During the past 24-36 hours, Hurricane “Delta” has undergone rapid intensification – the most extreme for an October tropical cyclone since “Wilma” in the super-charged year of 2005. Hurricane “Delta” is now pounding the northeastern part of the Yucatan Peninsula region of Mexico. After that, “Delta” may make a direct hit on the north-central Gulf coastal region (e.g., southwestern Louisiana) by late Friday or so and then take a turn to the north and east once inland with significant rainfall in the Deep South and Tennessee Valley – perhaps even bringing some late weekend rainfall all the way to the Mid-Atlantic region.

All systems are go for Hurricane “Delta” as it has undergone rapid intensification in the last 24 hours and will very likely reach at least category 4 “major” hurricane status over the next 12-24 hours. During the past 24 hours, Hurricane “Delta” has seen its maximum sustained winds increase by 70 mph – now at 110 mph – which represents the fastest October intensification of a tropical cyclone since “Wilma” of 2005. Hurricane “Delta” is headed towards the northeast part of the Yucatan Peninsula region of Mexico in coming days – very likely as a category 4+ storm. After that, “Delta” may make a direct impact on the north-central Gulf coastal region (e.g., southern Louisiana) by late Friday or so and then take a turn to the north and east once inland with significant rainfall in the Deep South and Tennessee Valley – perhaps even bringing some late weekend rainfall to the Mid-Atlantic region.

Hurricane “Delta” is now a category 2 storm over the Caribbean Sea and is likely to have a direct impact on the northern Gulf region (e.g., Louisiana) by late Friday or so after skirting the Yucatan Peninsula region of Mexico. This system will remain over the still very warm waters of the Caribbean Sea and then Gulf of Mexico for much of the time in coming days and may reach “major” hurricane status. Once it makes landfall in the northern Gulf, “Delta” remains are likely to push north and east over the upcoming weekend.

The month of October began with very pleasant conditions in northern Alabama and throughout the Tennessee Valley. The passage of another cold front served to bring us a shot of cool, dry air as we closed out the work week and it’ll stay quite comfortable right through the upcoming weekend. Sunshine is likely on both weekend days and highs will be close to 70 degrees on Saturday and 75 degrees on Sunday.

The month of September closed out with nice weather and the new month will begin with very pleasant conditions in northern Alabama. The passage of another cold front will serve to bring in a shot of cool, dry air as we close out the work week. In fact, it’ll turn cooler on Friday compared to today with highs confined to the mid 60’s in the Tennessee Valley. The comfortable weather pattern will continue through the weekend with sunshine likely on both days and highs within a few degrees of the 70 degree mark.

An upper-level low pushed a cold front through the region yesterday and it will result in comfortable conditions around here for the mid-week. There will be another cold frontal passage later in the week with a reinforcing shot of cool air for the Tennessee Valley. Meanwhile, the tropical scene in the Atlantic Basin remains quite quiet as September comes to an end.

A slow-moving cold front will produce rain in the Mid-Atlantic region from later today into early Wednesday and some of the rain will be heavy at times and embedded strong thunderstorms are possible. It’ll turn a little cooler at mid-week, but a second cold front will bring an even cooler air into the eastern states for the upcoming weekend. As the central and eastern states experience significant rainfall and an unfolding colder weather pattern, the western states will get hotter and stay dry and this will enhance the wildfire threat.

An upper-level low will dive southeast today towards the Ohio Valley and it should produce mainly cloudy skies around here today with the chance of afternoon showers. It’ll turn quite cool tonight following the passage of a cold frontal system and there will be another cold frontal passage later in the week with a reinforcing shot of cool air for the Tennessee Valley. Meanwhile, the tropical scene in the Atlantic Basin remains quite quiet as September comes to an end.

The Atlantic Basin has entered a relatively quiet period with respect to tropical activity and it may last for several days. However, there is little doubt that this is just temporary reprieve as sea surface temperatures remain quite warm across the Caribbean Sea, Gulf of Mexico, and the southwestern Atlantic. The upper air pattern across the nation will change next week to one that will feature an intense upper-level trough of low pressure over the central and eastern US and a strong high pressure ridge along the west coast. As a result, colder-than-normal conditions will dominate the central and eastern US by later next week and hot, dry weather is likely in the western states which will increase the chance of wildfires.

The combination of a frontal system pushing northward from our south, an upper-level jet streak, and some leftover moisture from “Beta” will increase chances today for showers and thunderstorms and some of the rain can be heavy at times. An upper-level trough will shift to our east on Friday, but the threat for showers and storms will continue for another day. It turns warmer this weekend across the Tennessee Valley, but a look at the longer-term suggests it could turn quite cool later next week in much of the central and eastern US.
