Tonight: Partly cloudy. Slight chance of showers and isolated thunderstorms in the evening. Patchy fog after midnight. Lows in the lower 70s. Southeast winds 5 to 10 mph. Chance of rain 20 %.
Scattered to isolated thunderstorms are expected today. storm motion will be north to northwest 10 to 15 mph. Isolated storms will likely initiate by afternoon across northeast Florida, then scattered storms are expected this afternoon across southeast Georgia and toward the I-75 corridor across north Florida. Tthe main convective concerns will be frequent lightning and gusty winds.
Forecast Details: an upper level low was retrograding over northeast Cuba with spokes of energy rotating around the vortex, including one that was enhancing thunderstorms and rain across South Florida this hour. Water vapor imagery indicated a swath of dry middle an upper level air rotating over the County Warning Area with the blended total precipitation product indicating precipitable waters of 1.75 inches advancing over northeast Florida from the southeast while the 2+ inch band shifted northwest of the area. The surface ridge axis across central Florida was edging northward. Locally patchy fog and low ceilings were developing due to wet grounds and near calm winds.
As the upper low moves toward the Gulf of Mexico the piece of energy that was impacting south Florida will translate northward across our Florida and western Georgia zones today. Precipitable waters will remain below 1.8 inches so precipitation will not be as widespread as the past couple of days, but forcing and instability will be in place to spawn scattered thunderstorms and rain late this morning across most zones with the focus shifting inland toward the I-75 corridor this afternoon and evening. The main convective concerns will be frequent lightning in stronger storms as well as gusty winds for interior zones where NAM BUFR model soundings indicated moderately steep middle level lapse rates.
Today's Pollen Levels: 3.2 Low Medium (on s a scale to 12); Predominate Pollen: Grass, Chenopods & Nettle.
