snowstorm83 Posted December 30, 2021 Report Share Posted December 30, 2021 EPS has ticked south and is a tad weaker. Could go either way for Omaha/Lincoln at this point depending where models decide to shift tomorrow.

clintbeed1993 Posted December 30, 2021 Report Share Posted December 30, 2021 Might be the first snowstorm to target my new place in St Joseph, Missouri! Most models have me in the jackzone.

Clinton Posted December 30, 2021 Report Share Posted December 30, 2021 My first Winter Storm Watch of the year. ...WINTER STORM WATCH IN EFFECT FROM LATE FRIDAY NIGHT THROUGH SATURDAY EVENING... * WHAT...Widespread wintry precipitation is expected across the region. Total snow accumulations of 2 to 8 inches and ice accumulations of around one tenth of an inch possible. Winds could gust as high as 35 mph. * WHERE...Portions of east central and northeast Kansas and central, north central, northeast, northwest and west central Missouri. Highest snowfall totals likely along and north of a St. Joseph to Chillicothe to Kirksville line. Greatest ice accumulations likely along a Butler to Sedalia to Boonville line. Snowfall totals across the KC metro look to range from 3 to 6 inches. * WHEN...From late Friday night through Saturday evening. * IMPACTS...Travel could become very difficult. Patchy blowing snow could significantly reduce visibility. * ADDITIONAL DETAILS...Very cold temperatures and wind chills Saturday and Saturday night will impact vulnerable populations as well as make travel more dangerous in the event that you become stranded in your vehicle. 1 1 1 Quote Link to comment Share on other sites More sharing options...

Ya, maybe the dense arctic air will press it farther south...the trend among the ensembles appears to be heading that way...I don't like how the secondary energy disconnects on the Euro...hopefully it can correct it in the coming day or so. 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted December 30, 2021 Report Share Posted December 30, 2021 0z EPS members showing it really gets going around dinner time New Year's Day for N IL...if the timing holds, the snow should begin to fall around Noon. Gotta say, I'm getting a bit tickled with excitement and the fact that this storm is hitting on a holiday weekend and during the daytime is an added bonus. Another added bonus is I'm seeing the models picking up on a Lake Plume developing out ahead of the main event. In a similar fashion, the Blitz of '99 started out the same way iirc. This system is a much different set up but the timing on New Year's makes this all the more enjoyable. 1 Quote Link to comment Share on other sites More sharing options...

Tom Posted December 30, 2021 Report Share Posted December 30, 2021 06z Euro... Pretty much every model is showing somewhere around .70" qpf for Chicago and adjacent counties.

tStacsh Posted December 30, 2021 Report Share Posted December 30, 2021 yikes it went south and much weaker for snowfall here. Oh well 3-4" of colder fluffy stuff is what I figured and looks like that's what I'll get. Hopefully it scoots about 50 miles north of where it's projected, but the trend is certainly south. I will say Radar returns always seem to go a few miles north of any model projections. Every time I'm in the sweet spot right before an event it ends up north of here. 1 Quote Link to comment Share on other sites More sharing options...

I recommend following his Facebook page, he has multiple videos on this question. He’s an old school guy (before reliance on weather models). He came up with “Barbs Rule” (who is his wife haha) many years ago which ultimately says 3 days prior to event, step away from models and begin monitoring things like surface track and trends, checking out different NWS agencies where the storm is currently located for their local observations, etc. After 7 consecutive EURO runs followed by 12z GFS coming more in line with it yesterday afternoon (72 hours out) no more models. He even predicted yesterdays evening runs would shift their track. Has this method failed over the years? Yes. But I’ve followed him for 15 years now and he wins more times than not. You can use the updated 12z NAM as an example of this method. Quote Link to comment Share on other sites More sharing options...
FV-Mike Posted December 30, 2021 Report Share Posted December 30, 2021 Wording from LOT should make Chi folks get a little excited. The big picture, as has been detailed the past few days, offers some classic components of a winter storm synoptic patterns for the area. This includes a surface low tracking near or north of the Ohio River while an expansive and strong surface high is present over the Plains. Subtle variance in key mass fields aloft will serve to modulate the pattern in ways that will lead to additional refinement. What there is increasingly high confidence in is that a sizable portion of the CWA, including the Chicago metro) resides in the "threat zone" for 6"+ accumulations. This is due to: plentiful available moisture in the developing TROWAL (trough of warm air aloft); good dynamics (favorable jet forcing and strong PVA); and likelihood of mesoscale banding from frontogenesis due to sharp baroclinic zone over the area, augmented by presence of steep upper level lapse rates (neutral to weak stability favorable for enhancement of precip rates in the banding, such as occurred over Chicago`s northwest suburbs Wednesday evening). 2 Quote Link to comment Share on other sites More sharing options...
