After the wettest day since Dorian, a ridge of high pressure will usher in fall weather for a few days, with the potential for the first 40° readings of the season Thursday and Friday mornings. Then, a slug of tropical moisture will bring in another solid rain chance late this weekend into next week.
We’ve just got one more sweltering Augtober day left before a backdoor cold front swings through the area, cooling us off for the weekend. This will come with a little bit of much-needed rain, too, but don’t expect a washout. After that, another frontal system will usher in a little bit more Fall weather.
Fall fans, the news isn’t great: Above-normal temperatures will continue for the foreseeable future as a strong ridge of high pressure remains firmly entrenched over the area. A weakening front nearby will help kick off a few showers and maybe a thunderstorm or two across the area. This would be good — it’s been twelve days since measurable rain at the airport — but not everyone is going to get relief. Rain-free conditions move back into the area for the weekend while temperatures in the upper 80s remain more in line with mid-August norms than late September.
By the time some of you read this, the autumnal equinox will likely have passed (3:09 am), ushering in astronomical Fall. (It’s been meteorological fall since September 1.) Don’t tell that to Ma Nature, though. High pressure aloft is re-establishing itself, ushering us back into what is effectively a very summer-like pattern for the upcoming week.
We have a really nice weekend of weather coming up as high pressure remains firmly in control across the area. Cool starts will give way to comfortably warm afternoons with highs in the mid-80s and low humidity. Rain chances are nil, and we should see plentiful sunshine throughout the weekend.
So let’s start with the good stuff: Model agreement has continued to improve regarding Tropical Storm Jerry’s future path, and that path is toward recurvature way from the US East Coast this weekend. (Bermuda, which just took a pretty good whooping from Humberto, will want to watch Jerry with wary eyes.) But, for Charleston, Jerry increasingly looks like a storm about nothing. It is forecast to become a hurricane later today, but will encounter hostile upper-air conditions that will limit its further development, according to the Hurricane Center. This should preclude the stronger solutions and a more southerly track as seen in a few of the global guidance members that we discussed yesterday.
Tropical Depression Ten strengthened overnight, having reached Tropical Storm status and the threshold to receive a name. The name most of us thought this system would get was Imelda, but a tropical depression formed quickly near the Gulf Coast yesterday and was named within an hour’s time. Imelda is already inland, so we are now watching Tropical Storm Jerry as it churns in the Atlantic, 960 miles east of the Leeward Islands (and a lot farther than that from Charleston!)
A warm start to the work week will give way to a taste of fall to close it out. (I mean, my goodness, 82° and fair skies on Thursday? Pinch me!) Plus, no worries about the tropics for the foreseeable future, either. Here’s a look at the week ahead…
The National Hurricane Center has started advisories on Potential Tropical Cyclone Nine. This is a wave that has not yet become a tropical cyclone, but the probability of it becoming one is high enough for NHC to issue Tropical Storm Warnings for the Abaco Islands and Grand Bahama — exactly where they are not needed. If named, PTC 9 would be Humberto.
