The calendar says autumn has begun, but South Florida’s weather on Sunday feels like summer. The day features sun, clouds, and sea breeze showers and storms. Since the winds are shifting to the east, a strong Atlantic sea breeze will push the bulk of the showers and storms to the Gulf coast and the interior. Highs on Sunday will be near 90 degrees.

Monday will start with a few east coast showers, followed by sun and clouds. Then the sea breeze will fire up some showers and storms in the afternoon, especially well inland and along the Gulf coast. Monday’s highs will be near 90 degrees in most locations and a bit cooler right along the Atlantic coast.

Tuesday will bring more of the same — a few early east coast showers, sun and clouds, and sea breeze showers and a few storms in the afternoon. Tuesday’s highs will be in the low 90s.

Look for the pattern of sun, clouds, and passing showers to continue on Wednesday. Wednesday’s highs will be near 90 degrees.

Thursday’s forecast includes sun, clouds, and showers that will be a bit more widespread. Highs on Thursday will be near 90 degrees.

In the tropics, the strong wave in the eastern Atlantic is now Tropical Storm Kirk. At 5 am Sunday, Kirk was located near 9.1 North, 28.0 West, and was moving west at 18 miles per hour. Maximum sustained winds were 40 miles per hour. Kirk is expected to be a tropical storm when it reaches the Lesser Antilles late in the week, but it will encounter hostile winds. Kirk’s future is uncertain, but we’ll watch it.
