April 30th, 2015

Tonight's paltry migration
May is nearly upon us!

While this last night of April promises little in the way of migration, it appears that May will arrive with a bang. Tonight's decisively northerly winds are set to give way to weaker, leaning southerly-based winds tomorrow night. Along with this transition of winds, tonight's paucity of migration will undoubtedly give way to more migration tomorrow night. There remains potential for some spectacular movements, so keep your eyes on the wind and radar tomorrow evening.

Spectacular movements, provided the wind forecast stays true, are almost guaranteed for Saturday night. Put another way, this year's first heavy concentrations of migration are extremely likely on Saturday night, with a chance for them tomorrow (Friday) night as well. The southerly tailwinds forecast to facilitate this migration are also forecast to last at least until Monday, when high pressure is set to divvy up the state's winds. Exciting stuff, eh? At this point, it looks like we'll have notable movements on Friday, Saturday, and Sunday nights.

Cool! Curious what you'll find out there Saturday or Sunday mornings? Of course you are! Check this eBird page for Illinois bird bar charts, or check BirdCast's latest national migration forecast. BirdCast really does a spectacular job; their reports are what inspired these.

With that, I hope you have a great night and an even better time birding tomorrow!

Exciting winds forecast for Saturday night.
