265 FXUS62 KMLB 292319 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 719 PM EDT Tue Jul 29 2025 ...New AVIATION... .KEY MESSAGES... Issued at 252 PM EDT Tue Jul 29 2025 - Dangerous heat conditions today. An Extreme Heat Warning is in effect for areas along and north of I-4 today, with a Heat Advisory across the remainder of east central Florida. A Heat Advisory has been issued for all of ECFL tomorrow from noon to 7 PM. Heat Advisory conditions will continue for much of east central Florida for most of this week. - Residents and visitors are encouraged to take proper heat safety actions to prevent heat illness and know the signs of heat exhaustion and heat stroke. Stay cool, stay hydrated, stay informed. - Near to below normal shower and storm chances continue today, then return to near-normal through mid to late week, especially over the interior. && .PREVIOUS DISCUSSION... Issued at 252 PM EDT Tue Jul 29 2025 Rest of Today-Tonight... Mid-level ridge across TX/AR/LA region and extending across the Deep South will remain in place. The Atlantic ridge axis will begin to develop today and will build westward towards the Florida peninsula by tonight. At the surface, high pressure across the region will begin to weaken through the time period. Locally, S/SW winds will dominate and will bring a slight increase in moisture across east central Florida which will impact heat indices. The main story today will continue to be extreme and dangerous heat across the local area, especially along and north of the I-4 corridor this afternoon, including the greater Orlando area. Near record highs continue this afternoon, with highs forecast to reach in the upper 90s to near 100 degrees. These temperatures coupled with increased moisture, will produce peak heat indices of 110-115 degree. Thus, an Extreme Heat Warning remains in effect for Lake, Volusia, Orange, Seminole, and Osceola Counties until 7 PM this evening. A Heat Advisory remains in effect across the remainder of east central Florida for highs in the mid to upper 90s and peak heat indies of 108-112 degrees. The increase in moisture will also lead to a little greater coverage of convection this afternoon, mainly across the interior. There is a low to medium (30-40 percent) chance for showers and lightning storms across this area later this afternoon and into early evening. The 15Z XMR sounding shows some drier air aloft, which will support some storms becoming stronger this afternoon. Main storm hazards today will be frequent lightning strikes, strong wind gusts to 40-50 mph, and locally heavy rainfall. Any lingering activity will diminish in the evening, with overnight conditions remaining very warm and muggy. Lows are forecast in the mid to upper 70s with some spots along and NW of I-4 that are forecast not to fall below 80 degrees. This may lead to some additional warm minimum temperatures being tied or broken. Wednesday-Friday... (Modified Previous Discussion) Mid-level ridge is reinforced across the area from mid to late week, continuing abnormally hot and humid conditions across the area. The surface subtropical ridge axis will remain south of the area, producing a relatively light low level W/SW flow across the region. This will still allow the east coast sea breeze to form but will have a slower progression inland, allowing highs to still rise to the mid to upper 90s on Wednesday and low to mid 90s Thursday and Friday, as rain chances will gradually be on the rise. Still, peak heat index values are forecast to reach up to 106-112 degrees, with some areas north of Okeechobee County and the Treasure Coast potentially still nearing extreme heat conditions (heat indices near 113 degrees) on Wednesday. However, for now, have issued a Heat Advisory for all of ECFL for Wednesday from noon until 7 PM. Additional Heat Advisories will likely be need for portions if not all of east central Florida Thursday and Friday. The complicating factor remains the increase in shower and lightning storm activity through mid to late week. This increase in showers and storms will help provide some relief to the heat in the afternoon. Because of this increase in moisture and storm chances, confidence that portions of ECFL will reach Extreme Heat Warning criteria are not high. So have opted to just have a Heat Advisory for the whole area for now. Shower and storm chances rise to more normal values around 30-50 percent, with greatest storm coverage across the interior where boundary collisions are favored. A few stronger storms will continue to be possible each afternoon/evening. Saturday-Monday... (Modified Previous Discussion) A frontal boundary will shift gradually southward and stall across north Florida during the weekend into early next week, with ridge axis remaining south of the area. This will increase moisture and rain chances through the period and finally begin to put an end to the unusually hot and humid conditions. There is a medium to high (50-70 percent) chance of rain and storms across the region each day. Highs will still reach the mid 90s across much of the region Saturday, but then fall to the low to mid 90s Sunday and Monday, with peak heat index values closer to around 100-107 degrees. Overnight lows are forecast to be in the low to mid 70s. && .MARINE... Issued at 252 PM EDT Tue Jul 29 2025 Rest of today-Sunday.... Favorable boating conditions are forecast through the weekend, with hot and humid conditions persisting as a weak reinforcing Atlantic ridge axis shifts westward towards the Florida peninsula. High pressure axis will generally remain south of the area through the period. This will result in S/SW winds to dominate each day before backing to the southeast each afternoon as the east coast sea breeze forms and pushes inland. Wind speeds will generally remain below 15 KT. Seas 1-2 ft in the nearshore waters and up to 3 ft at times in the offshore waters. Isolated showers will be possible today, but coverage of showers and storms will increase mid to late week, with isolated to scattered showers and storms forecast to develop over the waters each day, especially during the morning and overnight hours. && .AVIATION... (00Z TAFs) Issued at 719 PM EDT Tue Jul 29 2025 Outflow collisions near MCO will require VCTS/TEMPO for TS another hour or so until convection subsides. There have been some occasionally strong gusts with the storms today, so monitoring those trends closely as well. On Wednesday, the dominant wind flow becomes SW`erly pushing sea breeze collisions toward the eastern half of the state. Expect scattered storms after 19Z with potentially more activity at the coastal sites as well. && .PRELIMINARY POINT TEMPS/POPS...
