More migration into the south (radar restored!)

National Overview

UPDATED: The radar feed went back up this morning but it looks like all the data prior to 2am was dropped, so here are the loops from 2am – 5am Central Time. The good news is that things should be back to normal for tomorrow’s post. You can still check out the loop from 3pm yesterday through today here on Paul Hurtado’s site.

OLD CONTENT: Talk about Murphy’s Law! The individual radar feeds from the NCAR site are down today so I have no radar to post for you.

Migration was heavy again across the south where Trans-Gulf migrants continue to pour in over the TX and LA coasts from Mexico. The stationary front across the midsection of the country still marks the boundary between heavy and light migration, with the lighter stuff obviously to the north of the front.

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

Since I will be publishing “as I go” each morning you may see some incomplete posts throughout the early morning hours. Don’t worry- it’s coming!

Little to no migration again last night for the Mid Atlantic with the front creating a strong barrier across the Delmarva Peninsula. I expect little change in birding conditions this morning as birds will only be moving locally under these conditions.

Migration was light to moderate throughout Iowa, Indiana and up to central Wisconsin with birds moving NW on SE winds. We’re still waiting for high pressure to come down and break up this frontal barrier, after which we’ll see a big push of Neotropical migrants into the system. Until then expect good shorebirding conditions at interior wet areas to continue and for the early season migrants (sparrows and vanguard warblers and vireos) to continue pushing farther north. Northern Wisconsin saw another big push into the region last night and should see some new birds this morning. Because of the lack of precipitation, I don’t expect any fallout conditions this morning and therefore birds should be distributed throughout the region today. Hey! Green Bay is back online! WOOHOO!

As always, 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.

One Response to More migration into the south (radar restored!)

  1. Sounds like birds are sneaking through with some awesome reports coming in right now:
    Highlights include
    CERULEAN WARBLER at Pheasant Branch Conservancy this AM
    A concentration of warblers at Governor’s Island, Dane Co., WI
    WILSON’S PHALAROPE and MARBLED GODWIT at Nine Springs E-Way Park (Dane Co.)
    VERMILLION FLYCATCHER at Lake Park in Milwaukee
    and a stunning male CINNAMON TEAL at Vernon Marsh just west of Milwaukee

    otherwise, though, migrant activity is spotty… but it goes to show that the weird stuff can and will show up on days of moderate to light traffic!
