nightknights Posted January 18, 2015 Share Posted January 18, 2015 Two quick thoughts on the ice: 1. Even as some areas had readings near or just above freezing, ice resulted. This was probably because the ground temperature was < 32°, as surface temperatures are measured at 2 meters above the ground. 2. The coverage of ice is a big coup for the HRRR model and that model was growing more aggressive with the ice as it moved closer to the event. Two images from earlier runs of that model: don't know I watched the news last night and all they kept saying it was going to be very icy from 3AM on Link to comment Share on other sites More sharing options...
CoastalWx Posted January 18, 2015 Share Posted January 18, 2015 The hi-res models even yesterday hinted at ice. We were talking about ZR at LGA and EWR yesterday. Link to comment Share on other sites More sharing options...
rgwp96 Posted January 18, 2015 Share Posted January 18, 2015 I knew it was going to be ugly when I was 17 at 5 am . Up to 33 but still Icy out especially sidewalks Link to comment Share on other sites More sharing options...
WintersGrasp Posted January 18, 2015 Share Posted January 18, 2015 What a mess outside here. It's going to take some time for the rain to wash this away and gradually warm the ground. The lighter freezing rain/drizzle is the worst, because it has less of a chance of melting on contact Link to comment Share on other sites More sharing options...

WintersGrasp Posted January 18, 2015 Share Posted January 18, 2015 Predicting freezing rain or drizzle is a very challenging. The NWS originally had an advisory for NYC out and dropped it when temperatures were above freezing.. I tend to think that the NWS does a great job for the most part. However, with temps barely above freezing, wouldn't the threat still be there, being that freezing rain freezes on contact with a cold ground. Therefore, hovering just above freezing with the approaching precip would still be a risk (and would maybe err on the safe side) Link to comment Share on other sites More sharing options...

doncat Posted January 18, 2015 Share Posted January 18, 2015 They weren't above freezing verbatim.Yeah when they dropped the advisory here at 4 am , the temp was still 21 degrees and it was 27 when it started to rain. Link to comment Share on other sites More sharing options...

Therefore, hovering just above freezing with the approaching precip would still be a risk (and would maybe err on the safe side) I was thinking the same thing. If the ground surface is below freezing what difference does it make what the air temperature is. In this case many areas had a mist or drizzle to start which wouldn't warm the surface very quickly.

IsentropicLift Posted January 18, 2015 Share Posted January 18, 2015 Getting some flooding issues at this way. Combo of heavy rain and frozen ground = maximum run off. Link to comment Share on other sites More sharing options...
weathermedic Posted January 18, 2015 Share Posted January 18, 2015 NWS just put out a flood warning for the city and nassau through 6pm. Most of those areas received around one inch of rain already.
