I did not bring it back up although no issue with verifying what was said previously now that the system has passed that's what a great debate should have:

"so much for that slop fest with an inch..". "

and i did see your original post. Unfortunately, while I love snow as much as anyone it gets a little crazy when people are told to leave the forum because they are not jumping on the hype machine or attempt to bring a realistic view to the table. :weenie:ism at it's finest. Oh and after seeing the new GFS have revised my call for Chicago area little to nothing west of I-294 but the longest lake effect event on Chi town history from Friday through Sunday. We may not hear from Aleking until next year as that's how long it will take him to dig out ......:snowwindow:

Unfortunately IND's WWA would have verified much better if they would have started it earlier and included the snow. By the time the WWA started, all accumulating snow was out of their CWA. I know the WWA was mainly for the threat of "freezing drizzle/rain" but from a public standpoint, the snow was just as much a hazard as any icing that occurred, and many locations flirted with advisory criteria. Definitely not a great forecast, but we all have them, and the models (which consistently dried things up across Indiana) were no help. Just my two cents.

Nobody should be telling you to leave. I think the main disagreement stems from the "slopfest" terminology. Let's take a look at Chicago's obs throughout the event. We'll even use Midway since that would capture any urban heat effects a little better. It was 24-27 degrees throughout the entire snow event, 28-30 with several hours of light freezing drizzle and right now it's 31. Saying something is X doesn't make it so. We can call 85 in July a heatwave but of course that really wouldn't be a fair statement.

Totally agree.

Baum - I never implied you were unwelcome...just wanted to explain why your posts sometimes get the reactions they do.

Anyway - a nice event for Chicago metro...some great snow rates for a couple hours last evening. :snowman:

Snowfall gradient from SW (heaviest) to NE (lightest), the exact opposite of the map LOT ran with until late afternoon. Pretty sure we were just shy of 3" here. My 2.5" call was decent.

It was certainly a WWA worthy snowfall here, even without the FZDZ threat. Of course even though the advisory started at 1:00AM, they had it up ahead of time. For the public's perception, I'm not sure the majority even look at the start/stop times...but I could be wrong. Of course technically speaking, it was probably better served to start at 7PM last night, or thereabouts. And mind you it's no slam against KIND by me...just Monday morning quarterbacking. Tough storm though.

It looks like 1-2" tops of LE and that's being generous.

Certainly seems to be the pattern with these type of systems so far this December. A very interesting one at that...no doubt a product of the blocking, etc.

:unsure: Hmm...wasnt it Feb? The entire southern half of MI (i thought) was blasted with record or near-record snowfall in Feb. There was almost nothing to write home about on Christmas break other than some light snow (unless you mean LES)

Good afternoon....Not where I'm at. We were right on the edge of all the systems (managed to get in on one of them) and had one lake effect event for the month. Over Christmas time last year there was a front that moved through with enhanced snowfall from the lake...and then there was a lake effect event. January was as boring as this month has been...and then like I said-February was boring as well (two small events). The Grand Rapids area to the south and east did much better.

In response to your post to WestMichigan below, it has been BAD here. We couldn't even manage more than a dusting of snow from last night's event. Pretty much everything has fallen apart over Lake Michigan this year (including the thunderstorms from the summer). I hope you're right about us doing well by the end of the winter. However, I have my doubts...

Not what i was expecting for this winter, especially early, given the med-range winter calls being put out, but i guess there's a reason i find those boring. Hopefully we transition into a better pattern with a little better blockbuster potential. I have a great string of winters featuring double digit events that i don't want to see die.

Sorry Beavis I was referring to this from earlier in the thread. Your post was more then fair and understood.

slop fest in Chi-Town....from LOT:

"SHOULD SEE RATIOS

DROP TO PERHAPS 8 TO 1 AS THE SNOW ENDS TUESDAY MORNING."

still thinking a quick 1-3 inches and then drizzle fest. Most of it can wash down the drain.:popcorn:

"ya...it doesn't say slop fest anywhere in that AFD...if you want to poo poo systems go do it somewhere else, yes there is a chance for frreezing drizzle at the end.".. Thundersnow

You are correct Hoosier...I'm headed out to shovel my 4 inches of slop :thumbsup:

Managed 3.75" of snow from this event, measured before I went to bed last night.

Woke up to find the new snow coated with about .02" of ice glaze, so some of the freezing precip did verify. After allowing for compaction from the liquid preicip we have just under 3" of snow for this event.

You guys were definitely the bread-winners in MN. Sounds like my 3-5" forecast for you was a massive fail arrowheadsmiley.png

Yeah, this has been a very nice hit. The snow just never quits. Intermittent moderate snow this evening. It's been snowing at about 1/2" an hour.

I saw 5 flakes today...

Thats 5 more than I saw. No fog either. Just very, very gray day. The kind of gray where I was looking outside and the white snow on the roof and the gray sky made a very noticable contrast (whereas on a regular cloudy day the two might blend right in). At least the snowpack is still not budging. I officially have a new respect for water-laden snowfall lol.
