NWS Melbourne, FL wrote its last area forecast discussion before the first event at Apr 14, 9:26 AM EST, 4 hours 50 minutes earlier.
Area Forecast Discussion National Weather Service Melbourne FL 1026 AM EDT Fri Apr 14 2023 ...New UPDATE, PREV DISCUSSION... .UPDATE... Issued at 1001 AM EDT Fri Apr 14 2023 Not a whole lot going on across east central Florida with KMLB radar imagery currently showing just isolated showers across the adjacent Treasure Coast waters. However, analysis charts indicate that a cut-off low remains over the Southeastern CONUS with an uptick of shear and instability located downstream of the low across east central Florida. The morning observed XMR skew-t sounding also signaled this with about 1,500 J/kg of CAPE, DCAPE around 1,000 J/kg, 30kts of bulk shear, and a PWAT value of 1.5." Meanwhile, modeled afternoon skew-ts show increasing instability and shear into the afternoon hours, especially towards the Treasure Coast with the development of the east coast sea breeze. With that said, moderate to high instability, sufficient bulk shear, conditionally unstable lapse rates, as well as an uptick in SCP and SHIP values into this afternoon should be conducive for isolated strong storms with the capability to produce: wind gusts of 40-50mph, heavy rainfall, and cloud to ground lightning strikes. Afternoon highs are on track to reach the mid 80s to near 90 degrees. && .PREV DISCUSSION... Issued at 1001 AM EDT Fri Apr 14 2023 Current...Vertically stacked low centered over northern MS/AL continues to drift north, while its surface reflection weakens. To its east, S-SSW wind flow continues over the FL peninsula, between the low and the Atlantic surface high. After a period of clearing behind Thu evening's strong convection, areas of mid and high clouds redeveloped across the area a little after midnight, and continue overhead. Some fog has developed to the west of the CWA, but none across ECFL thus far. Otherwise, another mild early morning ongoing with 3AM temps in the U60s-L70s. Today-tonight...Mid level low associated with the system to the NW ejects rapidly NE across the TN Valley today, then up through the northern spine of the Appalachians by tonight as flow aloft veers slightly from SW to WSW. At the surface, light southerly surface winds will give way to the local sea breeze circulations in the afternoon. Sufficient low level moisture expected for scattered (30 POPs for all but Lake Co.) diurnal convection, mainly along local boundary interactions. As mid level heights start to rise, so will temps aloft (to -10C by late afternoon). The combination of slightly less mean moisture and instability should limit the strength of today's storms compared to Thu. However, a few will still be capable of producing brief 30-40 mph wind gusts, heavy downpours and CG lightning strikes. A shower/TS or two may linger past sunset, but weaken by mid evening. Max temps in the U80s, with mins in the L-M60s. Saturday...A mid level cut off low will continue to lift northeastward on Saturday. Locally, the associated surface boundary will continue to move offshore into the Atlantic. In its wake, a broad surface trough will develop across the Florida peninsula. With modeled PWATs ranging between 1.2-1.4" a few showers cannot be ruled out within vicinity of the surface trough, and a slight chance of showers has been included across the interior, generally south of Orange county. It will be warm on Saturday with highs climbing into the upper 80s and localized areas in the low 90s west of Interstate 95. Temperatures generally in the mid 80s to the east with low 80s on the immediate coast. Sunday...A 500mb trough over the central U.S. will move eastward on Sunday before closing and lifting towards the northeast. A mid level short wave and surface cold front associated with the low will move across the Florida panhandle Sunday reaching east central Florida Sunday night. Models continue to be in disagreement in precip coverage. 00Z model guidance shows a much wetter ECM solution than the GFS. Have populated Sunday PoPs with NBM guidance, but have elected to cap PoPs at 50 percent due to continued inconsistencies in global model guidance. Sunday will continue to be unseasonably warm with lower 90s across much of the interior. Highs in the upper 80s east of Interstate 95 with mid 80s along the immediate coast. Monday-Friday...The cold front will continue to push south of the local area on Monday with coverage of showers decreasing from northwest to southeast as the front eventually stalls around the Florida Straits. Surface high pressure will begin to build on Tuesday, and a very dry airmass will be in place Tuesday and Wednesday (PWATs ~ 0.4"). As high pressure retreats northeast late week, moisture will rebuild helping to increase PoPs. Temperatures cool some behind the front. Highs in the low to mid 80s Monday and Tuesday with areas of the Volusia and Brevard coast only topping out in the upper 70s. Temperatures will warm through the remainder of the week with upper 80s returning across the far interior by Friday. && .MARINE... Issued at 345 AM EDT Fri Apr 14 2023 Today-tonight...Continued improvement in boating conditions with weakening winds...S-SW around 10kt backing SE along the coast in the afternoon. Seas 3-5ft early this morning subsiding to 3-4ft this afternoon and 2-3ft late tonight. Saturday-Tuesday...Variable winds around 5 kts on Saturday will become south on Sunday around 10 kts. Winds increase and veer through the remainder of the period becoming north around 10-15 kts on Tuesday behind a cool FROPA. Seas of 2-3 ft will begin to build on Monday with 4-5 ft seas across the offshore zones on Tuesday. && .AVIATION... (06Z TAFS) Issued at 345 AM EDT Fri Apr 14 2023 VFR. Lower coverage/intensity of SHRA/TS today, with the coastal aerodromes perhaps slightly more favored for VCTS this afternoon. Will consider whether to add VCST to any interior aerodromes for the 12Z package. && .PRELIMINARY POINT TEMPS/POPS...

Scattered showers and isolated lightning storms are forecast to develop across east central Florida during the late afternoon and early evening hours, with perhaps a slightly better chance over the coastal counties once again. Storm motion today will be toward the east-northeast at 20 to 25 mph. The strongest storms will be capable of producing wind gusts up to 40 to 50 mph, heavy downpours of 1 to 2 inches, and cloud to ground lightning strikes. Move indoors to safety at the first sign of threatening skies, or if you hear thunder. .MARINE THUNDERSTORM GUST IMPACT... Storms will also be capable of producing wind gusts to 35 knots on area lakes, the Intracoastal Waterway and nearshore Atlantic during the late afternoon and early evening. .RIP CURRENT IMPACT... A Moderate risk of dangerous rip currents will exist at area beaches today. Check with the local beach patrol for additional information about ocean hazards, and always heed the advice of lifeguards. Swim only within sight of a lifeguard, and never enter the ocean alone. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY. A cold front will approach central Florida late Sunday night and move across the area on Monday. Showers and lightning storms will accompany the front as it moves through the region. Winds and seas will also increase as the front approaches and pushes across the local Atlantic. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today and tonight. Fehling
