| Area Forecast Discussion National Weather Service Melbourne FL 226pm EDT Sat May 16 2026 ...New KEY MESSAGES,ARINE,Fire Weather .KEY MESSAGES... Issued at 225pm EDT Sat May 16 2026 - High risk for life-threatening rip currents continues at all central Florida Atlantic beaches, and entering the surf is strongly discouraged - Little change in the overall pattern with onshore flow continuing through next week, focusing the highest rain chances across the interior each afternoon - Above normal temperatures to persist through much of next week with heat index values climbing into the low 100s next weekend as moisture increases Issued at 225pm EDT Sat May 16 2026 Rest of Today-Sunday...Following some morning showers along the Treasure Coast, conditions are remaining mostly dry this afternoon. One or two quick showers will appear on radar from time to time, then dissipate just as quick. It is quite warm out as temps climb into the mid 80s to low 90s. Satellite imagery shows plenty of cumulus streaming toward the northwest across the FL Peninsula, as well a hint of a diffuse east coast breeze moving to the west. Late this afternoon and early in the evening, the east and west coast breeze are expected to collide. CAMs suggest a few lightning storms could develop along this collision, particularly in far western Orange/Osceola and southern Lake counties. This forecast update maintains a 20-30% chance of rain/storms over the far interior, accounting for this potential. Rain amounts will stay on the lighter side, but some locations in southern Lake County have a 40-50% of greater than 0.25" (12z HREF probabilities). A strong storm capable of hail and gusty winds is not out of the question, with 500mb temps around -9C and DCAPE above 1000 J/kg. Most activity will fade after sunset with dry conditions returning by midnight for all. Lows settle into the 70s, remaining in the mid/upper 70s along the coast. Sunday is largely a repeat of today, though model guidance suggests a faster inland push of the east coast breeze. As a result, rain chances were lowered in this update for Sunday afternoon. The focus for isolated showers/storms will again be for far interior portions of Okeechobee, Osceola, Orange, and Lake counties. Moreover, a number of models keep the majority of Quantitative Precipitation Forecast from Lake County to the west FL coast. For most, it will be hot and dry with temperatures again reaching the upper 80s to low 90s. At the beaches, a high risk of dangerous rip currents is likely to continue. Entering the surf is strongly discouraged! Monday - Friday Mid/upper level height rises across the eastern/northeastern U.S. are expected through the middle of next week as surface high pressure stays parked over the north-central Atlantic. A front is forecast to drift toward Florida but stall out over the southeast U.S. mid to late week. Model trends have been to keep this front farther north than previously analyzed, indicating that our east-southeasterly wind pattern and above normal temperatures are likely to continue. Diurnally-driven convection will remain focused along the east coast breeze as it develops and moves inland. There is some disagreement as to how quickly higher PW values build over the peninsula late week/next weekend, but the general consensus (for now) is for rain chances to increase areawide next weekend. Coinciding with the increase in moisture would also mean an increase in maximum heat indices. Values could eclipse the 100-degree mark beginning Friday. Marine Issued at 225pm EDT Sat May 16 2026 Now-Wednesday...High pressure to the north of the local waters, drifting farther north and east this week, will maintain a moderate east-southeast breeze through at least Tuesday. Slightly weaker winds return mid to late week. Each afternoon, the east coast breeze is forecast to develop and quickly move inland across the FL peninsula. Isolated showers and lightning storm chances climb on Monday to 30-50%+ south of Sebastian Inlet but largely remain 20-35% through Wednesday. Seas 2-4 ft, climbing briefly to 5 ft Monday evening offshore. Fire Weather Issued at 225pm EDT Sat May 16 2026 An onshore wind will continue for the next several days, generally 10-15 mph (up to 20 mph at the coast). Some gusts to 25 mph cannot be ruled out, particularly at the immediate coast. Isolated onshore- moving showers are possible each morning before the east coast sea breeze moves inland in the afternoon. A couple of lightning storms may occur (20 to 30 percent chance) as the east and west coast breezes collide over the interior. Any lightning strikes could lead to new fire starts. Otherwise, many locations will remain dry with temperatures forecast to range from the upper 80s (coast) to the low 90s (interior).
