Brian: One last evening burst of storms with 92L?

Good evening! Over the last few hours, the thunderstorm activity has increased on the western side of INVEST 92L, the wave I've been tracking the last few days in the central Atlantic. This is likely the last noise to be created by a dying wave -- as high wind shear stands in its path just to the northwest. That said, you can see on the above satellite image the bright red colors showing up early this evening, indicating higher/colder cloud tops and some stronger thunderstorms.

Whether 92L kicks up one last fuss tonight or not, its fate is essentially sealed by the shear zone lying to the west. All of our forecast models keep this shear in place as the wave passes through these longitudes.. this will elongate the system and allow it to ultimately weaken. Now, that doesn't mean the tropical moisture goes away. In fact, over the next 3-5 days, what's left of this wave will head toward Puerto Rico and Hispanolia after crossing the Lesser Antilles; there is the potential for significant flooding on Hispanolia as the wave passes by.

Beyond that, all of our modeling continues to point toward some of the moisture approaching south Florida during the middle part of next week. In our 7-day forecast, this is reflected by some cooler temperatures and higher rain chances starting on Tuesday (perhaps delayed a day into Wednesday). Scott has more on your forecast tonight at 10 on 6 TV and I'll be along a little after 11 tonight with a final update this evening. See you then!
