Area Forecast Discussion National Weather Service Melbourne FL 1024 AM EDT Thu Aug 13 2020

DISCUSSION. Partly cloudy skies were observed across east central FL this morning. Due to the ridge axis extending over the Treasure Coast this morning, the wind flow is quite difference across our forecast area. South of the Cape, winds were from the southeast and already bringing some showers from the waters to Martin and St Lucie counties. Then winds from Osceola/Brevard northward were from the southwest. With this pattern and the development of the sea breeze, showers and thunderstorm are expected to develop along the I-95 corridor from Melbourne southward late this morning and into early afternoon. These will then move inland. Then by mid- afternoon, storms will develop across the interior and will be pushed generally to the northwest towards northern Brevard and Volusia counties. And as these generate outflow boundaries, additional storms will show random movement. Regardless of their slow movement, these will generate strong gusty winds, frequent lightning strikes and moderate to heavy rain. No changes were made to the current forecast.

AVIATION. VFR conditions for rest of the morning. KSUA to KMLB will see SHRA/TSRA development late this morning or early afternoon as sea breeze develops along the east coast and storms develop along I-95 corridor and move inland. Around 18z, inland storm development will start and with a southwest flow from Osceola northward, these storms will generally move to the northeast. Outflow boundaries will also aid in the development of new storms that will then move more randomly. Impacts to terminals will be brief gusty winds and reduced visibilities and frequent lightning strikes. Activity should start to diminish after 13/23z with VFR conditions returning.

MARINE. Winds south of the Cape will be from the south this morning, shifting from the southeast across the nearshore waters as the sea breeze develops later this morning. Winds going over the Cape and to their north, will be generally from the southwest. Storms will reach the waters north of the Cape this afternoon as the move from land. South of the Cape, storm development is expected to remain away from the coast but a few storms could reach the waters late this afternoon as boundary collisions might send them eastward. Outside any storm, winds will be 15 kt or less with seas 1-3 ft.

CLIMATE. As of 10 am, four of our climate sites are on pace to tie or break the daily warm minimums. Min so far Record (year) MCO 78 77 (1903) MLB 78 78 (2019) SFB 78 78 (2010) VRB 77 77 (2010)

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
