Nice burst of light snow here with some stickage. First measurable snow of the season. Aaaaand we're off and running

We got some of that here too! Pleasant surprise, not a bad thing at all.

No stickage here that I noticed, just a white rain event.

Heavy dusting 

.30"

Starting to become interested in next Saturday. Models have a weak Miller B setup and some of them hit us with a moderate snow event.

Really tricky forecast for Tuesday across Berks, Lehigh, Northampton counties per usual. Expecting the R/S line to make it to the 78 corridor, but never know. How much snow falls in these areas will depend on how quickly/heavy the initial WAA snows come in and how quickly (or not) the warm nose aloft lifts north. Southern parts of these counties won't do as well as the northern parts. I'd expect sleet to mix in more than expected, but we'll have to see what the CAMs show the next few cycles. Regardless, small shifts will make a big difference in these counties and it'll probably be a nowcast to see where the R/S line is on CC radar.

2-5" is a good call, 2 being the low end and 5 the 75th percentile or so. Reasonable worst case scenario is probably 6 or 7 inches

I like to thank my grill cover for measuring today

Like small nw shift but still I take

[RedSky]

Yeah extrapolating the cutoff in Jersey map i saw looked great but now that I see the run it took that jog back over Berks about a 40 mile shift from 0z

 

[ChescoWx]

All of the models have started to reduce snow totals by at least an inch from the last run....

[ChescoWx]

All that said the ensemble run held serve or even increased amounts a bit.....so you say there is a chance??

I went 1-3” on my page with the higher end of that range likely north of route 22. My concern remains the WAA push being stronger than modeled which often happens with events like this. Not as strong as the NAM, which is way overdoing it, but it wouldn’t shock me at all to see just 2-3 hours of snow. I think the R/S line makes it to around Blue Mountain or slightly north of there in the end.

I’m not liking that, the Jackpot zone this early usually craps the bed, by tomorrow it’ll be quick shot snow then rain. Seen it all to often.

35F holding on to the dusting

Frozen precip seems to stick to grill covers first. And with the black background is easy to see. May want to add this to the weenie handbook at a later date...

Cloudy/39F

bullseye is south mountain/macungie- my house --should be under a winter storm watch based on this model.  Mt Holly no time to be bashful.  The drivers in the LV have not seen snow in a long time. At least get them concerned about this storm event.  Its border line warning criteria I know but least get them prepared under a watch. Too many times in the last few years , an advisory level event has  turned into double digit snowfall events

[simbasad2]

Here are my thoughts regarding totals for the region for Tuesday. Keeping the heavier snow to the northwest with a sharp gradient as you approach I-95. I'm thinking I might shift this even farther northwest in future updates but we'll see
