SHORT TERM
(Today through Wednesday)
Issued at 113 AM EDT Tue May 20 2025
Mid-level water vapor imagery early this morning courtesy of GOES-19 depicts a wide expanse of mid to upper level ridging established over South Florida, the southern Gulf, and the western Caribbean Sea. 5z ACARS data from SoFlo airports and the earlier 00z MFL upper air sounding depict a continued subsidence inversion at 850mb with very dry air established above that layer throughout the rest of the vertical column. At the surface, a ridge of surface high pressure will remain established across the western Atlantic waters with the periphery of this ridge being established across South Florida.
Surface flow will begin to veer to more of a light south-southeast component; however the afternoon weather regime will once again be dictated in the mesoscale domain as sea-breeze circulations develop and push inland, before colliding late in the day over the Everglades. The continued subsidence inversion and dry air aloft will keep low level cloud cover fairly shallow in nature. A more southerly surface flow component, ample surface humidity, and ample sunshine will result in quite the toasty day across the region. High temperatures today will range from the upper 80s to low 90s along the immediate coast with temperatures in the mid 90s possible across metro suburbs. Away from the cooling ocean breeze behind inland propagating sea-breezes, temperatures across inland southwestern Florida and Lake Okeechobee could reach the upper 90s during the afternoon hours. Heat indices will reach the upper 90s to low 100s across the region this afternoon, just below Heat Advisory thresholds. However, although conditions will just below these thresholds, the heat risk for most of South Florida tomorrow will be in the moderate range with even a few locales in the major range.
Individuals who will be outdoors today and tomorrow for an extended amount of time should ensure that they take heat safety precautions.
Rain chances will remain minimal today as stout subsidence and dry air in the vertical column keep quiet weather conditions prevailing.
Cannot rule out a few brief showers popping up along boundary collisions across inland locations late in the afternoon hours but overall the dry and hot pattern will persist.
Much of the same on Wednesday as surface flow veers to a light southwesterly component as the surface ridging begins to wane over the region. This subtle wind shift will focus the hottest afternoon temperatures on Wednesday across inland southeastern Florida.
Temperatures across the east coast metro will range from the low 90s along the coast to temperatures in the middle 90s across inland suburbs. A corridor of upper 90s is forecast by several deterministic and ensemble model members just to the west of the metro, away from the moderating oceanic influence of the Atlantic waters and a pinned Atlantic sea-breeze. The mesoscale CAMS (HRRR, RAFS, and RAP) hint at the potential of a few isolated showers popping up on the previously mentioned pinned Atlantic sea-breeze during the afternoon to early evening hours of Wednesday. In addition, Saturated Low- level boundary layer relative humidity values could result in patchy dense fog late overnight Wednesday into the daybreak hours on Thursday near Lake Okeechobee as clear skies, light winds, and the nocturnal inversion provide favorable conditions for fog development.
LONG TERM
(Wednesday night through Monday)
Issued at 113 AM EDT Tue May 20 2025
After a prolonged period of stout mid-level ridging and anhydrous conditions, a pattern change is indeed on the horizon for South Florida. The arrival of a mid-level trough across the northeastern United States on Wednesday night into Thursday will allow for a surface low to accelerate northeastward on the leeward side of the Appalachian mountains. The aforementioned surface low will drag an attendant surface boundary southeastwards across the Gulf and Florida Peninsula during the day on Thursday. An envelope of deeper atmospheric moisture will advect into the region in tandem with the front, depicted on the GFS and European models with precipitable water values in the 1.5 to 2.0 inch range. At the same time, mid- level flow will veer to a westerly direction and enhance as South Florida will be situated underneath the base of the mid-level trough. This upper-level flow regime will persist on Thursday and Friday and in tandem with light southwesterly surface flow, focus any afternoon rain chances across the eastern half of the region as the aforementioned background southwesterly flow interacts with a pinned Atlantic sea-breeze. 500mb temperatures will cool gradually during this period, steepening lapse rates further on Friday afternoon. Residual mid-level dry air in the vertical column and these cooler temperatures aloft could actually led to an isolated strong to marginally severe storm or two along the pinned Atlantic sea-breeze on Thursday and Friday afternoon/evening. Small to marginally severe hail (lower freezing level) and strong to severe wind gusts (DCAPE >1000 J/kg) is possible in tandem with frequent lightning with storms that develop directly on the sea-breeze. Of course, this potential threat will be contingent on how far the mid- level trough digs across the region. A more northerly trajectory of the aforementioned dynamics would greatly reduce any threat of seeing an isolated strong to marginally severe storm.
By the weekend, the front will become frontolytic in nature with mid- level flow lessening greatly across the region. However the residual moisture associated with the front will remain in place across the region. This will allow for both the Atlantic and Gulf sea-breezes to propagate inland with the greatest chance for afternoon showers and storms across inland locales. 500mb temperatures will still be cool enough to steepen lapse rates and usher in the potential of a few strong afternoon storms. Heavy rainfall, locally gusty winds, and frequent lightning is possible with storms.
Throughout the extended period, high temperatures will be a few degrees cooler in large part due to cloud cover. Sharp fluctuations and gradients in afternoon temperature are indeed possible as shower and thunderstorm activity will act to knock down temperatures from their diurnal peaks.
AVIATION
(06Z TAFS)
Issued at 113 AM EDT Tue May 20 2025
VFR conditions will prevail throughout the forecast period. Light and variable winds overnight will increase out of the SSE during the early afternoon hours and will range between 10 to 15 kts into this evening. At KAPF, winds will increase out of the SW this afternoon as a Gulf breeze develops.
MARINE
Issued at 113 AM EDT Tue May 20 2025
Mostly benign marine conditions persist through the remainder of the work week with light winds and seas 2 ft or less. A few late day showers are possible near the Lake Okeechobee and Everglades areas each afternoon.
