AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 401 Am Edt Mon May 20 2024 - Kmia 200616 Wrksyn
Synopsis -
gentle to moderate southwesterly flow this morning will gradually shift to the west-northwest today as a weak front approaches the area and low pressure positions itself northeast of the area. Winds will then shift easterly by the mid-week dominant period as the low shifts away from the area and high pressure builds our north, with speeds remaining relatively light. The threat of Thunderstorms, some of which could be strong, will persist through Tuesday with these storms resulting in periods of locally hazardous winds and seas.
gulf stream hazards: none.

DISCUSSION
Issued at 419 AM EDT Mon May 20 2024

Today-Tonight...Early morning surface analysis has shown a weak cold front sinking into the Florida peninsula, reaching the I-4 corridor.
Widely isolated showers developed overland this morning ahead of the boundary with most convective activity limited to the far offshore Atlantic waters. The front will continue to gradually track southward through the morning, moving south of Lake Okeechobee into the afternoon. Northerly winds behind the front are forecast to increase to around 10 mph, remaining light enough for an east coast sea breeze to develop. Only modest drying is forecast behind the weak front today with model guidance holding on to PWATs around 1.1- 1.4". This lingering moisture could be enough to spark convective activity as the sea breeze moves inland. The current forecast includes a 30 percent chance of showers and storms north of a line from Melbourne to Lake Marian. The greatest coverage of showers and storms lies south of this line (40-50%) where the sea breeze is forecast to interact with the Lake Okeechobee breeze. Surface instability in place could allow for a stronger storm. However, an inversion present above 700mb, warming 500mb temperatures (-8 C), and dry air aloft could all aid in limiting strong updraft growth.
While strong storm development could be limited with some uncertainties, there remains a Marginal Risk for an isolated severe storm across Martin, southern Okeechobee and southern St. Lucie counties where surface instability will be maximized.

Little relief from the heat behind the frontal boundary with afternoon temperatures ranging the mid to upper 80s along and north of the I-4 corridor, climbing into the low 90s southward. A few degrees cooler along the coast. Lingering moisture will promote Heat Index values in the mid to upper 90s across Okeechobee and the Treasure Coast.

Tuesday...Mid level troughing settles across the western Atlantic, extending southwestward across the Florida peninsula. Weak surface troughing sits off the eastern coast of Florida while surface high pressure extends along the eastern seaboard into the Florida panhandle. Locally, light north-northeast flow will support development of an afternoon sea breeze. Once again, modest moisture remains in place to support scattered showers and lightning storms along developing mesoscale boundaries. Temperatures cool two to three degrees compared to Monday, with highs widely ranging the mid to upper 80s. Areas near Lake Okeechobee will be the warmest with highs forecast near 90 degrees.

Wednesday-Sunday...Ridging over the western Gulf of Mexico slides eastward, extending into Florida. A short wave trough moving into the eastern CONUS will then work to flatten ridging in place by late week. The area of anomalous ridging aloft will support drying conditions and warming temperatures at the start of the extended period. Onshore flow continues to promote an east coast sea breeze regime Wednesday and Thursday with only an isolated mention of convection each afternoon. Surface flow begins to veer southerly Thursday night, returning moisture and a mention of scattered precip chances by the weekend. High temperatures in the upper 80s (coast)
to lower 90s (inland) on Wednesday follow a warming trend each day into late week. High temperatures mostly in the mid 90s by Sunday.



MARINE
Issued at 419 AM EDT Mon May 20 2024

Today-Tonight...A weak frontal boundary slides southward across the local waters today. North winds increasing to 10-15 kts behind the front will build seas up to 4-5 ft in the Gulf Steam. Winds veer east along the coast with the development of an east coast sea breeze this afternoon. Isolated to scattered showers and lightning storms are forecast.

Tuesday-Friday...North winds into Tuesday gradually veer onshore into mid week, remaining 7-12 kts. Light winds then veer southward into Friday. Seas up to 5 ft in the Gulf Stream on Tuesday gradually subside, and seas become widely 2-3 ft by Wednesday evening. Scattered to numerous showers and scattered lightning storms are forecast on Tuesday with coverage following a downward trend each following day.



AVIATION
(06Z TAFs)
Issued at 134 AM EDT Mon May 20 2024

Continued mainly VFR across ECFL. Few nuisance showers across the interior initially and may handle with VCSH and a TEMPO group as necessary. Generally a WRLY component of wind thru the night, then gradually transitioning to NW/N around 10 kts into early afternoon ahead of a N/NNE wind surge that will increase speeds to 15-20 kts with higher gusts. We continue to carry VCSH wording early afternoon for many terminals, except VCTS for Treasure Coast terminals around 21Z on Mon, where confidence is higher for convection - closer proximity to a frontal boundary and deeper moisture here.
