Here's your Tampa area weather forecast for late Thursday into Friday morning, as well as conditions through the weekend.

  • Hot and muggy
  • Localized flooding
  • Drier air next week

Moisture returned right on cue, leading to numerous scattered showers and storms across the region. Keep in mind that because the ground is saturated from Irma it won’t take much to get localized flooding anytime a storm passes overhead.

With that in mind, river levels also will continue to run high, peaking between Saturday and Tuesday in many spots as all that water slowly works into the river system.

Scattered storms die down overnight with partly cloudy skies into early Friday morning.

Lows will be in the mid to upper 70s.

Friday will be similar, with another round of scattered showers and storms.

Humidity is running high, which will make for very hot conditions for those without power. High temperatures will top out around 90. The coverage of storms will be at about 50 percent.

The storms will die down slowly Friday night with partly cloudy skies otherwise. Lows will be in the mid to upper 70s.

This weekend will start with a similar forecast of scattered storms on Saturday and highs around 90.

The good news is drier air is on the way from Sunday onward. Not only will that feel better, but it will help with the river flooding and allow the saturated ground to dry out.

TROPICS

Tropical Storm Jose continues in the Atlantic and is no threat to land at this time.

A tropical wave located about 800 miles southwest of the Cabo Verde Islands is producing disorganized cloudiness and showers. Environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression will likely form early next week while it moves westward at around 15 mph across the tropical Atlantic.

Another tropical wave, located south of the Cabo Verde Islands, is producing a large area of shower and thunderstorm activity. This system has become much better organized since yesterday and could become a tropical depression during the next couple of days before upper-level winds become less conducive for development. The disturbance is forecast to move westward to west-northwestward at 10 to 15 mph across the far eastern tropical Atlantic for the next several days.
