Migration weather: 5/4

[Bryan Guarente]

After today’s north to northwest winds, we started coming back around to southerlies that connect us once again to Mexico (Veracruz area), but this time with less precipitation impeding the pathway from further south. 

From nightfall:

Through to sun-up tomorrow morning:

The pattern looks good for migrants to show up from Pueblo (coming from NM) to Cheyenne (coming more from Veracruz). Keep your eyes peeled for new birds to make their way to us and have most of the birds that are currently here stick around. 

Then there isn’t a good push of migrants possible until after the COBC. So that means find the birds that are around now, learn where they are hanging out, then take advantage of those birds in your big day plans. 

May 7th 6am (COBC day at sun-up)

Enjoy tomorrow if you can get out. Keep me posted with any data points whether you consider those data good or bad. All data is good data. 

Thanks.
