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- 1001 Am Edt Tue May 21 2024
Synopsis -
winds will gradually shift to a north to northeasterly direction today as a weak surface low shifts away from the area and high pressure builds to our north with speeds remaining relatively light. The threat of Thunderstorms, some of which could be strong, will persist through today with these storms resulting in periods of locally hazardous winds and seas.
gulf stream hazards: none

New AVIATION

SHORT TERM
(Today through Wednesday)
Issued at 247 AM EDT Tue May 21 2024

Mesoanalysis this morning indicates a diffuse frontal boundary oriented east to west across the area, best evident by a subtle dew point gradient north to south across the region as well as a wind shift to a northeasterly direction to the north of the frontolytic boundary. Taking a peek aloft, a shortwave remains just to the northeast of our region gradually shifting eastward into the western Atlantic waters. 500mb flow on the posterior side of this feature will usher in northwesterly mid-level flow across the region today. The combination of stronger easterly/northeasterly flow at the surface and north westerly flow aloft will act to focus sea-breeze driven convection southward across the region, with the greatest chances of precipitation across our southern areas (particularly Miami-Dade County and Mainland Monroe) during the afternoon hours. Storm evolution will once again be in the form of multicellular clusters propagating along the edges of cold pools, feeding off of ample CAPE profiles. Mesoscale models indicate the potential of an SBCAPE gradient in conjunction with the inward propagating Atlantic sea-breeze, enhanced ascent along this boundary will lead to convective initiation during the afternoon hours. Although overall severe parameters do not appear to be conducive, there will still be the potential for an isolated strong to severe storm or two. DCAPE values of 1000-1200+ J/kg support the potential of wet microbursts with the strongest convective updrafts. In addition, Although the axis of the shortwave has propagated offshore of the CONUS, South Florida will remain on the periphery of the cold pool aloft with 500mb temperatures still in the -7C to -8C range. This could allow for some small hail to fall if a taller core develops. In addition, although antecedent conditions remain fairly dry across the southern portions of the east coast metro area, cannot rule out some pockets of minor urban flooding in vulnerable low lying locations given the relatively light 500mb flow. High temperatures will reach the upper 80s to low 90s across the region, with the warmest temperatures being realized across southwestern Florida.

With the shortwave continuing to propagate to the east on Wednesday, 500mb flow will veer more to a northerly direction in nature. Combined with northeasterly surface flow prevailing, sea-breeze circulations will favor convective initiation across the southern inland portions of our area. As the shortwave continues to propagate away, 500mb temperatures will continue to warm with 500mb temps in the -5C to -6C range possible. This will keep the majority of thunderstorm activity in the garden variety form, although localized ascent along boundary collisions could still support the potential of an isolated strong to severe wet microburst if a storm pulses up and collapses in a quick fashion.

LONG TERM
(Wednesday night through Monday)
Issued at 247 AM EDT Tue May 21 2024

During the mid-week period, the mid-level shortwave will remain situated over the western Atlantic waters to the east of the Bahamas. A mid-level ridge will also develop and remain centered over the western Gulf of Mexico during this time frame.
Between these two synoptic features, South Florida will remain in a light northerly 500mb flow regime with a lack of synoptic forcing across the area with the subtropical jet located well to the north of our 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 the aforementioned 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 still 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.

The mesoscale driven weather pattern 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 than the past couple of days, heat safety precautions should still be followed, especially for vulnerable populations.

AVIATION
(12Z TAFS)
Issued at 653 AM EDT Tue May 21 2024

Mainly VFR conditions will prevail through the period. Light and variable winds early this morning will increase out of the east by early afternoon to around 10 kts. Scattered showers and storms will develop near the east coast terminals as the afternoon progresses. Periods of MVFR or IFR will be possible in and around storms. At KAPF, winds will increase out of the west in the afternoon as a Gulf breeze develops.

MARINE
Issued at 247 AM EDT Tue May 21 2024

Generally benign conditions should prevail across local waters throughout the period. Locally enhanced winds and seas will be possible in and around shower and thunderstorm activity across our area waters.

BEACHES
Issued at 247 AM EDT Tue May 21 2024

With onshore wind flow returning to the east coast of South Florida, a gradual increase in rip current risks will materialize across the east coast through the remainder of the work-week. A moderate risk of rip currents is forecast for Palm Beach County beaches today.
