Drier Times Ahead
Posted by Brent Cameron
The latest stretch of wet weather days goes back to Sunday. Since then, excessive rain showers and storms have been bombarding all of south Florida. Thunderstorms have not only been persistent, but capable of being real drenchers. Daily doses of heavy rain has also increased the threat for more street flooding. Those flooding concerns include all areas from the Keys to Lake Okeechobee! On Tuesday, some of the hardest hit spots were in both southern Miami-Dade and northeastern Broward counties. A general swath of 4-inch rain was reported between Homestead and Naranja, by the way!
Deep moisture has been lurking and that has been the main culprit. Additionally, a large spin of low pressure (in the upper atmosphere) has helped enhance more rainfall. Our "moisture maps" (called water vapor) clearly show a division between the tropical moisture and deep drying... east of the Bahamas. Considering the air flow, that means a large batch of dry air is on the way, here! The drying trend is likely to take over by Thursday and Friday. The result will be "little to no rain" at that time.
Along with the approach of drier air will be a substantial amount of African Dust. Sometimes called Saharan air, this boils down to being "dust particles" that are suspended above us. Most people will only notice a lot of haze, as the African Dust moves over south Florida. During the day, you'll see a milky looking sky (with hazy sunshine and a glow around the sun). Then, during dusk, sunsets are expected to be more colorful than usual... making for a beautiful sight. However, if you or a family member are sensitive to air that contains particles, it could be an extra concern and more difficult to breathe. You may find it necessary to stay indoors in the air conditioning. Stay tuned.
