The nam and GFS were right The Canadian once again was overzealous and blew chunks. I don’t remember a time when the Canadian wasn’t out to lunch. Never look at the GEM or RGEM for snow totals. They are always over cooked

I hope the greens fill in over me on the radar. Another 1" or so would be great to add to the season's tally....so far I think we’re sitting in a good spot right now.

Grass is almost covered in WashMO. Between 1/2”-1” on my patio table.

I’d estimate right near 1/2” here in VR.

Nice steady light snow at 8 degrees in Perryville. May not say that for another 20 years.
We may get an inch depending on the heavier stuff and it's ability to hang on an extra hour or two.

I think I will be forced to quote the great Maxwell Smart....."Missed it by <> that much" Still time, but it looks to stay just SW of downtown De Soto, and I mean JUST SW of me. We will see.

Sullivan looked to be the heavy spot on the news , the live shot showed much bigger flakes. They will likely be the 2” winners.

Just made the drive from Pacific to my home off 109 and the visibility is stank. It's probably less than a quarter mile on 44, as this dry stuff is blowing all over the place. On 109, we were going about 30 through the hilly area from Eureka High School up past the YMCA. After Manchester, probably max 40. Saw the road lines about 20% of the time. If I didn't know the roads intimately, I would have been seriously stressing. Saw a plow go by ONCE going south on 109. The side I was driving on was not scraped. Then he went down into a subdivision. Made no sense, how about the main roads first?
Temp 4, still lightly snowing.

Different jurisdictions. 109 is MoDOT and the subdivision is either Wildwood or private.

How's about a good teaching moment from some of you more knowlegeable one's on here. Looking at SPC Mesoscale Anaysis page, on the 'surface' map it shows us almost directly under the 1030mb ridge. What upper air charts can we look at that shows 'why' this snow is developing and occurring over us at the moment? The wind barbs at 925mb look to be perpendicular to the temp gradient but I can't identify any other specific reason. Anyone care to comment???

Then that means I didn't see MoDOT at all. Btw, this isn't about snow amount, this is more about visibility.

Looks like they will get about a quarter of an inch to half an inch
although it look like just a small dusting because the snowflakes are so small and fine that they're going under the grass and around it
unfortunately as we finally get under a decent band disabilities have dropped a lot here it's almost over

Trying to plow this can make the visibility worse. I like Jeffco's approach of using a sand/salt/liquid calcium mix for something like this as it tends to slow down the snow snakes and the blowing. However, it leaves a pretty good mess after the storm. Not a big deal on the chip seal roads out here, but probably wouldn't fly real well along that stretch of 109.

Not sure if I'll make an inch. Rates not impressive right now though roads look quite slick.

Roads are bad out here. This stuff is slick as snot and the snow is coming down the hardest thus far. Almost consider it moderate based on the flake size.

Just got back from McDonald's. Moderate snow here. Roads are poor. I'm guessing 3/4th inch so far.

This winter has been great.
But most of that was in one event.
And when you consider no blocking.
We are incredibly lucky so far.

I wouldn't be surprised if WNW of Farmington gets 3-4".
I'll call it a half inch here.

The wind barbs at 925mb look to be perpendicular to the temp gradient but I can't identify any other specific reason. Anyone care to comment??? Great question. There are two primary forcing mechanisms in play right now: DPVA (differential positive vorticity advection) and frontogensis. There may be some lower level convergence colocated with upper level divergence, but I don't think it's a major player right now. 500mb vorticity: The flow is perpendicular to the vorticity field. This is moving the spinning tendency in an area that has it to an area that doesn't. This induces lift. SPC 700-400mb diff vorticity advection: Same as above just using an SPC chart. SPC 700mb Frontogenesis: Frontogenesis is the process of tightening the temperature gradient. This induces lift. SPC 650-500mb EPVg: Same as above just through a different layer. Ignore the EPV part. It's not in play right now.

Post by guyatacomputer - NE St. Peters on Jan 30, 2019 19:11:15 GMT -6
Just got back from running from one end of St. Peters to the other, over to 40 and K and back to the northeast corner of St. Peters. Started before 5, stopped for dinner, and got home about 645. Funny thing is the roads that had enough traffic on them to blow the snow off were pretty good...until they started putting salt down. The lesser roads that were snow covered before they started putting down salt were starting to get a bit slippery. Once the chemicals started working on the roads it almost made the main roads more slippery because it was the mix of snow, water and even some ice and slush.
Also covering the entire length of St. Peters twice my car thermometer never got below 5 degrees. No car thermometers are known to run a couple of degrees high because of the heat of the vehicles. But not 7.
Sidenote: could not the believe the number of people running without headlights. Even as late as 530 when it was getting pretty dark. Just want to smack them..

There were runs where the nam and gfs printed out nothing.
The rgem may have broad brushed a bit, but it called the snow days ago as well as an enhanced band. I dont understand the hate
