    6Z Euro (and ensembles) is drier again.  This is a trend that it keeps getting drier and drier.  NWS and local mets leaning heavily on this model given its record.  

    Hard to bet against Euro/Ukie, but the ECMWF does not have a good record the last few events...

  2. 3am Disco:

    && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... Cold front to slip south through the FA Wednesday, while upper energy shifts to our east. It appears that most of the precip will be shifting towards the south and east during the day. Cooler temps to also filter in behind the front. Slow moving front to remain to our south Thursday while another upper disturbance moves east across the region ahead of an upper trough digging into the region. A surface wave is progged to develop off the SE coast and move NE. Cooler air will continue to work into our FA from the strong parent Canadian high to our NW while guidance continues to indicate precipitation for our FA Thursday into Thursday night. Some questions about precipitation type Thursday nt, mainly to our NE. Latest model ensemble means indicate some light snow accum across our E/NE FA. Local top down tool indicates a period of rain/snow mix Thu nt for the central and east FA. Confidence limited due to several key factors in our local perfect storm approach for significant winter weather not being met. Main issue is cold air not being in place before the onset of precip but rather is coming in as the precipitation/moisture is shifting out. Even if a period of light snow occurs, surface temps appear will be above freezing and warm soil temps would lead to melting and reduced impacts. Will leave in rain/snow mix for Thu nt but will not indicate snow accum at this time.

  3. I know in past years I've seen the occasional post mentioning increased data gathering around this point in a storm's timeline.  Has anyone heard if the NWS is planning to get additional information into the initialization of the models??  Or, would this system not impact a large enough area for that??
     
    Edit - It got really quiet in here... spooky!!!
    It is also almost 1am, people are tired, and several of us are trying to calm our hearts after Ryan Newman's wreck in the Daytona 500.

    Anyway, here are the 0z GFS suites7ed185254d3b31bd76b86156173fb06e.jpg

  4. Some things I’m seeing;

    Starting with the bad:
    - I don’t know how much of a northwest trend is really *possible* given that the shortwave is coming from the northwest. A shift north could mean a flatter system overall and could mean less precip.
    - Euro + UK combo saying no is a tough hand to bet against
    - Betting in a late blooming coastal always scares me, a lot can go wrong with transporting moisture that far away from the LP

    Now the good:
    - Hi-Res models haven’t gotten a good crack at this yet. They’re not just good for thermals, they’re *much* better at rendering topography. Can’t emphasis enough how much of a night and day difference a mountain range looks on the gfs compared to the nam 3k. I mention that because any shortwave gets stretched and contracted in the mountain west and that has implications downstream. Our shortwave is being held back in dang Utah may look a little different in the hi-res stuff
    - We have a wildcard I haven’t seen mentioned yet: this shortwave. It’s currently between Oregon and Hawaii and flies into Cali in 3 days like a bat out of hell. Pay attention to this storm; if it holds on some more of its integrity it could be a nice little boost to our Rockies shortwave 869791961b0ad346f051fe9b0a32eca6.jpg&key=4402403d10286b9c80cf5542bdf808e414621ff4c52eb471ffe5ceb6ec8999b7594eb6deb6c20c73899ba7adfc20bbd6.jpg&key=84cecf67866ecf617b22f4109856da4a27beae9cc7ac7492904b18f9d35a4ca2

    I’m pretty neutral on this storm, I’m not completely optimistic but it still has a lot of upside.

    You raise a good point, this storm hasn't even been sampled yet. Way too much time left to get on one model over another

  5. Man, I don't know grit.  I'd understand if we were on the fringes of the juice, but no model has significant precip near us that I can tell (maybe the nam long range).  You expecting a powerful NW trend here? Storms that are legitimate usually have some models in our court.  I'm just not seeing anything close. 
    NAM handles the extremely short range better than the globles (look at the last couple events), granted the hr84 NAM is to be taken only for verbatem from its track record but there is a lot of time to move pieces.
