Area Forecast Discussion National Weather Service Melbourne FL 309 AM EDT Sun Aug 9 2020

DISCUSSION.

Today-Tonight . Subtropical ridge axis will remain across the area today, with weak low level winds persisting. This will allow sea breeze boundaries on both coasts to push well inland this afternoon. PW values around 1.8-2.0 inches will still be sufficient for scattered storm development along and inland of these boundaries, but greatest coverage should still remain near to northwest of the Interstate 4 corridor from late afternoon through early evening where boundary collisions are most likely. Have rain chances ranging from 20-30 percent along the coast up to 40-50 percent from Osceola County northward through Lake and inland Volusia counties. Main storm threats include frequent lightning, wind gusts up to 40-45 mph and locally heavy rainfall up to 2-3 inches due to slow and erratic storm motion. Temps aloft around -7 to -8C at 500mb may also support some small hail with any stronger storms. Convection will then decrease into the evening with any lingering storms or debris cloud light rainfall diminishing toward or just after midnight.

It will be another hot day, especially inland where highs will again reach the mid 90s. Closer to the coast temps should max out around the upper 80s to low 90s due to the sea breeze. The added humidity will produce heat index values up to 100-105 for much of the area, which is typical for this time of year. Temperatures tonight will then fall into the low to mid 70s late.

Monday-Tuesday . Generally light flow pattern expected to begin the week, as east central Florida is sandwiched between high pressure over the GOMEX and the subtropical ridge over the Atlantic. With weaker flow, both the east and west coast seabreezes will develop and push inland, eventually colliding over the interior. Thus, the highest PoPs will be west of I-95, have PoPs 50-60% there and 35-45% along the coast on Monday. Slightly higher PoPs on Tuesday, with a bit stronger east coast seabreeze. PoPs 60-70% across the interior and 45-55% along the coast Tuesday afternoon. After the initial sea breeze collisions, convection will be largely dominated by boundary interactions through the afternoon and into early evening. Afternoon highs in the mid 90s inland, with low 90s along the coast. Lows in the low to mid 70s.

Wednesday onward . By mid week, the western Atlantic ridge axis will shift slightly north of the area. This would bring stronger onshore flow to the area, perhaps decreasing storm coverage over much of the eastern side of the peninsula, with storms focusing on the western side. However, GFS forecast soundings suggest steering flow remaining light and PWATs 1.8+". The ECMWF also remains quite wet. So, have not deviated much from the inherited forecast, with PoPs 50- 60% through the end of the week. The exception is Wednesday, with PoPs 60-70% as the ridge axis begins to move northward late. Highs in the low 90s mid week onward, with morning lows in the mid 70s, except for upper 70s along the coast as onshore flow strengthens.

AVIATION. Mainly VFR. Isolated showers and storms will initially develop along the coast from late morning to early afternoon, becoming scattered across the interior through the afternoon and early evening hours. Greatest chance for storms will be near to northwest of the I-4 corridor from 20-01Z as sea breeze boundaries move inland and collide across the interior. Will keep VCTS for inland TAF sites for now, but any of this activity will be able to produce tempo IFR/MVFR conditions through this evening.

MARINE. Today-Tonight . Isolated showers and storms will be possible over the Gulf Stream waters this morning, mainly south of Sebastian Inlet, and again into late tonight. Otherwise, boating conditions will remain favorable with light S to E/SE winds, becoming easterly into the afternoon and increasing to 5-10 knots as sea breeze forms and moves inland. Seas will remain around 1-2 feet.

Monday-Thursday . The subtropical ridge axis will remain draped across the area through midweek. This will continue favorable boating conditions, with generally light southerly winds each morning, becoming E/SE at 5-10kts in the afternoon as the seabreeze forms. Then, the ridge axis will shift northward beginning late Wednesday, bringing increased onshore flow. Winds then becoming around 10kts. Seas will remain favorable at 1-2ft, with areas of 3ft well offshore on Thursday.

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