Yeah, I feel like when I was a kid we almost always had a stretch like this in winter. I remember getting smaller-ish storms, and sled riding then followed up like every other day getting another 1-3 or 2-4 with snow on the ground adding fresh powder to our sled runs lol I'm sure my memory makes it seem more frequent than it probably was but this is the type of stretch I've been missing. Still wouldn't be mad if we scored a bigger storm somewhere along the way. :lol:

I think these stretches are still quite common in an average to good winter here. How else would we average 40”+ while whiffing on big storms.

Update focused on handling band of light to locally moderate
snow showers across the central CWA, in a band that likely has
its origins from WNW flow off of southern Lake Michigan. 12Z PBZ
sounding shows saturation through most of the dendritic growth
zone beneath an inversion at around 760mb. Many of the CAMs did
not handle this well, with the NAM3km nest being the one model
that has something close to reality.

This is definitely a more classic Pittsburgh winter, with many small northern-stream events flowing through the CONUS.  This isn't a big storm pattern right now - too much interference.

We generally want these things on our side: -EPO, -NAO, -AO, 50/50 North Atlantic low, but right now there's too much of each.

The -NAO is too far south.  The -EPO is way too strong and influential on the downstream flow.  The giant North Atlantic trough is shunting potential development.

It's a good pattern, in theory, but in practice we just have too much confluence and not enough southern influence.  If something like this setup in a moderate El Nino base state, I could see the potential.

Yeah, that's all time stuff we're flirting with.  I think that's the coldest model run I've ever seen for here.  At least we know that it's very unlikely to happen, lol.

Looking ahead i like this look as shown. -EPO with a little southeast ridge to help steer a storm up and not out. Looks good for overunning. Let's see how everything evolves. In the mean time we have 1-3 to look forward to for the weekend.

I don’t know - it’s thumping pretty good here relatively speaking. Pushing an inch and it really just started here around 7:30. Roads covered. Snowpack freshened up .Nice night overall. 

Well yeah the radar shows all the better bands right at the county line. Seems like you will verify the higher amounts and points south will get the 1-2. Enjoy it. I'll take it since I'm at work.

Light snow is starting now. That snow hole (dry slot) that was showing on all the models has held tight for the last 2+ hours. 

Yeah, I was a little worried several short range models showed that better banding NW of the city. Some areas already with 2-4 on the ground that weren't even in an advisory until they just recently upgraded. Still need to see how it plays out but nothing but a few flurries here so far. Probably will be lucky to get much more than an inch.

Well, doing nothing in the City, so it’s unfortunate.

I've seen nothing but flurries. A tad frustrating. Even though it's a small storm that radar is a bit much.

Yeah I get that. This is a frustrating hobby. This is when I'm glad it's happening at night so we don't miss out on heavy snowfall during the day.
