  1. There are some very potent snow squalls in the Harrisburg area right now. There are some very low visibility’s associated with these. On radar at least this activity is slowly translating to the east. If anyone reading this is going to be traveling west into PA and west of Allentown I 78 is closed due to accidents at Hamburg.
  2. There are actually some good bursts of snow in the Harrisburg area right now. The latest run of the HRRR is not too bullish on that area of snow translating to the east with much potency.
  3. It really has been booking off to the east as of late. Conversely the back edge of the snow is moving to the NE across VA at about 60 mph. This storm is a fast mover.
  4. Actually for the time being it does not appear that the changeover line is proceeding any further east (as seen on traffic cams). It still runs from about Jugtown Mtn along I78 to the area where 206 connects with I80.
  5. Steady snow / 34 degrees. Already sticking to non paved surfaces. This was a direct flip from rain to snow with barely any sleet. The HRRR had the changeover from yesterday at 8:00 AM today and was spot on.
  6. Heavy snow is coming down just west of Allentown. Visibility’s along I78 as shown on traffic cameras is under 1/2 mile with moderate to heavy snow.
  7. There have been comments made about the snow amounts being provided by the RGEM (RDPS). One of the Mets on the board- SnowGoose - provided an explanation this morning on this thread regarding this. It has to do with the Synoptics playing out with this storm and how the model handles it.
  8. The gradient will be sharp however it may not be quite that sharp. This may be related to how the algorithm used by the website uses the output provided by the model.
