Soak up the sun while you can, as this week has hotter temperatures and fewer storms in store! The overall chance for rain will decrease this week, though afternoon sea breeze storms along the coast will still be possible. If you’re outside catching some rays, keep water handy, as a dangerous combination of heat and humidity will make it feel more like 100-105°F.
Ridging in the upper levels of the atmosphere is limiting storm development, allowing summer-like conditions to stick around throughout the week.
As the week goes on, forecast guidance shows the ridge beginning to break down, allowing rain chances to gradually increase heading into the weekend.
By Friday and Saturday, a nearby cold front will bring a better chance for showers and thunderstorms across northern Alabama and Mississippi. Farther south, sinking air associated with high pressure should keep most southern locations relatively dry, though an isolated shower or storm can’t be ruled out.
Early next week, things change as an upper-level trough makes its presence well known. Bringing with it the return of severe weather and the possibility of a mesoscale convective system (MCS), a large complex of thunderstorms.
Long range guidance shows a low-pressure system and cold front moving across the northern Gulf Coast states next week. While we are still about a week out and details remain fuzzy, there is still potential for stronger storms, so it remains something to monitor. In the meantime, enjoy the heat and sunshine!
