Similar to yesterday morning, mid and high level clouds along the east coast are dispersing northeastward this morning with isolated showers and T'storms lingering across north central and central FL where low level convergence along a weak trough continues to feed a few T'storms. This activity will end during the next couple of hours. Patchy, shallow ground fog is possible where locally heavy rainfall amounts occurred yesterday, but no significant fog is expected. Near to slightly above average temperatures in the low to mid 70s will persist through sunrise.
As Bermuda ridge axis sinks south of the area today, a more SW flow pattern will bring in some shortwave energy aloft ahead of weak troughing over the lower and mid MS valley. This extra energy when combined with well above seasonal PWATS 1.8-2.2 inches will help spur more overall coverage of showers and T'storms compared to yesterday. Scattered showers and thunderstorms by late morning to midday will become more numerous this afternoon east of highway 301 into coastal counties as the Atlantic seabreeze slowly shifts from the coast to I-95. Isolated strong T'storms may bring gusty downburst winds of 40-50 mph where storm outflows and seabreezes collisions occur, but otherwise locally heavy rainfall rates of 2-4 inches per hour could bring locally high rainfall totals due to slow SW T'storm motion. T'storms will conglomerate along the coast by late afternoon into sunset and wane as they shift into the Atlantic waters by midnight with mid and high level clouds slowly clearing after midnight. Light southwest winds 5-10 mph will turn south to southeasterly at the beaches this afternoon.
Daytime highs will be a notch higher than yesterday with values in the low 90s for most areas with around 90 to upper 80s over inland SE GA and the Suwannee Valley where more clouds will persist from late morning onward to low 90s with peak heat indices in the low 100s. Overnight lows will be in the low 70s away from the coast and mid 70s at the coast and near the St Johns river.
SHORT TERM
(Sunday through Monday night)
Issued at 300 AM EDT Sat Jun 14 2025
Surface high pressure ridge will be across central FL on Sunday and will then drift ever so slightly northward through Monday.
Deep layer flow will be southwest both days about 8-12 knots, with elevated moisture values on Sunday with PWATS about 1.8 to 2 inches, and dropping slightly by Monday.
Sunday, fairly typical pattern and would expect to see convection develop along the west coast sea breeze and low level convergent lines over the southwest and west zones in the mid to late morning hours. Convection should continue to blossom into the afternoon and early evening as it moves toward the east coast. A concentration of convection appears likely over the eastern zones as the southwest flow meets up with the east coast sea breeze and timed with peak heating. Isolated to scattered convection in the evening will dissipate overnight with loss of heating, with movement of activity to the east-northeast.
Monday, with slightly lower moisture values and mid level ridging building, some lower POPs are warranted over what the NBM suggests, and closer to the MOS guidance, which shows 20-30 percent. Will go with a blend of NBM and the lower guidance to result in chance to likely POPs (about 40-60 percent). Convection should become scattered and isolated while diminishing Monday night with lack of any other forcing and loss of heating.
Highs will be above normal in the lower 90s, with lows in the lower to mid 70s. Heat indices will top out around 100-105 each day, mainly inland.
LONG TERM
(Tuesday through Friday)
Issued at 300 AM EDT Sat Jun 14 2025
Surface high pressure ridge will build further northward into the area Tuesday through early Thursday while temps aloft warm and drier mid level air filters into the region. This should result in subsidence and lower rain chances (to about 30-50 percent at best), but also warmer sfc temps. By late Thursday into Friday, a modest mid level trough moves into the southeast states and the sfc high will move further south. A weak cool front may move into central GA by then. This will likely result in some uptick in rain chances again so advertised up to 50-60 percent by Friday.
Could see some stronger storms by Friday given better forcing aloft and cooler mid level temps.
Advertised highs in the lower to mid 90s and lows in the lower to mid 70s.
AVIATION
(06Z TAFS)
Issued at 149 AM EDT Sat Jun 14 2025
The 06Z TAF period will begin with ceilings that are VFR levels as leftover mid and high clouds slide north and east into the Atlantic through sunrise. Shallow fog at VQQ will bring prevailing IFR restrictions with tempo restriction to VLIFR at times 07-11Z.
Light south to southwesterly winds 5-10 knots will resume a few hours after sunrise later today expected as Bermuda ridge axis sinks into central FL with some energy aloft supporting more numerous showers and thunderstorms developing by midday to early afternoon with highest storm chances from 20-24Z as the Gulf seabreeze presses well inland and merges with a more pinned Atlantic seabreeze that will turn winds south to southeasterly 6-10 knots after 18Z at CRG and JAX and by 16Z at SSI and SGJ. Thunderstorms will bring tempo restrictions for MVFR ceilings and visibility in heavier storms with gusty winds to 25 knots, but could potentially be a bit higher locally. Storms will abate after 00Z with lingering mid and high level clouds through the end of the period tonight with light southerly winds.
MARINE
Issued at 300 AM EDT Sat Jun 14 2025
Bermuda high pressure will be centered to the east through this weekend, and into next week, keeping winds generally out of the south. Each day, scattered to numerous showers and thunderstorms are expected to develop over the coast and nearshore waters before drifting eastward over the offshore waters by early evening. Seas will be 2-3 feet nearshore and 3-4 feet through the weekend and then resume to 2-3 feet across the waters into early next week.
Rip Currents: Moderate risk of rip currents are in effect today and Sunday for all area beaches through Friday.
