Some Potentially Bad News...

Note: You can click the above image for a full-size version.

* This is the Infrared Satellite imagery this morning across the Deep South. You'll note the stripe of relative clearing from central LA, along I-20 through central MS, and into central AL. While the sun has not come up, this could potentially be very bad news. The sun could come out in our area today, which would lead to a strong increase in the amount of instability present in the atmosphere. The already high probability of severe weather would increase dramatically as a result.

* NOTE: The image above, as mentioned, is infrared. That means it shows the temperature of the clouds, and low clouds have a relatively warm temperature. The warmer temperature clouds, like low clouds, are generally more difficult to detect on the infrared suite of data. I peaked out my window, and I see these low clouds. So, there is not complete clearing in that band, a few low clouds remain. But, once the sun rises, these low clouds could be mixed out quickly, leading to sunshine.

* I also note the dewpoint at Meridian's Key Field is up to 63. Hattiesburg's dewpoint is at 66. The atmosphere is primed and ready to explode.

* Still expect thunderstorms to initiate to our west over the next few hours. These will rapidly become severe, and could also become tornadic. Best threat here still from 8am til 4pm. Scroll down for more info...
