KEY MESSAGES

Issued at 302 AM EDT Wed Oct 7 2026

- High coverage of showers and occasional lightning storms through late week, with a Marginal Risk for Excessive Rainfall across east central Florida each day. Minor flooding is possible in areas that see multiple rounds of heavy rainfall.

- There is a High Risk of dangerous rip currents along the Volusia County and Space Coasts today. Entering the water is strongly discouraged!

- Periods of poor boating conditions are forecast through the end of the week, becoming hazardous this weekend.&&

DISCUSSION

Issued at 302 AM EDT Wed Oct 7 2026

Today-Tonight...Ongoing light to moderate showers near and north of I-4 are forecast to persist through daybreak, as a front remains stalled across the local forecast area. Little change overall forecast today compared to yesterday, with high coverage of showers once again expected.

Multiple rounds of showers and embedded lightning storms will traverse the area today, fueled by lift along the stationary front and deep moisture (PWATs 2.2-2.4"). This will lead to PoPs 80-90% area- wide. Low instability due to dense cloud cover from early showers will likely suppress the deepest convection and most lightning strikes across the northern half of the area today, though can't rule out a strike or two. Instead, drier conditions this morning across the southern half of the CWA is forecast to provide enough breaks in the (still dense) cloud cover for more efficient daytime heating. This will create the best chance for scattered lightning strikes and deeper convection, supported by the most recent CAM runs. Widespread rainfall totals near 2" are expected today within rounds of showers and storms. However, isolated totals near 4" cannot be ruled out embedded within deeper convection, likely across southern portions of the area. Regardless, all of east central Florida has been highlighted in a Marginal Risk (1/4) for excessive rainfall. Minor flooding will be possible, exacerbated in areas that have already seen heavy rainfall the last several days. A gust to 45 mph cannot be ruled out across the south in the strongest storms.

Showers and a few storms will persist through this evening and into tonight, especially north of the front. Thus, rainfall accumulations look to persist, though rainfall rates will be lower with a lack of deep convection. Models have backed off on the strength of the surface low forecast to develop just offshore. Therefore, forecast wind speeds this afternoon have diminished. Light and variable flow this morning becomes NE into tonight, but remains around 10 mph or less. Dense cloud cover looks to keep high temperatures in the upper 70s to lower 80s north of Melbourne, with breaks in the clouds allowing areas to the south to warm into the upper 80s. Humid conditions will support heat indices in the upper 90s to near 100 in the warmest areas.

Thursday-Friday...The stationary front is forecast to remain generally stalled across the local area through late week. Meanwhile, the Atlantic ridge nudges westward through the period, beginning to steer TD 9 northward, well west of east central Florida. A bit of rinse and repeat forecast for Thursday, as deep moisture maintains high PoPs (70-80%) across the peninsula. Multiple rounds of showers and embedded storms are expected to once again produce widespread, additional rainfall accumulations of 2", with pockets of 4" possible. Once again, the greatest chance for lightning strikes and deeper convection looks to be across southern portions of the area. By Friday, the front is expected to begin to slowly lift northward, reducing accumulations to around 1-2". However, PoPs remain around 70-80%. Will need to monitor the threat for a few spin ups Friday afternoon into Friday night, as 850 mb winds begin to veer.

The pressure gradient tightens slightly late week, as TD 9 strengthens. But, onshore flow is forecast to remain around 10-15 mph or less. High temperatures creep up a degree or two each day from south to north, as cloud cover decreases slightly. Highs return to the mid to upper 80s by Friday. Continued humid conditions will lead to heat indices in the lower 100s across the south late week.

Saturday-Wednesday...Upper level ridging over the western Atlantic is forecast to help steer what is currently TD 9 into the northern Gulf coast by Saturday. Models are in fairly good agreement that the ridge is nudged southward by a passing trough and flattened across the southern Florida peninsula late weekend, before stacking and strengthening over the northwestern Gulf early next week. Locally, high coverage of showers and storms continues Saturday, as the stalled front finally lifts northward on the eastern periphery of TD 9. Strengthening southerly flow between the ridge and TD 9 will continue to advect deep moisture into the peninsula, supporting PoPs up to 60-80% through this weekend. Breezy and gusty conditions are forecast, especially on Saturday along the coast, making for poor to hazardous beach and boating conditions. As the ridge strengthens over the Gulf, lighter northerly winds develop into next week, finally reducing PWATs and putting an end to the above normal coverage of showers and storms. In fact, could see mostly dry conditions by midweek, but the forecast maintains 20-30% PoPs for now. High temperatures look to increase and linger in the upper 80s through the period, though nearer to normal lows are possible next week.

MARINE

Issued at 302 AM EDT Wed Oct 7 2026

Models have backed off on hazardous winds across the northern waters today, with a weaker surface low just offshore. Therefore, have cancelled the Small Craft Advisories that were in effect. However, small craft should continue to exercise caution over the Gulf Stream waters, as seas up to 6 ft spread southward into tonight. Periods of poor boating conditions are forecast through late week, as onshore flow strengthens to near 15-20 kts north of the Cape at times. Then, a tightening pressure gradient on the periphery of the distant TD 9 over the Gulf will lead to hazardous southerly winds of 20-25 kts this weekend. Seas bounce around 4-5 ft, with up to 6 ft in the Gulf Stream, through the period. Regardless, high coverage of showers, with embedded scattered lightning storms is forecast through the weekend.

AVIATION

(12Z TAFs) Issued at 732 AM EDT Wed Oct 7 2026

Light to moderate showers continue this morning, primarily near and north of the Orlando terminals, and continue to mention vicinity wording further south. Patchy low ceilings have been observed at northern terminals with some uncertainty of how long cloud bases will remain below VFR thresholds. Expect rounds of prevailing light to moderate showers and few storms increasing in coverage and intensity into the afternoon. Have added afternoon SHRA TEMPOs for VIS/CIG reductions in heavy downpours, and TSRA is mentioned along the Treasure Coast where confidence is slightly better for lightning. Winds mostly out of the north to northeast today, but may become more widely variable along the Treasure Coast in vicinity of a stalled surface boundary.
