Severe Weather Update...1:20 AM

We are still watching things closely for the possibility of severe weather this morning...A few individual cells have developed across parts of central Mississippi.

SPC has a Tornado Watch up for most of southeast Louisiana, and this will likely be extended into south Mississippi soon...

The dewpoint at Meridian's Key Field has risen to 48, which is still low, but the increase does show that the warm, moist air to our south is moving into the area.

We still believe there are two threats of severe weather, and the first threat is going to unfold over the next several hours. The main threat will be south of I-20, and will come in the form of large hail.

The low dewpoint values lead me to believe that these storms will be elevated in nature (that occurs when the thunderstorm is rooted on top of a relatively cool, stable layer of air near the Earth's surface). Elevated thunderstorms are usually producers of hail, and only rarely spawn tornadoes. However, in southern parts of our area, the moisture field is increasing quickly, and we could see some tornadoes...The best threat of that will again be south of I-20, close to US 84.

Another threat could unfold later today, as the cold core low swings overhead...And, the latest computer model guidance still suggests that we will see some VERY cold air later this week.

We'll be watching closely today...
