Rarities on the Wing

Rarities on the Wing

I took this screenshot late this morning via this always helpful and very cool wind map. They use surface wind data from the National Digital Forecast Database, updated hourly, to create this national flow of air. Even without it in motion you can see there is a huge trough in the east, with winds shooting down from the northwest until you get to about Chicago, at which point the bend brings them screaming out of the south and then the east higher into New England. All of this unsettled weather can easily push avian migrants out of their chosen path, bringing southern resident rarities up to...

Crazy Climate Maps

One benefit of the continual and seemingly never-ending cold and snowy winter (also known as spring now!) is that it provides us a tremendous opportunity to engage and educate people.

More thunderstorms and flooding

I would say “another day, another thunderstorm” but we get multiple events in a matter of hours lately. We’re well past water capacity in a number of areas in the Chautauqua-Allegheny region as flood advisories and flash flood warnings are already posted in places getting even more heavy rain now. Lightning is flashing intermittently as I type this. Stubborn and “stuck” patterns are becoming more and more common thanks to climate change and our jet stream. We need a trough in the west and a ridge in the east soon please. Be safe out there and remember…turn...
