Hazardous Weather Outlook:


...LOCALLY HEAVY RAINFALL EXPECTED TODAY...


Numerous showers and embedded thunderstorms are expected across the forecast area today. storm total rainfall amounts of 2 to 4 inches will be possible. Minor flooding of low lying areas and ponding of water on roadways is expected.


Breezy conditions are expected along the coastal areas through tonight with gusts up to 30 mph possible at times. a lake wind advisory may be required depending on the eventual track of Tropical Depression 16


Forecast Details: numerous showers and embedded thunderstorms expected to re-develop area wide as middle/upper level trough pulls deep tropical moisture back north over the forecast area with precipitation water amounts exceeding 2 inches in most areas. This deep layer moisture and lift will interact with old frontal boundary lingering across the forecast area. Skies will be mostly cloudy but temperatures will only have to bump upwards about 10 degrees to make it into the lower to middle 80s. Have kept mention of locally heavy rainfall as upper level dynamics will help any rain bands that develop to produce occasional heavy rainfall.


Tonight, d/upper level low over the southeastern U.S. will pinwheel a dry slot into the region as low level lead baroclinic low will push just east of the forecast area over the coastal waters and this will end the heavy rainfall threat with rainfall chances decreasing from west to east. Tropical Depression 16 will follow lead baroclinic low and will be about 150 miles east of Jacksonvilleby early Thursday morning. Still not expecting much wind on the western side of the system over the land based areas.


Today's Pollen Levels: 4.6 Low Medium (on a scale to 12); Predominate Pollen: Ragweed, Grass and Chenopods.
