NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jul 6, 1:41 PM EST, 5 hours 49 minutes earlier.
Area Forecast Discussion National Weather Service Melbourne FL 241 PM EDT WED JUL 6 2016 .DISCUSSION... ...Lower Than Normal Storm Coverage and Hot and Humid Conditions Continuing Through the Upcoming Weekend... Currently/Tonight...East coast sea breeze has been slow to develop so far this afternoon, but will gradually push inland through sunset. Satellite/obs show a weak area of convergence from southern Lake County eastward to northern Brevard County, which the HRRR/WRF models have been keying in on for shower/storm development. However so far only a few pop up showers have formed. Still expect overall low coverage of convection into late afternoon and evening, mainly with sea breeze boundary collisions over the interior, around the I-4 corridor. Drier mid level air will allow any storms to become strong, producing frequent lightning and gusty downburst winds. Previous Discussion... THU-FRI...Axis of the Wrn Atlantic surface ridge will extend across central FL through Thursday. A light wind regime will result with development of E/W coastal sea breeze boundaries as well as local boundaries resulting from strong surface heating. Ridge extending aloft wl inhibit convective potential and the best chance for storm development will be over the inland counties where boundaries interact. POP wl average 20 to 25 percent Thu with a slight increase by Friday due to anticipated weakening of the ridge aloft. Expect warmer than normal temps in the mid 90s with a little relief at the coast due to onshore breeze development. Overnight lows in the mid-upr 70s. SAT-TUE...A weak frontal trough north of the state will drift south and weaken/displace local ridging to the south peninsula during the upcoming weekend. The sfc ridge is shown trying to re- establish over So. central FL early next week. Iso to sct coverage of pop can be expected with best chance over interior counties. due to boundary interactions. Storms should not be particularly strong as notable cooling/drying aloft is not anticipated over the next 5 to 6 days. && .AVIATION...Mainly VFR. Low shower and storm chances continue into this evening, mainly with any boundary collisions favored over the interior late today into this evening. Tempo IFR/MVFR conds will be possible with any of this activity, but due to lower coverage will keep mention limited to VCSH/VCTS. && .MARINE... Tonight-Friday...High pressure extended across the central and southern FL peninsula will keep winds out of the S/SW during the overnight and morning, becoming onshore into the afternoon near the coast as the east coast sea breeze forms and moves inland. Wind speeds will increase to around 15 knots late in the night offshore north of the Cape building seas to 4 feet. Otherwise wind speeds will remain less than 15 knots will seas around 1 to 2 ft near the immediate coast and around 3 ft over the outer waters. Extended...(Previous Discussion) Local wind wave near 1-2 ft at the coast and up to 3 ft offshore and around 3-4 ft in the gulf stream this weekend and early next week. This will be the case north of Cape Canaveral over the outer waters where gradient winds look somewhat stronger. && .PRELIMINARY POINT TEMPS/POPS...
