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.

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.
