Brian: Scattered storms this afternoon, highs in the low 90's...

Good morning! Scattered showers and storms are in today's forecast as the afternoon Gulf breeze kicks in (wind will be much lighter today than it was last week, allowing that Gulf breeze to kick in). Some heavier downpours are possible as precipitable water values (amount of moisture in a column of the atmosphere) are well over 2" across south Florida. Showers and storms may have an inland drift to them with time by late today as an upper level trough and surface front move closer -- this will allow the steering flow to turn more southerly and southwesterly by late in the day.
 
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 91
Cape Coral Increasing Clouds  Scattered PM Storms; High 91
Port Charlotte Increasing Clouds  Scattered PM Storms; High 91
Hendry Co. Increasing Clouds  Scattered PM Storms; High 92
Glades Co. Increasing Clouds  Scattered PM Storms; High 92
DeSoto Co. Increasing Clouds  Scattered PM Storms; High 91
 
Starting tomorrow, the forecast details become a bit more murky. We have low pressure developing in the northwest Caribbean near the Cayman Islands this morning. While this low is now not expected to get very strong (because of how widely spread all of the energy is -- rather than concentrated in one spot -- as well as some upper level wind shear in the southern Gulf), it will potentially be a very rainy system as it moves toward south Florida at mid-week. There are still some questions as to whether this tracks more to the east toward the east coast of Florida; if this happens, we'd end up with less rain here on our side of the state. More on this situation a bit later this morning.
 
Have a great Monday!
 
Brian
