ILSNOW Posted March 14, 2017 Share Posted March 14, 2017 Starting to snow here in Buffalo Grove. Any Chicago posters have any thoughts on the lake effect. Seems like the HRRR brings a band into lake county the moves it pretty quickly into cook. Link to comment Share on other sites More sharing options...

Hoosier Posted March 14, 2017 Author Share Posted March 14, 2017 Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 850 PM CDT Mon Mar 13 2017 .UPDATE... 850 PM CDT No big changes planned to going forecast at this time. Lake effect snow has been blossoming this evening, largely consisting of multi-banded structure into NE IL and SE WI as the previously semi dominant single band over SE Wisconsin weakened. The array of hi-res model guidance is in good agreement in depicting strengthening low level convergence through the night with already favorable LES parameters actually growing even more favorable with time. Eventually, would anticipate this multi- banded LES structure to begin to transition back to a more dominant and intense single band, though how long that process takes to occur is the big question. Given recent observational trends, increasingly leaning toward a later development of the single banded structure, possibly not until closer to sunrise. The more multi-band structure should result in a more widespread snowfall, but likely less intense snowfall rates. Snowfall intensity/rates will increase significantly when single band eventually develops, with snowfall rates exceeding 2"/hour likely at that time. The later the transition to single band occurs, the likely farther east placement of the heaviest totals. Starting to look like the highest totals tonight into Tuesday could be across eastern and southern Cook County, though Lake County IL is not quite out of the woods yet. Have decided to add Lake Co IN into the warning as such strongly favorable parameters will likely keep the intense snow rates going through at least midday tomorrow with a good chance of at least 6 inches of snow in northwestern Lake Co IN and double digit totals not out of the question by late tomorrow afternoon. LES should begin to weaken somewhat tomorrow afternoon, but continue into tomorrow evening. Parameters tomorrow night again look quite favorable for heavy lake effect snow. While inversion heights will be somewhat lower and we`ll lose the added synoptic ascent, instability and low level convergence look stronger than tonight. We are far enough out that there is an urgency to issue any headlines for Porter Co, but this is something the midnight shift will likely have to contend with. Will leave the expiration for Lake Co the same at 06z tomorrow night, but that may be a bit soon and could need refining tomorrow. Will get updated WSW shortly, updated grids and forecasts will follow, though perhaps not quite as quickly! Izzi Link to comment Share on other sites More sharing options...

I'm in a mini-band currently but waiting for the "fire hose" IF it happens lol. Imo, I think the band dropping down from N Lake will restrengthen/combine with the current one affecting N Cook and become the main one around Lake and Cook Counties. Just my hunch Link to comment Share on other sites More sharing options...
michsnowfreak Posted March 14, 2017 Share Posted March 14, 2017 As of 7:30pm we had 5.3" here, Im sure we have picked up a few tenths more since. The powder has been blowing and drifting all day, roads treacherous, a real mid-winter scene a week before spring officially starts. Link to comment Share on other sites More sharing options...
cyclone77 Posted March 14, 2017 Share Posted March 14, 2017 ^Nice pics guys. This is the first legit lake effect snow I've ever seen fall here. I've seen a few flurries make it this far west before, but never anything more than that. It's coming down pretty nicely out there right now, and has re-whitened up the pavement. Pretty impressive little event. Link to comment Share on other sites More sharing options...

OHweather Posted March 14, 2017 Share Posted March 14, 2017 I'm impressed by the LES making it all the way into Iowa. That's decent (but certainly not unprecedented) inland penetration...what's odd is getting a favorable environment for LES and decent inland penetration on an ENE wind.

It has made it as far west as I have ever seen, closing in on Iowa City now, and likely will make it into NW. Missouri.And as you mention, it's definitely impressive with a ENE wind. Feeds off of Huron and Erie are helping though. Link to comment Share on other sites More sharing options...

CoalCityWxMan Posted March 14, 2017 Share Posted March 14, 2017 Snowing moderately down here ~75 miles away from the lake. Looks like a local cooling lake (braidwood cooling lake) is producing its own lake effect snow over a very localized area, according to some friends' observations Link to comment Share on other sites More sharing options...
Chicago Storm Posted March 14, 2017 Share Posted March 14, 2017 Looks like the main plume is finally congealing over the lake, with a dual feed from the length of Lake Michigan, also coming in from Lake Huron.High rates and rapid accumulation incoming, especially if it's not too transient.

Pretty impressive little event. Thanks! Lake effect is awesome. It has saved our winter here this year. Even this far away from the belts "mood flakes" are always there to give that winter feel when making nature won't cooperative synoptically. Storm total here 5.5" which is better than I expected. Looks and feels like the dead of winter. I'm very pleased. Link to comment Share on other sites More sharing options...
