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- 421 Pm Edt Mon May 20 2024
Synopsis -
west-northwest winds will be gusty at times as a weak front moves across 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.
the approximate location of the west wall of the gulf stream as of may 18, 2024 at 12 utc - .
7 nautical miles east of fowey rocks. 9 nautical miles east of port everglades. 7 nautical miles southeast of lake worth. 6 nautical miles east southeast of jupiter inlet.

New LONG TERM

SHORT TERM
(Rest of today through Tuesday)
Issued at 122 PM EDT Mon May 20 2024

Portions of southeast Florida could see scattered shower activity once again today as a diffuse front remains draped over the area, with a weak surface low just east of the peninsula. The 12Z sounding today showed ample instability and moisture in the lower levels which could support a few strong thunderstorms mainly along the sea breeze boundary over the East Coast. However, lack of upper level dynamics and weaker shear/lapse rates parameters (as compared to yesterday) will help reduce the chances for severe impacts, with only a few isolated stronger storms potentially producing gusty winds and small hail.

Temperatures will remain above average as westerly/southwesterly winds prevail across the area this afternoon, but lower dew points today compared to the last couple of days should help keep heat index values at or below 100 degrees.

The front will largely have worked its way through the area by Tuesday, and surface flow will generally begin to veer more east- northeast through the day. Rain chances will remain elevated as a trailing shortwave pivots into the area, with at least scattered storms likely igniting along the two sea breezes (with the northeast winds tending to favor southern portions of the area). Temperatures will drop into the upper 80s and lower 90s which while still a few degrees above average, may actually feel pleasant after the mid-May heatwave.

LONG TERM
(Tuesday night through next Sunday)
Issued at 220 PM EDT Mon May 20 2024

By the mid-week, the mid-level shortwave propagates to the east of the region over the western Atlantic waters. The 500mb flow over South Florida will veer to a northerly direction ushering in reinforcing dry air across the region. At the surface, ridging situated over the southeastern United States will allow for relatively light winds across the region. Therefore, with a lack of synoptic support, mesoscale patterns, such as the sea-breeze circulation, will dictate temperatures and the most probable locations for convective initiation and coverage. Typical thunderstorm hazards, such as heavy rainfall and gusty winds, will be possible, but we cannot rule out isolated strong to severe pulse storms that are able to take advantage of the localized maximized ascent along boundary collisions even in the background of a fairly benign pattern.

This benign weather will continue for much of the long-term period as surface ridging remains firmly in place and synoptic features remain to the north of South Florida. With the advection of the surface ridge to the east, easterly surface flow across the region will remain dominant. This will act to feature the hottest temperatures across southwestern Florida for the time being as the Atlantic sea-breeze is able to traverse further inland. High temperatures will range from the upper 80s to low 90s across the east coast of South Florida to temperatures in the low to mid 90s across southwestern Florida. Although heat indices will be less oppressive then the past couple of days, heat safety precautions should still be followed, especially for vulnerable populations.

AVIATION
(18Z TAFS)
Issued at 122 PM EDT Mon May 20 2024

Generally VFR conditions for all TAF sites today, although sub-VFR conditions are possible for East Coast sites this afternoon as SHRA/TSRA develop near the area. W-SW winds 8-12 kts will prevail today, but some East Coast sites could see the sea breeze intruding after 19Z, resulting in a E-SE wind shift. Light and variable winds overnight as conditions improve, with more easterly winds possible tomorrow across much of the area.

MARINE
Issued at 122 PM EDT Mon May 20 2024

Generally benign conditions should prevail across local waters through the period. Scattered to numerous showers and thunderstorms will be expected today and tomorrow as a diffuse front gradually moves across the region, with locally enhanced winds and seas possible in storms particularly over the Atlantic waters. Conditions will improve into the week as high pressure builds over the area.
