Meteorologist Myles Henderson’s First Warning Forecast

Clearing skies and cooler… Expect plenty of sunshine this afternoon with highs in the mid to upper 70s, about 5 degrees below normal for this time of year. Temperatures will drop into the low 60s and upper 50s overnight with mainly clear skies.

The nice weather continues for Friday and the weekend. Expect plenty of sunshine tomorrow with highs returning to the mid and upper 70s. Temperatures will slip a few degrees for the weekend. Expect mostly sunny skies to partly cloudy skies with highs in the mid 70s Saturday and Sunday.

Hurricane Irma will approach south Florida this weekend then turn north. The timing and location of this turn will determine the impacts on Florida and much of the Southeast. We are expecting impacts from Irma on Tuesday. The level of rainfall, wind, and flooding we see will depend on the exact track.
