AMZ500 Synopsis For Flagler Beach To Jupiter Inlet Out To 60 Nm- 405 Am Edt Tue Jul 7 2020
Synopsis..Weak low pressure over the southeast u.s. Combined with the atlantic ridge axis across south florida will produce a southwest to west wind flow the remainder of the week. A delayed sea breeze will develop each afternoon but remain pinned near the coast. Deep moisture will continue across east central florida, resulting in high coverage for showers and Thunderstorms pushing offshore the mainland and across the intracoastal and nearshore atlantic waters each afternoon.
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 Sunday, july 5th. 44 nautical miles east of ponce inlet. 33 nautical miles east of port canaveral. 24 nautical miles east of sebastian inlet. 17 nautical miles east of fort pierce inlet. 10 nautical miles east of saint lucie inlet.

DISCUSSION.

. Above Normal Rain Chances Continue Through Much of the Week . . Storms Pushing Offshore Will Remain a Threat to Boaters .

Today-Tonight . Ridge axis of high pressure over the west Atlantic will exist near to just south of Lake Okeechobee today, with low level winds remaining out of the SW over much of the area. The prevailing offshore flow combined with elevated PW values of 1.9-2.0 inches will continue to generate scattered to numerous showers over the interior by early afternoon that will shift eastward toward the coast and offshore through late afternoon into early evening. Have kept rain chances around 60-70 percent across the region for this expected above normal convective coverage.

A few stronger storms will continue to be possible, especially with storm/outflow boundary interactions that occur with the east coast sea breeze, which has a better chance to develop and move slowly inland across Brevard County and the Treasure Coast into early-mid afternoon. Main storm threats will continue to include frequent lightning strikes and strong wind gusts up to 45-55 mph. In addition, increased flooding concerns of roadways and poor drainage areas will exist for locations that have already seen repeated rounds of heavy rainfall over the past few days, especially along the coast, as locally heavy rainfall of 2-4 inches will again be possible this afternoon.

Skies will start off mostly to partly sunny with highs able to reach the low 90s across much of the area before storms and cloud cover increase across the region. Cloud cover will then gradually decrease overnight, with lows in the low to mid 70s. While rain chances will have largely ended across the area by midnight, a few showers may still be able to reach Lake County and I-4 corridor before they weaken as they push eastward late in the night.

Wed-Thu . Weak low pressure will be over South Carolina Wed morning and will move northeast reaching the North Carlina coast Thu. The Atlc subtropical ridge axis will remain near or south of Lake Okeechobee through mid-week. These two features will maintain a west to southwest (offshore) flow pattern across EC FL. This will at least delay the east coast sea breeze formation and may prevent a sea breeze altogether along the Volusia coast. But from the Cape southward, the sea breeze will develop each afternoon but remain pinned near the coast. Deep moisture (PWATs ~2 inches) will remain across northern sections Wed but a little drier air should filter in across the south. So have drawn 60-70 PoPs across north/central sections and 40-50 PoPs southern 1/3. On Thu, the deep moisture across the north should push east of the area but trailing deeper moisture across the south. So have drawn 40 PoP across the north and 50-60 PoP south of Orlando.

Temperatures aloft look rather warm with -5C to -6C at 500 mb and unimpressive lapse rates. Still, storm coverage will remain at or above normal with a few strong storms possible each day, especially toward the east coast later in the afternoon as storms and outflow boundaries interact with the east coast sea breeze. Lightning strikes will be the primary threat along with gusty winds and heavy rainfall. Highs will reach the low 90s with mid 90s where cloud cover and precip coverage is lower.

Fri-Mon . Models continue to show surface low shifting N/NE along the eastern U.S. seaboard this period. A lingering frontal boundary will be left in the wake of this low, remaining nearly stationary north of Florida. This feature combined with a reinforcing trough across the eastern U.S. will keep ridge axis south of the area and a continued offshore (W/SW) flow pattern across the region.

Deeper moisture will gradually build back across central Florida during this timeframe, with higher rain chances of 60-70 percent expected each day, as scattered to numerous afternoon storms continue to develop and push eastward across the area and offshore into early evening. An increase in W/SW low level winds through late week and into the weekend may be enough to limit or prevent east coast sea breeze development, with highs reaching the low to mid 90s each day before convection and cloud cover increases across the area.

AVIATION. VFR conditions expected through the morning, with scattered to numerous showers and storms then producing tempo IFR/MVFR conditions and gusty winds into the afternoon and early evening as they shift eastward across the area and offshore. Rain chances will mostly come to an end by midnight, with only a slight chance for showers near to northwest of the I-4 corridor overnight.

MARINE. Today-Tonight . Subtropical ridge axis near to just south of Lake Okeechobee will keep winds out of the S/SW this morning, becoming S/SE into the afternoon as the east coast sea breeze forms. Winds will generally remain below 15 knots with seas ranging from 1-3 feet.

However, scattered to numerous offshore moving storms from the mid afternoon through early evening timeframe will continue to generate strong gusty winds and brief increases in wave heights. Boaters should be prepared to seek safe harbor.

Wed-Sat . Ridge axis near or south of Lake Okeechobee will remain in place with W/SW winds becoming SE in the late afternoon near the coast as the east coast sea breeze develops. There is a chance the sea breeze will not form along the Volusia coast some days if the offshore flow is too strong. The threshold is roughly 15 knots at 850 mb. Wind speeds forecast to remain 15 knots or less with seas 1-3 feet, increasing to 4 feet offshore Fri night/Sat.

Main threat to boaters will continue to be scattered to numerous offshore moving storms producing frequent lightning strikes and gusty winds, mainly from mid afternoon through early evening each day.
