To me... the upper level features on the Euro this afternoon do not line up with the surface features. I will guess the later runs will again shift south.

In the last 10 years, there have only been 2 winters with snowfall totals above 20"! Winter of 2012 to 2013 would have been over 20" with the Palm Sunday Storm (March 24, 2013) sealing the deal. |

I'm keeping it Positive!! It will Snow...that is all..actually I'm all in on Snow..but the Cold Arctic Hammer on the Euro and GEM at end of the runs..is insane..1057 hp..GEM, 1050 Euro..or close too it..as it enters the Pacific NW the anomaly is -50 plus degrees unbelievable if it materializes can you imagine the media Polar Vortex talk then..GOT.."Winter is Coming"

I really hope this doesn't end up like that storm last year that bombed out over the benchmark and sprayed us with heavy cold rain. That's a distinct possibility. It would be nice to have an unmitigated path for the cold air to take. The reality is though that from source to destination is brown. Some of it coming across an area that is still seeing a significant drought. That is concern #1 for me. However, that is mitigated somewhat by a vertically stacked system, so the ability of the storm to create its own cold is a bit greater IMO. As with any storm the last five years, there will be distinct winners and losers. Personally, I think the Godfrey area will be on the southern most portion of the snow, potentially even up to the northern counties of the viewing area. Those east of the metro better be preparing themselves for a nice cold rain, myself included up in SPI, IMO. QIN and COL seem safe at this point. All of that said, a slightly weaker or stronger system will be the determining factor I think. Stupid phasing. Just my .2 cents at this point. Trying not to get caught up in finer details right now. Yeah the snowfield doesn't look good. |

12z GEM was quite far south. Looks like a battle between the GFS/GEM and the EURO/UK?? Split down the middle might be the best approach. Ya usually one side caves to the others. Or they have a agreement in the middle somewhere. Which to me an agreement in the middle doesn't happen as much as the other outcome. |

Lots of snow bunnies north of us are starving. No reason why we would get to eat before them

Marginal temps typically ends up biting us. When people talk about late rain changing to snow, melting and compaction, many people will be disappointed with such a large storm and what could be lots of snow if temperatures were below freezing. Good thing is time to sort out all the details over the weekend. -cigar

Seems like we had at least a couple storms last winter that were modeled at this range as being vertically stacked and they came into more of a classic GYB configuration. And they tended to trend S/weaker with time. |

18z gfs wobbled back north of 12z.
Has the narrowest “death band” dropping incredible amounts of snow through Lincoln county.
Cutoff this run is basically St. Charles.

But I'd be good with that. Lol Point is models are coming in either north or warmer or both. So the trend is not in our favor. I'd imagine this will be the trend for next 24 hrs or so. Then praying they'll adjust back in our wheelhouse. |

The stronger the system becomes means it's more likely someone is going to get dry slotted (caught in no man's land) on the deformation side of the system. That wouldn't be good if the majority of the WAA portion of this system could be rain (yes some wet snow too). I cherry picked a sounding and it's way too close for comfort. The high over the northern Rockies needs to shift further SE. I'll gladly take a flatter and weaker system relatively speaking if that means we don't get hosed with rain and then dryslotted. Luckily it's only Thursday. As others have said, once we get to Saturday we can start adding true confidence to the forecast.

Ggem was way too south. |

This run of the GFS pretty much stinks ……. We went from Jackpot to nothing on this side of the river ……. It’s insane how we have to beg for snow around here anymore

I forgot the stages but RELAX. The overall setup still looks good for an impact storm. The exact placement of heavy snow at this point isn’t everything. If on Saturday things do not look great for your particular location, then we have issues. Saying all this, I also live model run to run lol

After looking at today's runs, I still think we're in a decent spot at this range. The GFS seems to be a nice compromise between the EC(north) and GEM(south) and the GEFS is just a bit north of the operational run but still supports some backside snowfall in/around the Metro.
The GFS has a considerably stronger surface ridge across the top of the ejecting storm, so we need to keep an eye on how that trends the next few days.

GEM ensemble mean is about perfect with a 995mb SLP crossing the benchmark and the 500mb low lifting across SE MO/S IL. The EC is pretty well on it's own currently which is good.

Glenn being real aggressive with his wording, talking about preparing for snow days on Tuesday. Slippery slope, no pun intended.

At this range, I’m just glad the models still have a storm. Rain, snow, sleet, ice, or anything. I still remember the days where at this range a storm placement would move 3-500+ miles. |

This system is definitely living up to the billing of "interesting" I just peaked over at the 12z Icon... and it is very slow pulling this thing together and really doesn't bring snow into the area until Tuesday night. But does show an narrow, but impressive looking band setting up over eastern/southeastern Missouri. In some ways... this system reminds me of the March 2008 storm that exploded right on top of us...with that super narrow mesoscale band that dumped 10 inches in a little more than 2 hours at my place in Chesterfield. Easily the heaviest snow I've experienced as an adult. I think it was this one... www.meteo.psu.edu/ewall/NARR/2008/us0304.php |
