Models struggle with ratios in these set ups.  I’ve seen many times over the years where Mt Holly picks up on this fact.  Vey low moisture can pile up when the conditions are perfect.

Trust the professionals 

Hoping for 4”.  Wouldn’t be at all surprised to only see 2-3”, but feeling good for some reason.  Meh

wow really.. I deal with middle schoolers all day. I don't need it here. Thought this was a weather CHAT. 

It’s currently 32 at my house with a DP of 18.  Ho read up on wet bulbing in storms like this one.  You might learn something

Again, post less, read more.

Thanks

But we aren't going to be that frigid. I could see 12:1 ratios but most of us are seeing lighter returns until you get to the Philly area. 

Ah, so you know more than professional meteorologists.  Got it.  Thanks.

Sounds a bit excessive...

19F

Not based on the mesos, which should be used at this point for small features such as inverted troughs

How rare is it to have super cells with large imbedded tornadoes forming off the cost of the Carolinas and making landfall in mid January.  Serious question.

Flip back to mainly snow here in Hatfield pretty crazy and unexpected

Keep an eye out for this slug of moisture heading NE.  I have a feeling that will flip you and ABE back to mix.  Curious to see if I am right.

No, I think I’m gonna be wrong

Didn't expect the flip back to snow here. Really coming down. Roads are the worst they've been all day. Pleasant surprise!

I am in Lansadale.  Surprised to see a lot of flakes still mixed in.  CC seems to be moving SE a tad near here.

Not sure how accurate Accuweather's future radar is but the rain/snow line is holding at least until 5:20 PM.  Appears to be heavy rates at this time also.  Hopeful to stay snow during this timeframe.

It’s not accurate.  Way off.  Use CC

If you’ve changed over don’t expect to flip back later.  The problem is warm 850s.  They won’t drop again until the low is NE of us.

And the mix has started just as the CC showed it .  Still mostly snow though 

Just about 2” now and heavy snow.

Can someone post a link to the radar that shows the mix line?

It Radar Scope.  The correlation coefficient radar

Mix line actually dropped a bit south for the time being by me so we still have moderate snow

Still coming down but mix line at doorstep.

My Upper Darby sis said she has had sleet for the past 1/2 now.   For Haz...

Yeah should have said mix line.  Rain just beyond that transition line

CC radar accurate for r/s line

So, looks like PHL will keep the record going and doesn't look to be touched in the foreseeable future.

That output looks reasonable, with perhaps a quicker drop off at the fall line especially due to ocean temps.
