Area Forecast Discussion National Weather Service Melbourne FL 338 AM EDT Tue Sep 22 2020

DISCUSSION. Today and Tonight . High pressure centered over the Srn Appalachians this morning will drift south, closer to the area over the next 24H. Onshore winds will continue with higher speeds along the coast, albeit lighter than previous days will require a Lake Wind Advisory after daybreak. Notably drier conditions areawide will keep measurable rainfall largely out of the forecast with only isolated light showers from the marine area moving some degree inland during the day. Expect highs in the L-M80s. Onshore flow continues overnight with effects from drying airmass keeping mentionable showers confined to the Atlc waters overnight. Lows wl fall to the relatively pleasant M-U60s by daybreak.

Wednesday-Thursday . With the high pressure ridge over the eastern U.S. now expanded to the Florida peninsula and the pressure gradient eased, onshore winds look to finally decrease to 10-15mph on Wednesday. High pressure influence will also usher in a short period of drier air, with PWATs 1-1.15". Thus, gifting ECFL with a day devoid of mentionable PoPs area-wide. You could almost call it downright pleasant, with partly to mostly cloudy skies and highs in the mid 80s. But, beach and boating conditions will remain hazardous. Overnight lows in the upper 60s to low 70s.

Thursday will be a bit of a transitional day, as the aforementioned high pressure begins to shift eastward into the Atlantic. Onshore winds look to remain around 10-15mph, but will veer SE late Thursday afternoon. As the winds veer SE, moisture will start to return, with PWATs increasing to 1.5-1.75". Therefore, higher rain chances compared to Wednesday, but still lower than the past week or so, with PoPs 20-35%. Highest chances will be along the Treasure Coast. High temperatures warming to near normal in the mid to upper 80s, with overnight lows in the low to mid 70s.

Friday-Monday . Higher PoPs return for the end of the week through the weekend, as high pressure drifts further eastward into the Atlantic. Winds veering SSE on the western periphery of the high pressure. More southerly flow and a surface trough pushing northward through the eastern GOMEX will filter in deeper moisture to ECFL, as PWATs increase to 2+" by Friday afternoon. PoPs 50-65% area-wide Friday through early next week. Highs in the upper 80s to low 90s each afternoon, with morning lows in the low to mid 70s.

AVIATION. VFR conds with some scattering of clouds near FL 035-045 moving onshore during today. Spotty light showers, mainly laong the coast should not pose a sig threat for visual navigation, and the main issue will be breezy conditions of 15 to 25kt by mid-morning esp along the coastal routes and aerodromes.

MARINE. Today and Tonight . Onshore winds around 20 to 25 KT with higher gusts. Wave heights associated with gradient winds and a notable oceanic swell will range 9-11 ft nearshore and 12-13 ft offshore High Surf Advisory with additional beach erosion and minor coastal flooding through this afternoons high tide cycle. Winds will diminish further overnight to around 15 kts, however seas over all the waters will remain well above advisory criteria.

Wednesday-Friday . High pressure influence over the local area and an eased pressure gradient will allow onshore winds to decrease to 10-15kts through the end of the week. E winds Wednesday veering SE on Thursday, then SSE on Friday, as high pressure shifts eastward into the Atlantic. The drier conditions with no mentionable PoPs on Wednesday will not last long, as deeper moisture filters into the area beginning Thursday and PoPs increase to 50-60% by Friday. Although decreasing, seas will remain elevated through much of the week. A Small Craft Advisory is in effect through Wednesday evening due to seas 10-12ft. These values will diminish to 6-8ft late Thursday afternoon, then 4-5ft on Friday.

HYDROLOGY. The Saint Johns River at Astor is forecast to remain in Moderate Flood, before very slowly decreasing. The Saint Johns River above Lake Harney has reached Action Stage, and is forecast to remain steady in Action Stage through this week. The river is forecast to reach Action Stage at Sanford and Deland in the next couple days. Northeast winds and high astronomical tides are combining to prevent normal discharge on the Saint Johns River. Refer to Flood Statements from NWS Melbourne for the river levels and forecasts near Astor and Lake Harney, which will be updated daily while the points remain in flood stage.
