AMZ500 Synopsis For Flagler Beach To Jupiter Inlet Out To 60 Nm- 326 Pm Edt Thu Apr 9 2020
Synopsis..The atlantic high pressure ridge axis will remain south of the local atlantic waters, resulting in offshore winds through tonight. A cold front is forecast to quickly cross the area tomorrow, with poor to hazardous conditions developing as winds increase out of the north. The front will stall over south fl, then lift back north over the weekend, as high pressure builds off the u.s. Southeast coast. Boating conditions will briefly improve this weekend, before deteriorating again ahead of the next cold front.
Gulf stream hazards..SEas 3 to 5 feet overnight, with west winds 15 to 20 knots. Then, seas up to 8 ft in the gulf stream Friday afternoon, as northerly winds increase to 20 to 25 knots. The approximate location of the west wall of the gulf stream based on the real time ocean forecast system as of Tuesday, april 7th. 42 nautical miles east of ponce inlet. 29 nautical miles east of port canaveral. 22 nautical miles east of sebastian inlet. 15 nautical miles east of fort pierce inlet. 10 nautical miles east of saint lucie inlet.

Area Forecast Discussion National Weather Service Melbourne FL 336 PM EDT Thu Apr 9 2020

DISCUSSION.

. Near Record Highs Today .

. Period of Unsettled Weather Beginning Early Next Week .

Rest of Today-Tonight . A few showers that developed over Lake County and surrounding areas have dissipated. Shower chances for the remainder of the day look to be less than 15% and, thus, unmentionable. Otherwise, another hot afternoon, with several record and warm minimum temperature record in jeopardy. Thanks to westerly winds ahead of an approaching cold front. See the Climate section for more details. Low clouds will increase overnight tonight as the cold front moves closer to the area. Coupled with continuing westerly flow, this will help to keep temperatures elevated overnight. Lows only falling into the upper 60s to low 70s, which will be 10+ degrees above normal.

Friday . A cold front pushing its way through the Florida panhandle this evening will traverse east central Florida Friday morning. Shower chances will increase from north to south through the morning hours. POPs area-wide will range from 40-50%, with total rain accumulations less than 0.5". There will be a slight chance of thunderstorms in the afternoon south of the I-4 corridor, as buoyancy increases ahead of the front. High temperatures will largely depend on the timing of the frontal passage through an area. Thus, locations north of I-4 could only reach the mid to upper 70s, since they will be the first to see the front move through. Areas to the south will reach the upper 70s to low 80s and even mid 80s along the Treasure Coast, with more time to reach peak daytime heating before the front. Westerly winds around 10 mph will veer to northerly around 15 mph after the front.

Friday Night-Saturday . By sunset Friday night, the cold front will slip south of the forecast area, reaching the southern shores of Lake Okeechobee, continuing its progression across the FL Keys overnight. The entire system will be short lived, with the northerly wind surge of the morning and afternoon quickly diminishing to less than 5 mph prior to midnight. Remnant light showers in the late evening hours, mainly over the Atlantic waters, with a silent 10% PoPs for the Treasure Coast overnight Friday. After sunrise on Saturday, surface high pressure builds in over the coastal Carolinas, dragging slightly drier air mainly across the northern forecast area, with forecast PW of 0.50-0.75" north of a Tampa Bay/Cape Canaveral line, thus limiting rain chances to near zero. For southern areas, however, higher moisture associated with the stalled frontal boundary across the Keys will keep PW above the 1.00" mark, maintaining 20% chance of showers in the vicinity of Lake O Saturday afternoon.

The post frontal cool air advection will be very short lived, restricted to Friday night, where lows dip into the 50s. Values will rebound by Saturday however, to near normal values in the low 80s across the interior, to slightly below in the mid 70s at the coast, with an easy east coast sea breeze development aided by onshore flow. Saturday night lows return to above normal values, nearly 10 degrees warmer than the previous night.

Next Week . Sunday through Wednesday of next week reflects a low confidence forecast, with models diverging on solutions. This weekend, an upper trough over TX shifts northeast, with a sfc low developing over the MS/TN Valleys on Sunday. This feature will subsequently dig a cold front through the Deep South early in the week, but timing as it reaches the FL peninsula still remains to be seen. No major changes to the previous forecast, as the system should be robust enough to provide at least 30-50% PoPs each day through midweek, adding in a slight chance for thunderstorms with sufficient afternoon heating and associated instability. The main uncertainty rides on exact timing of the frontal approach, which currently ranges from late Sunday to late Monday, and its "exit strategy", as the GFS prefers to stall the boundary over FL, leading to several days of showers/storms. Regardless of details, next week looks to be a very unsettled pattern, atypical of a central FL April. Near to above normal highs ranging from the upper 70s to upper 80s, lows in the mid/upper 60s.

AVIATION. VFR conditions through much of the TAF period. Then, IFR CIGS developing after 8Z at all area terminals. Westerly winds veering northerly tomorrow morning, as a cold front passes through the area.

MARINE. Today-Tonight . Generally light, westerly flow will continue through this afternoon. Then, winds will increase later this evening, becoming 15-20 kts through the overnight, as a cold front approaches the area. Seas 2-4 ft nearshore and 3-4 ft offshore, building to 3-5 ft offshore overnight.

Friday . A cold front will move through the area Friday morning. Westerly winds will veer to northerly behind the front and rapidly increase to 20-25 kts. Winds will begin initially in northern zones, before spreading to southern zones only a few hours later. Seas 2-4 ft nearshore and 3-5 ft offshore building to 4-6 ft nearshore and 5- 7 ft offshore, with 8 ft seas in the Gulf Stream.

Saturday-Sunday . Winds and seas will rapidly improve late Friday and early Saturday as the cold front quickly sweeps across the local waters. As high pressure builds across the coastal Carolinas and shifts eastward to the Atlantic, winds veer onshore at 10-15 kts with seas diminishing to 2-4 ft. Sunday, the pressure gradient will tighten as a strong system over the Deep South drags a cold front towards the FL panhandle. Locally, winds veer S/SE, increasing over 20 kts by Sunday afternoon, building seas up to 6 ft in the Gulf Stream waters.

Monday-Tuesday . Hazardous boating conditions will persist early next week as the cold front passes over the local Atlantic waters. Seas will build 4-6 ft nearshore and up to 8 ft in the offshore waters with S winds of 20-25 kts with the potential for gusts up to gale force. A cycle of cautionary statements and SCA will likely be needed over the course of the forecast period.

FIRE WEATHER. Brisk westerly flow will occur today with unseasonably hot conditions. Any new fires will be capable of rapid spread and spotting in any unmanaged situations. Expect high dispersion values as well today. A cold front will move across the area tomorrow, accompanied by increasing rain chances and perhaps an isolated thunderstorm in the southern forecast area. Presence of generally unsettled conditions will allow for mentionable rain chances daily through the weekend.

CLIMATE. Record high temperatures will be approached today.
