606 FXUS62 KMLB 121802 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 202 PM EDT Thu Jun 12 2025 ...New AVIATION... .KEY MESSAGES... Issued at 230 AM EDT Thu Jun 12 2025 - Scattered to numerous showers and storms forecast over the next several days, with greatest rain chances (up to 50-70%) focused across the interior during the afternoon and through sunset. - Seasonably hot temperatures, with highs in the upper 80s to low 90s, continue through late week and into the weekend, with peak heat index values 100-105F. - A Moderate Risk for rip currents continues at area beaches. && .PREVIOUS DISCUSSION... Issued at 230 AM EDT Thu Jun 12 2025 Today-Friday...West Atlantic ridge axis remains near to just north of central Florida through late week, which will continue a relatively light low level southeasterly flow across the area. PW values remain around 1.8-2.0 inches today, and decrease to 1.6-1.8 inches on Friday. This moisture will be sufficient for scattered to numerous showers and storms to form along and ahead of an early developing east coast sea breeze. Onshore flow will allow sea breeze to push well inland through the afternoon, with greatest convective coverage focusing inland and toward the western side of the FL peninsula where boundary collisions will be favored. Rain chances are around 50% along the coast each day and for inland areas will range from 60-70% this afternoon and around 50-60% on Friday afternoon as drier air and ridge aloft building in from the east should lower coverage slightly. A low threat for isolated strong storms will continue, again mainly inland, with main threats being frequent lightning strikes and strong wind gusts up to 40-50 mph due to drier air aloft. Weak steering flow out of the S/SE may also allow for some storms to produce locally heavy rainfall of 1-3" leading to ponding of water along roadways and poor drainage areas. Hot and humid conditions will continue, but highs will generally be near normal in the upper 80s/near 90 along the coast and low 90s across the interior, with peak afternoon heat index values of 100- 105F. Saturday-Wednesday...Surface ridge axis of high pressure across the west Atlantic will begin to slowly shift back southward and across the region late weekend into early next week. Aloft, a ridge will remain extended across Florida. PW values into the weekend remain around 1.6-1.8 inches, with the potential for even drier air to build into the area into next week. Low level S/SE flow will allow sea breeze to develop and push inland each afternoon, with sea breeze collisions favored near to NW of the I-4 corridor. Scattered shower and storm development will continue, mainly during the afternoon and early evening hours, but greatest rain chances will continue to be focused inland. PoPs will range from 30-50% along the coast up to 40-60% inland through the weekend into early/middle portion of next week. Warming temps aloft will keep threat for any stronger storms low, but still can`t rule out isolated storms producing strong wind gusts to 40-50 mph as drier air aloft lingers. Additional storm threats of frequent lightning strikes and locally heavy downpours will also continue. Temps remains near to slightly above normal into the weekend, with highs in the upper 80s/low 90s and peak heat index values of 100- 105F. Into early to middle portion of next week, temps will gradually climb as sea breeze won`t be able to move as quickly inland and storm coverage will likely be lower. Highs gradually rise to the low to mid 90s, with peak heat index values 102-107F. && .MARINE... Issued at 230 AM EDT Thu Jun 12 2025 Today-Monday...West Atlantic ridge axis remains near to just north of the waters over the next few days, before starting to settle southward and back across the region late weekend into early next week. This will keep boating conditions generally favorable through the period, with S/SE winds prevailing and wind speeds largely remaining below 15 knots. Seas will continue to range around 2-3 feet through the period. Main concern for boaters will be isolated to scattered storms that will develop over the waters, especially during the nighttime and morning hours. This activity will move toward the N/NW, with some storms potentially pushing onshore. Main storm threats will be cloud to water lightning strikes and gusty winds. && .AVIATION... (18Z TAFs) Issued at 200 PM EDT Thu Jun 12 2025 Mainly VFR forecast thru the TAF period, outside of TSRA impacts inland and brief MVFR CIGs. The east coast sea breeze (ECSB) continues inland this afternoon, with SHRA/TSRA forming along with it. TEMPOs remain but were moved up by an hour at MCO/ISM/SFB/LEE, and local gusts of 30-35+ kt cannot be ruled out. Activity gradually diminishes after 23z-01z over interior sites (see VCSH thru 03z at LEE). Light SE winds overnight return to 8-12 kt after 15z Fri. with winds veering more E as the ECSB moves inland by the end of the TAF. && .PRELIMINARY POINT TEMPS/POPS...
