(probably thrown all over, well past me in the southern Great Lakes, but still super exciting)

Awesome to see this huge fall bird migrations on radar - def. one of the biggest liftoffs of the year here #birding #wxbirding

Check out our new Polar Vortex Blog! Though parts of the US have been very cold and snowy, experts do not think there's much evidence that the polar vortex is the main driver of our winter weather so far this year. www.climate.gov/news-feature...

Final set of additions to PolarWx for the time being - two AI emulator models (ECMWF's AIFS, and the GFS-based GraphCast) are now plotting in real time:

This is the kind of weather shenanigans (with reforming lows etc.) that make for really exciting weather-focused birding in the GL's! I'm so excited to see what's out there over the next few days..... #soexcited #birding #wxbirding

Super interested to see what sort of vagrants turn up in the Great Lakes over the next 2-3 weeks....... Weather support is in overdrive #birding

Interesting to see what this hog of a low pressure system does for AK birding (and downstream effects on NA birding through Nov) --- 850mb winds shown

Climatology + MJO + Intense pre-season forecasts = 👀 👀 👀 for Mid-August onwards for a few weeks... Not to mention the increasing interest and knowledge in knowing when and where birders end up in the field...

To-be "Post-tropical" Beryl is going to do it's very best to displace some birds into the southern Great Lakes in the coming days... Jet stream boost activated! #birding #hurricanebirding

I just... can't explain how exciting these maps are to a bird watcher from SW Ontario... #birding

A long-ish op-ed style piece from me in Nature, in which I consider the question "how doomed are we?" tl;dr: it's an existential, philosophical, and personal question. It sometimes gets posed as if it were a scientific one, but it mostly isn't. www.nature.com/articles/d41...

I am waiting with bated breath... Will there be Ivory Gulls in northern Newfoundland over the coming days? Will anyone notice if there are? #birding #IVGU
