Area forecast discussion, Jun 5, 10:38 AM EDT, 4 hours 51 minutes before
Area Forecast Discussion National Weather Service Melbourne FL 1038 AM EDT SUN JUN 5 2016 .DISCUSSION... ...TD3 Forms Near Yucatan... ...Scattered Storms This Afternoon... ...Slight Risk Of Severe Weather and A Few Tornadoes Monday... ...Periods Of Heavy Rain and Nuisance Flooding Possible Monday... Today-Tonight...The morning sounding shows an increase in avbl moisture from Sat, however warming aloft will delay best potential for storms until mid afternoon. The sea breeze along the Space/Treasure coast along with boundary interactions will lead to a scattered coverage over the rest of the area into evening. The main hazards will be local rainfall amounts of 2-3 inches, frequent lighting strikes and gusty winds around 40 mph, hazardous for mariners. Refer to advisories on TD 3 emerging into the Gulf of Mexico just north of the Yucatan this evening and continue moving north overnight. Deep tropical moisture will be pulled up on its east side with the highest precipitable water values (~2.5 inches) likely remaining over the eastern Gulf. MOS and model blend PoPs, which were 40-50 percent, look reasonable for lingering evening convection and overnight showers in increasing moist southerly low level flow associated with the approaching cyclone. Will have to watch for outer rainbands approaching the south late in the night since low level wind shear will be increasing then. && .AVIATION... Increasing moisture will lead to scattered showers and storms during the afternoon. Convective initiation looks to be around 18z in the south, then activity will move/develop northward to the interior and northern terminals about 19-22z. A few storms will produce frequent lightning strikes, gusty winds to 35 knots and quick 2-3 inch downpours as they move north/northeast around 10 knots. && .MARINE... Today-Tonight...Gradually retreating surface high pressure ridge into the Atlantic will cause winds to be southerly with speeds generally 10-15 knots. Seas look 2-3 feet near shore and 3-4 feet in the open Atlantic. Scattered afternoon-evening storms will form quite close to the coast and move north around 10 knots. Some lightning strikes and gusty winds near 35 knots are possible along the intracoastal and nearshore Atlantic waters. The main tightening of the pressure gradient associated with the tropical low lifting north in the eastern Gulf of Mexico looks to hold off until Monday. && .MLB Watches/Warnings/Advisories... FL...None. AM...None. && jp/tes/sms

A FEW STRONG STORMS WITH FREQUENT TO EXCESSIVE LIGHTNING STRIKES, TORRENTIAL DOWNPOURS AND GUSTY WINDS TO AROUND 40 MPH ARE EXPECTED. MOVEMENT SHOULD BE TOWARDS THE NORTH OR NORTHEAST AT 5 TO 10 MPH. .FLOOD IMPACT... A FEW OF THE STRONGER AND SLOWER MOVING STORMS WILL BE CAPABLE OF PRODUCING 2 TO 3 INCHES OF RAINFALL IN A SHORT PERIOD OF TIME, WHICH WOULD CAUSE CONSIDERABLE PONDING OF WATER ON ROADWAYS AND OTHER POORLY DRAINED AREAS. .RIP CURRENT IMPACT... A LINGERING OCEAN SWELL WILL KEEP A MODERATE RIP CURRENT RISK AT AREA BEACHES. THE STRONGEST SEAWARD PULL IS EXPECTED TO BE FROM AROUND MIDDAY THROUGH LATE AFTERNOON DUE TO TIDAL EFFECTS. ONLY SWIM IN THE OCEAN NEAR A LIFEGUARD. .MARINE THUNDERSTORM GUST IMPACT... STORMS FORMING OVER LAND WILL MOVE NORTH TO NORTHEAST AROUND 10 KNOTS THIS AFTERNOON. A FEW COULD PRODUCE GUSTY WINDS TO 35 KNOTS AND FREQUENT LIGHTNING STRIKES OVER THE INTRACOASTAL AND NEARSHORE ATLANTIC WATERS. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
