    let me help. The trends are pretty much on track for a 24-36 hour period of snow showers/squalls wrapping around an occluding upper low. Model output on accumulations in situations like this are variable at best. If your looking for a solid 4" event this is not it. If your looking for periods of snowshowers with the potential for an inch or two over a long period of time you'll be pleasantly surprised I suspect. More importantly, it maybe signalling a colder and snowier pattern versus days on end of cloudy and seasonable temps. Personally, I like these type of set ups as a winter weather enthusiast (:weenie:). Perspective is key.

    Still doesn't change the fact that it has trended worse for us each run. Monday evening it was looking much nicer. Even yesterday morning. My concerns are the marginal (at best) temperatures and if we don't see steady snow, I could easily see a tenth or two falling and then melting so on and so forth. I have hopes the pattern gets better after this, but I'm not as excited as I had been even last week. 

    Cary's 15" at ORD call by March 1 is looking good.

    Here's LOT's take

     

    
    Thursday through Monday...
    
    A large upper trough will dig over the central CONUS on Thursday
    as an upper ridge amplifies over western North America. This upper
    trough will then develop into a closed upper low late Thursday
    over the Midwest, then gradually shift eastward across our area
    on Friday. Overall, this will result in a period of cool and
    active weather across the region late Thursday through Friday.
    
    Precipitation is expected to develop over the area Thursday
    afternoon. As it onsets, expect it to be in the form of rain, due
    to initially mild temperatures close to 40 Thursday afternoon.
    However, this light rain is expected to transition to light snow
    from west to east through Thursday evening. Some minor snow
    accumulations will be possible Thursday evening, but amounts look
    to remain under an inch.
    
    As we head into Friday the upper low is expected to shift
    overhead, and this essentially set up a vertically stacked
    surface and upper low over the area. Additional periods of snow
    can be expected over the area on Friday, and it looks to be more
    showery (convective) in nature. Low-level lapse rates should
    steepen considerably as a much cooler atmospheric column develops
    under the upper low overhead. As such, we could see some scattered
    instances of more vigorous snow shower activity on Friday, which
    in turn could support additional accumulations. This snow shower
    activity may persist into Friday night before the the entire
    weather system shifts to our east into Saturday.
    
    For the weekend and into early next week it looks like
    temperatures will be a bit colder then in recent days following
    the passage of the late week storm system. While our current
    blended forecast guidance suggests advertises a generally
    precipitation free period from this weekend onward, we will have
    to watch for some additional chances of snow later in the
    weekend. There is some support in the forecast guidance with
    another northwestern impulse tracking across the area sometime
    around Sunday. If trends continue to support this, future forecast
    updates will need to consider adding in a mention of light snow
    for the area later in the weekend as this potential system tracks
    across the area.

    Sounds really enthused.

    I never like to bust a forecast, but figure if the bust is for less clouds than forecast, that would be appreciated by most given how cloudy it's been lately. You're probably in the minority lol and you get your clouds back today and probably through tomorrow too.  

     

     

    I know Wednesday-Wednesday night looks mild ahead of the front, but I wouldn't lock in temps being able to rise that much yet. That kind of warmth aloft coming in will mean a sharp inversion locks in if there's existing cloud cover (which looks quite possible) and surface advection will be from over areas still with deeper snow cover. Wouldn't be surprised if forecast high temps bust low on Wednesday.

     

     

     

     

     

    Yes, I'm quite confident most everyone else appreciated the sun! lol

    Hope you're right about Wednesday. Concerned everything will get wiped out and then it will be cold and brown. The worst!

  4. I was really hoping to retain it prior to the colder pattern, but looks like whatever is left will likely melt almost completely by Thursday. If we don't get any snow with push of cold air after that, it will be worst case scenario - cold and brown. Euro gives some hope of at least a couple inches, we'll see. Still a long ways off. What a ridiculous dry spell, but that's been par for the course here. We've had very long periods of dry weather since June.

    Spot on, it's unfortunate to have the zzzzs that long but hopefully it ends up being worth the wait. Very good EPS and GEFS agreement in the western ridging retrograding off the west coast beyond January 1/15. The other noteworthy development in the past few full ens runs is amplified poleward ridging with the ridge axis up across the center of AK. 

     

     

    Given the continued Arctic and North Atlantic blocking, that strengthening -EPO signal ups the ante for very cold air to get involved in addition to the RNA (-PNA) due to the retrograding western ridge supporting a more active look. Prior to the -PNA (if the ens are on the right track) we could start to see more clippers materialize and the lake effect belts should take off.

     

    The good news is that the ensembles haven't backed off at all on a more favorable look for the subforum. The bad news is we still have this long boring stretch to get through.

     

     

     

     

     

     

     

    I'd love some clippers.

    Revisiting what I posted earlier today, no changes in overall thinking based off most recent ensemble runs. End of 12z EPS quite promising in showing a slightly -PNA developing as the western NOAM ridge retrogrades off the west coast, which the GEFS continues to point toward as well. We can only hope this look gets to within 10 days because I could see it offering multiple chances to more than localized portions of the sub given the -AO/-NAO favored to lock in.

    Prior to that, definitely a stagnant zzzz look. There's a chance some southern stream energy can break through later Sunday into Monday to bring a light snow threat for some areas. Ensembles showing low to medium chances of light measurable QPF during that time and the 12z GGEM did show a weak wave as well. Definitely not seeing anything supporting even widespread advisory type snows while we're in this blocky STJ dominated pattern.

    As long as I can retain much of my snow cover, I'll be okay until it snows again.
