Meteorologist Myles Henderson’s First Warning Forecast

A cooler, cloudy, and windy end to the work week… Temperatures will linger in the mid 70s all day, about 5 degrees below normal for this time of year and about 15 degrees cooler than yesterday. Expect mostly cloudy skies today with on and off showers. It will be windy today with NE winds at 10 to 20 with gusts to 25 mph.

Highs will warm to the low 80s on Saturday and mid 80s on Sunday. It will still be humid, so it will feel a few degrees warmer. We will see a mix of clouds this weekend with a few scattered showers/storms (20-30%).

We are keeping a close eye on a tropical system forming in the Bahamas. What will soon become TD Nine or TS Humberto will move closer to Florida this weekend and could move up the East Coast next week.

Tropical Update

Tropical disturbance moving slowly over the central Bahamas. The system is barely moving, but is expected to resume a slow motion toward the NW and NNW later today. On the forecast track, the system is anticipated to move across the central and northwestern Bahamas today, and along or near the east coast of Florida Saturday and Saturday night.

Maximum sustained winds are near 30 mph with higher gusts. The disturbance is forecast to become a tropical depression or a tropical storm later today or Saturday.

A tropical wave located midway between the Cabo Verde Islands and the Lesser Antilles is producing a large but disorganized area of cloudiness and showers. Conditions are expected to become more conducive for development in a couple days, and a tropical depression could form early next week while the system moves westward across the tropical Atlantic.

* Formation chance through 48 hours: Low (10%)

* Formation chance through 5 days: Medium (50%)

Another tropical wave is located a few hundred miles SSE of the Cabo Verde Islands. Slow development of this system is possible during the next several days while the it moves west across the tropical Atlantic.

* Formation chance through 48 hours: Low (near 0%)

* Formation chance through 5 days: Low (20%)
