Classic

Decent little system this evening. Another band entering PA, should give northern Allegheny county some decent rates.

Have to see if the NS vort hanging back a bit becomes a trend, or just a momentary blip.

I think I had more days off that school year, than all the rest combined. Lol.

A true I-79 classic.

Wow, don’t see those speeds too often.

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.

Glad to hear that. There’s some valley floor locations in the lower mon valley, that have probably been in the single digits the past two winters. It’s been a rough stretch for snow totals down that way for awhile.

Hopefully one of the few times WAA can benefit us. Having the nose of the confluence east of the apps could produce a slight inverted trough. This feature has benefited us in the past.

Wow, McKnight Rd around Peebles and Babcock is like another world.

Cranberry special right now.

https://www.ncdc.noaa.gov/stormevents/eventdetails.jsp?id=206605 Sunday mornings forecast reminds me of this event. I remember being glad I flew out the day before, instead of that morning.

Yeah, noticed on the higher elevation cams, a solid coating on the grass.

Flash freezing conditions could be an issue, along with the potential squalls.

Guidance seems to all agree on decent energy swinging through Wednesday night into Thursday. The setup looks similar to other frontal type snow bands we’ve seen. Could be a quick 1-2” in the heavier bands.

Congrats to you folks with the LES. It’s been awhile.

The latest 850's look ok, so with a marginal air mass, a rain/snow mix might be the best we do. Although, these flat progressive systems sometimes favor our region. Will definitely be a close call. Nice to finally have a more winter like pattern, instead of early fall.

This steady evening precip was handled well by the guidance. Impressive stacked LP.

No doubt.

This setup reminds me of 2/10/10. Decent moisture and energy on the wrap around. Unfortunately, temps are too warm for most of us.

Yep, first dusting of the season.

Euro is now showing the solution the GFS and CMC had last week. lol

Regardless of what happens later this week, hopefully the source regions north of the border, can start building a permanent snowpack. Last season a few decent setups had insufficient cold air to draw from. The way our winters have been lately, we can’t afford the waste any potential storms.

Felt more like August 30th last night.
