Hawkeye Posted January 29, 2021 Report Share Posted January 29, 2021 Now the GFS says barely any snow at all in Cedar Rapids. Other models crash the snow down to the Missouri border by 00z. The GFS still has rain up to Cedar Rapids at midnight. It even pushes rain up to Chicago. Even the warmish NAMs think the GFS is nuts.

Bellona Posted January 29, 2021 Report Share Posted January 29, 2021 I guess I'll hold on to the short term models right now. I'd still be ok with 4-5 inches but I'd like to hit that 7.1 so we could break the record. Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted January 29, 2021 Report Share Posted January 29, 2021 Euro is doing the same thing as the UK.

Tom Posted January 29, 2021 Report Share Posted January 29, 2021 00z Euro...the consistency has been rock steady for N IL over the past few days. The only difference I see as we get close is the model is a tad colder at the onset when the initial front end thump of snow happens. It's suggesting nearly 9" for ORD in 6 hours, thus, the increase in totals for this run and better Lehs/LES on the backside. @indianajohn @Hoosierthis looks like it is coming together for you guys in IN... 00z UKIE... 00z EPS...steady as she goes... 3 Quote Link to comment Share on other sites More sharing options...

Grizzcoat Posted January 29, 2021 Report Share Posted January 29, 2021 It's very slight, but maybe a trend in that nearly all the 06Z guidance has slowly increased totals back W across C and W IA after going the other way yday. It will be the difference in placement in TOP 5 for Waterloo and Des Moines for snowiest DEC/JAN on record - in DSM's case it's either going to end up 3rd or 2nd.

bud2380 Posted January 29, 2021 Report Share Posted January 29, 2021 So far the NAM, 3k NAM, HRRR and the HRW suite of CAMS are all coming in warmer and further north this morning. Drastically cutting into snow totals for Iowa City and Cedar Rapids. 1 Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted January 29, 2021 Report Share Posted January 29, 2021 The NAMs have changed drastically just from 00z to 12z. The precip shield has veered east and south, but also the snow has pulled back north. Jim Flowers was banking on the NAM's scenario of Omaha getting a few inches, but overnight the NAMs totally removed all precip for that area. Unfortunately, it's not just the NAM that's crapping out for many in Iowa. The HRRR, which was colder and all snow for my area, is now warmer and drops the best snow north. The HRRR now has four hours of freezing rain and sleet in Cedar Rapids. Ugh! This system was locked in just a day or two ago, but it's fading now. 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 29, 2021 Report Share Posted January 29, 2021 12z RDPS is actually back up with snow for east-central IA. It shows a quick change to snow for the area, much quicker than the CAMs. I'm afraid I can't buy this colder look.

bud2380 Posted January 29, 2021 Report Share Posted January 29, 2021 Well, all winter the cold air has won out in my area, hopefully it will one more time. I hate to say this, but the models are trending towards the GFS. I will never issue the GFS an apology though. It's been wrong so many times. And could still be way wrong with this one as it is at major odds with the Euro still. Although looking at the Euro trends, it has changed dramatically from just a couple days ago. I can only hope the changes are done and it's locked in now. Quote Link to comment Share on other sites More sharing options...

The models always show lake effect being a lot more widespread than it ever really is. Especially on the west side of the lake, we get these short, narrow fingers of LES that move around. I might get 1-1.5" extra in my location if the snow ratio is high enough and the storm is slow enough. Interestingly, Skilling said Chicago's largest LES event (I presume non-storm-related) on record was only 5.5" in like 1992. Contrast that with the south and east shores where it can be significantly higher. Hard to say how much LES we get in blizzards though where there's a lot more going on. 1 Quote Link to comment Share on other sites More sharing options...
