The episode as NWS SJU wrote it up.
The combination of an upper level trough and above normal moisture resulted in a very active afternoon along the municipalities of the interior, north and west of Puerto Rico. The wind gusts associated with the thunderstorm activity caused some trees to fall down on the roads.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS San Juan, PR wrote its last area forecast discussion before the first event at Jun 15, 11:39 AM AST, 3 hours 28 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 1139 AM AST Wed Jun 15 2022 .UPDATE...The shower and thunderstorm activity that affected the local islands diminished significantly in the morning hours. Mostly fair weather was observed during the morning, though dense cloud cover was observed early, cloud cover has been breaking over the past hour. A tropical wave is approaching and the moisture is increasing. This increase in moisture will combine with the diurnal heating, cold mid level temperatures and the mid to upper level instability, to cause showers and thunderstorms by the afternoon. The thunderstorm threat is mainly across the central to northern portions of PR, but isolated thunderstorms and scattered showers could be observed elsewhere. No changes were made to the inherited forecast. && .AVIATION...VFR conds expected early across the terminals, but VCSH is expected from now until around 15/17Z or so. Thereafter, there is a better chance for TSRA, so TJSJ and TJBQ will likely have at least some VCTS, while VCSH is expected elsewhere. That said, TSRA could affect TJSJ and TJBQ at times, but TEMPO would be written on TAF when timing becomes clearer. && .MARINE...Seas up to 5 feet expected today and tonight, with winds generally up to 15 knots. There is a moderate risk of rip currents across most of the local beaches, except some beaches of western PR, which has a low risk. && .PREV DISCUSSION... /issued 502 AM AST Wed Jun 15 2022/ SYNOPSIS... Unsettled weather conditions are anticipated to continue through the end of the workweek due to an upper level trough today, and an approaching tropical wave late today and tomorrow. Saharan dust will follow for the end of the workweek and the weekend, resulting in hazy skies. SHORT TERM...Today through Friday... Overnight thunderstorms and downpour activity were due to a tropical upper tropospheric trough-low (TUTT-low). This activity will continue today as the induced surface trough swings by the islands. Therefore, unsettled weather conditions will prevail through much of the day today. However, the Virgin Islands can expect a short break in rain activity early this morning; however, the potential to observe thunderstorms and showers will return mid-morning into the afternoon. The south, southwest, east, and northeast Puerto Rico can expect showers and thunderstorms in the morning, spreading into the interior, north, and northwest by the afternoon. Under a southeast- easterly wind flow, El Yunque Streamer could produce periods of moderate to locally heavy rain in the San Juan Metropolitan Area. Urban and small stream flooding will likely be with the strongest thunderstorms and downpours, frequent lightning, and thunderstorm winds. An approaching tropical wave will arrive late tonight into Thursday, promoting an unstable and wet pattern across the islands. Also, the upper-level feature will enhance showers and thunderstorms on Thursday. Both GFS and ECMWF indicate plenty of moisture along the air column and favorable instability parameters to observe more organized convection. Weather conditions will slowly improve after late Thursday afternoon as a dry air mass filters from the east. A Saharan Air Layer (SAL) will bring additional African Dust Particles over the skies of PR/USVI creating hazy skies on Friday. Rain activity should diminish significantly on Friday, though afternoon convection with isolated strong thunderstorms will remain possible, especially across the northern half of Puerto Rico. LONG TERM...Saturday through Tuesday... An upper level trough will linger north of the islands through the weekend, while a mid-level ridge builds from the east. At the lower levels, the air mass will be dry due to a Saharan Air Layer filtering in from the east. This should result in hazy skies at least through Sunday. Even under the presence of an upper level trough, the low level dry air and the building ridge should work to limit shower activity along the northwestern quadrant of Puerto Rico during the afternoon hours. By Monday, the upper level low lift into the northern Atlantic, while the mid-level ridge hold aloft, although remaining weak. The pressure gradient will tighten, resulting in stronger easterly winds. This pattern will drag patches of moisture into the local islands. Moisture is expected to increase enough to generate stronger convection each afternoon along the northwestern quadrant of Puerto Rico, with the potential for isolated thunderstorms each day. AVIATION... Unstable weather conditions will prevail today. TSRA will affect JPS thru at least 15/12z. SHRA/TSRA will continue moving across the local flying area and some of them will affect the local terminals. TSRA will develop across the Cordillera Central after 15/18z and could impact JSJ/JBQ, SHRA/isold-TSRA will develop downwind from the Virgin Islands, too. Winds will continue at 10 kt or less, but gusty near SHRA/TSRA thru 15/13z, then from the ESE at 10-20 kt with higher gusts and sea breeze variations. MARINE... Showers and thunderstorms will continue across the local waters today, further increasing later today and on Thursday as a tropical wave approaches. Seas could become locally hazardous around these thunderstorms. Otherwise, moderate to locally fresh easterly winds prevail, resulting in choppy conditions. For the beaches, there is a moderate rip current risk for many of the local beaches. && .PRELIMINARY POINT TEMPS/POPS...
