If you loop through the runs, it looks like the GFS is progressively getting weaker and weaker for the Sunday thing. Couple that with it not showing on any other guidance and I think we know how this will go.

NAM gives the area 3-4 inches but still 48 hours away. 

With the winds it and fluffy nature of the snow, it's going to be blowing and drifting around too. 

I'll be curious to see if we get any squalls later Friday night.

Next weekend looks like major potential. EURO on board.

Models are all over the place on late next week, something I have issued a big storm watch for the NE on Weatherbell based on studying pattern analogs and concluding a blend of 3/29/84,12/10/92,02/09/69 and 02/13/ work best. So the surface map for that gave me this for day 11, New euro went to it. So, like the storm a couple of weeks ago, where using 3 analogs gave a great solution a week out ( not perfect, but dang close), I started looking at this 5 days ago. The question then becomes, DO I HAVE THE RIGHT ANALOGS? But that means I am in charge of the idea, not the models ping ponging me. So you put out the idea and then wait and see if modeling comes to it. But it's not based on the models, it's based on pattern recognition and then doing the work to go back through all those maps and try to get the right package. This is how they did it in the old days, when 4 runs a day of computer models did not force a ping pong match among meteorologists. SO I RELY ON MY SKILL, NOT THE MODEL IN SETTING THIS UP! If you just look at models until a few days before you can get whip sawed, or you simply get on TV and say the models says this or that, and all you are is instead of a forecaster is a model spokesperson. The risk? That you do all this work and are wrong, and it's happened to me many times. But I would rather work and risk than outsource what God gave me. And besides, Bocelli is right in Un Nuovo Giorno: Solo rischiando tu vivrai. Only by risking do you live

Too bad Lake Erie is frozen over, but hopefully the front passing can stir up some nice squalls.

If models were a buffet...

I'd take a side of GFS for this weekend, scoop of the UKMET for midweek, and for my main course I'll take the Euro for next weekend. 

Once the desert cart comes around for late feb / early march, I'll see what I want off of that.

12z Euro and 6Z GFS loving next weekend. 12z gfs south.

Interesting to see what unfolds over the next (gasp) 10 days. But the signal is there.

KEY MESSAGE 1...

An Alberta Clipper will track through the Great Lakes and bring
another round of snow to the region Friday morning into early
Saturday. In general, forecast values across the lowlands
average around 2.5 inches, with localized areas measuring as
high as 4 inches. Peak times for snow accumulation still look
to be between 10am and 5pm, which will likely impact the Friday
evening commute. There is very little uncertainty about the snow
type; it is expected to be light, fluffy snow, with snow-liquid
ratios ranging from 18:1 to 21:1.

Higher amounts are likely in the ridges with enhanced rate due
to upsloping. 3 to 6 inches are currently expected with locally
higher amounts possible. Blizzard conditions are also possible
given the character of the snow and eventual wind gusts
up to 45mph. In coordination with surrounding offices, a Winter
Storm Watch was issued for the ridges of WV and PA.

In the evening, an advancing cold front may result in another
period of increased snow rates, and possibly snow squalls. Be
prepared for rapidly crashing temperatures into the single
digits, gusty winds, and low visibility if snow squalls develop.

I kind of wish the models waited until Day 4 to show something.  I was doing so good with sleep and not watching 0z models as they came out. Now they are sucking me in...

10 days haha Here we go again. Time to reel in another big one

[colonel717]

What a disaster that GFS run was. 4 inches of rain next week would cause major flooding with ice jams next weekend. Thankfully it's still 10 days away and it's  the GFS...

Is it just me or is tomorrow’s clipper looking a bit more meh as it approaches? Like closer to 1” rather than 2 or 3 if we’re lucky?

[TimB]

Just feels like there’s still a very real path to snatch defeat from the jaws of victory and somehow fall short of normal annual snowfall despite already being at 36” for the season as of 1/25.

Stop it.

Have a nice snow shower. Everything whitened up.

At this point, even if it falls below, this is season has exceeded my expectations and has been fun.

I mean the HRRR has us for around 2 inches. I dont know what people were expecting from a clipper with no real gulf involvement. We are 7 away from average. If we get two thats 5 away. I think we should make our average with basically all of February,March and April left.

Getting this light but fluffy snow. Kind of unexpected.  Because there is zero wind, it’s sticking to the trees like a wet snow. Snow globe morning.

No real lake involvement either. Clippers end up nowcasting events. 2 in is usually where I set my bar for a clipper.

Is the airport really that low on their total this year. I am at 41.2 IMBY and I likely missed counting a few of the smaller .1 -.2 type of snows.

Yes they are really only at like 37.

Wasn't there a day in early decemeber where a thin snow band dropped several inches along the southern AGC border, but totally whiffed in other parts of the county? -- might explain at lease some of it?

[Burghblizz]

I got about a fluffy half inch on trees. The wind kicked up slightly and started blowing some snow. Because the snow is so fluffy it’s actually coming off the trees as individual flakes. Almost like a mini squall. Not sure I’ve ever seen that, but a cool effect adding to scenery.
