Migration Weather Advisory: Thursday May 7th

[Bryan Guarente]

The floodgates are open... but unfortunately, they are open all the way up to Alberta/Saskatchewan over the next 6 hours and open to North Dakota over the next 12 hours.  So we should see some serious turnover of birds.  

Now (6pm May 6th)

6 hours out (midnight May 7th):

12 hours out (6am May 7th):

https://earth.nullschool.net/#2020/05/07/1200Z/wind/isobaric/850hPa/orthographic=-104.23,36.96,1966/loc=-105.077,40.187

Note that the winds are from the south and going straight over us into more northern states.  This is good for getting birds north, but maybe not as good for concentrating birds into our area.  If there are new rare birds, expect them to be spread out across the Front Range, not concentrated like they had been today (May 6th) and yesterday (May 5th).  

So the best thing to do on May 7th would be to stay home and hope for the best in your local patch because birds have a chance of being anywhere.  

NOTE: My emails don't mean that you should go chasing things and disobeying your counties/municipality's stay-at-homes orders.  

Best of luck tomorrow.  I hope you get some new birds in your patch.  Let me know about your data points by reporting to eBird or to COBIrds.
