765 FXUS62 KMLB 180117 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 817 PM EST Sun Nov 17 2024 ...New UPDATE... .KEY MESSAGES... Issued at 305 PM EST Sun Nov 17 2024 - Remaining dry through Tuesday, with rain chances increasing into late Tuesday night and Wednesday. - Gradual warming trend through early this week and then turning much cooler behind a cold front into late week. && .UPDATE... Issued at 815 PM EST Sun Nov 17 2024 Current-Overnight...Surface high pressure across the southeast U.S. will make for a pleasant night. Light onshore flow expected with some marine stratocu streaming onto the coast and points further inland, esp south of the I-4 corridor. Conditions will remain dry with overnight lows in the U50s to around 60F across the interior - normally cooler locations may realize M50s, while closer towards the coast L60s will rule with M-U60s for barrier islands. Aloft, mid- level high pressure remains in control across the FL peninsula. && .PREVIOUS DISCUSSION... Issued at 305 PM EST Sun Nov 17 2024 Current-Tuesday...Surface high pressure over the southeast U.S. will gradually shift southeastward towards the Florida Atlantic coast early this week. Light east-northeast winds gradually veer through the period becoming south-southeast by Tuesday. A thin band of moisture around 850 mb will allow scattered low level cloud cover to continue, especially near the coast. High cloud cover then builds Tuesday ahead of a cold front, and skies begin to become overcast. Afternoon temperatures near 80 on Monday increase a few degrees Tuesday while mostly remaining in the low 80s. Tuesday Night-Wednesday (modified previous)...Some remnant energy/moisture from dissipated TC Sara will shift eastward and across Florida into mid week ahead of an approaching cold front. This will lead to increasing rain chances into Tuesday night, mainly after midnight, and through the day on Wednesday. Some differences continue between the GFS and ECMWF in regards to overall moisture and instability, with the GFS showing lower QPF/CAPE compared to the ECMWF. Have continued to lean on the NBM, keeping the greatest rainfall chances around 60 percent Wednesday. Locally heavy rainfall and a stronger storm or two will be possible on Wednesday, with this activity shifting offshore into Wednesday night as the cold front sweeps through the area. Temperatures will be mild into Tuesday night/early Wednesday morning in the mid to upper 60s, and then increasing cloud cover and rainfall will hold max temps in the upper 70s to low 80s during the day. As the cold front crosses the area, temperatures will fall into the 50s late Wednesday night through early morning Thursday. Thursday-Saturday (previous)...The coldest air of the season so far will move into the area into late week behind the strong cold front, and will be reinforced through early weekend as W/NW flow continues across the area. Highs will generally range from the upper 60s to low 70s over much of the area each day, and overnight lows are forecast to range from the 40s to low 50s each night. Drier air will continue to filter into the area, keeping rain chances out of the forecast. && .MARINE... Issued at 305 PM EST Sun Nov 17 2024 Tonight-Monday...Seas around 4-5 ft tonight continue to improve Monday, subsiding to 2-4 ft. Light and variable winds overnight become east-southeast tomorrow between 5-10 kts. Dry conditions continue. Tuesday-Thursday...High pressure over the local waters is pushed seaward as a cold front moves across the area mid week. Southerly flow around 5-10 kts on Tuesday increases to 10-15 kts Tuesday night as winds veer southwest into Wednesday. Winds continue to increase and veer becoming northwest around 20-25 kts Thursday. Seas between 2-4 ft become poor to hazardous offshore Thursday increasing to 5-7 ft. Coverage of showers and isolated lightning storms returns Tuesday night through Wednesday. && .AVIATION... (00Z TAFs) Issued at 629 PM EST Sun Nov 17 2024 VFR remains forecast through the period.
