  1. Slicked over driveway and walkway in Cherry Hill. Light ZR, 27. Radar looks relatively juiced east of the Delaware so we may be in for a bit of a nasty evening this way.
  2. Big flakes battling steady rain here in western Cherry Hill (3 miles east of Ben Franklin bridge). 33.8
  3. Encouraged to see a pickup of snow here out my window an on the radar across much of Central and Southern NJ. Hoping it continues to fill/enhance.
  4. Yep, I am getting light snow right now too. Radar is anemic though so I'm surprised we're getting much of anything here.
  5. The 12z HRRR, while upping the amount of precip/snow in the PHL area, also looks to have a poor handle on the current precipitation in SNJ (brown regions indicate over-modeled precipitation).
  6. Another key to watch for this morning is low placement. One of these models is not like the other and happens to give PHL a lot less precipitation:
  7. So much disagreement, so little time! Time for the radar watching games especially for those of us in Philly, immediate burbs, and SNJ/DE. With the HRRR being so pessimistic for this area, I look to find any discrepancies in precipitation extent and then can decide if the rest of the run has a a clue or not. I am a little encouraged to see some more actual precipitation being picked up near DE. Interestingly, HRRR is lacking the heavier returns into NY/MA. Hard to make a call just from this but keep an eye on the trends.
  8. The HRRR is a bit lacking in the eastern extent of the precipitation: jmmweather.com/hrrr
  9. Sure. The image is just the reflectivity of the actual radar minus the simulated reflectivity from the HRRR model data valid at the same time. Basically this: Minus this: Equals this: Qualitatively, it shows the model (HRRR) is under-doing the precipitation where it's green. So this may have implications further into the forecast. It's more useful as we get closer to start time or for watching meso-banding.
  10. Obligatory shameless plug for my tool to help ease your radar hallucinations. www.jmmweather.com/hrrr Anyway, 25/10 here in Cherry Hill. Good luck to all!
  11. Sleet started about 15 minutes ago after almost 6" snow! Great few hours of winter!
  12. Just WOW. Closing in on 4". Not sure if I've ever seen these rates sustained like this. I keep thinking the changeover to sleet is imminent, but the CC shows the mix line tries moving north but gets beat back down again. I'm sure it'll be sleet soon though. 1216201629.mp4
  13. For what it's worth, the HRRR nailed the heavy snow this side of the Delaware river.
  14. Ridiculous snow right now. Added another inch in the last 30 minutes. Closing in on 2.5". The neighbor kids are loving it almost as much as I am. SNOW.mp4
  15. Overperforming here in Cherry Hill! Was on the roads 30 minutes ago and luckily it wasn't too bad. Lots of slush.
