Frontal Action Over Northern Florida

This is the radar from 5:00pm last night to 6:00am this morning.

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

A cold front moved into northern FL last night and is still over the panhandle region slowly moving to the east. Winds are variable but ahead of the front a south wind gave migrants a push if they departed Mexico. Behind the front N-NNE winds have developed and should slow birds progress as they fly for the coast. Upper level winds associated with the front are westerly and should push migrants towards FL rather than Alabama. Birders in the panhandle should be out looking for arrivals, remember these birds take more than one night to fly to North America when they are crossing the Gulf. Afternoon arrivals would be likely if migrants took to the skies out of Mexico. If migrants were aloft they would have met up with the effects of the front as well as a headwind, causing their progress to slow immensely. These conditions coupled with lots of rain can cause a “fallout”; we hope to hear from our North Florida birding buddies today.

Farther down the state Tampa and the Space Coast saw some action on radar. Birds were migrating over Central FL in hopes of making out of the state before the front hinders their northward migration. Jacksonville radar looked much the same, birds moving out of the state in a mad dash. We expect some newbies to be around in this region but as we wrote yesterday, precipitation is needed to make migrants really noticeable. When small amounts of migrants descend we have a harder time locating these birds as they disperse and become less detectable.

Miami radar look somewhat promising with signals coming in from the SW and from the east. We expect new arrivals on the ground with this sort of movement. Migrants may have chosen to put down early due to the stormy weather to the north. Inalnd locations look best but any migrant trap should yeild some new birds for you.

As always, Badbirdz depends on YOU to report your sightings and be our ‘eyes on the ground’, so please come back and give us an idea of what you are seeing in your neck of the woods. This will help us better understand the radar images and in return we can pass this knowledge onto you
