Hattiesburg is among the many, many cities nation wide that is experiencing cold that they are wholly unaccustomed to. Particularly in the southern United States, record cold on top of a huge winter storm is working to exasperate the situation. Lets see if there is any hope for improvement for these next couple days.

At 653PM, CT, Hattiesburg was reporting cloud skies and a temperature of 23 degrees. The deep, strong, broad trough across the country is still holding firm to it’s place over the Plains. Another round of snow and ice is currently falling over the Red River Valley, getting ready to shift into a more moisture rich environment to the east.
The wet weather will arrive in Mississippi towards afternoon tomorrow. The freezing line right now looks to slice just to the north of town, while enough warm air is expected to be drawn north to keep Hattiesburg in the rain overnight Wednesday into Thursday morning, though an ice storm is anticipated across the rest of Mississippi. The wavelength of the jet trough will contract after the storm has pushed to the east, and cold air will be able to dig south, leading to a chilly end of the week in Hattiesburg, but with the promise of some warmth soon after.

I’m not so sure about the threat for thunder. The system has a lot of juice, but I’m not sure there is enough instability in the region. Still, there is going to be a healthy dousing of rain, perhaps over a half inch. If that all freezes on contact to the north, it could be a scary situation from Jackson north towards Memphis and Tupelo. This is a big time system. Here is the next round of wet weather on satellite over the Red River Valley.
