, 2020 6z NAM with 6-8" for Omaha/Lincoln. Last model I'm looking at for the night, bedtime for me. I get off work tomorrow at 4, so it could be an interesting commute. Right now it seems like Euro vs. GFS/NAM/RAP/HRRR.... Euro may be outnumbered, but that doesn't mean its wrong. 1 Quote Snowfall in Lincoln, NE: 2017-18: 21.4" 2018-19: 55.5" 2019-20: 17.6" 2020-21: 49.4" 2021-22: 5.1" Average: 26" Link to comment Share on other sites More sharing options...

bud2380 Posted January 10, 2020 Report Share Posted January 10, 2020 Long write up by DVN. Talking about where the sleet line will setup. That will make or break the forecast. Right now they think mostly snow northwest of Iowa city. Fingers crossed. 4-8” 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted January 10, 2020 Author Report Share Posted January 10, 2020 00z Euro....did the King just cave to the GFS/Ukie??? It's nice to wake up and see that Chitown is back in the game. I'm still not sold on it but won't lie that it is nice to see the Euro come onboard with a weaker and farther SE track for the main energy. I hope all of us can share in the wealth that are in the snow dept. As Bud mentioned, there was a storm earlier on in the season (Dec 14th-18th) that the GFS sniffed out post d7 and consistently advertised a snowstorm while all the other models played catch up. It was the storm that hit those members around KC and the MW/OHV region. I've been watching the consistency of the GFS/GEFS and that voice in my head said "there is a chance" the GFS may be right. With it being less than 36 hours before game time, I feel pretty good getting at least a shovel-able snow and making it look like Winter again. FWIW, the Euro Control followed suit to the Ukie/Euro/GFS and hits MO/IL/SE WI hard with the defo band.... 00z GEFS... 2 Quote Link to comment Share on other sites More sharing options...

ToastedRavs Posted January 10, 2020 Report Share Posted January 10, 2020 Spoke too soon about my county being in a warning, or even Des Moines. What an idiotic decision by Johnston NWS. Makes zero sense. They say that they don't think second band will make it to metro thus only an advisory despite 6 inch amounts and higher in grids. Frustrating and I will laugh at their stupidity when they have to adjust later this AM. Rant over And they clearly didn't coordinate or agree with surrounding offices. To be in on that conference call. 2 Quote Link to comment Share on other sites More sharing options...
