747 FXUS62 KMLB 220750 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 350 AM EDT Wed May 22 2024 ...New DISCUSSION, MARINE, FIRE WEATHER... .DISCUSSION... Issued at 349 AM EDT Wed May 22 2024 Today-Thursday...Mid level troughing offshore the southeast U.S. is nudged seaward as ridging extends across the Gulf of Mexico and over Florida. Surface high pressure remains near the eastern seaboard. Ridging in place promotes warming temperatures and drying conditions today and tomorrow. Onshore flow will allow for the inland progression of the east coast seabreeze each afternoon. The best chance for an isolated shower will be in vicinity of Lake Okeechobee where lake and sea breeze boundaries interact. Afternoon temperatures warm into the low 90s across the interior today, remaining in the mid to upper 80s along and east of I-95. Temperatures trend above seasonal values tomorrow, ranging the upper 80s along the coast and nearing the mid 90s across the interior. Friday-Tuesday...Warm and muggy conditions continue to build as moisture returns and a flattening 500mb ridge holds influence over the Florida peninsula. High temperatures further climb through the weekend and into early next week, reaching the upper 90s along and west of I-95 on Sunday. Not much relief on the coast with highs forecast in the low to mid 90s. Heat index values between 97-102 on Friday, increase to 100-107 degrees early next week, nearing Heat Advisory criteria. Take extra precaution if participating in outdoor activities this Memorial Day weekend. Take frequent breaks in shaded or air conditioned areas and stay hydrated.

Mostly dry with shower activity limited to the Treasure Coast waters. Thursday-Sunday...High pressure builds across the local waters, promoting favorable boating conditions through the period. Onshore winds veer south-southwest into Friday, backing along the coast each afternoon as the sea breeze develops. Light winds around 5-10 kts Thursday increase to 10-15 kts into the weekend. Isolated showers and lightning storms will be possible across the Treasure Coast waters Thursday and Friday with coverage expanding to the Brevard waters Saturday and Sunday. && .FIRE WEATHER...
