KEY MESSAGES

Updated at 530 PM EST Tue Nov 18 2025

- Mainly dry and pleasant conditions will remain in place across South Florida through the work-week. - Patchy fog is possible early this morning over interior portions of South FL.

- Above normal temperatures may return to portions of South Florida towards the middle and the end of the week as mid level ridging strengthens over the region.

UPDATE

Issued at 1209 PM EST Tue Nov 18 2025

Current forecast remains on track with tranquil weather persisting. Dry and comfortable conditions expected through the short term and likely beyond. High temperatures today expected in the low to mid 80s.

SHORT TERM

(Today through Wednesday) Issued at 1231 AM EST Tue Nov 18 2025

Zonal flow remains established over South Florida early this morning as surface high pressure remains across the Southeast CONUS. A weakening frontal boundary is draped across the area leading to very light surface wind flow. As this weak boundary continues to dissipate over the area, surface flow will increase out of the northeast this afternoon while an upper level ridge becomes established over the Gulf through mid-week. With an abundance of dry air in place throughout most of the atmospheric column, (PWAT values hovering between 0.7 and 0.9 inches), the sensible weather across South Florida will remain dry and pleasant throughout the next two days...and likely even into next week. Overall, high pressure and dry air dominate the weather regime making way for many sunny days this week, leaving me with not much to discuss.

High temperatures will reach the low to mid 80s today and tomorrow. Some parts of interior South Florida may reach the upper 80s.

LONG TERM

(Wednesday night through Monday) Issued at 1231 AM EST Tue Nov 18 2025

Fairly benign and quiet weather prevails through the long term forecast period. Mid-level ridging builds across the Gulf by late Wednesday which should keep South Florida firmly in an east- northeast regime for the Thursday-Saturday timeframe. With an abundance of dry air remaining in place across the mid to upper levels, mainly dry conditions will prevail through the remainder of the week. A few short lived showers may be possible near the east coast regions, however POPs remain less than 10%. As the mid level ridge strengthens across the Gulf region, easterly to northeasterly surface flow will increase as the pressure gradient tightens leading to breezy conditions over the local Atlantic waters and along the southeast coastline.

Through the end of the week and first half of the weekend, high pressure remains in control of the sensible weather across South Florida with PWATs remaining around 1 inch or less. This should continue to support dry and mainly sunny conditions through at least the first half of the weekend. Our next frontal boundary could approach the area on Sunday leading to wind shift from the south- southwest. Latest guidance is not too excited with this boundary as it will be weakening on final approach, although moisture will begin increasing with PWATs potentially breaching 1.2-1.3 inches. This would take us back to just about average moisture for November which really isn't anything to get excited over. While this frontal passage is still about a week out and will be monitored, at this time it appears mainly dry and mainly sunny conditions will continue to prevail through the late weekend-early next week timeframe as well.

High temperatures Wednesday through the weekend will generally range from the lower 80s across the east coast metro areas to the mid to upper 80s across interior portions of Southwest Florida.

AVIATION

(00Z TAFS) Issued at 530 PM EST Tue Nov 18 2025

VFR prevails through the period. Mainly east-northeast winds through this evening around 5-10 kts will become light and variable tonight. For tomorrow, winds increase again out of the NE at 5-10 kts with KAPF seeing a wind shift to the NW in the afternoon.

MARINE

Issued at 1231 AM EST Tue Nov 18 2025

A gentle to moderate northeasterly breeze will prevail across local waters today and tomorrow. Wave heights should remain 3 feet or less.
