341 FXUS62 KMLB 142324 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 724 PM EDT Tue Jul 14 2026 ...New AVIATION... .KEY MESSAGES... Issued at 725 PM EDT Tue Jul 14 2026 - Scattered to numerous showers and storms will diminish late this evening. Another round of a few storms is forecast on Wednesday. The strongest storms will carry a risk for wind gusts of 40-50 mph. - Hot and humid temperatures will lead to afternoon heat indices between 102-107F each day. Make sure to practice heat safety! && .DISCUSSION... Issued at 250 PM EDT Tue Jul 14 2026 Rest of Today-Tonight... Latest radar and satellite imagery depict a west-east oriented cluster of showers and storms currently moving across northern Lake and Volusia counties. This activity will continue to track E/SE this afternoon with expanding areal coverage of convection southward across the area in response to sea breeze and outflow boundary interactions. SPC maintains a Marginal Risk (level 1 of 5) of isolated severe storms for ECFL through this evening carrying a primary risk of damaging wind gusts, as noted in the most recent MCD highlighting a localized wet microburst potential with stronger convection. A few areas of localized flooding in low-lying and poor drainage areas also remain possible with heavier and quickly accumulating rainfall locations. Convection expected to push offshore late evening into tonight with mostly clear to partly cloudy conditions settling in overnight. (from previous discussion)... Wednesday-Thursday...Low level W/SW flow continues with ridge axis over the West Atlantic near to south of the area. Model guidance does show even drier air from the SAL moving into the area, with the GFS showing PW values on Wednesday dropping to as low as 1.5-1.6 inches. However, models have struggled with the amount of dry air and even NBM has been increasing PoPs slightly for this period as we get closer in time. However, for now the forecast for lower convective coverage continues, with PoPs ranging from 20-40% each afternoon/evening. The low level offshore flow and sea breeze collision will continue to generate at least isolated to scattered showers and storms across the area, with a few stronger storms still possible. The decrease in convective coverage will only allow temps to increase, with more widespread mid 90s for max temps across the area. Drier air aloft should mix down leading to a decrease in afternoon dewpoints (as low as upper 60s/low 70s across the interior), but with the hot temps will still lead to peak heat index values 100-107F. Friday-Monday...Mid level ridge extending from the Atlantic and across the southeast U.S. will gradually break down as trough digs southward across the eastern United States through the weekend into early next week. This will keep surface ridge axis near to south of the area. Moisture gradually rises through the period, with afternoon/evening shower and storm chances increasing and returning to more normal values (PoPs around 30-40% Friday and then 40-50% for much of the area Saturday-Monday). No relief from the July heat is in sight, with max temps forecast to continue to range from the low to mid 90s. The added humidity may even push peak afternoon heat index values a little closer to Heat Advisory thresholds (108-110F) in some spots. However, most for most areas values still look to mostly range from 102-107F. && .MARINE... Issued at 250 PM EDT Tue Jul 14 2026 (modified previous discussion)... Boating conditions will remain generally favorable through the rest of the week and into early this weekend, outside of offshore moving thunderstorms during the afternoon and evening hours. High pressure ridge axis over the west Atlantic will remain near to south of the waters, maintaining generally west-southwest winds during the overnight and morning hours, switching to the south-southeast into the afternoon/evening as the east coast sea breeze forms. Wind speeds are forecast to remain mostly below 15 knots, with seas 1-3 feet. Scattered to numerous offshore moving storms remain possible this afternoon and evening, and will be capable of producing strong to locally severe wind gusts up to 35-50 knots and frequent lightning. Coverage of storms then decrease into mid to late week, becoming isolated to scattered, but a few strong offshore moving storms will still be possible during the afternoon and evening hours. && .AVIATION... (00Z TAFs) Issued at 725 PM EDT Tue Jul 14 2026 We continue to track a band of showers and storms with gusty winds affecting MLB, with potential impacts shifting toward VRB/FPR over the next hour if they continue to form to the south. Peak gusts to 35 KT have occurred. Quieter conds are forecast late tonight and thru Wed AM. By the afternoon, there remains significant uncertainty in the guidance regarding TS redevelopment. For now, we think a few storms should form with motions E/SE toward the coast in the afternoon/early evening. At MCO, storm development should be beyond 17Z. Outside of storms, light/vrb winds turning WNW up to 10 KT on Wednesday, except easterly up to 10 KT at the coastal terminals MLB southward in the afternoon. && .PRELIMINARY POINT TEMPS/POPS...
