Category: Labor Day Weekend

Before we dive into our latest long range discussion, Laura continues to track north this morning through western Louisiana, and remains a category 2 as of the latest update (5a eastern time). Our thoughts and prayers are with all of those affected by Laura as they wake up this morning and begin to see the horror left behind from this beast of a storm.

Laura will take a hard “right” turn Friday and deliver gusty winds and heavy rain to the TN Valley and into the mid-Atlantic through the weekend.

We won’t deal with any impacts from Laura’s remnants up this far north, but we will increase coverage of shower and thunderstorm activity now through Saturday evening. This is thanks to a warm, sultry airmass in place along with an approaching cold front. As that boundary drives through the region Saturday evening, a much drier airmass will arrive for the 2nd half of the weekend.

Rainfall amounts between this afternoon through Saturday afternoon should top out between 0.50″ and 1″ for most, but there will be localized 1″ to 2″ totals in the heavier storms.

Friday will also pose a severe weather threat across the state, including the potential of damaging straight line winds as a couple “bowing” segments that move from the upper Midwest into the central Ohio Valley.

As we look ahead, we’re tracking 3 significant cold fronts between now and September 10th:

I. Aug. 29th

II. Sept. 3rd

III. Sept. 10th

Each of these cold fronts will be capable of producing strong storms and locally heavy rain, and behind each boundary, the air will grow cooler and cooler. While “transitional” warmth (relative to normal) is likely ahead of the boundaries, the first 1/3 of September should run cooler than normal across our region. Things also looks MUCH wetter than normal through the upcoming couple of weeks- a byproduct of the busy nature of the pattern.

Note how the latest JMA Weeklies are also similar handling the pattern (we’ll take the week-by-week snap shots into our video a bit later) over the upcoming 3-4 weeks:

One more item of note, the tropics aren’t done, unfortunately. There should be another hurricane threat in the medium to longer range period (early September) and early thoughts here include that threat centering more on the East Coast vs. the Gulf.
