    Quite the wide swath of snow as well, although it is still showing a zone of heavier snow near and south of Philly.

    You know you want to look at it.

    From what I have read, the NWS chose the FV3 as the new GFS's (and GEFS) dynamical core in part because it uses less computer resources than other options.

    Just measured 0.4 inches. Just some flurries now and temperature down to 31.

    Snowing pretty good here and it did not take long for the grass, mulch and roofs to get a coating of snow. Temperature down to 32.

    I had to search some but hopefully this is what you are looking for… https://vlab.noaa.gov/documents/6609493/7858320/NBMv4.1NWPMatrix.pdf

    The NBM is time lagged. If there is a notable pattern change in the guidance and even a trend then the NBM will take time to catch up. Closer in time, the NBM incorporates the high resolution guidance which can lead to a noticeable change in the output. More info about the NBM is available here: https://vlab.noaa.gov/web/mdl/nbm

    Just extrapolate it.

    Yup something to watch as the NAM has an area of 850 mb FGEN strengthening some as it shifts east.

    I see what you did there.

    And you were not the only one at PHI to push the envelope on alerting. We have made some progress on that but still work to be done. Not an easy task either when staffing keeps changing.

    That inconsistency has been noticed by some NWS field offices, but I am not aware of where that stands. In my opinion if something like this NBM stuff is referenced in things like AFDs then some added info should be included to provide more context of that data. The deterministic NBM is bias corrected (60 days I believe) which results in a lag especially during pattern changes. Still not all that sure why a blend of models has a bias correction applied.

    The NBM is not the greatest guidance many times and I will leave it at that.

    You want to come back? We are still short staffed!

    Perhaps the ball would then be reported as a massive hailstone.

    Nothing like a Spring evening thunderstorm, oh wait it is 12/31. Happy New Year everyone!
  17. MGorse
    It is like a Spring night out there.
  18. MGorse
    Umm, sure.

    The 00z run will probably have nothing.

    Just lovely out there this morning. I hope everyone had a nice Christmas.
  21. MGorse
    Have not really seen any yet.
  22. MGorse
    Because you said 'heavy snow' and I was curious about the visibility. Just wanted to double check. Carry on...
  23. MGorse
    Observations under that enhanced area of snow on the radar are no where near 1/4 mile in snow. It is snowing pretty good under that here at the office, but visibility is above 1 mile.
  24. MGorse
    Hmmm, I am guessing not.
  25. MGorse
    Odd as I saw it updated earlier.
