  1. Cudos to those that got the hammer.  Those that got the sink,  models seem to be giving you a second chance SE bump with wave 2.  Looks like there will even be a moisture starved wave 3 that could toss those of us in the orphanage an inch here and there maybe Sunday.  NYD is forecast to be the warmest at KIND since 2000, ROCK!  There's plenty of consistency over the next 10 days from the models... for absolutely nothing.  WTF do they know! lol :tomato:

    Yea models did depict dry slot well. It just seems like this moved out so fast. Maybe I'm wrong. Cutious to see what model did best so we know which one to watch closer for 2nd storm. 

    The models recently are like watching NeckCar at Talladega.  Whomever is leading, the next lap they're liable to be 20th the following lap.  But there's gonna be 2 or 3 big ones they catch, just a matter of where east of the Mississippi it happens :lmao:

    The convective nature of the snow in Iowa was very impressive. Tons of lightning strikes showing up near and north of the transition line. You can see gravity waves on reflectivity. Pretty awesome.

    Saw that on Scope also (seeing as how it's the only decent radar left!).  Meso was showing some decent 6-6.5 lapse rates moving up ahead of the mixing line.  Don't think I've ever seen gravity wave depictions on radar in a winter storm.

  4. Nice LR discussion from Ryan at KIND.....

    .LONG TERM /Wednesday Night through Sunday/...
    Issued at 241 PM EST Sun Dec 27 2020
    
    The second part of the storm system set to impact the region the
    second half of the week remains the primary focus for the extended
    and unfortunately at this stage of the game...is offering more
    questions than answers on specific impacts for central Indiana on
    New Years Eve and New Years Day.
    
    A strong ridge across the eastern half of the country will be slowly
    but steadily flattened by a strong upper low that will pinwheel out
    of northern Mexico and across Texas Wednesday night and Thursday
    before lifting north into the Great Lakes by late Friday. There has
    been a noted westward shift in the model suite over the last 24 to
    36 hours with respect to the upper low track due to more energy
    aloft carving out the massive trough over the central portion of the
    country and a strengthening of the upper ridge off the Florida
    coast. The upper low takes on a negative tilt which pulls it further
    west as well.
    
    That being said...the model suite is all over the place with its
    handling of the secondary surface wave set to develop along the
    frontal boundary and lift northeast towards the Ohio Valley by late
    Thursday. While there has been a westward shift at the surface as
    well...the main operational models with the exception of the GGEM
    are further west than the ensemble means. It should be noted that a
    surface wave track due north or slightly east of north off the
    Louisiana coast is a bit of a climatologically unfavorable track for
    a surface wave. Just another point to toss into the jumble of
    thoughts this afternoon. A general blend at this point is preferred
    until better model agreement can develop.
    
    So...what can we take away at this point 4-5 days out? Confidence is
    high in a higher impact storm moving through the Ohio Valley and
    central Indiana for New Years Eve and New Years Day. But that is
    about all that can be said right now. The lack of model agreement
    and fluidity of the entire suite lends no confidence into the
    details of the forecast and impacts...namely precip type duration
    and intensity. The storm will have access to a rich plume of
    moisture from the Gulf of Mexico which will ensure modest precip
    amounts from Wednesday night into Friday. Expect rain to continue as
    the precip type to start Wednesday night with the potential for some
    wintry mischief on the northern flank of the precip shield late
    Wednesday night into Thursday morning as low level thermals become
    marginal. There is likely to be a lull in precip coverage on
    Thursday before moisture returns with the approach of the second
    surface low late Thursday into Friday. Storm track will become
    critical at this point in determining precip type but the potential
    for at least some snow and/or ice accums is a possibility that needs
    to be considered. A track that ends up east would bring a greater
    risk for either snow or ice but even should the track of the low
    remain further west...an easterly flow in the low levels Thursday
    night into Friday morning as the low approaches could present some
    problems over the forecast area with an increased potential for an
    icy mess in the form of freezing rain and/or sleet.
    
    Expect at least another 36-48 hours before we can gain more clarity
    on the details with this storm system and the likely impacts locally
    here in central Indiana. The primary area of upper energy will come
    onshore over California on Monday with better sampling of the
    feature coming thereafter. At this point...prepare for a higher
    impact winter storm over the Ohio Valley from the second half of
    Wednesday into New Years Day with locally heavy rainfall...a wintry
    mix or perhaps some accumulations of snow and/or ice all within the
    range of possibilities. Dry and chilly weather will follow the
    departure of this system for next weekend.
    
  5. Who am I foolin lol.  Might not see snow till next month.  Hazard of my climo.  That FG band was pretty broken up when it was S/SW of Indy.  Filled in nicely as it moved NNE.  If we can keep some decent UL forcing going for the next 6 hours or so could end up being the first healthy grass topper around here.  Definitely some good snow globe stuff out right now.  IWX might wake up to a surprise  :thumbsup:

  6. We'll see how this pans out but certainly looking like a decent Omega block out west.  That should keep any moisture running up the eastern seaboard for the next 10 days at least keeping us zzz to a flurry or drizzle.  That's fine with me.  I'm ready to set the rest of Dec. up for the last week.  I think 2020 owes the entire sub a 3-6 blanket the last week of the year. :thumbsup:

  7. HiRes models not looking good for NW OH NE IN.  They were showing an enhanced defo band lasting through the night but a weaker surface low seems to be escaping faster.  At least y'all got "measurable" snow.  My LES tickler has about petered out. :P  Got an inch once temps dropped this evening.  Combination of grapul and micro flakes due to warm 850's from the NW?? lol

  8. For what it's worth the 00Z HRRR came in stronger and a bit more west longer with the surface low than most other guidance.  Gave OH,  Eastern IN, KY and TN  a lot more love at 10:1 than previous runs.  It still looks skittish due to warm boundary temps but it was a pretty decent tick up.  Keeps the surface low under 990 and parks it in western PA and NY through the end of the run.  Could be even better news for the N OH folks in the snow belt.  Btw, it also hammers parts of the NC/TN mountains with spots up to 20 inches.
