Today: Partly cloudy. A 20 % chance of a shower in the afternoon. Highs in the lower 90s. North winds 10 to 15 mph.

Tonight: Partly cloudy in the evening then clearing. Lows in the mid 60s. West winds 5 to 10 mph.

Forecast Details: Hurricane Earl position near 28.6 north 74 west at 06z heading north-northwest at 18 miles per hour with outflow noted to the north and south of the area and our County Warning Area in subsident/dry region aloft. The JAX 06z sounding though shows significant moisture under the subsidence inversion which is near 830 mb or about 6000 feet. Mean 0-6km flow has back in response to Earl with winds at 060 degree and decreased to 13 knots. Small showers occasional affecting the coast per radar imagery in low level moisture convergence areas which is maximized along the coast and coastal waters. Aloft...middle level ridge is noted over the middle Atlantic and then southwestward to Alabama and Mississippi. Patchy fog has developed in a few areas due to lighter flow and sufficient low level moisture.

As Earl heads northward then northeastward today-Saturday expect the mean flow to back around westerly component with a warming trend. Generally warm and dry airmass is expected with highs going back up into the lower to middle 90s over most of the region on Friday and Saturday. The models continue in good agreement show a "dry" cold front marching southeastward on Friday night and Saturday into the southeast states and across our forecast area on Saturday. Overall little change in sensible weather expected Saturday

Today a mostly dry northward flow sets up today with breezy conditions possible near the coast/beaches. Highs in the upper 80s to lower 90s expected. Models seem a little lacking showing the low level moisture present and feel there is a small chance for showers over the eastern/southeastern zones today. This chance though will likely shift southward during the day where low level convergence will focus mainly south of a St.Augustine-Gainesville line. Therefore used a blend of models to come up with 15-20% probability of precipitation for eastern zones today. Subsidence aloft will likely prevent any deep convection. Tonight high pressure ridge builds in from the south as Earl pulls away. Cooler lows expected as moisture levels decrease.

Today's Pollen Levels: 8.7 Medium High (on a scale to 12); Predominate Pollen: Ragweed, Grass and Chenopods.

Did you know that...

The Labor Day hurricane hit the Florida Keys on this date in 1935, killing over 400 people. The storm created waves nearly thrity feet high and the lowest barometric pressure was measured at 26.35 inches near Matecumbe Bay, Fla., which was the lowest reading until Hurricane Gilbert in 1988.
