| Area Forecast Discussion National Weather Service Melbourne FL 653am EDT Wednesday April 22 2026 Issued at 223am EDT Wednesday April 22 2026 Current - Tonight Fairly sharp temp gradient early in the period with M-U50s over the far interior and U60s to near 70F along the coast. Onshore winds near 10-15 mph for the immediate coast and mainly 5 mph or less across the interior. Generally dry conditions continue, save for isolated light rain showers or sprinkles across the local coastal waters and maybe a 10% chance along the coast, highest chances "might" be coastal Volusia and coastal Brevard. As weak high pressure ridging settles near north-central FL, the pressure gradient will slowly begin to relax. We still maintain 10-15 mph over the interior this afternoon and around 15 mph or a little higher at the coast, with stronger afternoon gusts likely. Partly sunny skies with a few more clouds along the coast due to the low-level onshore flow. Max temps in the U70s along the coast and near 80F to L80s into the interior. Similar overnight mins upcoming with M-U50s to near 60F over the interior and 60s to near 70F, again, along the coast. Thu-Tue...Flow aloft continues W/NW thru the period with periodic weak shortwave impulses traversing the FL peninsula. At the surface, weak high pressure ridging across the central FL peninsula eventually gets nudged seaward and southward later in the weekend and early next week. This will keep the pressure gradient rather weak thru much of this period. Will see some modest increases in moisture Thu into the weekend as well as daily sea breezes with a collision across the western peninsula Thu evening, gradually moving closer towards the central FL peninsula thru this weekend. We may see some isolated showers develop into the interior Thu afternoon, with isolated (20%) lightning storm chances Fri-Sat, then maybe low-end SCT (30%) threat on Sun, before returning to isolated again for Mon. Any potential frontal passages stay mainly northward. Near seasonal high temps Thu, then a warming trend ensues Fri-Tuesday with max values approaching M-U80s and potential 90F over the interior (Sun-Tue). Onshore flow will continue to keep coastal areas in the 60s to near 70F for mins, and drier air will allow interior locations to dip into the M-U50s one last morning Fri, with 60s returning almost areawide Sat-Wednesday mornings. Marine Issued at 223am EDT Wednesday April 22 2026 Will allow Small Craft Advisories to expire, though Cautionary Statements will greet the new day across the Treasure Coast waters for this morning. Conditions gradually improve through Thu as the pressure gradient continues to relax as a weak low-level ridge axis settles closer to central FL. A more S/SW flow will develop Fri-Sat as the ridge axis passes overhead, then south of the local waters on Sun. An E/SE sea breeze 10-15 knots will develop each afternoon near the coast. Seas returning to 3-5 ft areawide later this morning, then 3-4 ft into Thu, 2-3 ft Fri, and 2 ft Sat-Sun. isolated light sprinkles/showers will develop today/tonight, with isolated widely scattered aftn/evening lightning storms returning Sun/Sunday night. Fire Weather Issued at 223am EDT Wednesday April 22 2026 High pressure ridge axis will settle southward and reach central FL later this week, allowing onshore flow to gradually decrease today and especially Thursday/Friday. East winds will not be quite as strong today but still gusting 20 to 25 mph especially along the coast; then gusting 15 to 20 mph Thursday. Isolated Atlantic showers may cross portions of the coast today. Min RH values of 35-40% are forecast over the interior this afternoon so Red Flag conditions are not forecast, though it will be a fire sensitive day as dispersion values will continue to be Very Good to Excellent. Dispersions fall slightly Thursday/Friday as surface and transport winds decrease. NOAA Melbourne FL Office: Watches - Warnings - Advisories FL...None. AM...None. |
