Forecast Details

Early this morning...isentropic lift already evident as light/rain and drizzle showing up on the radar from dab northwest into the St Johns River basin. This will continue to develop and lift northward through sunrise.

Today...with high parked just east of the Carolinas, low level flow will remain easterly with southerly flow at 850 MB lifting over top of the shallow moisture layer. This will continue the weak isentropic lift event with light rain and drizzle possible, mainly along the coastal counties, but will spread enough inland to impact most of the forecast area with 10-30% measurable rain chances. Maximum temperatures will range from the 60s along the coastal counties to the lower 70s well inland along the I-75 corridor under mostly cloudy skies.

Tonight...isentropic up-glide will continue over the forecast area during the evening hours before fading and pushing offshore during the overnight hours. Increase in low level moisture and partial clearing skies overnight will lead to a good chance of dense fog with advisory conditions possible by morning. Mild overnight lows generally in the 50s.

Today's Pollen Levels: 7.3 High Medium(on a scale to 12); Predominate Pollen: Juniper,Alder and Oak.
