| Area Forecast Discussion National Weather Service Miami FL 1000am EDT Thu Mar 30 2023 ...New Issued at 857am EDT Thu Mar 30 2023 There are a few showers around the east coast metro and over the Atlantic waters, but most of South Florida is seeing a pleasant morning in the wake of yesterday's frontal passage. Despite a drying atmospheric column, there will be sufficient moisture to support scattered showers through the early afternoon, primarily over the Atlantic waters, and across Broward and Miami-Dade Counties. An isolated thunderstorm cannot be ruled out, but conditions are much less favorable than what we saw yesterday. Temperatures will be cooler than recent days, peaking in the upper 70s along the east coast, with low to mid 80s across the interior and gulf coast. .SHORT TERM... (Today through Friday) Issued at 239am EDT Thu Mar 30 2023 Models and surface analyses place a weakening frontal boundary stalking just south of the Florida Keys today after a night of much needed rain across SoFlo with the FROPA. Most of Miami beach and areas west through Hialeah saw between 1 and 3 inches of rain in an hour last night, and brief heavy downpours were experienced across much of the SoFlo east coast metro areas. CONS/NBM and ensembles depict mid-level ridging quickly following the FROPA, with high pressure expanding across much of the GOMEX and the peninsula. PWATs (Precipitable Waters) remain just around 1 inch, with enough lingering low level moisture for scattered showers to develop with daytime heating this afternoon. probability of precipitation remain in the 30 percent range with drier air advection in the wake of the FROPA. By Friday, the ridge expands into the western Atlantic, with enough drier air entraining to basically knock down POPs into single digits. This synoptic scenario will suppress any significant rain development with subsidence prevailing across the region. In terms of temperatures, neither the rain activity from last night, nor the drier air advection will have a significant impact in temperatures across SoFlo during the short term. Afternoon highs will hover in the low-mid 80s, while overnight lows will remain in the low 70s near the coasts, and mid-upper 60s inland. Long Term (Friday night through Wednesday) Issued at 239am EDT Thu Mar 30 2023 Models show consensus in keeping mid-level ridging as the dominant Synoptic feature during the long term, while surface high pressure Also expands across the southern half of the peninsula and the West Atlantic through early next week. The ridge gradually flattens and pushes eastward, bringing veering winds from the ENE to a more SE flow during the weekend. Meanwhile, long range models depict a deepening trough/low complex migrating NE across the NE CONUS. An associated front pushes into the SE States and the northern Florida peninsula by Saturday, with winds veering southerly to southwesterly. The above synoptic scenario will allow for advection of moisture from the Caribbean waters, bringing a modest increase in moisture and overall enhanced instability. But models remain fairly conservative with this potential FROPA and keep POPS/Wx coverage in the low-end, isolated range through Monday. There is still plenty of uncertainty in terms of how far south the potential front might be able to push. The official forecast continues to follow a blend of model solutions with mainly a slight chance of showers expected over most east coast metro areas. For the rest of the long term, models bring back surface high pressure across the region with generally E/SE winds in place. Expect afternoon highs to remain in the mid 80s across the east coast metro areas, and into the low 90s interior and west coast areas. A parameter to keep an eye on next week will be increasing heat Index values potentially reaching mid-upper 90s over the Western half of SoFlo each afternoon. Marine Issued at 239am EDT Thu Mar 30 2023 Mainly easterly flow prevails today with high pressure establishing across the area behind a cold front passage. Periods of slightly breezy conditions will be possible Friday, then stronger winds expected during the weekend. Seas will remain in the 2-4ft range today and Friday, then rising into the 4-6ft during the weekend ahead of another front approaching from the north. Beaches Issued at 239am EDT Thu Mar 30 2023 Increasing easterly winds will result in high risk for rip currents for most beaches over the Atlantic coast.
