The episode as NWS MFL wrote it up.
Shortwave troughs crossing the region, and cooler temperatures aloft, led to the ideal environment for an active afternoon and evening on May 19th with widespread showers and thunderstorms. Ample diurnal heating increased instability across the region which lead to numerous strong thunderstorms with the primary hazards of gusty winds and hail.

This morning's 12Z sounding shows a much more moist profile compared which is leading to increased instability, so convection could become more widespread. The predominant SW flow will be weaker today and allow for the east coast sea breeze to push further inland and converge over the interior with the SW winds and/or gulf breeze. Therefore, the highest PoPs and storm chances will be over the interior but the coastal areas will stay have PoPs in the ...New SHORT TERM, LONG TERM, AVIATION, MARINE...40-50% range this afternoon and evening. Convection will taper off in the early evening especially for the coasts, but may linger a few extra hours past sunset over the interior. Entering the weekend tomorrow, an upper-level ridge begins to build in behind the departing trough with moisture staying trapped over the Peninsula. The development of the ridge will lead to winds shifting more easterly on Saturday. Due to lower synoptic forcing created by the ridge, convection will be initiated by the sea breezes and mostly favor the interior again but coastal areas could still see a few showers and storms too. High temperatures will continue to be in the upper 80s to low 90s across South Florida with highest temperatures over the...New SHORT TERM, LONG TERM, AVIATION, MARINE... interior areas. && .LONG TERM... (Saturday night through next Thursday) Issued at 245 PM EDT Fri May 19 2023 Saturday night into Monday... The medium models are showing a developing low just east of NW Bahamas as a cold front shifts southward into the Southeastern Untied States. This will allow for the ridge of high pressure over Central Florida to flatten out allowing fo...New SHORT TERM, LONG TERM, AVIATION, MARINE...r the wind flow over South Florida to be mostly light. Thinto the interior areasis in turn will allow for both the east and west coast sea breezes to develop and push inland each day focusing the showers and thunderstorms over the interior areas during the afternoon and evening hours. However, the metro areas should still see some showers and thunderstorms along the sea breezes as they move through the metro areas. Lows will be in the lower to mid 70s over the metro areas to around 70 over the interior areas each night. Highs will be around 90 over most areas except mid to upper 80s east coast metro areas. Heat indices on Sunday will be around 100 over most areas except mid to upper 90s over the east coast metro areas. Middle of Next Week... The low pressure east of NW Bahamas will dissipate as the cold front over the Southeastern United States stall out. At the same time, the flatten ridge over Central Florida will also dissipate. This will allow for a more south to southwest steering flow to set up over South Florida pushing the west coast sea breeze eastward across the region while the east coast sea breeze remains over the east coast metro areas. Deeper tropical moisture will also start work into South Florida from the Caribbean Sea on the south southwest steering flow which will lead POPs to the likely to categorical range. The PWAT values for middle of next week is forecast to be in the 1.7 to 1.9 inch range which is in the 90th percentile range for this time of year. Therefore, heavy rainfall is a possibility over South Florida with any thunderstorms that do develop. Highs will be also be a little bit cooler for the middle of next week due to the increase cloud cover with mostly in the mid to upper 80s. This will keep the heat indices in the lower to mid 90s. However, the lows will still be in the lower to mid 70s except around 70 over the interior areas. Late Next Week... The front will remain nearly stationary over the Southeastern United States as a mid to upper level low is forecast to develop over the NE Gulf Of Mexico. This will keep South Florida in the south to Southwest steering flow along with the deep tropical moisture. Therefore, POPs will remain in the likely to categorical range with the highest POPs over the east coast metro areas each day. Heavy rainfall will still be possible with any thunderstorms due to the PWAT values remaining in the 90th percentile range for this time of year. There could also be a few strong storms late next week where the sea breezes collide due to the 500 mbs cooling down to -10 to -11C. Will continue to monitor this through this weekend into next week. && .AVIATION... (18Z TAFS) Issued at 245 PM EDT Fri May 19 2023 Afternoon showers and thunderstorms are beginning to develop in the far eastern metro and interior areas as of now and this will continue into the evening. Any storms that develop immediately near or over terminals could lead to MVFR or IFR ceilings with TEMPOs in effect for this. Convection clears up later this evening with skies clearing overnight. && .MARINE... Issued at 245 PM EDT Fri May 19 2023 Seas of 2ft or less will generally prevail through the weekend and into next week, though the Palm Beach waters could see rises to 3- 4ft at times. Otherwise, relatively benign conditions are expected outside of any rough seas caused by thunderstorms. && .BEACHES... Issued at 245 AM EDT Fri May 19 2023 The risk for rip currents is low today for all beaches with a chance for increasing risks particularly for the Palm Beaches this weekend. However, all beaches could see a rise in this potential and it will be monitored. && .PRELIMINARY POINT TEMPS/POPS...
