Long Term
(Sunday night through Friday) Issued at 252am EDT Sat July 20 2024

High pressure is expected to prevail through the end of the weekend heading into early next week. The aforementioned plume of Saharan dust will washout over the area and continue to head northward as deep tropical moisture advects across the region through the day on Monday with PWATs (Precipitable Waters) spiking up to the 2.2 to 2.4 inch range. This will help to enhance shower and thunderstorm activity especially on Sunday night into Monday morning as this pushes through. With lack of mid to upper level support, strong thunderstorm development chances will remain low and the main concern will be the potential for heavy downpours and localized flooding. With easterly to southeasterly flow expected to continue through the majority of the long term period, greatest shower and thunderstorm coverage can be expected over interior and southwest portions of the area.

A Tropical Upper Tropospheric Trough (TUTT) will slowly approach South Florida through the period. At this time, this feature remains northeast of the Bahamas and a fair amount of disagreement remains regarding the timing of it. This feature could provide extra synoptic support for showers and thunderstorms towards the end of the upcoming week. While the exact details still remain uncertain, strong thunderstorm development will remain possible with gusty winds and heavy downpours along with the potential of localized flooding as this TUTT approaches and moves through the region. The latest forecast takes a blend of the forecast models and increases the chances of showers and thunderstorms for the middle to end of the week. This will continue to be monitored as the week progresses. High temperatures will generally remain in the lower to mid 90s each day through middle to end of the week.

Temperatures through the long term will remain quite warm with highs in the lower to middle 90s. Heat indices will reach the 100-110 degree range each afternoon and Heat Advisories are highly likely.

Marine
Issued at 252am EDT Sat July 20 2024

East to southeast winds will continue over South Florida waters through this weekend and into next week due to the high pressure over the Western Atlantic waters remaining nearly stationary. Wind speeds will generally be gentle to moderate each day. Seas of 1-3 ft in the Atlantic and 2 ft or less in the Gulf. Scattered thunderstorms are expected each day through the next week which may result in locally higher winds and seas.

Beaches
Issued at 252am EDT Sat July 20 2024

Increasing east to southeast flow this weekend will result in an elevated rip current risk for the Atlantic beaches.
