SOUTH MISSISSIPPI (WLOX) - In July, we take any break from the heat we can get in south Mississippi. It looks like we might get that break Saturday evening with the arrival of a cold front. While rare for cold fronts to make it this far south in late July, it's not unheard of.
More rain and storms possible - some strong to severe
The front is expected to arrive in south MS by late Saturday evening. However, showers and thunderstorms will be possible well ahead of it. Perhaps as soon as noon. A couple of those storms may be severe with isolated strong damaging wind gusts possible.
Widespread severe weather is not expected as there may be a few limiting factors. One of those limiting factors is sunshine which is needed to destabilize the atmosphere and provide energy needed for strong storms. It is possible clouds may be present Saturday morning. This will help keep the atmosphere stable, meaning less energy for storms.
Another limiting factor is a lack of strong upper-level winds that could provide the dynamic forcing needed to sustain strong storms.
So will it be cooler?
Don't expect a significant cool-down, but it will feel a little more comfortable Sunday into Monday as dryer air will filter in. Temperatures will still be in the upper 80s to low 90s. Essentially, this front will take the "edge" off the heat, keeping heat index values in check.
