As the rain begins we’ll start seeing some cooler conditions immediately, but much colder weather is on the way and we may see a few moments of some wintry weather before the weekend. The cold front itself will pass through tonight by 10 PM, but thanks to some slow moving upper level features this rain will linger for nearly the rest of the work week. Instability will be low each day so thunderstorm activity will be isolated, but we’ll see scattered showers all day Wednesday, Thursday, and into the early morning hours of Friday. It’s this latter time frame that gets the most interesting as the 540 decameter line, also known as the rain/snow line, moves into South Mississippi before sunrise. If any showers linger long enough into the morning we could see sleet, freezing rain, or even a light snow flurry or two before the drier air moves in. As the weekend rolls around, evening lows will remain in the low-to-mid 30s while afternoons linger in the 50s with sunny skies. It will be cold enough for a light freeze, so be sure to take extra precautions to protect your outdoor plants, pets, and pipes.
