ST. PETERSBURG, Fla. — Plenty of moisture combined with heating will support scattered to numerous showers and thunderstorms through the evening. Storms will likely end during the evening.

Very weak steering winds will again support very slow moving storms so some locally heavy rainfall will be possible. It will be muggy tonight with the heat index still in the 90s this evening.

The overnight will be warm again, with lows in the upper 70s.

Friday will be partly sunny with showers and storms developing again, possibly early and near the coast. Storms will be more numerous in the afternoon and again will move slowly. Highs will be in the low 90s.

High pressure will be across Florida and the Gulf through Saturday, keeping the winds light. Storms will mainly be in the afternoon and evening and will move slowly.

Beginning Sunday, the high pressure shifts to southern Florida as a frontal trough settles in along the Gulf coast. This will set up an onshore slow pattern.

The trough settles into northern Florida by mid- week keeping a westerly flow. Plenty of moisture will be across the area for the work week, so rain chances will be a little higher than normal.

The wind pattern and plenty of moisture will keep the mornings on the warm side of normal and the afternoon temperatures around normal starting Saturday into the work week.

Expect scattered to numerous showers and thunderstorms. 

The showers and storms will start at the Gulf coast with the greatest coverage in the afternoons in the interior next week.
