019 FXUS62 KMFL 270700 AFDMFL Area Forecast Discussion National Weather Service Miami FL 300 AM EDT Thu Mar 27 2025 ...New SHORT TERM, LONG TERM, MARINE, BEACHES, FIRE WEATHER... .SHORT TERM... (Today through Friday) Issued at 300 AM EDT Thu Mar 27 2025 Latest ensemble solutions and global models agree in keeping the region under the firm control of mid level ridging through the short term. Weak high pressure also lingers at the sfc across the SE CONUS. WPC`s latest sfc analyses still show a dry frontal boundary lingering around central Florida today, and while it is not expected to bring any tangible weather impacts, it may help in increasing pressure gradients across SoFlo. The overall synoptic scenario described above will result in breezy/gusty periods over the Atlantic metro areas this afternoon, which should persist through Friday. Winds also gradually veer to a more robust easterly flow by Friday afternoon as the ridge and the weak sfc high pressure slowly migrates eastward, and the aforementioned front dissipates. The air mass remains fairly similar to the previous day with afternoon highs expected to reach the mid-upper 80s over the Gulf coast, and upper 70s to low 80s over the eastern half of SoFlo due to the prevailing robust easterly flow. Similarly, tonight`s lows should also remain around the upper 50s to low 60s inland, and mid to upper 60s near the coasts. && .LONG TERM... (Friday night through Wednesday) Issued at 300 AM EDT Thu Mar 27 2025 To begin the weekend, as a mid-level shortwave trough migrates across the Gulf, there is a chance for rain showers and accompanying thunderstorms on Saturday. Along the backside of the Atlantic high pressure, the veering, southeasterly winds will escort additional moisture into the region. With a rising afternoon temperature and diurnal heating, there will be plentiful moisture to support afternoon and evening showers across South Florida on Saturday. Current model guidance has relative agreement that the peak for shower and thunderstorm activity, with the passage of the mid-level trough and associated surface boundary, will be on Sunday with slow movement across the FL Peninsula as we wrap up the weekend and move into the week. In addition, Sunday may be most active with ensembles forecasting unstable atmospheric conditions supportive of convective activity. Plentiful moisture, with Euro and GEFS ensemble guidance forecasting PWATs averaging 1.5" through the weekend, will support potential for substantial rainfall showers. This would favor the Gulf coast on Saturday, the region as a whole through Sunday, and lingering Monday. Temperatures will generally remain in the lower to mid 80s for highs for most of the weekend. However, the easterly flow and warmer air will allow for some upper 80s or lower 90s to sneak into portions of Southwest Florida and the Everglades by Sunday and Monday. Overnight lows will range from the mid-60s inland South FL and mid 70s along the Atlantic coast. The latest long-term model guidance indicates that there will be a lack of a well-defined high pressure air mass building back into the southeastern CONUS. This will prevent the return of drier air and warm weather early next week after the departure of the frontal boundary. There will be plentiful moisture, warm southeasterly flow, and afternoon diurnal heating that will keep the potential for showers in the long-term forecast as we move into the mid-week. Temperatures, with the southeasterly winds, will rise into the mid- to-upper 80s, with the chance for portions of the SW to reach highs, well above seasonal, in the 90s by Tuesday. && .AVIATION... (06Z TAFS) Issued at 110 AM EDT Thu Mar 27 2025 Generally VFR will prevail during the next 24 hours at all terminals. Moderate easterly winds will become breezy and gusty after 15Z, and remain so through the forecast period. && .MARINE... Issued at 300 AM EDT Thu Mar 27 2025 High pressure is building back into the South Florida coastal waters with overall benign boating conditions continuing until late this morning. Increasing easterly winds will result in speeds reaching advisory levels over the Atlantic waters by this afternoon, with conditions remaining hazardous through Saturday. Some portions of the Gulf waters will also reach advisory levels, but not as prolonged as in the Atlantic marine zones. Conditions should begin subsiding Saturday evening into Sunday morning as winds gradually decrease. && .BEACHES... Issued at 300 AM EDT Thu Mar 27 2025 A High Risk of Rip Currents is expected for all Atlantic beaches starting late this morning and continuing through the weekend. Some periods of elevated surf conditions are likely on Friday, mainly over portions of coastal Broward and Palm Beach counties. Latest model estimates show possible 5-6 ft surf heights for those beaches. The situation will continue to be closely monitored in case an advisory becomes necessary. && .FIRE WEATHER... Issued at 300 AM EDT Thu Mar 27 2025 An elevated fire weather risk is expected this afternoon as relative humidity values may drop into the 34-36 percent range over portions of Mainland Monroe and Collier counties for a few hours. However, wind speeds are expected to remain below critical values. && .PRELIMINARY POINT TEMPS/POPS...
