seems precip is moving in sooner than expected?

very spotty and very light....I know NBC10 down here mentioned spotty precip running out ahead of the main stuff this evening and some model runs spitting out minimal qpf for a few hours before the "real" stuff gets in later so not sure this really is unexpected.

[famartin]

Yes, this definitely isn't unexpected.

^{Steady Light Snow ground getting white}

^{Temp 32.3}

[chubbs]

Very light snow - tiny flakes - 35

[Parsley]

Light snow just started. 35 degrees.

[Quakertown needs snow]

had some flurries

[phlwx]

went from ~ 41 on the Main Line to 37 in Rofo. Light drizzle down in Berwyn...spits of light rain/snow mixed when I got home.

[ChescoWx]

Wxsim with 18z data down to around 1" to 1.5" of total snow by tomorrow AM

Currently Light Snow 32.0

[RowanBrandon]

That radar posted above looks horrible.

[noctilucent]

Criteria for the advisory counties is 2". North of there its 4", IIRC.

Thank you. Thankyavurrymuch, Ray.

Here in Warrington, PA, 37.2, overcast with a light west wind.

Radar shows activity over us, but nothing falling from the sky.

Definitely not staying up for this one!

Radar looks pretty.....diffuse.

I do not think any criteria will be changed, however myself and some others at the office have been working on splitting Montgomery, Bucks and Chester counties into additional zones. This will especially help during winter weather with the upper/western parts of these counties typically getting frozen/freezing precipitation longer than farther to the east. I am waiting for a status update on this project, but hopefully it will be ready to go before next winter.

This will be a good thing. I've been hoping for this for a while since the climate in Quakertown is vastly different than Bristol.

Definitely, and lots of work has been put into this including factoring in elevation and climo.

Agreed 100%. Great idea proposed.

Will Mt. Trappe be the dividing point between NW and SE Montco or its own zone?

Somehow I remembered 4", but thanks for correcting me.

very cool idea, thanks mike

The office has been made aware though of the reports coming from that specific location (basically use with caution).

LOL.

Cool. Took us a bit over a year from proposal to finish (technically we still need to implement so not done just yet) but that's mainly because I dragged my feet learning ArcGIS.

Radar looks horribly dry......off and on light snow here in north Wilmington which is encouraging but lack of moisture I think is going to be the issue.

watch the stuff coming out by dc that should organize...the main strip tease isnt suppose to happen til after midnight towards morning,

[phlwx]

It used to be until a few years ago...I think around the same time they tweaked the ice storm warning stuff up in the LV (perhaps even before then).

[ChescoWx]

Thanks Mike!

[ChescoWx]

Much bigger flakes starting to come down now....any small change is duly noted in this winter

Temp 31.9

[iceman56]

Props to idea of splitting the counties! Conditions vary widely across Chester Co.

Snizzle all evening. Can see where snow will accum pretty quickly here in the valley as there is still a lot of snowcover

and ground is still frozen. A white dusting from these evening's attempts. 32.7 here, temp slowly dropping all evening.
