Location, location, location

"Location, location, location" is what the real estate folks always say... but YOUR LOCATION (at least this Labor Day weekend) could determine whether you are spending more time inside your home, or outside the house!
On Saturday, most coastal communities only had to tangle with a few nuisance showers, while many inland spots were hit hard by persistent storms. By the middle of the afternoon, there were flood advisories for much of central and southern Broward County, as well as central and southern Miami-Dade! Additionally, thunderstorms contained gusty winds and hail. There were also a couple waterspouts near the middle and lower Florida Keys.
As it turns out, we are still under a stubborn, broad spin of low pressure over the region. It's a low pressure area that's high in the sky (what we call an Upper Low) and it triggers a bunch of instability showers and storms.
In addition to the "upper low spin" there's also an impressive pool of moisture to our south... in the Caribbean Sea. The deep moisture is in combination with a Tropical Wave mainly south of Cuba. The bulk of that moisture is expected to remain to our south... due to expanding high pressure that's east of the Bahamas. As we continue through the Holiday weekend, the upper low is likely to finally lift-out, while moisture levels drop (slightly) for south Florida. Having said that, only a small amount of instability... like the daytime heat and sea breeze boundaries... can still lead to downpours, in spots. Overall, rain and storm chances should decrease during the remainder of the weekend. As for the isolated storms that MAY still form, they will favor locations that are "more inland".
Now that September has arrived, we're just days from what's known as the PEAK of the Hurricane Season. For the time being, we're simply watching 2 separate disturbances: in the central and eastern Atlantic Ocean. The one that's "more central" has a shot at impacting the islands of the Caribbean (into the new week). The good news? development and growth opportunities are very limited due to interfering winds, called wind shear. The shear should keep the disturbance as a Tropical Wave, but it's still possible that it could take a more southerly path and get stronger. We will need to monitor the wave... as some of the forecast models carry it toward our region by next Thursday or Friday. If that happens, of course, our local conditions will revert back to storminess and more unsettled stuff. Stay tuned.
