High Intensity Weather Over Florida

This is the radar from 5:00pm last night to 10:30am this morning..

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

Wow that pre-frontal trough looks nasty on radar. Hope everyone is OK and that the rains and winds did not damage any property across northern Florida as the squall line moved through the area.

As the cold front continues to push southeast into Central FL the air mass ahead of the front is very unstable. This will be the cause for developing thunderstorms and high winds. Thunderstorms are developing out over the Gulf and moving inland, these storms are capable of high winds, frequent lightning as well as the threat of large hail. As the cold front slowly moves SE we expect more development of storms especially as the temps climb. By midday the atmosphere will be prime for the development of severe thunderstorms. One good thing is that the approaching line of storms seems to be falling apart and losing strength. Again the afternoon will be a time for concern due to convection from afternoon heating which will make the upper atmosphere unstable. Keep an eye out for developing storms while out birding today.

Well migrations is slowing down and heading for the end. Every night we see less and less movement into the state. Last night we saw a small exodus of migrants from the Miami area and a moderate influx from the south. Birds could be seen crossing the Straits and meeting up with a westerly component to the winds which pushed migrants into south FL. As the first line of showers approached so did the birds; these signals look to have avoided the rain by flying east away from the rain. Birds were flying out over the Atlantic in search of favorable conditions and headed back to the mainland north of Miami. From Ft. Lauderdale to West Palm Beach looks to be our best guess as to where these birds dropped down. Check out your favorite migrant traps in this region for best chances of glimpsing a Connecticut Warbler 🙂 We expect most of these birds to be Caribbean based migrants such as Redstarts, N. Waterthrush, Black-throated Blue Warblers etc… Spring migration is coming to an end so take advantage of the last few pushes we will see in May. Blackpoll Warblers are also moving through the State and sometimes can be concentrated in large numbers when stormy days like today arise. Listen out for their buzzy call and Redstart like chips.

  1. Still seeing a few warblers, mainly F Redstarts, F BTB, and pairs of Yellowthroats, in my NE Broward yard over the last few days. They show up just before and after the storms and are feeding very actively. Also Nighthawks! Yesterday during the NAMC at Green Cay we only found Redstarts and Blackpolls, so they seem to still be around in low numbers.
