That “cool front” we’ve been talking about for the last few days arrived this afternoon and will continue to bring in cooler and drier conditions, albeit slowly. Today’s afternoon high remained in the lower 90s, but was slightly higher than expected at 93 degrees. Tomorrow will cool a bit, into the upper 80s, but the real star of the show will be the considerably drier air. This front will continue to slowly push Southward, and the high pressure will filter further into the Southeast just as slowly then stall, allowing the cool weather to remain through the weekend and into next week. By Monday, the high will have shifted far enough East to cause Southerly “return flow” to set up, returning “normal” humidity and afternoon showers to South MS.
The tropics are only a few days away from having two less storms to worry about, but another disturbance is beginning to form in the Caribbean Sea. This disturbance currently has a 50% chance of developing into a depression within the next 5 days, and remains in a favorable environment for formation, though this will change drastically by the beginning of next week. Regardless of formation, this system will bring heavy rains to parts of Cuba, South Florida, and East Florida over the next few days. Both Tropical Storm Maria and Hurricane Lee are expected to weaken rapidly as this trough associated with our “cool” front pushes everything Northeast into the Atlantic.
