KEY MESSAGES

Updated at 734 AM EDT Tue May 5 2026

- High risk of rip currents persists today for Palm Beach County beaches. There is a moderate risk of rip currents for Broward and Miami Dade beaches.

- Above average temperatures return to the region mid to late this week. Probabilities of heat-related impacts across urban areas during this time frame continue to increase.

SHORT TERM

(Today through Wednesday) Issued at 110 AM EDT Tue May 5 2026

A stationary boundary continues to linger over the Florida Keys early this morning which has allowed for the continuation for a few showers and isolated thunderstorms through the overnight period. This feature is expected to remain in place today, although it will be gradually weakening. More sunshine is expected today than the past couple of days as the boundary fizzles south of the area. While mainly dry conditions should prevail today, a few showers or an isolated thunderstorm will be possible, mainly around the east coast.

On Wednesday, the aforementioned stationary boundary should be sufficiently dissipated which should lead to mainly sunny and quiet prevailing weather. With a lack of synoptic forcing, sea breezes should dominate local surface wind flow, with southeasterly flow prevailing across eastern areas, and west-southwest flow developing across western areas during the early afternoon. Lack of moisture and incoming 500mb ridging (increasing subsidence) should prevent convective development.

High temperatures will reach the upper 80s to lower 90s each day with apparent temperatures in the mid-upper 90s each afternoon.

LONG TERM

(Wednesday night through Monday) Issued at 110 AM EDT Tue May 5 2026

With the aforementioned frontal boundary sufficiently dissipated, high pressure will remain in control through the first half of the long term period. A 500mb ridge slides across the Gulf late Tuesday into Wednesday, leading to the beginning of another warming trend. 500mb temperatures could warm to near daily records between -4 to -5 C. A ridge of this strength aloft will also result in strong subsidence at the surface, which will hinder and suppress rain chances outside of low-capped cumulus afternoon cloud cover and a non-zero chance of a few isolated sprinkles along afternoon boundary collisions where ascent is maximized.

Beginning on Wednesday and persisting into the upcoming weekend, high temperatures across the region are forecast to reach the low to mid 90s with the exception of ocean cooled coastal areas which will max out in the mid to upper 80s. While the mixing down of drier air to the surface will keep apparent temperature and ambient temperature differences lower in separation compared to our standard summer heat, apparent temperatures values in the upper 90s to low 100s are still possible. NWS Prototype Probabilistic HeatRisk depicts a 50-70% probability of Major HeatRisk (Level 3 of 4) on Friday across the east coast metro and increasing to 70-80% on Saturday and Sunday. While these probabilistic values may fluctuate as we remain several days out in time, Major HeatRisk can be impactful to anyone without adequate cooling/hydration as well as health system and industries. Be sure to keep up with the latest forecast updates over the next several days.

An upper level trough will propagate eastward across the Great Lakes region at the end of the work-week as a developing surface low drags its attendant boundary towards the Florida peninsula. This feature will likely stall just north of our forecast area but could still lead to a slight increase in POPs for Saturday and Sunday as a plume of moisture makes its way northward across the area. At this time, POPs remain around 20-30% Saturday and Sunday. Holding steady for now as it's a bit too early to nail down too many details, as it will all be dependent on the progression of the next front.

AVIATION

(12Z TAFS) Issued at 734 AM EDT Tue May 5 2026

VFR conditions for all sites through the period. Light showers across the Gulf Stream have been waning though the morning, leaving mostly clear skies across South Florida. Local sea breezes will dominate the wind regime this afternoon, with about a 10 kt westerly wind for KAPF and about a 10 kt easterly breeze for the eastern sites. Confidence for showers was too low to include in the TAF, but a few spotty showers may be able to develop along the sea breeze convergence over interior portions of South Florida.

MARINE

Issued at 110 AM EDT Tue May 5 2026

Generally improving marine conditions today as east-southeast winds relax and wave heights decrease. Easterly winds around 10-12 kts prevails across local Atlantic waters with wave heights peaking between 3-5 feet. Across local Gulf waters, winds should flip from an easterly direction to a southwesterly direction during the afternoon. Wave heights will remain 1-2 feet.

BEACHES

Issued at 110 AM EDT Tue May 5 2026

A high risk of rip currents continues for Palm Beach County beaches with a moderate risk for Broward and Miami Dade beaches. This threat is expected to gradually decrease by mid-week.
