Hurricane Ida is making a run at Category 5 status in the remaining few hours before landfall along the southeastern Louisiana coastline. The latest observations of Ida include a well-defined eye, max sustained winds at 150 mph after rapid intensification of this system in the past 24 hours, and a northwest movement towards the Louisiana coastline. After landfall later today, Hurricane Ida will remain quite strong as it moves inland and it will gradually turn to the north in the nighttime hours and then take a turn to the northeast by mid-week. The post-landfall track will bring significant rainfall to the Tennessee Valley and then to the Mid-Atlantic region/Northeast US in the Wednesday/Thursday time period.

The Atlantic Basin remains active today with three systems on the tropical scene, but the one just to the south of western Cuba is of most concern at this time. There are strong signs that this system now officially known as “Tropical Storm Ida” will undergo rapid intensification this weekend once it gets past Cuba and out over the open warm waters of the Gulf of Mexico. The expected rapid intensification is likely to result in a “major” hurricane classification (i.e., category 3 or higher) of Ida before it makes landfall likely in the northern Gulf coastal region late Sunday or Sunday night. After landfall, the remnants of Ida will turn north initially and then to the northeast and tropical storm conditions could exist all the way into the Tennessee Valley. This post-landfall track would bring significant rainfall to the Tennessee Valley early next week – the last thing they need after recent flooding rains – and perhaps to the Mid-Atlantic region around mid-week.

The Atlantic Basin tropical scene remains quite active as we end the work week with two systems out over the open waters of the ocean and a third system over the northwestern part of the Caribbean Sea. It is this third system now over the Caribbean that is of most concern as it presents a big threat of a powerful hurricane by later Sunday for the northern Gulf coastal region. This tropical storm ("Ida") is likely to undergo rapid intensification this weekend and could attain “major” hurricane status (i.e., category 3 or higher) before a potential landfall late in the weekend. The remains of "Ida" are likely to turn to north just after landfall and could bring significant rainfall to the Tennessee Valley early next week - something that is certainly not needed.

The Atlantic Basin remains quite active today with three systems on the tropical scene, but the one over the west-central Caribbean Sea is of most concern at this time. There are strong signs that this system now officially known as “Tropical Depression 9” can reach hurricane status by the early part of the weekend over the Gulf of Mexico and then perhaps close in on the western/central Gulf coast by later Sunday or Monday. There is even the chance that TD 9 undergoes rapid intensification and strengthens enough in coming days to reach “major” hurricane status (i.e., category 3 or higher).

High pressure over the Tennessee Valley will lose control around here today as an upper-level trough drift northward from the Gulf of Mexico. As a result, the chances for PM showers and thunderstorms will increase today and this threat will continue on Friday and each day this weekend. High temperatures are likely to be near the 90 degree mark for the end of the week and during the upcoming weekend. On the tropical scene, there is an increasing threat for a hurricane - perhaps even a "major" - by the early part of next week in the Louisiana coastal region.

The Atlantic Basin remains quite active as we push towards the end of August with three systems on the tropical scene, but the one over the Caribbean Sea is of most concern at this time. There are strong signs that this system now officially known as “Invest 99L” can reach hurricane status in coming days and perhaps threaten the Texas and/or Louisiana coastline by the early part of next week.

High pressure over the Tennessee Valley will remain in control around here today resulting in plenty of sunshine to go along with quite hot and humid conditions. This system will weaken tomorrow and high pressure over the western Atlantic Ocean will take over generating more of a southerly flow of air and additional low-level moisture in the region. As a result, there may be more in the way of cloudiness on Thursday and this should knock a few degrees off the temperatures and increase the chances for showers and storms. High temperatures are likely to be near the 90 degree mark for the end of the week and upcoming weekend. On the tropical scene, there are signs for a possible hurricane in the Texas/Louisiana coastal region by Monday or so...something to closely monitor next few days.

The remainder of the week looks to be quite hot in the northern part of Alabama with high temperatures well up in the 90’s for the next few days. As far as rain is concerned, conditions should generally be rain-free for another day, but the threat of showers and storms will increase for the second half of the week.

The week ahead looks to be quite hot in the Tennessee Valley with high temperatures at or slightly above the 90 degree mark on a daily basis. As far as rain is concerned, conditions should generally be rain-free for the first half, but more unsettled in the second half of the week with a daily shot at showers and storms.

A trough of low pressure will build aloft over the eastern states during the next couple of days and it’ll stay quite active in the Tennessee Valley with more showers and thunderstorms. In addition, some of the storms that form can reach strong-to-severe levels with possible damaging wind gusts on the table. Meanwhile, Tropical Storm “Henri” will take a turn to the north this weekend and could end up near Long Island or New England by the time Sunday night or Monday rolls around.
