PHL Jan 17-19 Snow/Ice/Rain Storm Obs

25.4 here at 1030 with heavy sleet/freezing rain mix (would say about 80% sleet). Roads are a mess. I sit at about 600' with 1000+ foot ridges to my east and west which is seem to be keeping the cold air locked with only a very light NNE wind. Wonder if we will break 32 here today?

I have a question guys. I'm sending this over from the NYC obs thread where we've noticed Wildwood's (KWWD) temperature reach 61 degrees so far this morning. Since no observing location in its proximity is nearly as high, thinking this is erroneous. A glance at the nearby buoys offshore doesn't show temps above the mid 40's over the water, adding to making this suspect. Furthermore, if recorded as official, it would go down as a record high for the site (previously 57 in 2006). I'm not familiar with the site, but it is purportedly from an airport in Cape May. What is the track of its accuracy this winter? Can one verify this location or is it unreliable? THanks.

The station is in Erma, about 6 miles inland. There are a lot of instrumentation errors there and the station goes offline a lot. I would rely on the buoys and ACY.

Same here. Temp has fluxed up and down between 24-27 with variations in precip intensity. Had 2" snow/sleet this morning. Wonder how much snow it was prior to the change to sleet. Probably 2.5 is my guess. Regardless the ice is building up steadily on all surfaces. We probably will not reach freezing, at least not until the precip tapers off in a few hours.

Just on the other side of the hill in Jefferson, Im up to 32.5 with rain

Looks like the ridge just to our east is keeping the cold air locked in as Jefferson (other side of ridge) is above freezing. Fully agree that looks like we stay below freezing until the precip begins to taper off. I think your estimate of about 2.5" of snow before the sleet is a good one. Ice is building up here as well. Temp continues to creep up, 26.5 now.

Thank you for the reply and information. I'll relay this over to the other thread where it had become a topic in the discussion.

:lol: That station is now reporting 68 degrees

92 - great pix - as an RU grad, curious what buildings those were.

32.5F in Rahway now - went above freezing in the last hour or so; 33.1F back home in Metuchen (my wife said it went above freezing around 10 am). With the precip mostly over, looks like we not only won't lose our snowpack, it grew with the 1.5" or so of frozen concoction we got. Yes! I assume with temps above freezing from now through most of tomorrow, the snow/ice will melt from the pavement, but not much from the ground, so whatever we have left will be serious cement once we enter the deep freeze (doesn't look like we'll be above freezing for 5+ days) and hopefully we'll add even more to the snowpack on Friday and later. Nice winter so far...

Wildwood isn't an official climate site. Wunderground just likes to pretend that it is.

92 - great pix - as an RU grad, curious what buildings those were.

32.5F in Rahway now - went above freezing in the last hour or so; 33.1F back home in Metuchen (my wife said it went above freezing around 10 am). With the precip mostly over, looks like we not only won't lose our snowpack, it grew with the 1.5" or so of frozen concoction we got. Yes! I assume with temps above freezing from now through most of tomorrow, the snow/ice will melt from the pavement, but not much from the ground, so whatever we have left will be serious cement once we enter the deep freeze (doesn't look like we'll be above freezing for 5+ days) and hopefully we'll add even more to the snowpack on Friday and later. Nice winter so far...

I'm guessing Nicholas Residence Hall.

Looks like the CRAS had the right idea with an inverted trof-like feature setting up over SE PA. Another inch or so late tonight to top off our ice? Then substantial snow Friday? Wow, what a winter!

I wonder how much of this is actually snow. The precip is advancing with the 850 line, and I actually think a lot of this is mixed if not light rain, at least in SE PA where the surface is also above freezing.
