A tropical wave moving over the state of Florida will bring much-needed rain and a slight cool down to Tampa Bay through the weekend.

While the term “tropical wave” may send a slight shiver down your spine, it just means there will be some extra moisture in the air. The wave is not a tropical storm or a hurricane, and it is not being monitored by the National Hurricane Center, said Matt Anderson, a science operations officer with the National Weather Service’s Tampa Bay office.

“What kind of impact does that mean for us, in general, in the Tampa Bay area — it just means that we’ll be getting a lot of rain,” Anderson said.

Rain chances across Tampa Bay are elevated through the weekend. On Thursday, when rain chances are around 60% in Tampa, rain will likely begin in the afternoon and evening. Through the weekend, rain chances run as high as 80% across Tampa Bay.

Anderson said the highest chance for rain will be in the afternoons and evenings and will likely be run-of-the-mill thunderstorms. However, Anderson said, thunderstorms always bring a slight chance for isolated, more severe weather.

Rain chances decrease Monday, Anderson said.

Across Tampa Bay, rainfall amounts could average from 1 to 3 inches through the weekend. Some localized areas could see higher amounts. This is good news for Tampa Bay.

Areas across Tampa Bay range from abnormally dry to severe drought, according to the U.S. Drought Monitor. Coastal locations in southern counties such as Manatee and Sarasota are in an extreme drought.

Another bonus from the rain — lower temperatures, Anderson said. The addition of cloud cover will keep highs across the area in the lower-to-mid 90s.

This July is on track to be the warmest July on record for several areas across southwest Florida, including Tampa and Lakeland, according to the National Weather Service. Anderson said the extra rainfall could lower the month’s overall temperatures, and possibly knock this July from the No. 1 spot.

While the hurricane center is not monitoring the tropical wave on Florida’s east coast, it is watching a wave in the eastern Atlantic.

The tropical wave was several hundred miles southwest of the Cabo Verde Islands and has a 40% chance of formation in the next week, according to a Thursday update from the hurricane center. Forecasters said conditions are favorable for gradual development as the system moves west over the Atlantic, and it could become a tropical depression over the weekend or early next week.
