AMZ500 Synopsis For Flagler Beach To Jupiter Inlet Out To 60 Nm- 411 Am Edt Sat May 30 2020
Synopsis..The atlantic ridge axis will rebuild across the waters this weekend providing marginally favorable boating conditions. A weakening frontal boundary will cross the waters early Monday, forcing the ridge axis southward. Behind the front, high pressure will build in across the mid-atlantic states, providing a period of freshening onshore flow and poor to hazardous winds and seas early next week. Winds and seas will be locally higher near afternoon and evening showers and storms moving offshore north of port canaveral.
Gulf stream hazards..None. The approximate location of the west wall of the gulf stream based on the real time ocean forecast system as of Thursday, may 28th. 40 nautical miles east of ponce inlet. 28 nautical miles east of port canaveral. 19 nautical miles east of sebastian inlet. 11 nautical miles east of fort pierce inlet. 8 nautical miles east of saint lucie inlet.

Area Forecast Discussion National Weather Service Melbourne FL 448 AM EDT Sat May 30 2020

DISCUSSION. Today and Tonight . An upper wave moving across the southeast during today will act to increase westerly flow locally through the afternoon. The eastern side of the peninsula will be favored for development along the initiating east coast breeze with eastward moving afternoon storms also capable of additional showers and storms into late afternoon and evening producing locally heavy rains.

A ribbon of relatively high moisture around 2 inches along with sufficient instability and boundary interactions will favor scattered to numerous afternoon storms along and east of the I-4 corridor to the I-95 corridor, and eventually the coastal and Atlantic waters from the Space Coast to Volusia County toward evening, with sct coverage southward across the Treasure Coast and Lake Okeechobee.

Main threats will be frequent lightning, downburst winds of 40 to 50 mph, along with torrential rainfall. Showers and storms will persist into evening, especially toward the east coast where steering will bring activity to the coast and adjacent waters past nightfall. Sct coverage in the evening will taper off to isolated by around 11 PM.

Sunday-Tuesday . Mid level trough covering the NE CONUS will shift eastward into the western Atlantic and amplify as additional short wave energy drops SE and offshore into the mean trough position. As this occurs, a mid level ridge with as meridional axis will build east across the SE CONUS and FL. At the surface, a weak surface front will drop southward into NOFL Sun night and through ECFL Mon -Mon night, with high pressure building into Florida behind it Tue.

Expect another convective active day Sun, (POPs 40 coast/50-60 inland). Dearth of surface/steering flow, coupled with expected early initiation will lead to another round of slow moving storms with torrential rainfall and CG lightning the primary concerns, along with brief wet microburst winds. Flow shifts to onshore for Mon-Tue as deeper moisture/higher POPs gets shunted southward. Mode of convection will become more of showers/isolated TS as freshening onshore flow lowers diurnal instability some, and makes for a more diffuse/faster moving ECSB. POPs MON 20-30 north/40-50 south, decreasing to 20 north/30-40 south Tue. Will also see small threat for nocturnal showers materialize, mainly central/south. Max temps U80s coast/L90s inland Sun, L80s coast/M-U80s inland Mon and L80s for all by Lake Co (M80s) Mon. Mins mainly in the 70s, with U60s away from the coast Tue night owing to drier air allowing for more of nocturnal temp drop.

Wednesday-Saturday . There remains significant disparity in the extended range with how the model guidance handles the evolution of the Central American Gyre (CAG) pattern late next week. This in turn impacts the downstream flow pattern across Florida. A piece of vorticity is forecast to eject out of the gyre Wed-Thu, and lift north to NW into the GOMEX. The ECM brings this much closer to FL than either the GFS/CMC, which turn the feature westward. The latter models keep more ridging across FL while the ECM eventually rebuilds the ridge over the state Fri-Sat as a larger portion of the gyre ejects out toward the western GOMEX. The ECM also shows deeper moisture over the area late next week than either GFS/CMC.

Per model consensus, the forecast continues to show POPs (20-40) confined from Brevard south Wed, steadily increasing to 40-50 for Fri-Sat, closer to the wetter ECM. Temps remain a bit below normal for Wed, then near climo from Thu onward.

AVIATION. Sites from ISM to MCO northward may experience sct low cloud decks near FL 010-015 early this morning. VFR conditions until around midday to early afternoon, with showers and storms developing thereafter. Highest coverage and impacts across the interior to east coast near DAB-TTS. Cig and Vsby reductions key on early through mid afternoon for storms that could produce brief MVFR/IFR or Vsby/Sky conditions. Any lingering convection dissipates by late evening with VFR conditions developing overnight.

MARINE. Today-Tonight . South winds early around 10 knots become onshore around 10 knots early afternoon with seas around 3 feet and increasing to 3 to 4 ft by evening. Some lightning storms could initially develop along the coast of Brevard to Volusia, but highest coverage will be inland today with scattered storms along the Volusia to Brevard coasts moving offshore by late afternoon. The main threat with these storms will be dangerous cloud-to- ground lightning strikes and peak wind gusts of 35 to 40 knots.

Sun-Wed . Benign marine conditions (outside of diurnal storms) remain in the forecast for Sun. Deteriorating wind/seas still on tap for early next week as a frontal boundary sags south through the peninsula, with a strengthening pressure ridge building south across the Atlantic Mon-Tue. ENE to E winds will approach 20kt, with season building to 5-7ft, with headlines for SCA beyond 20nmi expected late Mon through Tue. Winds/seas begin to ease as the ridge expands eastward over the western Atlantic, allowing winds to decrease as they veer slightly to SE.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
