NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jul 12, 3:00 PM EST, 45 minutes earlier.
Area Forecast Discussion National Weather Service Melbourne FL 400 PM EDT TUE JUL 12 2016 .DISCUSSION... Current/Tonight... Radar/Sat imagery shows the east coast sea breeze bndry pushing well inland south of U.S. Hwy 192...lagging back to just west of I-95 north 192. Active tstorm complex along the east shore of Lake-O with the lake/seabreeze interaction...but elsewhere activity is rather subdued. The prevailing H85-H50 steering flow remains quite weak... AOB 5KTS acrs most of the central peninsula. Bermuda ridge axis extending from the FL Panhandle to NE of the Bahama Bank will maintain a deep, albeit weak, S/SE flow that will focus the bulk of aftn/evng convection over the interior counties. Weak mid lvl vort/upr lvl div will combine with an H70 thermal cap (temps arnd 10C) to impede convective growth thru late aftn. Will need additional mesoscale boundary interaction for any strong tstorm activity to dvlp...namely the west coast sea breeze or outflow boundaries from ongoing convection west of I-75. Potential is there as H50 temps btwn -7C/-8C are generating H70-H50 lapse rates btwn 6.0C/KM along and north of I-4...6.5-7.0C/KM to the south. H85-H30 omega analysis suggests highest storm potential along and west of the Florida Turnpike, but the weak steering flow will limit overall coverage AOB 40pct. Convection may linger past sunset due to the late day initialization, mainly west of a line from Lake George to Lake Marian to Lake-O, but should be done by 02Z. Once again...will need include slgt chc of shras for the Treasure Coast aft 06Z as low lvl onshore flow will maintain the potential for isold shras to form in the wake eddies downwind of the nrn Bahamas. Elsewhere, quiet WX from late evng thru dawn. Srly winds will keep sfc dewpoints in the L/M70s...min temps on the same order. Wed-Thu... Little change in the ongoing WX pattern thru midweek. Upr lvl analysis reveals a relatively weak jet pattern acrs the nrn hemisphere...with a few localized exceptions, H30-H20 winds are largely aob 80KTS with maxes located north of the 40th parallel. Tropical jet is almost non-existent outside of a 40KT jet streak straddling the Hawaiian islands. Bermuda ridge over north FL may meander acrs the FL/GA border from time to time but will remain largely in place as the upr lvl wind pattern will force any short wave trofs acrs the nrn tier states. Position of the ridge will tend to limit daily convective coverage along the coast, highest chances inland where mesoscale boundary interactions will spark sct shra/tsra activity. Prevailing E/SE steering flow will concentrate diurnal convection over the west FL peninsula. PoPs will remain aob 40pct on Wed as a local slug of deep lyr moisture over south FL/nrn Bahamas works its way acrs the state. PoPs aob 30pct on Thu as dry mid lvl air over the central/srn Bahamas pushes into the region. PoPs along the immediate coast will be limited to isold shras/tsras that can dvlp along the seabreeze...Space/Treasure Coasts also may see isold nocturnal shras that form over the Gulf Stream and push onshore in the prevailing onshore flow. The persistent high pressure ridge has provided an extended period of S/SE flow over the lcl Atlc, especially over the Treasure Coast waters. This parallel-to-shore direction is favorable for cold water upwelling over the continental shelf waters. With the high pressure ridge positioned over north FL...S/SE winds should start to cause some upwelling along the Space Coast and maybe even reaching the Volusia county waters. Max temps U80s/L90s along the coast...L/M90s inland. Min temps L/M70s. Fri-Mon...(prev disc) A persistence forecast with only minor shifts in the stagnant pattern as forecast area remains awash in SE-S maritime flow. Continued rather warm especially for inland locations... daytime temps L/M90s except U80s immediate coast. Mins M/U70s. POPs below climo as embedded east coast sea breeze ushers quickly inland. && .AVIATION...Thru 13/18Z. Sfc Winds: Thru 13/02Z...coastal sites E/SE 9-13KTS...interior sites S/SE 6-10kts.

ISOLATED LIGHTNING STORMS WILL DEVELOP AS THE EAST COAST SEA BREEZE MOVES INLAND ACROSS THE TREASURE COAST THROUGH EARLY AFTERNOON. STORMS WILL CONTINUE TO DEVELOP TOWARD THE NORTH AND WEST THROUGH THE AFTERNOON, BECOMING SCATTERED IN COVERAGE AND FOCUS ON INTERIOR AREAS FROM OKEECHOBEE NORTHWARD TO LAKE COUNTY. THE MAIN THREATS FROM STORMS TODAY WILL BE DANGEROUS CLOUD TO GROUND LIGHTNING. A FEW STORMS RESULTING FROM BOUNDARY COLLISIONS MAY PRODUCE FREQUENT CLOUD TO GROUND LIGHTNING, SMALL HAIL, AND WIND GUSTS UP TO 50 MPH.

ABOVE NORMAL TEMPERATURES AND HIGH HUMIDITY LEVELS WILL COMBINE TO PRODUCE PEAK HEAT INDEX VALUES AROUND 105 THIS AFTERNOON GENERALLY ACROSS AREAS INLAND FROM THE COAST. IF YOU WILL BE OUTDOORS, DRINK PLENTY OF WATER AND TAKE FREQUENT BREAKS OUT OF THE SUN. .MARINE THUNDERSTORM GUST IMPACT... LIGHTNING STORMS ARE EXPECTED TO DEVELOP OVER LAND AND AFFECT MAINLY INLAND LAKES, HOWEVER, A FEW WIND GUSTS FROM THUNDERSTORM OUTFLOWS ARE POSSIBLE ALONG THE TREASURE COAST LATE THIS MORNING AND EARLY THIS AFTERNOON AS THE SEA BREEZE DEVELOPS AND MOVES INLAND. A FEW LIGHTNING STORMS MAY PRODUCE WIND GUSTS AROUND 35 KNOTS AND FREQUENT LIGHTNING STRIKES THIS AFTERNOON AND EARLY EVENING. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY. SCATTERED TO ISOLATED STORMS REMAIN IN THE FORECAST THIS UPCOMING WEEK, MAINLY OVER INTERIOR SECTIONS. ANY SUMMER STORMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING LOCAL HEAVY RAINFALL, STRONG GUSTY WINDS AND FREQUENT LIGHTNING STRIKES. .SPOTTER INFORMATION STATEMENT...
