  1. The big blue circles that appear quickly are absolutely ducting effects in general.  But the bird signal tends to be buried in that noise because they aren't usually flying all that high off the ground and also because they roost at night and take off in the morning when the inversions are most pronounced.  The reflectivity levels they produce are often pretty low because even though they are solid with a decent cross-section there aren't all that many of them (usually) in a volume of air compared to say droplets in moderate rain.  Close to the radar where the measured volume sizes are smaller they'll be brighter.  Also, the correlation coefficient is lower compared to rain based on the random orientation of their wings and asymmetric shape.  

    Anyway I've met those guys and a few times I did get the sense that they were mistaking radar artifacts for birds but that would be the data in which you'd be looking for birds.

    The afternoon turned out surprisingly nice.  It’s always crazy to ski when it’s that mild and humid.  Snowpack crying for its mama.

    This outta help, ha.

    Yeah, it's over.  Good luck making it to Sunday.  Groomers can do magic but I had two locals tell me today was their last day.

    We’ve hit 75F for a max so far.

    Finally gotten in on the fun.

    Awesome day up your way, fair amount of fog shifting around run to run but super chill with a good bunch of peeps.  Hayride skiers right might have been my fave

    I love how Anthony can’t post anything inside of d10 for winter hope….and now we’re nearly into May.  When was the last time NYC had snow that late?   I remember a 2-4” event in April 1956.

    5/9/2020 had snow in Central Park, which is nuts

  5. Was full on spring the last 24 hours,  birds chirping, crocus and hellebores popping along with the dews, an altogether different smell out there.  Was nice.  

    Anyway sun's gone.  We cloudy

    Yeah, Quabbin still really low. Not sure why folks are poo pooing the MOD drought status. 

    It is low indeed.  Also, as of Saturday, was still completely ice covered, at least on the west fork.  I was surprised.

  7. Hard pass on a 16+hr drive to chase linear mode low topped thunderstorms with fast moving embedded tornadoes.  If you even see one you're probably too close. 

    But take the drive out if it and of course ;)
