| Area Forecast Discussion National Weather Service Miami FL 601am EST Thu Nov 6 2025 .SHORT TERM... (Today through Friday) Issued at 125am EST Thu Nov 6 2025 A southern stream shortwave, positioned over a mid-level low in the central Gulf this morning, will move ENE through the Gulf and North Florida through today. As it departs, the mid level low will open up into a trough and weaken through the day. Overnight, another southern stream wave will move into the western Gulf and slightly strengthen the trough again as they interact. At the same time, the northern stream pattern will be amplifying and influence the mid-level pattern enough to move the trough along to the east with the upper wave. This will result in a mid/upper level frontal system moving across the state on Friday. At the surface, the eastern CONUS ridge will yield easterly flow locally during the day today. By tomorrow, the ridge will have shifted east enough to veer flow more southerly. Essentially, all of the above will act to increase deep level moisture over the coming days. The upper level waves may also bring some weak upper level forcing to the region while forcing at the low-levels will remain mostly at the coastal interface today, and then on the leading edge of the more tropical airmass on Friday. There aren't really mentionable rain chances today, though a stray shower may impact locations along the immediate east coast today before quickly dissipating as they move inland. Friday will probably be the wettest of the upcoming days, and even then rain chances only climb as high as 20-40% and remain confined to mainly the eastern half of south Florida. Highs will remain in the mid 80s with morning lows in the low 70s along the coasts and upper 60s across the interior. Long Term (Friday night through Wednesday) Issued at 125am EST Thu Nov 6 2025 The weekend will feature dry air aloft in the wake of Friday's mid/upper frontal system. At the surface, flow will gradually veer from southerly to southwesterly as the ridge axis continues to shift. A combination of the low-level moisture and a weak seabreeze circulation will keep about a 20% chance of a stray shower each afternoon. Highs will warm into the upper 80s to near 90 degrees, with heat indices into the middle 90s. Early next week, attention turns to our next cold front. There's still quite a bit of disagreement between the global ensembles regarding the progressiveness of the longwave pattern, and also just how far south the core of the shortwave makes it into the eastern CONUS. Regardless, it appears as though we will get a frontal passage at some point on Monday or as late as Monday evening. It also appears that no matter how the longwave pattern evolves, little to no rainfall is expected with the frontal passage. So really, the main sensible weather impacts we'll experience, that depend on the evolution, are related to temperatures. As far as overnight lows go, their bottom end won't vary too much based on the amplitude of the low, but just how quickly the cool air arrives (i.e. Monday night or Tuesday night) will depend on how progressive the frontal system is. The amplitude of the system will dictate whether afternoon highs or lows will be warmer or colder than what is advertised in the deterministic forecast. At this time it looks like it could go either way with about a 30% chance of being colder or warmer than what is being advertised right now. Marine Issued at 125am EST Thu Nov 6 2025 Easterly winds around 10 knots or less will prevail through the first part of the weekend before turning southerly late this weekend ahead of an approaching front. Upon frontal passage early next week, hazardous marine conditions will overspread our Gulf and Atlantic waters. High-end Advisory conditions are possible as early as Monday. Hydrology Issued at 125am EST Thu Nov 6 2025 We'll be coming off the peak of this King Tide cycle today, with water levels expected to reach Minor flood stage once again along the east coast. At this time, the probability of Moderate (or advisory) level flooding is too low to warrant an Advisory, but the highest water level anomalies would be expected across the Palm Beach county coast.
