High pressure is giving way to a strong low over Canada, which will result in light south winds over the mid-Atlantic tonight. That should trigger some migration over the region, but will be limited since high pressure still dominates to our south (and so the south winds are very localized). North winds will return on Sunday and Monday, limiting any migration into the early part of the week. It's a beautiful time to be in the field, and many of the local breeders are pairing up and defending territories... it's beginning to feel a lot like spring!

On the topic of migration, the mid-Atlantic forecast is now also on Twitter. I'll be posting migration 'alerts' whenever the radar is showing a big flight, or it looks like conditions will favor a fallout, so join me on Twitter here: http://twitter.com/BCMorgBFMA.

Good Birding,
