| Area Forecast Discussion National Weather Service Miami FL 247pm EDT Fri Oct 2 2026 ...New .KEY MESSAGES... Updated at 230pm EDT Fri Oct 2 2026 - A high risk of rip currents remains in place across the Atlantic Coast beaches through Saturday evening. - Scattered showers and thunderstorms will remain possible each day through the upcoming weekend. The highest chances will remain during the afternoon and evening hours over the interior as well as Southwest Florida. - High temperatures will climb back into the low 90s in many areas of South Florida, along with Heat Index values in the low-mid 100s each day through the weekend. Issued at 230pm EDT Fri Oct 2 2026 As a mid level low continues to pull further away from the region into the Southwestern Gulf and the Bay of Campeche, mid level ridging continues to slide into the region from the western Atlantic. At the surface, strong high pressure centered off to the northeast is keeping the pressure gradient across South Florida rather tight and is responsible for the breezy and gusty east southeasterly wind flow across the region. The latest 18z ACARS data shows some mid level dry air working into the region this afternoon as the mid level ridge moves closer to South Florida. While this is keeping coverage of showers and storms across the region rather low this afternoon, some additional convective development will be possible mainly across the interior as well as Southwest Florida where sea breeze boundaries collide. With mid level heigheights increasing along with mid level dry air acting as a capping mechanism, chances for strong thunderstorm development will remain extremely limited this afternoon into this evening. Any convection that does develop will gradually diminsh later this evening, leaving mostly dry conditions in place for most of South Florida during the overnight hours. Low temperatures tonight will generally range from the lower to mid 70s across Southwest Florida to the upper 70s across the east coast metro areas. .SHORT TERM... (Today through Saturday) Issued at 404am EDT Fri Oct 2 2026 Guidance consensus, including ensembles, show mid-level ridging gradually drifting southward across the SE CONUS and into northern FL today as a trough/low complex develops around the mid-west states. Meanwhile, the ridge axis of the Atlantic high slides further west and lingers north of the area, keeping a generally E/SE wind regime in place through the short term. Latest satellite water vapor imagery shows some pockets of mid-level drier air filtering into the area, which will act as temporary caps to convective activity today. NBM POPs drop into the 20-50% range for much of SoFlo today, then gradually increasing into the 40-60% range by Saturday. PWATs (Precipitable Waters) should remain just above 2", while 500 mb temps warm up a little to around -5C and SBCAPE will remain in the 1.5K-2K j/kg range. This will keep potential for strong to severe cells rather limited, but can't rule out a few strong or an isolated severe storm, especially over interior/western SoFlo. Greatest threat will be localized flooding with the heaviest downpours. Cloud coverage should break during the morning hours and allow for some additional heating to push afternoon highs back into the U80s- L90s today and on Saturday. Heat index values may also climb back into the low-mid 100s across much of the area. Long Term (Saturday night through Thursday) Issued at 404am EDT Fri Oct 2 2026 Long range guidance depicts a summer-like pattern prevailing on Sunday with the Atlantic high ridge axis lingering just north of the area. This will keep a generally E/ESE wind regime in place and allow for afternoon convection to initiate along the east coast sea breeze boundary. Convection will then gradually push inland and west through the late afternoon and early evening hours each day. Models remain fairly consistent in showing a rather sharp gradient of POPs Sunday afternoon with 30-40% for the Atlantic metro areas, and upwards of 70% for the Gulf coast. Then, a return to a more widespread wet and unsettled pattern is shown by guidance during the first half of next week as a trough deepens over the E CONUS. Models also show an associated surface boundary reaching the northern portions of the state in the Monday-Tuesday timeframe. However, regardless of the final outcome, guidance in general show coverage becoming widespread by late Monday. Highest NBM POPs will be well into the 80% range by Tuesday afternoon, and remaining around that range through the end of the work week. Temperatures will remain warm during the long term with afternoon highs in the U80s to L90s, along with Heat Index values in the low-mid 100s each afternoon. Marine Issued at 404am EDT Fri Oct 2 2026 A moderate to fresh east southeasterly breeze will continue across most of the local waters through early next week. Wind speeds may surge close to 20kt at times, with small craft exercise caution conditions likely, especially during the afternoon hours. Scattered to numerous showers and thunderstorms will be possible across the local waters each day through the forecast period. Beaches Issued at 404am EDT Fri Oct 2 2026 A High Risk if Rip Currents remains in effect for all Atlantic beaches through Saturday evening. Please follow all posted safety measures at local beaches.
