  1. Tomorrow looks pretty meh. Maybe a little flip to snow as the dry air really begins advecting in. Mesos aren’t wild about it. Looks like a half inch at best east of the high terrain, but I wouldn’t be surprised if even that fails. Western upslope areas may get a sneaky few?

    So for the dedicated snow weenies here, what is your take on when ASOS reports UP?  I always thought it was IP, but can it be a mix of R/S/ or R/IP or S/R/IP?  Never ZR?

    I’ve found it’s usually sleet. I suppose it technically can report it in other scenarios, but I feel like you usually just see it defer to the alternate ptype when there’s a mix…or the dom type in a RS scenario.

    I’ve just seen it report S with a jump up in vis too many times when there’s ptype goes from straight S to an obvious SIP mix.

    Unfortunately ASOS is pretty bad with L/ZL detection.

    I wonder if the extreme shallowness of this airmass back door) should have been a flag that the NAM was overstating the impact too much. The airmasses with backdoors are generally shallow but this one seems even more so than your usual. There is no secret that this time of year (and 99% of the time) you toss the NAM temperatures. But when you have situations like CAD or BDCF potential...well the NAM deserves alot of weight. But the low-level airmass in place is quite unseasonably warm and I guess even for early March, we have enough solar heating and mixing to either halt the BDCF or weaken it. 

    If you follow MSLP evolution on SPC mesoanalysis you can clearly see either the boundary weakening or even kind of retreating. Despite the stronger heating though, we're clearly having trouble mixing so there is definitely something going on within the BL. 

    It’s there. It came through. It’s not warming up much despite the sunshine NoP. It’s just functioning more like a weak seabreeze with slightly higher density sfc air than a classic stratus NE shat fest.

    Not complaining

  4. For areas with bare ground and sun I wonder how difficult it would be to mix out this shallow POS. If you look at the first few vis images of the day you wouldn’t even know one was through…it looks like a pure warm sector. The shit stratus is way offshore in the GOM and the cloudiness with the main boundary is up around the international border. 

  5. Well the backdoor came through a couple of hours ago but skies are SCT/BKN. We’re still wedged and hanging around 40° too while other areas mixed out to near 50° before falling again.

    Looks like it may end up being warm SoP.

    9-13" on the level...17" drift...dont ask me how, but I lost 2" Hi of 76.6* recorded on the station located right where I measured.

    DP is 44.1

    Most resilient pack I can ever recall.

    Still 12-14” here

    High of 68° today but back down to 49° with the clouds.  Because even on the sunniest days, somehow the clouds find the upper Valley.
    The DP‘s are going to take their toll so I’m guessing I’ll be down too 50% snow pack by Thursday. Probably about 90% right now.

    It'll be interesting to see how strong the wedge holds tomorrow night. I think I'm SOL here. The cold front will be my warm front.
