    It seems a couple MI ASOS sites near the IN border are reporting all snow, FWIW...

    I stopped short of making the leap, but my suspicion is that the HRRR's algos are confusing rimed snowflakes and/or aggregates (with the convective elements) for sleet.
  3. Powerball
    Not sure what to think of the HRRR. It keeps showing a swath of heavy accumulating sleet, which the profiles aren't really supportive of that.

    Kind of chuckled at this from IWX... FXUS63 KIWX 030956 AFDIWX Area Forecast Discussion National Weather Service Northern Indiana 456 AM EST Fri Mar 3 2023 A couple caveats do exist with this storm system and there seems to be a higher than normal bust potential due to the continued existence of uncertainty in the guidance. In areas with snowfall, the snow will be the very wet variety with snow ratios of about 6:1 to 10:1, so this makes the removal of snow much harder to shovel. Also, due to the wet nature of the snowfall there will be much more compaction with this snow which can lead to misleading snow measurements as once the snow falls and a measurement is taken, the actual depth will be less than actual snow amounts that have fallen. So keep this in mind. Another issue is that with this forecast we have taken evaporational cooling into account to allow for snowfall and this will not remain constant through the event which will introduce the potential for rainfall mixing in at times once the lower levels moisten up later this afternoon. So as I said earlier that this is was a very difficult forecast. So I guess what I am saying is be gentle with us if this system does not exactly go according to plan.

    Also, FWIW, the 06z RGEM did finally come in a bit stronger/warmer/NW.
  6. Powerball
    It seems it's just the RAP and UKMET (lol) that are on the stronger/warmer/NW end amongst the models now.
  7. Powerball
    Track-wise, it looks to be the same as the 00z run... The only real difference is the surface low's several MBs weaker as it moves through MO/KY/IN.
  8. Powerball
    Yep, it's been trending for a while. Although not severe, did just see another weaker line of t'storms move through a half hour ago with a decent pop of wind. Had power go in & out again.
  9. Powerball
    06z NAM and HRRR both came a bit SE, so there's that... EDIT: Also, the EURO and UKMET do seem to keep the ULL a bit deeper and closed off longer, which seems to result in a slightly healthier trowal (and is also why areas to the NW saw a bump in QPF and slightly warmer air impacts the Detroit area). But it just goes to show how extremely sensitive this setup is with the marginal thermals.

    I said nice downpour, not long. Radar does show a decent-looking line of heavy showers approaching. So maybe not a complete shut out from rain, lol...
  11. Powerball
    Although the severe weather potential is dwindling, it still seems you have a decent shot at a nice downpour.

    I think @michsnowfreak would be ok with that...
  13. Powerball
    For the interest of the Detroit folks, 00z GFS did shift back SE a bit (and it's a of a run)...
  14. Powerball
    Wow! Surprised to see DTX go with a WSW and 6-10" (mostly) area-wide...
  15. Powerball
    The NAM being so far NW won't be right, but it appears the RGEM, UKMET and other Hi-Res models from this morning are also going to be wrong with being so far SE.
  16. Powerball
    Oh...
  17. Powerball
    Aside from that stuff in SE Dallas, pretty good clearing has moved in.
  18. Powerball
    The cells along I-35 in Southern Dallas County are really trying hard to organize. There's a subtle eastward shift to them though...

    Some activity is starting to percolate along the Johnson/Ellis County border...

    Also January 1999.

    Eh, those cells still look to be struggling on radar right now.

    No changes with the latest SPC Day 1 outlook...
