[cobirds] Migration Weather Advisory: Sunday May 3rd

COBirders,

I urge readers to respect state and local restrictions on non-critical travel... this weather advisory is meant to inform you about what might be interesting birding areas for the next couple days.  If you live close to these areas, feel free to bird hard from the comfort of your local patch.

Sunday Morning: birds should be leaving the eastern Front Range tonight into tomorrow morning on southerly winds, which means you should see some turnover of birds (might not be good for Hudsonian Godwits [read my other post]).  But there could be more coming in with the changeover, so keep your eyes peeled.  The south winds are originating from the Arkansas River area of Colorado, so expect some slight pushes northward of birds, but maybe not far-flung migrants.

Sunday afternoon/evening into Monday morning: looks particularly good for bringing in some birds to the Denver area as well as along the I-76 corridor up to NE CO (with some room for variation of that exact convergence area).  There are even other areas to the south along the Arkansas River that seem to be funneling birds into the evening hours.  This could mean good things for Monday morning.

Ask questions if you have any.  I was in a hurry to get this out, so ask for clarification if needed.
