.SHORT TERM... (Today through Sunday) Issued at 317am EST Sat Nov 8 2025

Ensembles and global model solutions are showing better agreement for the short term synoptic scenario. While most of the E CONUS will be dominated by an active weather pattern, broad high pressure over the western Atlantic will expand into the Florida peninsula through the rest of the weekend. Zonal flow establishes at the mid levels, along with filtering drier air. As the ridge broadens, pressure gradients will relax today and bringing generally light flow at the surface across SoFlo.

Latest model PWATs (Precipitable Waters) show values dropping to near one inch, which will help in keeping basically single-digit POPs and overall benign weather prevailing through Sunday.

Afternoon highs will hit the highest values during the next several days before the anticipated cool down early next week. Expect highs in the upper 80 to around 90 each day.

Long Term
(Sunday night through Friday) Issued at 317am EST Sat Nov 8 2025

Latest ensemble and global solutions show good agreement in bringing a frontal passage across the state starting Monday morning. This will be a dry FROPA, with the main impacts weather-wise being increasing northerly winds and colder air advection.

NBM timing is more consistent with bringing the first colder air intrusion in the Monday late morning-early afternoon time frame, with afternoon highs in the low-mid 70s around the Lake region, and capping around 80 over the southern-most portions of SoFlo.

Northerly winds will reach the 10-15 mph range with higher gusts by the late morning on Monday, with cold air advection intensifying during the evening and overnight hours. Tuesday morning should be the coldest period with morning lows dropping into the upper 30s to low 40s around the Lake region, and mid-upper 40s elsewhere. Locations right along the coast may remain close to 50. For the Tuesday afternoon highs, models are coming a little cooler than previous runs, with low-mid 60s around the Lake region and upper 60s to around 70 elsewhere.

The air mass gradually moderates from Wednesday and through the end of the work week as the west Atlantic ridge returns over the area. Winds veer to a more easterly flow and warms up the air mass. Afternoon highs climb back into the upper 70s to low 80s by Friday.

POPs remain basically in single digits every day of the forecast period with benign weather prevailing.

Marine
Issued at 317am EST Sat Nov 8 2025

Southeast winds around 5-10 knots will gradually shift more south-southwesterly through Sunday ahead of an approaching front. Hazardous marine conditions are expected to quickly develop in the wake of the frontal passage starting Monday morning and continuing through the middle of the work week. Most of South Florida's coastal waters will be affected by the stronger winds. High-end Advisory conditions are possible as early as Monday.

Beaches
Issued at 317am EST Sat Nov 8 2025

A moderate risk of rip currents continues today at all beaches of Palm Beach county.
