FXUS62 KMLB 261347 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 947 AM EDT Fri Apr 26 2024 ...New UPDATE, AVIATION, MARINE... .UPDATE... Issued at 945 AM EDT Fri Apr 26 2024 Quiet on the KMLB WSR-88D radar this morning. Satellite and local observations show there are a few low to mid level clouds streaming across the area. The 10Z XMR sounding shows the mid layer is beginning to moisten, with the upper layer remaining dry. Forecast soundings show PW values will increase to around 1.2" into this afternoon as low level moisture increases. Mostly sunny skies are forecast for today as surface high pressure remains in place. Easterly winds will increase into this afternoon, gusting as high as 20-25 mph. Temperatures will be seasonable today with afternoon highs in the low to mid 80s. While most areas will remain dry today, some CAM guidance shows isolated light showers/sprinkles developing across the Volusia and Brevard waters into this afternoon as low level moisture increases in the onshore flow, with some of this activity possibly making it to the coast. Thus, have added isolated very light showers along the coast from Brevard to Volusia for this afternoon. Forecast remains on track with only change being adding the sprinkles/light rain showers along the Volusia/Brevard coasts. && .AVIATION... (12Z TAFs) Issued at 945 AM EDT Fri Apr 26 2024 VFR conditions through the TAF period. Light and variable winds will become easterly by mid-morning and increase to 10-15 KT with gusts 20-25 KT possible into this afternoon. Winds will then decrease to 5- 10 KT overnight. Dry conditions through the period, although light showers/sprinkles will be possible along the coast, mainly DAB, into this afternoon. However confidence is too low to include VCSH wording at this time. && .MARINE... Issued at 945 AM EDT Fri Apr 26 2024 Favorable boating conditions through today as high pressure remains in place, with conditions beginning to deteriorate overnight. Easterly winds will increase to 10-15 KT into this afternoon, with occasional gusts to 20-25 KT possible. Winds will continue to increase into tonight, becoming 15-20 KT overnight. Seas 2-3ft today will increase to 4-5ft in the nearshore waters and 5-6ft in the offshore waters tonight. Small craft will need to exercise caution across all the waters tonight. Mostly dry conditions through tonight, however local guidance is indicating isolated light showers/sprinkles will be possible through today from Cape Canaveral northward as the low level moisture increases over the area. && .FIRE WEATHER... Issued at 345 AM EDT Fri Apr 26 2024 Today...Relative humidity values this afternoon recover some as moisture increases a bit over the area. Values in the mid 30 to low 40 percent range are expected west of I-95. Easterly winds gradually increase through the day, gusting around 20 mph at times, especially at the coast. Sat-Tue...Onshore winds increase a bit more into the weekend 15 mph/15-20 mph (Sat) with higher gusts (highest along the coast), decreasing just a bit into early next week as the pgrad relaxes slightly. Min RHs stay above critical levels on Sat-Mon, but as temperatures climb into next week, we will see values fall back to 35-40pct over the interior by Tue again. Conditions mainly dry outside of a sprinkle/brief light shower along the coast due to the deepening onshore flow (chances less than 15%). && .PREVIOUS DISCUSSION... Issued at 345 AM EDT Fri Apr 26 2024 Today-Tonight...Calm conditions are in place to start the day across east central Florida. Temperatures range from the low 60s to the low 70s (coast) under a mostly clear sky. RAP analysis and satellite imagery indicate some mid level cloud development over northern portions of coastal Volusia county and the adjacent waters, due to some saturation around 800-850mb. Surface high pressure is forecast to stay locked in place as mid level ridging builds east from the Gulf of Mexico today. Easterly winds will pick up this afternoon, gusting as high as 20-25 mph, with temperatures reaching seasonable levels in the low to mid 80s. At the beaches, a high risk of rip currents exists, so entering the water is discouraged. Sat-Sun...Mid-upper level ridging will encompass much of the Eastern Seaboard thru the weekend. Mid-level impulses will occasionally slide down the peninsula, though we continue to retain mostly dry conditions with a stable onshore flow and less than modest moisture. However, will not rule out a few showers across the local coastal waters and cannot entirely rule out some spits/sprinkles along the coast due to the deep, persistent, onshore flow. Surface high pressure will dominate across much of the eastern CONUS. The pgrad will be tight enough for breezy conditions each afternoon, especially along the coast. Expect gusts of 20 to 25 mph to be common, with 30 mph within reach along the immediate coast (esp Sat). Afternoon highs in the U70s to around 80F at the coast and L80s into the interior. Overnight lows mild and well into the 60s each early morning. Mon-Fri...The upper ridging begins to break down and shift off of the Atlc Seaboard into the western Atlc. Initial surface high pressure off of the Carolinas will also continue to weaken thru mid-week, while gradually shifting southward, then further seaward by the end of the work-week. The onshore surface flow stays mostly intact, with winds gradually veering a bit more SE/S, though the pgrad will slowly weaken during this time. Continue to keep conditions over land dry. Again, overall (low) coverage potential at the moment, keeping mention of a sprinkle/brief light shower along the coast out of the grids/zones. A warming trend will ensue, with L80s at the immediate coast, perhaps some M80s here by Thu/Fri, and M-U80s into the interior - perhaps some readings near 90F or just above into the interior Wed-Fri. Overnight lows remain consistent and in the 60s areawide. && .PRELIMINARY POINT TEMPS/POPS...
