.SHORT TERM... (Today through Wednesday) Issued at 128 AM EDT Tue Sep 30 2025
The mid-week period for today and tomorrow will be characterized by a drier couple of days as significant dry air advection occurs via NW flow across the region since South Florida sits on the outer edges of Tropical Storm Imelda`s circulation. Imelda will continue to push eastward today and by tonight will get far enough away to lessen the pressure gradient force and allow for winds to settle down. However, conditions today will remain breezy and gustier as Imelda remains close enough to the Florida Peninsula. Other than that, weather conditions will be mostly tranquil and dry as the abundantly dry air in the mid levels and upper levels of the atmosphere inhibits vertical growth. Some isolated to scattered shallow showers are possible given enough low level moisture presence, but showers are likely to be light and brief.
With less cloud cover and shower coverage, high temperatures will be able to each the low 90s for most areas across South Florida today and tomorrow. Overnight lows Tuesday night are expected in the low to mid 70s.

.LONG TERM... (Wednesday night through Monday) Issued at 128 AM EDT Tue Sep 30 2025
Ensembles are showing a pretty complex pattern setting up for the end of the week and this weekend. Currently, an Omega-Block ridge is set up over the Midwestern United States. Troughs of low pressure will set up on both sides of the blocking setup and an additional shortwave trough develops over the deep south states and the Gulf just south of the ridge axis. This shortwave trough will act to help break down the strong high pressure while also advecting into the South Florida region, but the high pressure ridge will still maintain most of its strength and stretch across most of the eastern United States. As a result, low pressure centers that form via the shortwave trough will essentially become locked in place and not able to move very far. Thus, this would create a setup with continuous energy for showers and thunderstorms to develop. Additionally, South Florida will be in the easterly flow region around the northeast U.S. ridge at least through Saturday, creating a steady stream of deeper moisture advection.
All things considered, this pattern is likely to lead to a wet end to the week and the weekend as well. Potential QPF will depend on several different factors and thus will change quite a bit in the short term, so once details become better defined in the coming days then total rainfall estimates will be outlined. The tail end of the forecast period early next week is highly uncertain at this time, but current projections indicate a continuation of wetter weather.
Daily high temperatures for Thursday and beyond are expected to be in the upper 80s with overnight lows in the low to mid 70s.

.AVIATION... (06Z TAFS) Issued at 128 AM EDT Tue Sep 30 2025
VFR prevails through the period. Breezy northerly/northwesterly winds will prevail through today, with gusts up to 20-25 kts possible during the day. A few isolated showers could be possible but impacts to terminals should remain limited.

.MARINE... Issued at 128 AM EDT Tue Sep 30 2025
A fresh to strong west-northwest breeze continues across the Atlantic waters today as Tropical Storm Imelda remains in the periphery. These winds will decrease to a gentle to moderate breeze on Wednesday. For the Gulf waters, a moderate breeze is expected through Wednesday.
Hazardous winds and seas are expected to continue for the Atlantic waters over the next few days as ongoing swell and breezy winds continue behind Imelda. Seas will range from 7-10 feet through Wednesday and could still remain elevated later in the week. Additionally, scattered showers and thunderstorms are expected each day. A Small Craft Advisory is in place for the Atlantic waters currently through late Wednesday night.

.BEACHES... Issued at 128 AM EDT Tue Sep 30 2025
A high risk for rip currents continues across all Atlantic beaches through the mid-week period as stronger winds and swell occur due to Tropical Storm Imelda passing nearby in the western Atlantic waters. An elevated risk could persist into the end of the week and weekend.
