Meso discussion SUMMARY...Snow should overspread the region in the next few hours. With time, the snow should transition to sleet and even freezing rain before ending later this evening/overnight. DISCUSSION...An area of mixed winter precipitation continues across western and central Pennsylvania this evening. This precipitation area developed/is being maintained on the nose of strong low-level warm-air advection across a deep layer. Over the next few hours this warm-air advection and associated isentropic ascent will overspread eastern Pennsylvania and much of New Jersey. Surface temperatures in the upper-20Fs and low-30Fs, coupled with dewpoint temperatures in the upper-teens and low-20Fs, yield wet-bulb temperatures below 32F. Thermal profiles across the region will initially support all snow. However, as the warm-air advection warms the low-levels, the maximum temperature in the column should increase above 32F yielding sleet and potentially eventually freezing rain before precipitation ends

It helped that a stronger piece of energy came out of the sw

18z euro is mainly sleet and frz rain for the metro

I was more referring to how the radar looked not the placement of the rain/snow line
-
Your biggest issue is if the -pna is too deep out west. You need something to redevelop similar to tonight. But if that block is further north it will hold on to the primary longer
-
I think this looks pretty identical to the radar currently in Pa. Everything looks aimed towards the metro but what ptype is up to debate. I do like how strong and solid the returns looks currently
-
The block is to far north and the pv is not south of Hudson Bay. You need that with a -pna and se ridge

The trend today has been weaker with Tuesdays energy and putting all the energy into Thursday. It’s over for Tuesday outside central Va
