Moderate snow with 3/8 mile visibility.  31/30

Went back to moderate snow during the past 30 minutes.  This transitioning back and forth between snow and mixed precip was well modeled and will make for an interesting evening as the heavier echoes move in from the south.  Storm total up to 2”.

Have gone over to a snow/sleet mix here.  30/29

Unfortunately it does not look like an initial heavy thumping is going to happen. Looks more like a gradual increase in intensity.

That is what has been happening out here.  It’s been snowing three hours here and there is all of 1” OTG.  Still waiting to see if we get the thump.

Steady light snow continues.  29/28. 1” new OTG

Borderline heavy snow in Hillsborough.  Can smell the rain. 

You are correct.  Based upon radar it looks like the rain/snow line is getting close to you.  It’s already close to Trenton.

Bright banding (sleet / big wet flakes) showing up on radar southwest and west of PHL.

Much of the Philadelphia area has already changed over to rain.  The snow/mix/rain line has already moved at least five miles north of the main line of the Pennsylvania Turnpike in the Philly suburbs.

Snow started here in Metuchen (we're at 34/30F) around 1:15 pm and we have a nice dusting now.  Looks like some heavier stuff coming and I haven't been in the loop as I was out for the last 5 hours, but is that sleet hitting the Philly area now?  

It looks like rain to the south of center city and snow to the north of there.

Precip is falling as rain in the suburbs to the SW of Philadelphia as that R/S line slowly works its way north.

 Overlooking the PPL CENTER downtown Allentown visibility is dropping quickly.  

 

I am down below a half mile here.

Snowing heavily in the Harrisburg area.  Roads are really bad in that area.

Visibility’s just to my west in the Allentown area look to be about a half mile.

Steady light snow- visibility 1 mile.  31/24

Snow flurries starting here.  31/24

They're ready for their 12-18"

Those were Henry’s thoughts.

Moderate snow in Reading, PA

Light snow into the Allentown area.

I am expecting 4-6” here with a transition starting at about 7PM.  30/24

Do we know what is actually hitting the ground vs virga? It still says doing nothing in Philly. 

I am looking at live traffic cameras on the Penndot site.  This is what is actually making it to the ground at the present time.

Snow is getting ready to move into the Reading, PA area.  It never ceases to amaze me how fast these WAA snows move in.  I was figuring a 1PM start here in the Lehigh Valley however at this rate I think it will start by noon.

Walt noted earlier that the intent was to use this thread for obs for the current storm.

Snow is reaching the ground from the I81/I78 split east of Harrisburg to areas just north and east of Lancaster, PA

Euro had this back at 12z.  It was further inland with its track but a big hit.

I will watch it especially the trailing vort .

Interesting evolution with this event as shown on the 12z NAM.  Front end thump Saturday afternoon into the evening for areas to the north and west and then most areas that had snow go to light rain/ice and sleet.  Most areas including the coast go back to snow later Sunday as the trailing vort max comes in.
