Upper Midwest waits for the next front, while the rest of the U.S. marches on

Upper Midwest waits for the next front, while the rest of the U.S. marches on

National overview

High-pressure-driven northwest winds across the Great Plains and Midwest kept migration activity low for the interior U.S. last night, but otherwise birds were on the move for the rest of the country.

Below are the radar loops from sunset last night through 5:00am (central time) this morning

Upper Midwest

Minnesota

Northerly flow across the region kept birds down for the most part last night.  A small amount of reverse migration was evident over both Minnesota radars during the night, but otherwise the night sky was very quiet. Expect little change in birding conditions today.

Wisconsin

Frames are every 1/2 hour. click on the thumbnail to view the full-sized animation.

The same goes for Wisconsin, where northerly flow dominated the region. Expect little to no change in bird density across the state with the exception of some localized movements into more optimal stopover habitat.

Iowa & Illinois

Frames are every 1/2 hour. click on the thumbnail to view the full-sized animation.

And lastly the same patterns hold for northern IA and IL. Northerly flow means little to no change in bird density across the region with the exception of some localized movements into more optimal stopover habitat.

As always, woodcreeper.com depends on you to report your sightings and be our ‘eyes on the ground’, so please come back and give us an idea of how we’re doing predicting birding conditions in your neck of the woods.

Good Birding,

One response to “Upper Midwest waits for the next front, while the rest of the U.S. marches on”

  1. Definitely more birds leaving than arriving in southern Dane county today. Less Goldfinches by far but a couple more Orioles, both Balt. and orchard. Otherwise no noticeable change in the yard.
    Drove to where the RN Phalarope was seen south of Stoughton. Saw it there Friday but not today. Checked many flooded fields and only counted about 5 Lesser YL and a couple Solitary Sandpipers. Still some diving ducks but not many. Checked some woods by Lake Kegonsa and was pretty much void of birds. Looked out of the wind and still nothing much. Virtually no gulls anywhere as well. Hopefully new birds Tues or Wednesday. Suppose to be warm south winds I here.
