High Pressure Takes Over

National Overview

Below is a snapshot of the national map with radar and weather fronts. Use this map to get an overall feel of migration and how weather affects nocturnal migration. High pressure sets up along the Eastern Seaboard, expect quiet calm weather for a few days peeps.

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

Key West and Miami radar were relatively quiet for most of the night with the exception of some birds crossing the Straits and some birds flying away from Miami radar. A small group of birds did however fly in from the Bahamas, this is best viewed on the Miami velocity radar but besides that it was quiet. Tampa radar picked up birds departing early in the evening, heading SE–>NW over the Gulf. Towards the end of the radar loop a new batch of birds seem to have made to the bay area and could have dropped out over this region. Look out for new arrivals around Tampa area today.

Miami and Key West can expect more of the same to be lingering around with the addition of a few new birds coming in. We expect mostly the Caribbean flavor, American Redstarts, Black-throated Blue Warbler, Common Yellowthroat, Palm and Prairie Warbler and Northern Parula among other Caribbean based migrants. Coastal locations should be best today, but with the arrival of the easterly component in the winds we want to say that inland migrant traps may be better today than they have been all week. Most birds are moving SE–>NW in the region.

Future forecast: Weather forecast models are somewhat mixed, but developing low pressure across the Great Plains will set up a “sling-shot” of sorts, shooting birds right over FL with the help of SE winds. This will enhance our chances of seeing higher temps and diurnal heating sparking off a few showers into the middle of the week. Late next week we may see a late season front that will up our chances of rain and birds! We are not sure about the timing of the approaching cold front into the state but keep your eyes out for the arrival of this front by late next week. Late season fronts are awesome for the state as we mostly get skipped during spring migration. This is especially true for S. Florida; birds are able to fly farther with a tailwind so we need weather to bring them down for us. Keep sending in your reports; we appreciate those of you who have taken the time to write to us this spring 🙂

As always Badbirdz depends on its readers to help us understand the magic of bird migration. We ask our readers to take a minute to email us at, post a comment on the site or share what you are seeing on our Facebook page. As a whole the Florida birding community is large and enthusiastic about bird migration, lets join together this year to make Badbirdz an integral part of every birders toolbox. Together we can track and monitor birds and learn more about this phenomenon called MIGRATION!

Nature is Awesome,
