As a huge trough shifts east and takes the cold weather of the past couple of days with it, southerly wind is returning to the area and will set the atmosphere up for our next cold front, which arrives Monday evening. Warm air ahead of it, moisture from the Gulf of Mexico, and lifting provided by the front will bring showers and thunderstorms to the area on Monday afternoon and evening. However, due to the recent cool spell, it does not appear that the atmosphere will have enough time to "recover" to fuel severe thunderstorms. In general, we expect periods of heavy rain and some thunder and lightning from late afternoon through the evening hours, and gusty south wind throughout the day Monday ahead of the front.

While details are still sketchy, the timing of this system could be similar to Monday's and the potential for severe weather looks higher than Monday. The dynamics of the system look stronger as the low pressure center dragging the cold front through will be much closer to the Mid-South than Monday. The Storm Prediction Center has been monitoring this system for a few days and highlights a portion of the Lower Mississippi River Valley, south of the metro, for the possibility of a squall line of storms preceded by supercells with possible tornadoes. We'll be sure to provide updated information as the date draws closer.

However, with the possibility of strong storms later in the week, please be paying attention to the severe weather safety tips we provide throughout this Severe Weather Awareness Week. A tornado drill is scheduled for Wednesday and we'll host a Google+ Hangout training session on Tuesday night on #mSpotter - our Twitter-based severe weather spotting program that we partner with the NWS on. Be sure to join us! All the details on the week's activities, including some awesome giveaways, are posted on our Severe Weather Awareness Week page, as well as posts on Facebook, Twitter, and Google+.
We also want to provide you the opportunity to have the technology available to keep you safe during severe weather. So, to honor awareness week, we have discounted our StormWatch+ service by 33%! Check it out in the MWN mobile apps for iPhone and Android devices (links below).
