415 FXUS62 KMLB 222312 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 612 PM EST Sat Feb 22 2025 ...New UPDATE, AVIATION... .KEY MESSAGES... Issued at 217 PM EST Sat Feb 22 2025 - Boating conditions improve into next week, while a high risk of rip currents remains at area beaches today - Increased rain chances forecast for Monday, as an area of low pressure traverses south-central Florida, then drier mid to late week - Near to slightly below normal temperatures into next week && .UPDATE... Issued at 612 PM EST Sat Feb 22 2025 Forecast remains on target this evening, with no significant impacts occurring across the district. A stream of high-level cloud cover will persist for the next few hours before clearing occurs overnight. Low temps within a few degrees of climatology for late February standards, and a pleasant Sunday is still in store. && .PREVIOUS DISCUSSION... Issued at 217 PM EST Sat Feb 22 2025 Rest of Today-Sunday...High pressure lingering over the local area today will break down into Sunday, as a shortwave trough digs into the Gulf. Dry conditions will continue to prevail, with mostly cloudy skies today yielding to partly cloudy during the day on Sunday. Clearing skies will allow for temperatures to warm a few degrees tomorrow afternoon, becoming close to normal in the lower to mid-70s. Prior to that, near to slightly below normal temperatures will persist through tonight, with lows in the 50s for most areas, with the exception of upper 40s well north of I-4. Onshore flow today will veer northerly into Sunday morning, as a weak shortwave trough dips through the local area overnight. Sunday Night-Monday...A weak surface low pressure system is forecast to develop over the Gulf along the shortwave digging into the southern US early next week. Models have come into somewhat better agreement this cycle about the track of this system, taking it eastward through the northern Gulf Sunday night, then across the south- central Florida peninsula on Monday. With higher confidence in the models, have increased peak PoPs across the area to 60-70% from Orlando southward and 50-60% north of I-4. Coverage will begin to increase late Sunday night, before peaking through the day on Monday. Rainfall accumulations have also increased, with areas south of Orlando forecast to see accumulations of 1-2". A few locally higher totals around 3" cannot be ruled out, with PWATs forecast between 1.2-1.6". However, with nearly all of east central Florida in D0-D1 drought, with the exception of most of Indian River and St Lucie Counties, overall accumulations are expected to be beneficial. A few lightning storms cannot be ruled out along the Treasure Coast Monday afternoon, but forecast CAPE is low (MU CAPE <500J/kg) High coverage of clouds and precipitation are forecast to keep Sunday night low temperatures in the 50s. But, with limited direct sunlight, forecast highs Monday will once again be below normal, in the upper 60s to lower 70s. Tuesday-Friday (modified previous)...We shift to a drier pattern from midweek onward with only lingering showers near Lake O and the coast on Tuesday and a 10-15 percent (or less) chance of a sprinkle or shower along a cold front Thursday night into Friday. Timing differences exist with the FROPA on Friday, with some models suggesting a late Thursday night arrival, while others are trending toward Friday morning/midday. Lighter winds on Tuesday- Wednesday are forecast to increase Thursday afternoon ahead of the front, veering northwest and becoming breezy in the wake of the front on Friday. Daytime temperatures will climb closer to normal Tuesday and slightly above normal on Wednesday/Thursday, especially across the south. Overnight forecast lows range from the upper 40s (far north Lake/Volusia) to the mid/upper 50s everywhere else. Post- frontal temperatures briefly cool down Friday night, dropping back into the 40s and low 50s. Previewing next weekend and the first couple days of March, pleasant conditions with near to slightly above normal temperatures are possible as high pressure builds over the southeastern U.S. && .MARINE... Issued at 217 PM EST Sat Feb 22 2025 Boating conditions will continue to improve overnight tonight into Sunday, as high pressure lingers over the local waters. Dry conditions prevail, with onshore flow today veering northerly overnight into Sunday. Winds then continue to be onshore or northerly through Wednesday, remaining 15kts or less. High coverage of showers Monday, with diminishing chances into Wednesday, as a low pressure system track through the area. A few lightning storms will be possible, mainly over the Gulf Stream. Seas generally 2-4ft, with up to 5ft lingering in the Gulf Stream this evening. A cold front will approach the area Thursday, then pass southward Thursday night, with southwest winds veering northwest Thursday night. Poor boating conditions return, as winds and seas increase into late week. && .AVIATION... (00Z TAFs) Issued at 612 PM EST Sat Feb 22 2025 VFR conds prevail through the TAF period at all sites. Winds becoming light and variable overnight, then NE/E 5-12 KT on Sunday afternoon. No rain is forecast until after 24/06Z. && .PRELIMINARY POINT TEMPS/POPS...
