South Florida is contending with a frontal hang-up. What's left of an old, weak frontal boundary remains draped over the region. Even though this weather feature is a weak one, it's creating enough lift and instability to develop sporadic storms. On Tuesday, by the way, much of Broward and Miami-Dade received impressive rain totals with concerns for flooding in low-lying spots. Plenty of moisture is still available for rain, including more downpours.
It appears as though we need to be patient with this pattern. Expect more messy conditions with times of rain and thunder during the middle of the week. Then, as the front finally fades (Thursday) we'll see high pressure strengthening. The high is originating far to our north and northeast. Since there will be a big difference in air pressure, we'll have stronger winds by the end of the work week.
In the tropics, Leslie and Michael are no longer tropical systems. Both moved northward in the Atlantic, weakened, and lost tropical characteristics. Then, just as we were saying "goodbye" Leslie and Michael, a new disturbance was born. Presently, we're simply tracking one tropical feature... located in the middle of the Atlantic Ocean. The new system is expected to become Tropical Storm Nadine (and it could be named very soon). As for it's future, it is probably going to turn northward toward the end of the week. If that happens, there will be no land concerns whatsoever. Stay tuned. We're currently at the heart of the 2012 hurricane season!
