At hr 48 the 0c 850 line is south of LI and the surface freezing line cuts through western suffolk. It's snow unless there's a warm nose that I csnt see for Nassau into NYC

Hour 48 on LI 850`s  -2   surface  NS  upper 20`s    SS  32 - 33     .04 LIQUID   if you`re 925`s are ok , thats snow 

Hour 54- its rain  mid 30`s and plus 4 at 850

Hr 54 is rain for the coast

 

Considering how abomindable the Euro is with BL temps my guess is we can subtract 2-3 degrees at least from what it shows....holds on my theory only ERN LI maybe goes to pure liquid

If you take into account that low level cold is likely being under modeled a long with upper level warmth, the equation equals an extended period of icing.

This thread its so confusing. I don't know why.

Ya know. I a was just saying the same thing. Even the products put out by the NWS are confusing me.  As for tomorrow's event. I can't decipher when it starts, how it starts, etc...Last page there was a text product from a NWSFO and I couldn't decipher it..

Anyway, I agree. I know this isn't a forecast site, per se, but I am still confused re: how this is all setting up for tomorrows event.

Brief sleet/ZR to start before quickly flipping to rain in Philly proper. NW burbs hang on an hour or two longer. South Jersey is mostly rain.

 

Please...what does ZR refer to?  And at what approximate time is the "brief sleet/ZR" to start in Philly?  

 

Like others, I've been trying to make sense of this thread but the time designations are still confusing me.  (If someone mentions 0Z they mean 7 pm east coast time, yes?  And when someone refers to "hr 48 or hr 54," what is the hour from which one counts?

 

Thanks much.

He's saying brief sleet/freezing rain to rain for PHL but the maps I just saw said much different as the 0C line struggles to make it past 95.
