Plan your trip Local Radar Detailed Forecast

Today: Partly cloudy. Chance of showers and slight chance of thunderstorms in the morning then chance of showers and thunderstorms in the afternoon. Highs in the lower 90s. South winds 5 to 10 mph. Chance of rain 50 %. Heat index readings 101 to 105.

Tonight: Partly cloudy. Chance of showers and thunderstorms in the evening then slight chance of showers and thunderstorms after midnight. Lows in the lower 70s. Southwest winds 5 mph. Chance of rain 40 %.

Scattered to numerous showers and thunderstorms are expected today. Most of the activity is expected across northeast Florida this morning and southeast Georgia this afternoon and evening.

Slow movement of the convection toward the northeast at 10 mph or less will allow for locally heavy rainfall in some locations. Gusty winds and frequent lightning will be possible in thunderstorm activity this afternoon and evening.

Maximum temperatures in the lower to mid 90s along the I-10 corridor and northward across southeast Georgia will push heat indices into the 100 to 105 degree range this afternoon.

Forecast Details: a low level boundary is clearly evident on satellite imagery which extends from 31.5w 78w & 30n 80w from Matanzas Inlet to Ocala and then to Steinhatchee, Dog Island and Apalachicola. This boundary may be part of the frontal boundary analyzed to the north across central Georgia as most fronts in this are and this time of year are pretty diffuse anyway. Bottom line is this boundary has been the focusing mechanism for convection this morning with heavy rainfall over Levy and Dixie counties and will continue to do so this afternoon. Expect locally heavy rainfall especially from State Road 16 southward as the boundary meanders across the area. North of there early morning stratus will gradually break up but will serve to hold down temperatures for a while. Eventually we will reach convective temperature across the remainder of the forecast area with widely scattered convection breaking out north of Florida State Road 16. Otherwise small craft exercise caution conditions are continuing across the offshore waters and may keep up though the day.

Today's Pollen Levels: 7.4 Medium High (on a scale to 12); Predominate Pollen: Ragweed, Grass and Chenopods.
