FXUS62 KMLB 232008 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 408 PM EDT Tue Apr 23 2024 .DISCUSSION... Issued at 324 PM EDT Tue Apr 23 2024 Tonight/Wed...High pressure slipping off the Carolina coast this aftn will continue eastward over the Atlc with a trailing ridge axis extending westward across north FL. Winds will become East and decrease a bit compared to today as pressure gradient relaxes. There should also be more sun as marine stratocu will not be as prevalent though still present. Cool overnight lows in the mid to upper 50s interior and lower 60s coast. A little warmer Wed with max temps in the upper 70s coast and mid 80s interior with low humidity. Thursday-Friday...A surface ridge axis in place across the Florida peninsula becomes stretched across the western Atlantic as a surface boundary sinks towards north Florida. Dry conditions prevail through the end of the work week under mostly sunny skies. An east coast sea breeze is forecast to develop each afternoon, keeping coastal temperatures near seasonal values in the low 80s. Warmer west of I- 95, climbing into the mid to upper 80s. Saturday-Monday...Reinforcing high pressure builds across the western Atlantic. Locally, onshore flow will increase to 10-15 mph each afternoon. Moisture increases into Saturday with skies becoming partly cloudy. Soundings suggest enough moisture in the low levels to support onshore moving cumulus and perhaps a shallow shower along the coast this weekend. NBM PoPs remain dry, but have continued a mention of silent PoPs (~10-14%) over the waters and along the coast Saturday afternoon. Breezy onshore flow should keep coastal counties in the low 80s while interior counties remain in the mid to upper 80s. && .AVIATION...

On Wed, East winds 5-10 knots interior and 10-14 knots coast. && .MARINE... Issued at 324 PM EDT Tue Apr 23 2024 Tonight/Wed...Gradually improving conds as Atlc high pressure ridge axis settles south across north FL. Winds will become E to SE 5-10 knots tonight, becoming enhanced by the sea breeze near the coast Wed aftn at 10-14 knots. Seas will fall below 7 feet in the Gulf Stream this evening so what is left of the SCA will be allowed to expire. On Wed, seas 4 to 5 feet mainly in a NE swell. Friday-Sunday...High pressure holds influence over the local Atlantic waters into the weekend. Onshore flow becomes breezy Friday night increasing to around 15-20 kts. Seas of 2-3 ft on Friday steadily increase this weekend, becoming 5-6 ft Saturday night. While mostly dry conditions are forecast to persist, a light shower could be possible on Saturday (~10%). && .FIRE WEATHER... Issued at 324 PM EDT Tue Apr 23 2024 Much drier airmass across the area through mid to late week will continue sensitive fire weather conditions across the area. Critically low RH values are forecast each afternoon, mainly over the interior, as easterly onshore flow will keep RH values elevated along the coast. Min RH values will drop as low as the upper 20s to mid 30s Wednesday and Thursday, and mid to upper 30s Friday. Wind speeds across the interior, where critically low RH values are expected, look to remain below 15 mph Wednesday and Thursday, but may approach around 15 mph on Friday afternoon as onshore flow increases. && .PRELIMINARY POINT TEMPS/POPS...
