Hawkeye Posted December 12, 2020 Report Share Posted December 12, 2020 The latest HRRR run parks a heavy band over Cedar Rapids, and eventually Iowa City late tonight into Sat morning.

clintbeed1993 Posted December 12, 2020 Report Share Posted December 12, 2020 1 hour ago, CentralNebWeather said: Yes, very surprising. Basically sat over me for 5 hours now. Looks like several more hours. Local sheriff is advising against travel as snow is thick on the roads. I bet we see some 8” reports by tomorrow morning somewhere in the Central Nebraska area. I know Aurora has had at least 6 or 7, but it won't look like quite that much with the compaction. I drove the 3 hours from brown Saint Joseph, MO to my parents house to enjoy the flakes. It's been too long. This was a very impressive band of snow considering how far East the low is and how weak it is. Couldn't ask for anything more out of it. If every storm cooperated like this we'd be buried every winter! Love these Interstate 80 specials 1 Quote Link to comment Share on other sites More sharing options...

Hawkeye Posted December 12, 2020 Report Share Posted December 12, 2020 Like the earlier batch of precip, the new batch is not producing anything that will accumulate.

snowstorm83 Posted December 12, 2020 Report Share Posted December 12, 2020 Up to 2" now. Hopefully there's redevelopment because it looks like a dry pocket is about to hit before the back edge.

snowstorm83 Posted December 12, 2020 Report Share Posted December 12, 2020 Measured 2.75" as it's still coming down at a good clip. I've been looking at a still radar image so didn't realize the movement of the system until I looked at an animiation. I guess it's hanging around a bit, so I wouldn't be surprised to get another inch at least. 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...

Grizzcoat Posted December 12, 2020 Report Share Posted December 12, 2020 Mesoscale Discussion 1839 NWS Storm Prediction Center Norman OK 0119 AM CST Sat Dec 12 2020 Areas affected...portions of central and eastern Iowa Concerning...Heavy snow Valid 120719Z - 121315Z SUMMARY...An area of heavy snowfall is forecast to evolve over the next 2-3 hours, with snowfall rates around 1" per hour expected -- likely peaking during a 3-5 hour period from roughly 08-09Z through 12-14Z. DISCUSSION...Latest radar loop shows a zone of light to moderate snowfall occurring from eastern Nebraska eastward to eastern Iowa, with the current rain/snow line extending roughly from KLWD (Lamoni IA) to roughly KCWI (Clinton IA). This zone of snowfall is occurring within a zone of deformation north of a well-defined vort max -- evident in current WV imagery over the Ozark Plateau of southern Missouri -- which will continue moving east-northeastward with time and reaching central Illinois around sunrise. Favorable large-scale ascent will continue within the deformation zone as the surface low -- now over northeastern Missouri -- continues to gradually deepen as it shifts east-northeastward with time, in tandem with translation of the upper feature, and strengthening of the cold conveyor belt. With moist/saturated thermal profiles -- including within the favored dendritic growth zone -- an increase in snowfall rates within the deformation zone is expected, possibly aided by some weak convective enhancement given steep lapse rates and even some minimal CAPE hinted at within model forecast soundings. Snowfall should increase over the next 2-3 hours, and continue at around 1" per hour rates within the MD area for several hours, before tapering gradually from west to east through mid morning. ..Goss.. 12/12/2020 1 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 December 12, 2020 Report Share Posted December 12, 2020 This is really the perfect track of a storm for C.IA into E.IA. Been plenty of QPF- ( talking .70 or allready) about 1/3 has been rain. Winds stronger than forecast. ( trees trunks blasted -- see coming pic) "IF" cold air was entrenched N- this would've been a barn burner. Not being picky. I love it. 3 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.

Tom Posted December 12, 2020 Report Share Posted December 12, 2020 Woke up to the sound of rain pelting my skylight and wind driven rain hitting the windows. Reading through all your posts I'm thrilled that this storm is delivering the goods. Quite the moisture laden storm system. As a few have stated, this storm is going to be ear marked for future cycles. Just the perfect track, wind trajectory, moisture but all we are missing is the cold air. See you back in late Jan??? Anyhow, one could only think what "could have been"...congrats on the snow out west guys. Looking great for all of you in NE/IA and now into S Wisco later today. Local reporting stations suggests 1.40" of liquid thus far for mby....man, this would have buried Chicago...esp with the perfect wind trajectory to produce LEHS. 4 Quote Link to comment Share on other sites More sharing options...
bud2380 Posted December 12, 2020 Author Report Share Posted December 12, 2020 The last several runs of the HRRR continue to show very heavy snow for CR and Iowa City. Just need this to changeover. I wish I had slept longer. LOL. 1 Quote Link to comment Share on other sites More sharing options...
Grizzcoat Posted December 12, 2020 Report Share Posted December 12, 2020 For the record - again - GFS was miserable on this event. Chalk this in the archives for upcoming events. Euro ( and others) hails as KING-- (will probably see isolated 7"+ reports in C.IA, something the GFS had no clue, even up to the event. The GFS is certainly a "Perfect Stranger" when it comes to this event (and most) -- and for those that like this song- kudos to you. Awesome tune btw. For you youngins out there, this is some music you don't see today. 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.

bud2380 Posted December 12, 2020 Author Report Share Posted December 12, 2020 Yep the GFS was awful for this storm. It did a good job sniffing out storm potential up to 10+ days out. So kudos there but in terms of any reliable details of the storm it was atrocious. Like I said repeatedly the GFS has major thermal issues. I noticed it this summer and it continues now in winter. So a marginal temperature event like this it’s no surprise it couldn’t handle it. The 00z run shows 1-3” across the state at best. Dubuque is already well past that. 4 Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted December 12, 2020 Report Share Posted December 12, 2020 I just woke up to check. Of course, I'm in the middle of a dry pocket so the snow is very light. I'm not going outside now, but there's a report of 1.5" in CR and that looks reasonable. There's a batch of heavy snow east and northeast of CR. Hopefully, we can get into a bit of that by morning. The 3k NAM has the heaviest snow lifting up to the east of CR. We'll see.
