12/28 - 12/29 Plains/MW/GL's Snow Event

[bud2380]

Tom do you get the Euro data from a pay site? I see Ryan Maue started his new site weathermodels.com this morning and the good Euro maps are no longer free. That sucks.

I’m still able to access the Euro on wxgraphics. Here is the Euro

Looks like GFS

-SN flying in the north burbs of Chi...I’m currently in Long Grove and it’s a nice mood setting snow.

[hlcater]

Real nice band swinging through right now. Moderate snow with the best dendrites I've seen from this system with visibility between 1/4 and 1/2 mile. Looks like it should taper through the rest of the day afterwards. Probably have 0.8-1.0" so far, about on target.

This.  This last band is dropping the kind of snow I love to watch.... medium dendrites coming down pretty good, no wind.  I wish all snow could be like this.

[shakjen]

Light snow just started here.

[Tom]

Radar looming good for N IL...High Rez NAM had this and looks good to me...could score 1” today

Radar does look nice to the west. 

 

LOT update for Friday. Hoping for 2-3

 

In the area of

heaviest totals, wouldn`t be surprised to see snow:liquid ratios

at or above 20:1. Generally thinking a 2-4" snowfall from I-88/290

south tapering to an inch or so along the WI/IL border. Wouldn`t

rule out isolated totals up to around 5" along/south of the I-80

corridor, particularly if f-gen circulations are stronger/deeper

than currently progged or if SLRs end up higher than forecast.

Quick hitter!

[dubuque473]

Yeah, I’m assuming you’re still kno dubuque, because id say the same. Don’t know if accumulations have been anything super special, but it’s been nice to see snow falling at least.. and without causing major issues on the roads.

Yep still in DBQ. Radio says should snow til 4pm. I assume we have a solid inch but I havent been out since 9am.

[james1976]

NAM looks solid yet

[bud2380]

18z NAM shifted south from the 12z run and is now in line with every other model. Looks like I got an inch today. Snow came down pretty good at the tail end.

[james1976]

I wonder if they issue headlines soon

[james1976]

It will be daytime snowfall so that will be cool.

[Tabitha]

 the good Euro maps are no longer free.

 

Since that model always shows the worst possible solution; I consider their removal addition by subtraction...

 

What you don't know can't hurt you...

[Tom]

If Chi can score and inch today and 2-3” mañana, I’d call it a good 2-day event.

[Iowawx]

Almost positive that a winter weather advisory will be issued within the next couple of hours. Looking like a widespread 2-4 inch event here. Maybe higher totals possible.

[Iowawx]

WWA issued for eastern Iowa. 2-5 inches expected.

[hlcater]

Advisory hoisted.

 

 

 

WHAT...Snow expected. Plan on slippery road conditions,

including during the evening commute on Friday. Total snow

accumulations of 2 to 5 inches are expected.

 

* WHERE...Portions of east central Iowa, northeast Iowa and

southeast Iowa.

 

* WHEN...7 AM to 9 PM Friday.

 

* ADDITIONAL DETAILS...Be prepared for reduced visibilities at

times.

 

[East Dubzz]

Not totally convinced we’ll see 2” up here inn DBQ, but we shall see.

[Minny_Weather]

The idea of not getting anything would be much less frustrating if every model didn't have moderate snow fizzling right as it hits my county.

[Yerf]

Under a good snow band now! Very wintry. temp at 12.

[Hawkeye]

I woke up to little more than a dusting as the first part of today's wave crapped out, but that tail band dropped a nice inch of fluff.  My liquid total was 0.05", so the 20:1 ratio panned out this time.

[dubuque473]

Just wont stop today! Nice to watch. Glad to see a WWA out ft or tomorrow.

[Tom]

Under a good snow band now! Very wintry. temp at 12.

I agree! Been on the road all day and the snow is blowin around very easily. Love these fluffy snow events. Event though I’ll prob come short of an inch, it’s still a pleasure to see.

[hlcater]

Feels amazing to have this back in the forecast. I can't remember the last one.

 

[Madtown]

my home weather station calling for heavy snow....so close...actually pretty impressed that it distinguishes light snow and heavy snow. enjoy it down south.

[Craig-OmahaWX]

Just checked the HRRR and it is dangerously close to Omaha with the shield of snow, seems like it came a tad south. It is only a county north of here so will keep an eye out for any southward movement.

Loval met goin with 3-5 with local 6 by CR and IC. Hawkeye and Bud may be in the bullseye finally. Im hoping to get 4up here.

[james1976]

I added another .6" today so my total from last night and today is 2.2". Very happy how this panned out.

[james1976]

DMX:

Soundings showing decent deep moisture located across the central

and northern portions of the state. Area of frontogenesis to

stretch across the northern forecast area, with a band of light to

moderate snow expected in the vicinity of this area of lift. Best

lift situated along a line from near Spencer southeastward toward

Algona and Fort Dodge, toward Clarion, Marshalltown and Waterloo.

Cross- sections indicating decent lift in the dendritic-growth

zone (DGZ) with much of the column located within the DGZ given

the cold air in place. Therefore should see a fairly dry-fluffy

snow and higher SLRs in the 15/20:1 range.. Concerns center around

QPF and snow ratios, as models have been trending wetter with

this system over the past 24-36 hours with a few models indicating

around 0.15 inches of QPF possible. Some concerns that QPF may

end up being a tad higher, or SLRs higher and could push snow

amounts up a bit. Therefore currently have snow amounts in the 2

to 4 inch range where heavier banding expected. Concerned that

slightly higher amounts may fall in spots, and given the likely

high travel weekend, and still a snowfall early in the season will

issue an advisory even with marginal snowfall amounts.

15Z SREF plume for Cedar Rapids shows a 4" average.  A high of about 7", low of basically 0. 

 

[Tom]

Radar showing nothing overhead but light snow is falling. Almost has that “misty” look to it. Very fine and dry flakes.

[bud2380]

NAM shifting north again.

[GDR]

[bud2380]

I wouldn’t trust the NAM at all. All other guidance is further south including recent runs of the RAP and HRRR
