A very unusual intense fall storm has been hitting the upper midwest the last couple days. This storm set an all-time record low atmospheric pressure reading for USA yesterday for a storm of non-tropical origin (i.e excluding hurricanes). The barometer dropped to a record low pressure reading of 28.20 inches or 955 mb in northern Minnesota. This is a giant storm spanning from Canada to the Gulf that gave us a few day period of pronounced south winds aloft. It does not surprise me that vagrants are appearing from the south...i.e CAVE SWALLOWS and now CATTLE EGRET. Who knows what else is out there?
Anyway, I am uncertain about what kind of wind patterns it takes to bring Old World species over to North America. I would imagine it would be a prolonged east wind that extends from Europe to North America. This rarely happens...especially at higher altitudes. Interesting thought though...

Is there a weird weather pattern going on across the Pond or to our south? I guess the strong southern winds could explain it. cheers, Matt -------------------------------------------------------------------- mail2web.com - Microsoft® Exchange solutions from a leading provider - http://link.mail2web.com/Business/Exchange -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES ARCHIVES: 1) http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html 2) http://birdingonthe.net/mailinglists/CAYU.html 3) http://www.surfbirds.com/birdingmail/Group/Cayugabirds Please submit your observations to eBird: http://ebird.org/content/ebird/ -- -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES ARCHIVES: 1) http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html 2) http://birdingonthe.net/mailinglists/CAYU.html 3) http://www.surfbirds.com/birdingmail/Group/Cayugabirds Please submit your observations to eBird: http://ebird.org/content/ebird/ --
