Brian: Tropical moisture returns today, scattered showers and storms later...

Good morning! Tropical moisture that has been trapped across the Bahamas and Hispanolia for the past several days is finally working back into southwest Florida. In fact, this morning you can already see the effect: more showers and storms moving toward the east coast and Keys as the day dawns. Clouds will increase this afternoon with showers and storms developing first inland and then moving to the coast as we wind down the day near sunset. Tomorrow should be even cloudier/wetter as the tropical moisture sits right overhead. Bottom line: the first couple of days of fall will be much wetter than the last 7-10 days of summer!
 
Today's forecast:

Naples  Increasing Clouds  Scattered PM Storms; High 91
Bonita Springs Increasing Clouds  Scattered PM Storms; High 92
Fort Myers Increasing Clouds  Scattered PM Storms; High 92
Cape Coral Increasing Clouds  Scattered PM Storms; High 91
Port Charlotte Increasing Clouds  Scattered PM Storms; High 91
Hendry Co. Mostly Cloudy  Mainly PM Storms; High 89
Glades Co. Mostly Cloudy  Mainly PM Storms; High 89
DeSoto Co. Increasing Clouds  Scattered PM Storms; High 90
 
By the weekend, the deepest tropical moisture should start to lift back into the Gulf of Mexico and get pulled north toward an oncoming upper level trough in the eastern United States. This may lead to a few slightly (and only slightly) drier days by Sunday and lasting into early next week. By Wednesday, we'll need to pay close attention to the northwest Caribbean as Invest 95L (soon to be Tropical Depression 15/Matthew, it seems) drifts around near Central America and the Yucatan. All signs point to, at the least, a lot of tropical moisture nearby by the middle to end of next week.
