The USA Mesonet is a network of 26 weather stations in southern Alabama, SE Mississippi,& NW Florida.
The same conditions that have been producing fog along the Gulf Coast can also cause some other weather-related mischief. An atmospheric inversion can cause radar beams to bend back down to the ground, showing 'rain' that is actually just trees and buildings. This phenomenon is known as 'ducting', seen in the animation over Cape San Blas, FL.

Merry Christmas morning! We hope Rudolph is equipped with fog lights and maybe a little radar to fly down here last night! Have a wonderful day however you choose to celebrate and drive safely if your merriment has to travel!

We hope everyone is enjoying some much needed sunshine- we know our stations appreciate getting to recharge! Despite the rain, we did meet a couple legends in the weather world last week- including Jim Cantore and NWS Director Ken Graham!
We hope everyone had the perfect Thanksgiving break, and for our students- this is the week you've been waiting for- the final week of classes! We're kicking off the week with a timelapse of the cold front from last week as it approached our USA Campus Station!

Have your mornings been a bit foggy this week? Ours too. Why? Radiation inversions. Calm, clear nights can allow the ground to cool, resulting in warmer air higher up. This traps the cold air below- seen in temp/RH data at 2ft, 2m, 5m, and 10m above ground!

You may have noticed it was a bit chilly in the south the last couple nights. It got down just below freezing for most of our area- but our Castleberry station hit 20.99°F early yesterday morning!
