Heading back to W MA this morning after moving to TX for business reasons. Could be the most exciting wx I've seen all spring. With the nino we've had great lapse rates down there several times but hardly any shear. Now we'll see if the opposite can produce. Local pockets might be able to come up with a small amount of surface instability in the valley, kind of hope the line shows up a bit later than progged.
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.
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
The UMass X band has been performing great of late after some upgrades. Nice to have some high res looks at convection again, this far from Nexrad. You can see the shear tightening up just west of Noho. Doubt this amounted to anything but still cool.
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
