WinterStorm294 Posted January 27, 2019 Share Posted January 27, 2019 Euro shifted the heavy snow about 30 miles north in SEMI. Still have hope for a south shift but worried about getting dry slotted like the NAM shows. Link to comment Share on other sites More sharing options...
mimillman Posted January 27, 2019 Share Posted January 27, 2019 Given the 12z Euro, I don’t think there’s enough support for LOT to shift the warning area south. Link to comment Share on other sites More sharing options...

We must have got close to 4" in my neighbourhood this morning. YYZ officially reporting 4" on the nose from last night. Honestly, it may be tough to beat that tomorrow. This ul energy sort of blows its load over the western lakes, and we're left with the scraps as it dissolves into the descending PV. Could get some lake enhancement though early on. I'd go with 3-6" for tomorrow. The more contribution from Lake Ontario, the closer we get to the high end of that. Link to comment Share on other sites More sharing options...

I think there good. Though there has been a trend south as the GFS came a touch south, and the Euro (which was a south outlier) a hair north to reach a consensus track just north of me.

Wind impacts = Blizzard headlines correct? Believe we are supposed to get some wind with this but not enough to meet criteria? I’m right on the LOT 4-6/6-8 line and the timing of this is going to be awful for AM commute and school. Link to comment Share on other sites More sharing options...

From LOT's aviation update: "very little change from previuos thinking" and that's Izzi who is a master at making changes. Link to comment Share on other sites More sharing options...
ILSNOW Posted January 27, 2019 Share Posted January 27, 2019 MKE update National Weather Service Milwaukee/Sullivan WI 1200 PM CST Sun Jan 27 2019 .UPDATE... Most of the 12z suite of model output is available. The biggest differences of note are the RAP/HRRR/ARW/NMM being northern outliers with the surface low track (across southern WI), while the NAM/GFS/GEM/00z ECMWF move the low across northern Illinois. Always challenging to have such differences this close to the event, but the do dictate where the heaviest band of snow will set up. Ensemble means still ride the state line at this point. Will continue to update QPF/Snow totals early this afternoon with updates out shortly thereafter. && .AVIATION(18Z TAFS)... Major winter storm will affect the region tonight and Monday. No major changes to snow start time, beginning roughly 01-03 UTC over western portions of the area (MSN) and 03-05 UTC over the eastern half of the area (UES/MKE/ENW). One to two inch per hour snowfall rates are possible late this evening through the overnight hours. Biggest change to the forecast was to keep snow longer during the morning hours, ending by mid afternoon. More tweaks to the end timing are likely. Expect IFR/LIFR with the heavy snow overnight, gradually improving late Monday morning and afternoon. Link to comment Share on other sites More sharing options...

However... this isn’t your average storm. And I should also add that there is absolutely no consensus on the SREF plumes - literally shows anything from 0.5” to 12.5” with no tightening to show a slight agreement. NWS’s have their work cut out for them again on this one. Same story of this season - we ride a last-minute edge here! Link to comment Share on other sites More sharing options...
Chicago Storm Posted January 27, 2019 Share Posted January 27, 2019 Kind of the opposite I thought would happen given 12z guidance trends, is for the 12z ECMWF to come a bit north.. Link to comment Share on other sites More sharing options...

Glad we got a good surprise snow last night because I expect to be on the lower end tomorrow, still should see a good thump though. Link to comment Share on other sites More sharing options...

Chambana Posted January 27, 2019 Share Posted January 27, 2019 I’ve been constantly reminded over the last 4-5 years just how terrible our snow climo is. Fully expecting to lose snowpack tomorrow as temps rise 35-36 degrees with a howling wind. Congrats to Chicago and the crew up north. Link to comment Share on other sites More sharing options...

hawkeye_wx Posted January 27, 2019 Share Posted January 27, 2019 The latest HRRR has come up a bit to 0.25" in Cedar Rapids, which is also what the Euro has stabilized at, so that's probably a pretty good guess. I think the 0.50" GFS and GEM are out to lunch. Link to comment Share on other sites More sharing options...

Yeah hopefully they continue to back off. Either way, it should be the biggest snowfall of the season here so far. And we'll have a fresh snowpack which should help to maximize the cold.

Certainly not your normal every day low pressure. Most do have the low riding along the IL/WI border and then along the I-94 corridor ending up north of Detroit. One thing is for certain. It will snow and it’ll be heavy for a few hours. Link to comment Share on other sites More sharing options...

Still a nice 3-5" event though, if we can get LSRs over 13:1, which I think is possible. Link to comment Share on other sites More sharing options...
sokolow Posted January 27, 2019 Share Posted January 27, 2019 For IMBY and surrounding personally am split on whether 3”-5” of snow trailing to crappy near freezing rain vs. 6” plus pure snow — followed by getting thrown into deep freeze for the rest of the week — which of those options blows our projects to hell worse Probably the former is worse Link to comment Share on other sites More sharing options...
