ST. PETERSBURG, Fla. — Here's your Tampa area weather forecast for late Friday into Saturday morning, along with a look at conditions through Labor Day weekend. 

  • Afternoon thunderstorms
  • Some heavy rain
  • More Labor Day weekend storms

Scattered storms will again have a westward movement into the gulf this evening. Expect clearing skies overnight into early Saturday morning. 

Lows will be in the low to mid 70s.

This pattern with a wind blowing from the east is the same one we will see all weekend long. 

Saturday morning will start out dry. Storms will develop on the east coast and the interior of the state in the afternoon and will move west.

Highs will be into the 90s before the rain moves in, which will cool temperatures into the 70s. Winds will be a little lighter than the last two days.

Sunday afternoon will again be in the low to mid 90s. Storms will develop in the afternoon.  East breezes pick up again, so storms will bring gusty winds.

The coverage of storms will be at about 50 percent both days. 

The east wind pattern will continue into Labor Day, also. The difference though for early week next week will be that we have more moisture in our atmosphere.

There is a tropical wave to our southeast that will be passing by to our south Monday into Tuesday. When that happens it will increase our atmospheric moisture, which in turn will result in a higher coverage of showers and storms passing through the area at that time.

Expect the coverage of storms back up to about 60 percent Monday, and then likely up to 70 percent Tuesday. If the wave moves by faster, Monday rain coverage may be a bit higher, and Tuesday coverage a little lower.

Behind that wave the moisture will slowly decrease. with rain chances down to about 50 percent Wednesday and then 40 percent by Thursday.

But even when the rain chances decrease, the pattern will remain the same, where the storms are in the afternoon to evening and move westward toward the gulf.

Highs will be in the low to mid 90s most days, but coolest on Tuesday when we have the most clouds and highest rain chance. It will likely be in the 80s that day.
