Area Forecast Discussion National Weather Service Miami FL 227 PM EDT Sun Sep 4 2022 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (Rest of today through Monday) Issued at 210 PM EDT Sun Sep 4 2022 A ridge of high pressure in the western Atlantic will continue to dominate the weather pattern across South Florida for the rest of today keeping a light to moderate easterly wind flow in place. With a dry air mass over the area in the mid levels, this will help to limit the coverage of shower and thunderstorm development this afternoon. As the sea breezes push inland and interact with each other, there will be just enough lower level moisture to support scattered showers and thunderstorms mainly over the interior and west coast. With rather poor mid level lapse rates combined with warming 500mb temperatures, strong thunderstorm development will also be rather limited this afternoon. Most of the shower and thunderstorm activity over the interior and west coast will diminish as the evening progresses. As higher amounts of moisture begin to work into the region from the east later tonight, additional shower and thunderstorm activity is possible over the local waters as well as the east coast metro areas overnight into Monday morning. Low temperatures will remain on the warm side as they will range from the lower 70s across the Lake Okeechobee region to around 80 across the east coast metro areas. Moisture advection will continue to take place over the region on Monday as the latest guidance shows PWAT values increasing during this time frame and ranging between 1.8 and 2.0 inches. This will result in more of a typical late summertime pattern of convective development across South Florida. Scattered showers and thunderstorms will develop along the sea breezes as they push inland. The highest chances of showers and thunderstorms will be over the interior and west coast during the afternoon and evening hours as easterly wind flow will remain in place. High temperatures will continue to rise into the lower 90s across most areas on Monday afternoon with heat index values rising into the triple digits. Some areas across the interior and west coast could see heat index values of 105 or slightly higher later on Monday morning into Monday afternoon. && .LONG TERM... (Monday night through next Saturday) Issued at 210 PM EDT Sun Sep 4 2022 Tuesday-Wednesday: The Atlantic high keeping South Florida in an easterly regime will remain in place through mid-week before beginning to break down. This will keep easterly to southeasterly flow over the area through the first half of the long term period. PWATs will likely be running below 2 inches which will keep convection in the scattered range with greatest coverage over the interior and western portions of South Florida. With light synoptic flow, sea breezes will dominate convection in the afternoon with the west coast sea breeze likely being able to push further inland in the absence of stronger easterly flow. Thursday-Saturday: High pressure begins to retreat mid-week as a strong cutoff low develops over the central United States and drifts Southward towards the Gulf Coast. Surface flow across South Florida will veer more southerly keeping conditions warm and muggy. This will result in a general increase in moisture and lift with precipitation chances increasing as a result. The evolution of the cutoff low will have large implications for rainfall over South Florida so specifics regarding the end of the period are still uncertain, though an uptick in POPs near the end of the period is likely regardless. Convection will still be diurnal in nature and dominated by sea breeze boundaries and outflow boundary collisions as synoptic flow will be light. By the start of the next weekend, high pressure attempts to build back over the area as low pressure retreats poleward. Temperatures will range from the low-mid 90s across the area with heat indices approaching triple digits. && .AVIATION... (18Z TAFS) Issued at 210 PM EDT Sun Sep 4 2022 Mainly VFR conditions will prevail throughout the forecast period. Easterly winds around 10 knots will continue across the east coast terminals this afternoon before becoming light and variable this evening. At KAPF, A west wind flow will develop this afternoon due to the west coast sea breeze developing.Scattered showers and thunderstorms will be possible near KAPF late this afternoon. These storms could bring periods of MVFR or IFR through the early evening hours.&& .MARINE... Issued at 210 PM EDT Sun Sep 4 2022 An area of high pressure in the western Atlantic will continue to bring a light to moderate easterly wind flow to the local waters through the rest of the weekend and into the early portion of the week. Seas will generally remain at 3 feet or less over the Atlantic and Gulf waters through the middle of the week. Scattered showers and thunderstorms will be possible each day. Winds and waves could be locally higher in and around showers and thunderstorms. && && .PRELIMINARY POINT TEMPS/POPS...
